Provider options cannot + override the function name, argument schema, or other reserved contract fields. +- Workflow callable resolution starts from the admitted workflow definition, + pins its binding fingerprint, and distinguishes acknowledgements from joined + replies. It cannot pair an old argument adapter with a newer same-name binding. +- `FunctionDefinition` carries optional output JSON Schema. Owned result schemas + derive from the actual serialized filesystem, process, job, subagent, web-fetch, + promise-control, attachment-reference, and transfer results. Claude Edit's + creation/editing variants and workflow acknowledgement shapes are explicit. +- MCP discovery retains optional `outputSchema` through cached/native metadata + and deferred full definitions. Search results retain it when it fits their + existing bounds; truncated results direct callers to full definitions. This + schema continues to describe `structuredContent`, not the response envelope. +- `ScriptToolResult` defines successful structured values and failed calls with + optional structured error output. Session effects and attachment admission + stay with the host; formatted provider text is not the script return value. +- Process tools project retained output into `stdout`/`stderr` strings when it + is valid UTF-8, or lossless `stdout_bytes`/`stderr_bytes` arrays otherwise. + Exactly one field per stream is present, including empty strings for empty + output; output schemas enforce this exclusivity. Execution, polling, and kill + variants share this conversion across presentations. Process metadata is + preserved, with `stdout_omitted_at`/`stderr_omitted_at` retaining byte offsets. + The environment protocol keeps raw bytes and direct model calls retain their + existing text formatting. Native QuickJS integration covers parsing string + stdout and handling binary fallback across process polls. Awaitable `media()` + and `file()` helpers now use ordinary blob tools to select output assets. +- `temporal-workflow` owns a validated `CodeExecutionDescriptor` with source and + catalog CAS references, parent identity, and explicit positive execution limits. + It introduces no interpreter dependency.

Core job/sub-agent declarations publish their owned +reply schemas; submission acknowledgements remain distinct from later replies. +Generic joined workflow bindings need a declared reply schema (or an authored +function's declared result); an arbitrary workflow does not inherit the result +schema of its underlying built-in operation. Missing schemas remain callable. + +The second slice implements the session-owned execution path end to end: + +- The parent session exposes typed scope-open, invoke, and scope-close Updates + plus an authoritative report Query. `CodeToolClient`, Rust DTOs, and generated + TypeScript workflow contracts provide the trusted host boundary. +- The session resolves opaque callable bindings from its existing grants and the + current model presentation, including native injected MCP tools. Searchable MCP + tools use the existing discovery/call tools. Changed catalogs reject new calls + through stale scopes instead of silently rebinding them. +- The deterministic harness records scopes, request identities, arguments, + independent waits, and outcomes. Repeated delivery attaches to the admitted + request; reusing an identity with different arguments or a binding is rejected. + The outer model batch remains parked, and code tool results do not create turns. +- The session schedules each code tool call as a Temporal activity using existing + execution implementations, retry/deadline policies, environment readiness, + promise controls, and effect application. Parallel-safe calls share a bounded + window; exclusive calls retain ordering. Workflow-backed calls and explicit + promise waits suspend independently. Approval-required calls fail before the + protected effect, without inheriting an earlier model-call approval. +- Scope cancellation reconciles admitted work, including joined preparation + results arriving after closure. Completed outcomes remain authoritative; + acknowledged model-owned submissions retain their existing ownership rules. + Forced run/session termination records unfinished outcomes as unavailable, + explicitly allowing that an external effect may already have happened. +- Pending Update handlers and in-flight dispatch prevent session rollover or + completion until reconciled. Durable identities and outcomes survive replay. + Public `CodeToolProgress` events preserve contiguous event cursors without + adding conversational tool calls or exposing internal bindings and payloads. + +The third slice implements native JavaScript execution and its host bridge: + +- `codemode` embeds `rquickjs` 0.14 with one fresh runtime/context and dedicated + native thread per execution. It compiles the complete async-function body + before effects, supports async loops, dependent calls, `Promise.all`, and + `Promise.allSettled`, and retains selected `text(value)` output and a return + value. There are no ambient I/O APIs or module loaders. +- A private prelude captures its own intrinsics, creates immutable tool wrappers, + and exchanges JSON arguments/results through bounded queues. Opaque handles + remain pinned to their wrappers. Unsupported values, including undefined + fields, functions, accessors, cycles, non-finite numbers, and sparse arrays, + fail serialization instead of silently changing the payload. +- Positive limits bound source/catalog size, requests, completions, retained + output, heap, stack, total calls, and outstanding calls. Native interrupts and + checks between microtasks enforce cancellation and elapsed time, including + host waits. Limits remain terminal if guest code catches an interrupt error. +- `temporal_runtime::code::CodeRunner` loads and verifies bounded source/catalog + blobs, checks the catalog against an existing unused session scope, and routes + each request through `CodeToolClient`. It does not restore session state, + schedule tool activities itself, or retry JavaScript. A minimal versioned + execution manifest carries names and handles; execution does not need schemas. +- Successful calls resolve to JSON values; failures reject with `kind`, + `message`, and optional structured `value`. Native MCP envelopes remain intact. + An oversized result becomes a guest error while the session still records the + actual successful effect and its content reference. Transport failures report + unknown outcomes. Neither model context nor effect carriers enter JavaScript. +- Normal completion, script errors, cancellation, and preparation failures after + scope verification close admission and reconcile pending calls within a cleanup + budget. A supervised task retains runner capacity through cleanup when its + caller is dropped. The report keeps selected output, interpreter diagnostics, + authoritative per-call outcomes, and any cleanup failure separately. +- Code tool durable completion records now omit model context and effect carriers. + A digest of the full incoming result preserves exact retry checks. Legacy full + results migrate on decode; replay tests verify that effects still apply and + changed retries are rejected without retaining the discarded payload. + +The fourth slice implements the durable lifecycle and session admission: + +- `features.codeMode` grants an ordinary joined `code_execute` tool with a pinned + source/context reference, optional logical tool selection, and bounded limits. + Generated arguments cannot supply routing identities, authority, or CAS inputs. + The parent session resolves the actual callable catalog; an omitted selection + uses its host-callable tools except the outer code tool, while an empty list + permits only local computation. Each call still passes session admission. +- The shared web configuration editor exposes a Code mode toggle for profiles, + sessions, and bot setup. Its collapsed Customize limits link reveals only + timeout, maximum tool calls, and maximum outstanding calls. New grants use all + eligible session tools by default. Other settings have no controls; existing + API-authored values are preserved when editing the visible limits. +- `CodeExecutionWorkflow` uses the generic start/reply/cancellation/recovery + protocol. Retryable preparation opens the scope and persists a minimal catalog; + `code_run` has exactly one activity attempt. Retryable finalization closes the + scope, reads known outcomes, persists a report, and replies to the waiting parent. + Generic workflow starts reject reuse of a completed execution identity so a lost + start acknowledgement cannot start the same invocation again. +- The `code` role polls its own queue, with independent activity slots and a + process-wide interpreter semaphore shared across universes. The default limit + is four interpreters. Capacity wait, bounded input loading, and JS share one + attempt deadline. Heartbeats continue through cancellation, cleanup, and report + persistence. Waiting scripts cannot consume the sessions role's activity slots. +- A missing runner receipt yields an interruption report from the session's + authoritative outcomes without replaying source. Cancellation allows a bounded + runner grace period before finalization. Cancellation observed during + finalization updates the report once while preserving the runner receipt. + If preparation lost its receipt, + finalization fences the same scope using idempotent open/close operations, + preventing a delayed preparation from leaving admission open. +- The model receives selected `text` output, the return value, diagnostics, + outcome counts, and a detailed-report CAS reference. Reports link source, + catalog, outputs, errors, and attachments without inlining every code tool result. + Completed script failures resolve with a report, allowing the model to decide + what to do next. Completed external effects remain committed after script failure. + +The fifth slice implements model-facing JSON Schema presentation: + +- With `features.codeMode` enabled, OpenAI Responses, OpenAI Completions, and + Anthropic Messages append compact return JSON Schemas and script-call/error + guidance to ordinary function descriptions. Names, input schemas, strictness, + provider options, and existing usage instructions are preserved. Disabled code + mode keeps ordinary descriptions unchanged. Tools excluded by `allowedTools` + are explicitly unavailable inside scripts; recursive code execution stays denied. +- The harness supplies the admitted logical selection and workflow completion + facts with the generation request, including them in its fingerprint. It adds + no schema-loading I/O or provider formatting. Workflow routing, recipes, and + authority stay out of this presentation metadata. Pending generation reconstructs + the same metadata after replay. +- The model adapter and script callable resolver share workflow-result projection: + joined calls use their declared reply schema, while submissions describe their + acknowledgement and promise handles. An arbitrary joined workflow with no + declared result does not inherit its underlying built-in's result schema. +- Await materialization uses `tools::concurrency::AwaitOutput`; environment + controls serialize the DTOs in `tools::environment::control`. Their schemas + describe nullable/omitted fields and generic producer payloads. Core job and + sub-agent workflow declarations persist their reply schemas at admission. +- Native injected MCP descriptions distinguish the result envelope from the + server's optional `structuredContent` schema and explain remote errors and + binary-to-`blobRef` conversion. Search/call helpers explain the same contract + for deferred tools and how to emit discovery results for a subsequent script. + Unknown schemas stay unspecified and do not block execution. +- The real-model test now relies on the rendered tool contracts to create timers, + await their handles, and count resolved results; its prompt no longer supplies + return-field names or shapes. + +Validation for the model-facing slice passed: 260 harness, 266 tools, 194 +LLM-runtime, 395 runtime, and 153 workflow library tests; provider baseline and +code-mode presentation tests; three workflow-contract checks; and the exact +workspace Clippy gate. All 19 targeted live tests passed serially: one +schema-driven real-model run, nine code-workflow cases, and nine ordinary +sub-agent lifecycle/media cases. The sub-agent cases validate the new reply +schemas against existing behavior. Code-mode coverage now also runs actual +environment-job and sub-agent workflows, as described below. + +The `CodeTool` naming pass is complete across harness commands/events/state, +Temporal Updates, queries and activities, runtime adapters, public progress +events, generated contracts/TypeScript consumers, tests, and this roadmap. +`CodeExecution` names the outer script/workflow; `CodeToolCall` and +`CodeToolScope` name the ordinary effects and their session-owned admission scope. + +Validation for the lifecycle slice passed: 98 API, 40 API projection, 258 +harness, 266 tools, 153 workflow, and 395 runtime library tests (one runtime test +intentionally ignored), plus five runtime CLI tests. All nine API artifact tests +and three workflow contract tests passed after regeneration. Full TypeScript +checking, 1,296 consumer tests, production/demo builds, workspace formatting, +whitespace checks, and +`cargo clippy --workspace --all-targets --locked -- -D warnings` passed. +Existing HTTP-server tests require localhost access. No provider credentials +are needed for these checks. + +After the naming pass, the scoped Rust unit suites, all 12 API/workflow artifact +checks, full TypeScript checking, 14 SDK tests, 87 transcript/tail tests, docs +checks, formatting, whitespace checks, and the exact workspace Clippy gate +passed again. All 21 runtime code-mode live checks passed serially, including +the real-model and separate-process recovery tests. The real-model test needed +one rerun after its exact model-tool-call assertion failed; its repeatability +remains to be checked when extending presentation coverage. + +Three serialized `code_tools_live` protocol tests passed against local Temporal +and PostgreSQL using a simulated runner and production session activities. +They cover parallel/dependent +calls, joined workflow replies, submit-then-wait, duplicate/conflicting requests, +denied bindings, sibling failure, abandoned client waiters, scope cancellation, +and forced session shutdown. Harness tests also cover replay and late-completion +races. All seven checks in the new `codemode_live` suite passed: six behavioral +tests through the production session path and a fresh-runtime timing diagnostic. +They cover actual JavaScript loops, ordinary and joined parallel/dependent calls, +submit-then-wait, caught errors, sibling failure, cancellation, large results, +preparation errors, and cleanup after dropping the caller. The suite uses fixture +workflows for job/sub-agent replies, without provider credentials. All nine tests +in `code_workflow_live` pass through public feature admission and production +code/session workers on separate queues. They cover looped parallel effects, +submit-then-wait, selected output, partial script failure, deadlines, empty +capability selection, lost runner receipts without source replay, and parent +cancellation with preserved output and closed scopes. They also inject lost +preparation/finalization receipts to verify activity retries without another JS +attempt, supply an unavailable runner report to verify cleanup still happens, +and hold finalization to exercise late cancellation deterministically. Every +completed code-workflow history is replayed offline with no activities registered; +authoritative outcomes and execution counts must remain unchanged. Model responses +are scripted; these cases need no provider credentials. + +`code_worker_process_live` passes an actual process-loss scenario: kill only the +code worker launched by the test after its first effect, start a replacement on +the same queue, and recover through the production heartbeat timeout. Temporal +history must contain one scheduled/started JS attempt; the report preserves the +known effect, marks the missing JS output, and closes the scope. The recovered +history also passes offline replay. + +`code_model_live` passes with the configured real OpenAI model and production +session/code workers. The model writes async JavaScript, runs two timer effects +and one durable wait, selects a compact result, and consumes it in its next turn. +The prompt supplies the task; the provider gets return-contract details from +the rendered tool descriptions. +It requires provider credentials and does not silently skip missing prerequisites. + +`code_capabilities_live` adds two serialized integration tests. A local native +MCP HTTP server exercises injected calls, search and full-definition retrieval, +input/output schema preservation, structured results, a catchable remote error, +and a dependent recovery call. Search-only tools remain absent from the direct +script catalog; explicitly emitted definitions reach the outer model result. +The second test registers a real environment daemon and runs `job_run` alongside +`agent_run`, then `job_submit` alongside `agent_spawn` and one durable `await`. +It checks exact filesystem effects, results correlated to their promise handles, +the admitted environment, owned child sessions with completed runs, and child +closure. Each test uses a fresh universe and separate code/session queues and +cleans up its daemon/server, database records, and stored objects. Model responses +are scripted; job and child completions come from production workflows. +Both live cases pass serially against local Temporal/PostgreSQL/MinIO, with +loopback MCP explicitly allowed. Workspace Clippy and formatting checks pass. + +Eight additional live tests in `crates/codemode/tests/` pass directly against the +public interpreter boundary with real asynchronous filesystem I/O. They cover +parallel reads and dependent writes across loop iterations; committed and +unfinished effects surviving script failure, cancellation, and deadlines; +rejection of late completions; concurrent-runtime isolation; and completion +delivery during continuous microtasks. Real filesystem rejection recovery proves +that an error frees outstanding-call capacity; a fan-out quota case proves caught +guest errors cannot admit excess writes and that admitted effects may still finish. +These fixtures keep I/O in the host and +need no Temporal server or provider credentials. Run them together with the 17 +unit tests using +`cargo test -p codemode --locked -- --include-ignored --test-threads=1`. + +## Purpose and scope + +Code mode lets the model write a short program that calls authorized tools, +combines their results, and returns only useful output. Loops, conditional +calls, parallel requests, and filtering happen without a model round trip for +every operation. This is especially useful for large tool results and fan-out +to sub-agents or jobs. Model services such as transcription, image generation, +and typed decisions can participate later, after gaining ordinary tool support. + +The program runs in Lightspeed's runtime, independently of any attached +execution environment. It can ask an authorized environment tool to execute +a command, but the orchestration script itself is not an environment process. +VFS and environment files remain separate domains accessed through their +existing tools. + +The agreed first-version boundaries are: + +- Normal asynchronous JavaScript: top-level `await`, loops, branching, + dependent effects, `Promise.all`, and `Promise.allSettled`. +- Native QuickJS in the process hosting the `code` role, with a fresh runtime + per execution and a restricted host API. This does not provide Wasm memory + containment. Roles may share one process or run separately from the same binary. +- JavaScript source only. TypeScript transpilation is deferred independently + of the later Wasm integration. +- Tool contracts presented directly as JSON Schema. Generating TypeScript + declarations from those schemas is an optional later presentation change. +- Capabilities derived from the session's existing grants and bindings, + further constrained by the code-mode feature configuration. Every substantive + effect must also be supported as an ordinary Lightspeed tool capability. +- Existing activity policies for individual effects, including their retry, + timeout, concurrency, attribution, and cancellation rules. +- Workflow-backed tools, including `agent_run`, `agent_spawn`, `job_run`, and + `job_submit`, with the existing durable promise semantics. +- One execution attempt for the JavaScript program. On failure, return the + known outcomes and let the model decide what to do next. +- Reject approval-requiring calls before executing the protected effect. + Durable approval suspension and script resumption are outside v1. + +This builds on the existing [architecture](../documentation/how-it-works/architecture.md) +and [workflow-tool protocol](../documentation/how-it-works/tools-and-controller-workflows.md). +It does not introduce another general workflow engine. + +## Execution architecture + +Expose `code_execute` through a trusted workflow-tool declaration using +`Start` delivery and `Joined` completion, like `job_run`. Its recipe starts a +`CodeExecutionWorkflow`. The parent session records the invocation and waits +for the final report using the normal completion promise, reply validation, +and result-recovery protocol. + +Keep script lifecycle and session authority separate: + +| Component | Responsibility | +| --- | --- | +| `CodeExecutionWorkflow` | Own one `RunCode` attempt, its deadline and cancellation, scope closure, and the final report. | +| `RunCode` activity | Host the interpreter, guest promises, local computation, and a narrow trusted effect bridge. | +| Parent session workflow | Admit every code tool call, schedule existing activities/workflow tools, apply session effects, and retain authoritative outcomes. | + +The trusted Rust bridge sends each tool request directly to the parent session. +The code workflow does not relay every request and result. Guest functions do +not receive Temporal clients, gateway clients, or runtime internals. + +```mermaid +sequenceDiagram + participant S as Parent session + participant C as CodeExecutionWorkflow + participant V as RunCode activity / JS runtime + participant A as Existing tool activities + participant W as Bound job or sub-agent workflow + S->>C: Generic workflow-tool start, joined completion + C->>V: Run admitted source once + V->>S: invoke_code_tool Update + S->>A: Schedule admitted ordinary activity + A-->>S: Structured result and effects + Note over S: Commit outcome and session effects + S-->>V: Complete Update / settle JS promise + V->>S: invoke_code_tool Update for workflow tool + S->>W: Existing workflow-tool start / emission + W-->>S: Correlated completion + S-->>V: Complete Update with durable promise outcome + V-->>C: Selected output or script error + C->>S: Close code tool scope / obtain outcome report + S-->>C: Authoritative code tool outcomes + C-->>S: Final report through normal tool reply +``` + +### One session-owned code tool path + +The implemented bridge uses the asynchronous Temporal Workflow Update +`invoke_code_tool(execution_id, request_id, binding_id, arguments_ref)`. +Its handler enqueues admission through the parent session's serialized state +path and awaits the code tool outcome without blocking that path. The session +uses the admitted binding, schedules the existing activity or workflow-tool +operation, and commits the result and effects before completing the Update. +Several requests may be outstanding; state transitions are serialized while +eligible activities can run concurrently. + +The protocol lives in +[`temporal-workflow::code_tools`](../../crates/temporal-workflow/src/code_tools.rs): + +| Operation | Behavior | +| --- | --- | +| `open_code_tool_scope` Update | Bind an execution identity to a pending joined parent invocation, a narrowed tool allowlist, and call limits. The session resolves opaque binding handles. | +| `invoke_code_tool` Update | Admit or reattach to an execution-local request and await its durable outcome. Arguments travel by CAS reference. | +| `close_code_tool_scope` Update | Stop new admission and optionally request cancellation; return the current scope report. Closing does not itself wait for every call to become terminal. | +| `code_tool_scope_report` Query | Read current bindings and per-request status/output references, including completions occurring after closure. | + +Current hard bounds are 32 scopes per run, 1,024 calls per scope, 64 outstanding +calls per scope, 4,096 bindings per scope, and 256 simultaneous Update waiters. +Ordinary activity concurrency and workflow-tool limits still apply. These are +host safeguards; the code-mode feature adds narrower configurable budgets. The +code workflow closes admission, reconciles remaining outcomes under its cleanup +budget, and produces the final report. + +`CodeToolCall` names an ordinary tool call issued by a code-mode script while +the model's outer `code_execute` call remains pending. A `CodeToolScope` governs +those calls under one execution identity. The outer script/workflow is the +`CodeExecution`; its calls have a code tool origin instead of belonging to +another model-produced batch. + +The [harness records](../../crates/harness/src/core/components/code_tool.rs) +provide deterministic scope admission, deduplication, effect validation, waits, +and cancellation. Commands request transitions; events record accepted facts for +replay. The interpreter and all I/O remain outside the harness. Temporal supplies +activity scheduling and retries; this bookkeeping retains the session's domain +authority while its outer call is parked. + +This session-owned code tool operation reuses the ordinary tool implementations. +Temporal supplies transport, task routing, and the request/response mechanism. +Lightspeed supplies admission, correlation, deduplication, and lifecycle +semantics. All script tool calls use this path in v1; do not +split ordinary calls into a second executor-owned path based on a copied +session snapshot. + +Temporal's Rust SDK supports asynchronous update handlers, including waiting +for activities. The repository currently pins SDK 1.0.0. An activity cannot +use a workflow context to schedule ordinary workflow-owned activities, but it +can use a client to send an Update to the session workflow. This does not +require that session to own the `RunCode` activity. See Temporal's +[Rust message-passing documentation](https://docs.temporal.io/develop/rust/workflows/message-passing) +and [task-queue routing](https://docs.temporal.io/task-queue). + +Reuse the actual scheduled activity boundary, not just the Rust function +behind an activity. The implemented `code_tool_invoke` activity delegates to +the existing execution paths and uses the admitted +`ToolExecutionSpec` and +[`tool_call_activity_options`](../../crates/temporal-workflow/src/config.rs). +Calling the same implementation directly from `RunCode` would lose independent +Temporal scheduling, history, retry, and timeout behavior. + +Preserve the distinction between an infrastructure failure eligible for an +activity retry and a tool-level failure returned as data. Retry-safe effects +retain their bounded policies; process and other non-retry-safe work must not +gain retries merely because JavaScript requested it. The code worker does not +dispatch tool activities onto the sessions queue. Each subsystem schedules +its own activities; existing jobs and sub-agents still use their workflow +protocols. + +Using a generic cross-role Update deliberately refines the current +starts/signals convention. It preserves session ownership and avoids a new +custom transport. Scope closure, cancellation, and report retrieval must also +use admitted generic lifecycle operations, with workflow I/O performed through +Temporal workflow messaging or client activities, never arbitrary workflow I/O. + +Each code tool request needs an execution-local stable identity, bound to its +operation and arguments reference. Retrying transport with the same identity +must attach to the original request or return its outcome; it must not start +another effect. This deduplication concerns bridge delivery, not replaying the +program. Cancelling or losing the client-side Update wait does not itself +cancel the admitted tool operation; scope cancellation is explicit. + +### Keep JavaScript ephemeral + +`RunCode` uses a regular activity with `maximum_attempts = 1`, an explicit +deadline, heartbeat, and cancellation handling. Do not configure workflow +retries or application recovery loops that silently launch the source again. +Expected script exceptions and rejected calls should produce a report rather +than become a reason to retry the whole activity. + +Workflow-task replay reconstructs each owner's recorded orchestration without +re-entering the JavaScript heap. If the process hosting the code role dies or +the activity times out, the code workflow closes its code tool scope +through the session, obtains known outcomes, and returns an interrupted report. The +session's code tool call records remain authoritative; do not create a competing +effect ledger in the code workflow. Recreating the JS continuation is outside v1. + +There is no need to dynamically register a new Temporal workflow definition +for each generated script. One statically registered code workflow supervises +the ephemeral interpreter. Making generated source itself a replayable workflow +would introduce determinism, versioning, +and continuation semantics that this design deliberately leaves for later. + +### Crate structure + +The new library crate is `crates/codemode`; extend the existing crates below. +Ship everything in the existing `lightspeed-runtime` binary. A library boundary +keeps the interpreter independently testable and makes its later Wasm migration +local without requiring a separate executable or a general runtime plugin framework. + +| Crate | Responsibility and implementation status | +| --- | --- | +| `codemode` | Implemented native QuickJS adapter, private JS prelude, promise-job driver, bounded JSON bridge, execution limits, cancellation, and selected output. Later Wasm adapter and TS preprocessing. | +| `temporal-runtime` | Session activities, `CodeRunner`, the `code` role/queue, preparation/run/finalization activities, and CAS report storage are implemented. | +| `temporal-workflow` | Code tool DTOs, `CodeToolClient`, session orchestration, and `CodeExecutionWorkflow` with a single-attempt activity lifecycle are implemented. | +| `harness` | Implemented deterministic code tool invocation origins, admission facts, waits, and outcome records preserving session-owned effects and promises. No interpreter or infrastructure I/O. | +| `tools` | Shared callable specifications/bindings, output-schema metadata, and owned result schemas are implemented. The ordinary `code_execute` definition and trusted admission context are implemented. | +| `llm-runtime` | Model-facing presentation of the same resolved tool specifications; provider-native wire formatting stays here. Code-mode descriptions include available return JSON Schema and matching script guidance. | +| `mcp` | Optional output schemas are preserved in discovered metadata and carried onward by runtime discovery and presentation. | +| `api` | Code tool progress telemetry and the public `codeMode` session feature, limits, and generated consumers are implemented. | + +`codemode` has no dependency on Temporal, the harness, session state, tool +implementations, providers, or stores. Its caller supplies JavaScript source, +opaque callable bindings, and execution limits, receives tool requests, and +supplies results through the JSON bridge. Interpreter values, contexts, +functions, and promise handles remain private to this crate. The engine treats +artifact handles as opaque data; the host resolves authorized artifacts. + +`temporal-runtime` depends on both `codemode` and `temporal-workflow` and adapts +between them. `temporal-workflow` must not depend on `codemode`: durable workflow +inputs contain execution identities and source/catalog references, while the +interpreter accepts materialized source and plain values. Keep durable DTOs in +the existing workflow contract and engine-local types in `codemode`; the runtime +loads artifacts and translates results back into durable references. QuickJS +therefore does not enter the workflow dependency graph. + +Two implemented refactors support this structure: + +- **Code tool invocation admission:** separates call origin from the assumption + that every call belongs to the active model tool batch. Code tool requests have + an explicit execution scope and identity, reusing validation, scheduling + policies, and effect application while keeping code tool waiting/completion + state separate from the outer parked batch. The deterministic facts belong + in the harness; Temporal admission/waiting and effectful adapters remain in + their existing crates. +- **Shared callable specifications:** common host-callable metadata and binding + projection now live in `tools`. Direct model tools and code mode consume + the same resolver, including provider presentation adapters. Provider wire + materialization stays in `llm-runtime`; `codemode` has no tool registry or + tool implementation dispatch. + +No new protocol, scheduler, registry, store, or worker-framework crate is +required for v1. Keep code tool contracts in the existing workflow +modules rather than adding a feature-specific transport package. + +### Worker roles and deployment + +The `code` role is part of the existing +[role wiring](../../crates/temporal-runtime/src/roles.rs). It polls its own +task queue for `CodeExecutionWorkflow` and its prepare/run/finalize activities. The sessions role continues +to own code tool admission, activities, effects, and durable promises. +Both deployment choices use the same executable: + +```sh +# All roles in one process (also the default). +lightspeed-runtime --roles all + +# Or run these worker roles in separate processes. +lightspeed-runtime --roles sessions +lightspeed-runtime --roles code +``` + +The default queue is `lightspeed-code`. Set `--code-task-queue` or +`LIGHTSPEED_TASK_QUEUE_CODE` consistently on gateway, sessions, and code +processes when using a custom queue. `--code-max-concurrent-executions` or +`LIGHTSPEED_CODE_MAX_CONCURRENT_EXECUTIONS` sets the interpreter limit per code +process (default four). The code queue must differ from other role queues. + +Other roles are selected as required by the deployment. Running the code role +does not grant code-mode access to a session; session feature admission still +controls that. Preserve the same Temporal start/Update/completion path when +roles share a process. Do not introduce a direct in-memory session shortcut: +moving a role to a separate process should change deployment configuration, +not execution semantics. + +Native QuickJS is linked into the runtime binary; disabling a role does not +remove its code from the executable. Measure the stripped release-size delta +with the selected embedding features. Native execution shares the hosting +process's memory and privileges, including any colocated roles; worker-role +separation is not a per-script process sandbox. Revisit build features or +separate binary packaging when Wasmtime is introduced, without changing the +session protocol. + +## Workflow tools and durable promises + +JavaScript promises and Lightspeed promises serve different purposes. A JS +promise lets the current JS runtime await a response. A Lightspeed promise +records a durable result relationship with ownership, scope, deadlines, and +cancellation. A host wrapper can connect them without making the JS heap +durable. + +The implemented behavior follows the ordinary tool contracts: + +| Script operation | What its JavaScript promise resolves to | +| --- | --- | +| `tools.agent_run(...)` | The joined sub-agent result. | +| `tools.job_run(...)` | The joined job result. | +| `tools.agent_spawn(...)` | The ordinary submission acknowledgement containing a durable promise handle. | +| `tools.job_submit(...)` | The ordinary submission acknowledgement containing keyed durable promise handles. | +| `tools["await"](...)` | A result or wait outcome under the existing promise rules. | + +Handles must be non-thenable data: awaiting a submission should not +accidentally await its completion through JavaScript promise assimilation. +There is no separate `promises` helper in the current guest prelude. A future +convenience helper could wrap the ordinary wait tool without adding a second +promise subsystem. Wait timeouts remain distinct from the underlying promise's +hard deadline. + +Keep the **parent session as the durable holder** in v1. The parent allocates +real promise identities, records admitted invocations, delivers emissions, +validates replies, and resolves promises. The runner bridge receives that +outcome through the code tool call Update and settles the JS wait. Existing +sub-agent preparation and cancellation assume session ownership; moving +ownership to the code workflow would require a broader protocol change. + +The implemented code tool call admission and completion path correlates each call +with the outer invocation and its own request ID. The ordinary per-call activity +rejects workflow-backed tools and `await`, so the code tool adapter reuses their +preparation paths and returns effects or a wait specification to the session. +Workflow-tool validation now accepts a durable code tool origin as well as a model +call. Independent code tool waits preserve the outer suspension; the runner never +fabricates model batches, session events, or promise IDs. + +The parent session must process these admissions, emissions, cancellations, +and resolutions while its outer joined call is parked. This is control-plane +progress, not another model turn. Do not recursively drive the parked model +batch or start a run on the waiting parent. A dependency on another model +turn from that same parent would deadlock. This path is implemented and covered +by live Temporal tests with joined workflow bindings and independent waits. +Requests pass through the session's serialized admission path while the +dispatcher and Update waiters progress independently. Continue-as-new is deferred +while Update handlers, queued work, or in-flight dispatch remain. Rehydration +retains scope/request identities and durable results, and the client addresses +the stable session workflow ID. The code workflow now has bounded activity, cancellation, and cleanup budgets +so a stuck interpreter cannot wait indefinitely before attempting scope closure. + +Allocate durable promise identities atomically at the session owner. Keep +runtime-owned joined promises out of model-facing wait/cancel/detach helpers; +script-local joined waiters only observe their own admitted code tool calls. +In particular, a script must not wait on its own outer completion promise. + +Ordinary code tools can also return session effects and attachments in +addition to output. Their completions must pass through the appropriate +admitted effect-application path, preserving validation and durable state; +returning only their JSON to the runner is insufficient. Commit trusted +effects once before settling the JS call. Subsequent calls must receive the +applicable updated execution facts, such as a new VFS revision or selected +environment. This does not change the immutable authority and bindings +admitted for the execution. Keep intermediate payloads outside conversational +context while retaining their artifact references for the execution trace. + +## Capabilities and configuration + +Enable code mode using `features.codeMode` in the public session configuration. +Internally this is the `code_mode` feature. Its settings +can narrow available capabilities and set execution budgets. They do not +expand environment grants, MCP access, VFS attachments, sub-agent authority, +or workflow bindings. Every substantive effect must correspond to an ordinary +Lightspeed tool capability admitted to the session. Code mode adds composition +and result processing, not a second privileged service API. + +Admission pins session/run identity, source, limits, and optional tool selection +in an immutable host-generated CAS context. The session-owned scope binds the +actual callable handles and registry revision. Mutable execution facts, including +resource selection, remain with the session owner at each call admission; a +stale copy of session state must not overwrite later effects. +The script supplies business arguments; it cannot choose a holder workflow, +task queue, credential, authority reference, or alternate session identity. +Keep runtime checks and existing revocation semantics at the actual effect +boundary. + +Derive the callable catalog from the session's authorized ordinary tools and +their presented specifications. Code-mode capability selection may narrow that +catalog. Ordinary tool declarations remain available to the model alongside +`code_execute`; deferred tools retain the existing discovery/call path. Guessing +a function name must never make an unadmitted operation available. Use stable +logical identities internally, while preserving the exact argument adapter and +result contract associated with the function specification shown to the model. + +Configuration status is: + +| Setting | Implemented | Remaining | +| --- | --- | --- | +| Enablement | Opt-in `codeMode` adds `code_execute` alongside ordinary tools. | Complete for v1. | +| Capability selection | Logical `allowedTools` narrows admitted host-callable capabilities. | Complete for v1. | +| Execution limits | Attempt deadline, memory, stack, source/catalog/request/result/output bytes, and call count. | Additional compute metering if later isolation requires it. | +| Effect limits | Outstanding calls plus existing per-tool retry, timeout, and concurrency policies. | Optional service budgets or narrower per-call settings. | +| Discovery | Existing MCP search/call tools, schema metadata, and bounds; live code-mode discovery/call integration. | Broader actual-model/provider coverage. | + +The implemented configuration uses flat camelCase fields: + +```json +{ + "features": { + "codeMode": { + "timeoutMs": 60000, + "allowedTools": ["concurrency.sleep", "concurrency.await"] + } + } +} +``` + +`allowedTools` contains logical tool IDs, not provider-presented JavaScript +function names. Omit it to allow all granted host-callable tools except the +parent code tool; `[]` permits only local computation. Recursive code execution +is unavailable. Omit `codeMode` to disable the feature. + +Defaults are 60 seconds per attempt, 64 MiB memory, 1 MiB stack, 256 KiB source, +1 MiB each for catalog, request, result, and selected output, 128 calls, and 16 +outstanding calls. Positive hard ceilings are 10 minutes, 512 MiB memory, 8 MiB +stack, 1 MiB source, 8 MiB for the other byte limits, 1,024 calls, and 64 +outstanding calls. `timeout_ms` in a tool call can only narrow the feature's +budget. The joined promise reserves additional time for preparation, cleanup, +and delivery. Additional service-specific budgets remain optional later settings. + +Not every currently advertised tool is locally callable. Provider-hosted +search, fetch, or MCP execution requires a provider turn and may lack a host +adapter. Omit such operations from the code catalog unless a separately +authorized callable implementation exists. Do not silently substitute a +different backend and assume equivalent authority or behavior. + +### Later services and minimal utilities + +Transcription, image generation, and typed decision models such as Jev must +gain ordinary tool support before scripts can call them. Those tools then +participate through the same admitted catalog, permissions, schemas, usage, +and execution policies as direct LLM tool calls. These service tools can be +implemented after the first code-mode release; a code-only `models.*` API is +not the direction. + +Transcription already has a runtime admission and workflow path in +[`transcriptions.rs`](../../crates/temporal-runtime/src/gateway/service/transcriptions.rs). +Reuse that service boundary rather than create a second provider integration. +Adding its tool surface is still separate work. Image generation and decision +models also need their own adapters and tools. See the separate +[typed decision models proposal](later/pNNN-typed-decision-models.md). + +Keep execution utilities small: text/media output, catalog discovery, waits +over authorized durable promises, bounded local values, and scoped blob/artifact +access. Helpers may make existing operations convenient; they must not expose +raw stores, harness methods, provider clients, or arbitrary gateway methods. +Cross-execution persistence needs an explicit bounded contract if added later. + +Media and large results should travel as authorized CAS/artifact handles. +Credentials stay in trusted adapters. Scripts may process structured results +and select text or media for the model without placing every intermediate +payload in model context or Temporal history. + +## Execution descriptor and tool catalog + +Neither the code workflow nor the runner restores session state. Prepare a +small execution descriptor from the parent and pass large immutable material +by reference. For example: + +```typescript +type CodeExecutionDescriptor = { + executionId: string; + sessionWorkflowId: string; + sourceRef: BlobRef; + catalogRef: BlobRef; + limits: CodeExecutionLimits; +}; +``` + +The session retains the authoritative bindings and mutable state. The catalog +is metadata for the execution, not an independent authorization database. +Its manifest can contain function names and opaque binding handles, +description/schema references, and a compact authorized MCP server index. +Retain the referenced artifacts and cache immutable content by digest. Do not +repeat the catalog or source in each code tool request. + +Different consumers need different parts: + +| Consumer | Required information | +| --- | --- | +| Code workflow | Execution/parent identities, source and catalog references, limits, and lifecycle protocol. | +| JS executor | Callable names/binding handles, async dispatcher, helpers, and results. Full schemas are not required to execute a wrapper. | +| Model writing the script | Descriptions, exact argument and return contracts, error behavior, and usage guidance. | +| Session/tool boundary | Admitted operation and adapters, schemas for validation, execution policies, and current applicable state. | + +The bridge transports JSON-compatible values and explicit artifact handles, +not arbitrary JS functions or object graphs. It can map +`tools.my_tool(args)` to an opaque binding plus execution/request identity and +arguments. The session resolves and validates that binding. Knowing a function +name or binding handle alone does not grant access. + +For large MCP inventories, reuse `mcp_find_tools` and `mcp_call` as ordinary +callable tools. They already support bounded browse/search/full-definition +results and named invocation. There is no need to fetch every MCP schema or +create thousands of wrappers before starting a script. Named conveniences can +be added over the same mechanism. Only selected definitions need enter model +context; only used metadata/results need enter runner memory; large payloads +stay out of Temporal history. + +An MCP server record revision pins its registered configuration, not the +remote `tools/list` inventory. Discovery can become stale. Retain the observed +definition where needed for traceability, validate through the existing live +tool boundary, and return useful mismatch errors. Do not claim that a cached +manifest freezes an external server's schema or implementation. + +## Model-facing specification and execution binding + +The core invariant is that **the function name, arguments, return value, and +error behavior seen by the model match the function the script executes**. +Generate the visible specification and its execution binding together. + +Lightspeed already has logical built-in operations with Canonical, Codex-like, +and Claude-like presentations. Reuse the resolved presentation shown to the +model and pin its adapter with the binding. If the declaration says +`tools.Bash({ command })`, do not silently decode canonical `argv` arguments. +A canonical code-mode presentation remains possible only if its declarations +are explicitly what the model sees. Stable logical identity does not by itself +identify the argument schema. Preserve the resolved presentation/binding used +when the model received the declaration, including deferred discovery results; +do not regenerate it against a later provider or configuration while executing +the script. This pinning does not bypass current runtime admission checks. + +Provider-specific normalization belongs at the session/tool boundary. The +runner forwards objects and settles promises; it does not need the model +provider's complete wire tool definitions. TypeScript declarations are +not required for authoring JavaScript: the model can read JSON Schema directly. +Model-facing schema text does not itself validate results or grant permission; +validation and admission remain at the tool boundary. + +### Where JSON Schema appears + +Use JSON Schema as both the machine-readable contract and the initial +model-facing representation. Serialize available schemas directly into tool +descriptions or discovery results; do not build a schema-to-TypeScript +converter in v1. TypeScript source support is a separate, also deferred feature. +Schema metadata, MCP discovery propagation, and description augmentation are +implemented. The placement policy is: + +1. **Directly declared tools:** preserve their ordinary argument + schemas in the provider's native input-schema field. For code-callable tools, + append script invocation guidance and the available return JSON Schema to + their descriptions. Keep these tools directly callable and avoid repeating + their specifications in the `code_execute` description. +2. **The `code_execute` description:** include execution/helper instructions + and explain how scripts call the ordinary tools using their existing contracts. + Names, argument schemas, and tool-specific guidance come from the ordinary + declarations or discovery results. +3. **Discovery results:** return omitted descriptions and JSON schemas on demand, + retaining optional `outputSchema` metadata. A script must output the discovery + result if the model needs to read it and author a subsequent script; merely + loading it into guest memory does not place it in model context. + +For example, a discovery result could include this illustrative specification +for a deferred tool. Its `outputSchema` +describes the value obtained by awaiting `tools.find_users(args)`: + +```json +{ + "name": "tools.find_users", + "description": "Find users matching a query.", + "inputSchema": { + "type": "object", + "properties": { "query": { "type": "string" }, "limit": { "type": "integer" } }, + "required": ["query"], + "additionalProperties": false + }, + "outputSchema": { + "type": "object", + "properties": { + "users": { + "type": "array", + "items": { + "type": "object", + "properties": { "id": { "type": "string" }, "name": { "type": "string" } }, + "required": ["id", "name"], + "additionalProperties": false + } + } + }, + "required": ["users"], + "additionalProperties": false + } +} +``` + +The outer tool's own input schema still describes JavaScript `code` and +execution options. Ordinary declarations and discovery results describe functions +available inside that code; output schemas in descriptions are text, not additional +provider-native return-schema fields. Prefer compact JSON in model requests +and retain existing discovery bounds. Consider TypeScript rendering later if measured +context savings or model reliability justify the converter. + +Pi's hybrid presentation also augments direct tool descriptions, using +TypeScript declarations. It offers `searchTools`, `describeTool`, and +`describeNamespace` for discovery. See Pi's +[loadout/declaration implementation](https://github.com/earendil-works/pi/blob/eb326d265ae0b88489a6d10319307780df827cdf/packages/coding-agent/src/extensions/codemode/tool.ts) +and [code-mode documentation](https://pi.dev/docs/latest/codemode#call-tools). + +Lightspeed adds output JSON Schema to ordinary tool descriptions when code mode +is enabled, using its existing MCP search/call tools for discovery. +Discovery and execution must refer to +the same admitted binding, including deferred tools not in the initial prompt. + +### Structured results and schema gaps + +With code mode enabled, the declaration pipeline appends structured return +schemas to function descriptions. The shared resolver loads +`FunctionToolSpec.output_schema_ref` into `FunctionDefinition`, owned result DTOs +publish serialization schemas, and MCP discovery preserves the server's optional +`outputSchema`. Arbitrary workflow replies without a declared schema and unknown +external result shapes remain explicitly unspecified. + +When extending owned result-schema coverage, use the same metadata for model +descriptions and execution bindings. Where absent, document +the known result envelope and explicitly leave its tool-specific payload +unspecified; do not invent fields or promise a shape inferred from one observed +result. Missing schemas do not prevent tool execution. Preserve descriptions +and error semantics alongside schemas. + +[`ToolInvocationOutput`](../../crates/tools/src/runtime/mod.rs) already +separates structured `output_json`, `model_visible_text`, session effects, and +attachments. Bind a script-visible result projection and describe that exact +shape. The session applies effects; the guest gets structured data and scoped +artifacts, rather than having to parse provider-formatted prose. Preserve MCP +`content`, optional `structuredContent`, and error semantics. Its optional +output schema describes server-side structured content, not the entire response +envelope. Native MCP normalization replaces inline image/audio `data` and +embedded resource `blob` fields with `blobRef` in both `content` and +`structuredContent`; descriptions explain this transformation alongside the +server-declared schema. Remote `isError` becomes a rejected guest promise rather +than an `isError` field in the normalized result. +See the [MCP tool-result contract](https://modelcontextprotocol.io/specification/2025-06-18/server/tools#structured-content). + +## Runtime implementation + +The `codemode` crate embeds native QuickJS through +[`rquickjs` 0.14](https://docs.rs/rquickjs/0.14.0/rquickjs/). QuickJS owns parsing, +JS bytecode execution, objects, promises, and microtasks. A Rust driver manages +entry, requests, completions, limits, and cleanup. Keep all library-specific +values, contexts, functions, and promise handles inside that adapter. + +Create a fresh QuickJS runtime and context for each execution. Evaluate the +trusted helper prelude and parse the submitted async-function body before +executing it. Accept JavaScript only; reject unsupported syntax before effects. +No Wasm artifact, TS compiler, subprocess, or attached environment is needed +in this phase. Synchronous interpreter work runs on a dedicated driver thread +so it cannot block the Temporal worker's async executor. Cloned `CodeRunner` +instances share an explicit semaphore capacity and cleanup budget. + +Expose no ambient filesystem, process, network, credentials, Node APIs, or +unrestricted module loading. Effects go through the bridge. Configure QuickJS +memory and stack limits and an interrupt callback for deadlines/cancellation. +Bound source size, serialization, output, outstanding requests, and repeated +microtask processing; enforce host-call deadlines independently. These are +engine-managed limits, not OS process limits. See the +[QuickJS embedding controls](https://quickjs-ng.github.io/quickjs/developer-guide/intro/). + +This phase deliberately accepts native in-process execution for current +trusted deployments. Restricting the JS API does not contain interpreter or +FFI memory-safety faults; these can affect the hosting process, including other +executions and colocated roles. Stronger containment is later work, not a v1 +guarantee. + +### Async guest-to-host bridge + +Provide one narrow nonblocking request bridge. The shared JS prelude creates +a promise, retains its resolve/reject functions under a request identity, and +sends a bounded JSON request through a native host callback. That callback +enqueues the request and returns immediately. Rust performs the session Update +asynchronously. All ordinary tool wrappers use this boundary. + +Keep the engine boundary small and explicit: + +- Start: JavaScript source, admitted binding metadata, and limits. +- Request: request identity, opaque binding identity, and JSON arguments. +- Completion: request identity and JSON result or explicit error data. +- Output/lifecycle: selected output, terminal report, and cancellation. + +Transport JSON-compatible values and scoped artifact handles. Define how +unsupported JS values are rejected; do not expose native Rust objects, borrowed +buffers, or interpreter handles outside `codemode`. One private engine adapter +inside the crate is enough for v1; no general runtime plugin framework is needed. + +On completion, an event goes to the driver owning that runtime. The driver +delivers it to the prelude to settle the matching promise, then pumps QuickJS's +pending-job queue so the continuation after `await` runs. Completion tasks +must not concurrently enter the same runtime. Guest locals and continuations +remain in memory while the host waits; this is ordinary async execution, not +durable JS state. + +Do not block the host callback on the Temporal operation. That would prevent +the interpreter from issuing later sibling calls in `Promise.all`. Wrappers +return pending JS promises promptly; external effects overlap while guest +execution stays single-threaded. Rust future/promise conveniences may be used +inside the adapter, but do not expose library-specific types to the session +bridge or tool implementations. + +Bound both synchronous guest execution and repeated microtask processing. +The driver waits without consuming CPU when only host calls are outstanding, +but the live heap and execution activity slot remain allocated. + +### Later phase: Wasm isolation + +Replace the native interpreter adapter inside `codemode` with QuickJS compiled +to Wasm, hosted by Wasmtime. Keep the JS prelude, JSON message boundary, tool +catalog, session Update bridge, and code workflow intact. This is a localized backend migration, +not a dependency switch: it requires guest artifact packaging, imports/exports, +linear-memory copying and ownership, job pumping, and limit/trap handling. +Use a compatible QuickJS version and feature set and verify script behavior +against the same contract tests. + +[quickjs-wasi](https://github.com/vercel-labs/quickjs-wasi) provides a candidate +QuickJS-NG Wasm artifact and C interface. Its host library is TypeScript, so a +Rust Wasmtime adapter or small C facade is still needed. Share a Wasmtime +engine and compiled interpreter module; create a fresh Store/Instance and +linear memory per execution. The model's JS source is still parsed by QuickJS, +not compiled to Wasm per request. Replace the native request callback with a +nonblocking Wasm import and deliver completions through the guest interface. + +Evaluate precompiling the trusted interpreter artifact and omitting Wasmtime +compiler features from the release, with matching target/configuration and +runtime versions. Measure actual footprint and latency. Expose only the +required imports, avoiding broad WASI capabilities. Add Wasm memory limits and +fuel/epoch interruption while retaining independent host-call deadlines. See +[precompilation](https://docs.wasmtime.dev/examples-pre-compiling-wasm.html), +the [security model](https://docs.wasmtime.dev/security.html), and +[interruption mechanisms](https://docs.wasmtime.dev/examples-interrupting-wasm.html). + +### Later phase: TypeScript source support + +Add an explicit JS/TS language selection. For TypeScript, use a native Rust +transformation step such as Oxc before evaluating the emitted JavaScript in +the same QuickJS runtime. This does not require Node, Deno, or a `tsc` process. +See [Oxc's Rust transformer](https://oxc.rs/docs/guide/usage/transformer). + +Support annotations, interfaces, aliases, generics, assertions, and `satisfies`. +Transpile without type checking; do not imply that TS annotations enforce tool +contracts. The initial TS phase need not support package fetching, +project/tsconfig resolution, TSX, or decorators. Enums, parameter properties, +and runtime namespaces require transforms beyond type erasure: either support +them deliberately through the chosen +transformer or reject them clearly. Do not promise arbitrary TS-project +compatibility. Preserve source locations for errors and reject invalid source +before executing effects. See [Oxc's TS support](https://oxc.rs/docs/guide/usage/transformer/typescript). + +Keep the compiler dependencies with the code worker. Native TS preprocessing +needs its own source-size, concurrency, and resource bounds even after Wasm +is added; guest limits do not cover it. Merely timing out a wait does not +interrupt synchronous compiler work. This phase does not depend on Wasm or +require generating TypeScript declarations for tool schemas. + +### Outer tool and script output + +Use one ordinary JSON-schema tool initially. The signature below is shorthand +for this design document; the provider receives an input JSON Schema: + +```typescript +declare function code_execute(args: { + code: string, // body of an async function + timeout_ms?: number // may only narrow admitted limits +}): Promise; +``` + +Existing ordinary tool specifications accompany this tool in the model request. +Available return JSON Schemas and script-call guidance are appended to their +descriptions when code mode is enabled. +V1 always interprets `code` as JavaScript; add a language selector in the later +TS phase. +Provider-native freeform source input can be added later as another +presentation of the same logical operation. + +For example, with helper names and business schemas still to be finalized: + +```javascript +const results = await Promise.allSettled( + briefs.map(brief => tools.agent_run({ agent: "researcher", input: brief })) +); + +for (const [index, result] of results.entries()) { + if (result.status === "fulfilled") { + text({ index, result: result.value }); + } else { + text({ index, error: String(result.reason) }); + } +} +``` + +Loops and dependent calls also work: a script can list records, fetch selected +details, filter them, and dispatch jobs for the matches. Local computation +remains inside the JS runtime; only effects cross the activity/workflow +boundary. `ParallelSafe` and `Exclusive` policies still +apply even when the script requests several calls concurrently. They do not +promise isolation from other sessions using the same resource. + +`text(value)`, awaitable `media()` / `file()`, and a bounded JSON return value +are implemented. The helpers compose ordinary blob tools and select admitted +assets for the outer result, as described in +[shared content references and code output](p192-content-references-and-code-output.md). +Only selected output and the compact execution report enter the model's tool +result. The complete code tool call report is stored separately. No separate +named store is planned; persistence uses existing VFS files and retained +blobs. Neither persistent globals nor live-heap continuation is required for v1. +The joined payload is a compact envelope with selected output, diagnostics, +outcome counts, and `report_ref`. `output_available` distinguishes retained JS +output from a missing runner receipt; an empty array alone cannot make that +distinction. The detailed code tool call report lives in CAS. + +### Latency expectations to validate + +Latest local development-profile measurements on 2026-10-08 used 32 fresh +pure-JavaScript executions: init/prelude/compile p50 **0.563 ms**, p95 **0.707 ms**; +thread startup through final report p50 **0.671 ms**, p95 **0.853 ms**. Two ordinary +tool calls in the live suite took **370 ms** and **398 ms**, including session +Updates, CAS, and activities. Its ten-call mixed workflow took **4.84 s** including +preparation and cleanup. These are diagnostic samples, not production benchmarks; +they exclude outer code-workflow startup and activity scheduling. + +Keep interpreter cost separate from durable scheduling and actual tool execution: + +| Part | Provisional expectation | +| --- | --- | +| Native interpreter | Linked into the code worker; no per-script Wasm compilation or module loading. | +| Fresh VM, prelude, and a small script | Initial local observations around 1 ms; validate production builds and load. | +| JS loops/filtering and bridge serialization | Local workload-dependent computation; no Temporal operation per JS statement. | +| Code tool Update plus activity | Plan for tens to hundreds of milliseconds of coordination depending on deployment/load, plus the actual tool runtime; measure before committing a budget. | + +Pi reports approximately 20 ms for worker-thread startup and VM creation in +its implementation, which is not a Lightspeed/native QuickJS benchmark. +Temporal gives an illustrative approximately 50 ms activity-scheduling round +trip, not a complete +Lightspeed code tool call estimate. See [Pi's executor](https://github.com/earendil-works/pi/blob/eb326d265ae0b88489a6d10319307780df827cdf/packages/codemode/README.md#how-it-works) +and [Temporal latency guidance](https://docs.temporal.io/design-patterns/performance-latency-patterns). + +Measure fresh-VM `return 1`, realistic specifications/source, JSON processing, +a local bridge no-op, and a session Update plus no-op activity. Measure Wasm +startup and TS transformation separately when those later phases are prototyped. +Compare sequential and parallel effects and saturated workers at p50/p95/p99. +End-to-end tool latency also includes outer workflow startup, `RunCode` +scheduling, and final reply delivery. Sequential effects accumulate scheduling +cost; parallel effects overlap subject to policy and capacity. Queueing and +retries can substantially increase either. + +## Failure, cancellation, and observability + +Every execution needs a report with its terminal status, selected output, +script error if any, and a reference to per-call outcomes. The session protocol +now distinguishes admission rejection from per-call `pending`, `waiting`, +`succeeded`, `failed`, `cancelled`, and `unavailable` outcomes. `CodeRunReport` +separates script output/errors from the authoritative scope snapshot and cleanup +errors; the code finalizer now stores its durable report and compact outer-tool reply. Where dispatch may have +succeeded but a durable receipt is missing, say that the outcome is unknown; +do not imply that nothing happened or that retrying is safe. + +Build this report from the code workflow's lifecycle result and the session's +authoritative code tool call outcomes, with large material in CAS. It is not a +new replay log for JavaScript. Temporal history alone is not the user-facing +audit interface: project useful execution and code tool call metadata into +existing tracing/result surfaces, including usage and attribution. The current +public event projection emits bounded `CodeToolProgress` lifecycle records so +clients retain contiguous cursors; web and CLI consumers keep these out of the +conversation. Detailed code-workflow reports now live in CAS; richer execution tracing remains planned. + +| Event | Required behavior | +| --- | --- | +| One effect fails and the script catches it | Settle that JS promise according to the wrapper contract; allow further authorized work within budget. | +| Uncaught script error | Stop accepting new effects; settle or reconcile outstanding calls; return the error and known outcomes. | +| Runtime/worker loss or activity timeout | Do not rerun source. Close the code tool scope, retrieve the session's known outcomes, and report interruption. | +| Approval required | Return a failed outcome before dispatching the protected effect. The guest receives a rejected tool promise carrying the error. No durable approval wait. | +| Execution cancellation or deadline | Stop dispatch, interrupt the guest, propagate cancellation according to ownership, and perform bounded cleanup. | +| Remote success without confirmed receipt | Preserve uncertainty and any known remote handle; do not claim exactly-once execution. | + +`Promise.all` rejection does not cancel its sibling calls. Track every +dispatched request independently, including work whose promise the script +never awaits. Once the script ends, stop new dispatch and drain or request +cancellation under the execution's cleanup deadline. The code workflow closes +the code tool scope through the session's generic lifecycle operation. Session +Update handlers may remain pending after the cleanup cutoff. The report then +retains the last known outcomes and a cleanup diagnostic; session reconciliation +continues until the calls settle or the session is forcibly terminated. The session rejects late +requests and keeps late external outcomes attributable without reviving the +script. Transport disconnection alone does not close the scope. Scope closure, +owned-promise cancellation, report retrieval, and code-workflow finalization +are implemented. Runner cleanup has a separate 10-second budget; cancellation +waits up to 20 seconds for a receipt before the finalizer takes over. +A finalizer that exhausts its activity retries fails the workflow; ordinary +workflow-tool recovery then reports that failure to the parent. + +Completed replies root their report graph through the session promise payload. +After parent cancellation, an unaccepted final report may be referenced only by +Temporal's snapshot and is subject to the existing uncommitted-blob grace period +(default seven days). Queryability of a workflow does not pin its blobs forever. + +Keep existing ownership rules for durable submissions. A failed JS waiter +does not erase a session-owned promise or cancel unrelated work. Preserve +durable handles in the report, and distinguish an outstanding bridge request +from work already handed off under an admitted run/session scope. Specify the +scope and cancellation mapping for each wrapper before shipping. Cancellation +is best effort and never means that completed remote side effects were undone. + +Separate code execution activity capacity from session tool activity capacity. +Configure independent worker limits and interpreter threads even when the +roles share a process, so waiting `RunCode` activities cannot starve their +effects. Load-test both combined-role and separate-process deployments. Bound +call counts, payloads, and execution duration so code tool calls cannot exhaust +session or code-workflow history. +Honor existing workflow-tool and promise limits as well; larger code-mode +loops do not implicitly bypass per-run admission limits. + +The Temporal hop adds latency and history overhead compared with a direct +host callback. Measure that cost against avoided model turns. Cached metadata +lookup, formatting, and pure computation stay local; live MCP discovery still +uses the ordinary tool execution path. + +## Comparison with other implementations + +Research snapshot: 2026-10-07. The Lightspeed column describes the proposal, +not delivered behavior. + +| Dimension | Pi built-in code mode | Cloudflare Agents code mode | Proposed Lightspeed v1 | +| --- | --- | --- | --- | +| Execution boundary | Fresh QuickJS Wasm VM. | Fresh Dynamic Worker using Workers' V8 isolates. | Fresh native QuickJS runtime through `codemode` in the `code` role of the shared binary; roles may run together or separately. Trusted deployments, JavaScript only; Wasm and TS later. | +| Effects | Injected tool/model functions route through the host. | Host tool functions or connectors exposed through Workers RPC. | Ordinary admitted tools only; the session owns scheduling and results. | +| Discovery | Typed declarations and search/describe helpers. | Generated typed definitions; durable runtime also offers connector discovery. | JSON Schema in ordinary tool descriptions and discovery results, matched to execution bindings; `code_execute` explains composition. | +| Script recovery | Built-in VM execution is ephemeral; small explicit stored values are separate. | Simple executor is stateless; optional durable runtime supports recorded-call replay around approval pauses. | Script is ephemeral; lifecycle workflow and session-owned effects are durable. | +| Retry boundary | Tool-specific host behavior. | Connector/backend behavior; durable call recording is distinct from an activity scheduler. | Existing per-effect Temporal policies, with no whole-script retry. | +| Approvals | Follow host tool integration. | Simple `createCodeTool` excludes approval tools; durable runtime supports approval and resume. | Reject approval-requiring effects in v1. | + +Pi demonstrates the relevant basic pattern: asynchronous guest JavaScript, +host-routed tools, typed discovery, and model helpers in one sandbox. Its +built-in executor should not be confused with the separate Pi Durable task +system. Lightspeed can adopt the programming model while retaining its own +session authority and effect lifecycle. See the +[original writeup](https://lucumr.pocoo.org/2026/10/6/codemode/), +[Pi documentation](https://pi.dev/docs/latest/codemode), and +[code-mode package](https://github.com/earendil-works/pi/blob/eb326d265ae0b88489a6d10319307780df827cdf/packages/codemode/README.md). + +Cloudflare has two relevant layers: a simple `createCodeTool` path and +`createCodemodeRuntime`, which adds durable execution records, approvals, and +resume behavior. The latter re-executes source after an approval pause and +returns recorded results for previously applied calls, checking call sequence +and arguments. It does not restore a live JS heap, and paused-execution resume +is not a general promise to recover arbitrary worker crashes. Its approval +guidance recommends sequential connector calls where parallel arrival order +could diverge on replay. Lightspeed v1 avoids that replay constraint by ending +an interrupted script and reporting outcomes. See Cloudflare's +[AI SDK integration](https://developers.cloudflare.com/agents/tools/codemode/ai-sdk/), +[durable runtime](https://developers.cloudflare.com/agents/tools/codemode/durable-runtime/), +and [deterministic replay guidance](https://developers.cloudflare.com/agents/tools/codemode/how-it-works/#deterministic-replay). + +Cloudflare's default executor blocks direct outbound networking while allowing +explicit host capabilities over RPC; isolation does not require Wasm. Its +separate Dynamic Workflows package exposes actual workflow steps and retries +to dynamically loaded code. That is another design point, rather than a +requirement for code mode. See +[how code mode works](https://developers.cloudflare.com/agents/tools/codemode/how-it-works/) +and [Dynamic Workflows](https://developers.cloudflare.com/dynamic-workers/usage/dynamic-workflows/). + +[AgentOS](https://github.com/smartcomputer-ai/agent-os/) is useful prior art for +generated programs and typed effects. Its earlier Python agent programs and +later Wasm effect/receipt architecture are different designs. The latter's +[effect contract](https://github.com/smartcomputer-ai/agent-os/blob/ec63cb775306f0728a65a4045b6b0457a025af36/spec/05-effects.md) +is a useful authority-boundary reference. Lightspeed should reuse its existing +Temporal and session machinery rather than import another workflow engine. + +## Implementation seams and acceptance criteria + +The new `codemode` crate provides the interpreter boundary described above. +The main existing seams are: + +- [Session preparation](../../crates/temporal-runtime/src/gateway/service/session_preparation.rs): + feature admission, toolset assembly, and trusted workflow-tool recipes. +- [Tool catalog](../../crates/llm-runtime/src/tool_catalog.rs): logical + identities and resolved model presentation; bind the shown specification to + execution without requiring full schemas in the runner. +- [Runtime definitions/results](../../crates/tools/src/runtime/mod.rs), + [function declarations](../../crates/harness/src/core/components/tooling.rs), + and [MCP discovery](../../crates/temporal-runtime/src/gateway/service/mcp_discovery.rs): + carry output schemas through metadata and preserve structured result projections. +- [Session tools](../../crates/temporal-runtime/src/worker/session_tools.rs) + and [tool activities](../../crates/temporal-runtime/src/worker/activities/tools.rs): + execution bindings, argument validation, effect results, and native MCP policy. +- [Code tool execution protocol](../../crates/temporal-workflow/src/code_tools.rs) + and [session dispatcher](../../crates/temporal-workflow/src/workflows/session/code_tools.rs): + typed Temporal Updates, independent activity scheduling, and outcome recovery. +- [Tool-batch orchestration](../../crates/temporal-workflow/src/workflows/session/tool_batches.rs): + ordinary model-batch execution, retained alongside the scoped call path. +- [Workflow-tool state](../../crates/harness/src/core/components/workflow_tool.rs) + and [promises](../../crates/harness/src/core/components/promise.rs): + durable ownership and correlation. Add only deterministic generic admission + facts here; keep interpreter execution and infrastructure I/O outside the harness. + +Implementation sequence and current status: + +1. **Implemented — contract foundation.** Define the execution descriptor, + matched specification/binding metadata, and script-visible result contract. + Refactor shared callable specifications into `tools`, add output schemas for + owned results, and carry available schemas through the common catalog and + MCP discovery. +2. **Implemented — session-owned execution.** Add code tool admission and + completion for ordinary calls, workflow tools, and promise waits while the + outer joined call is parked. + Reuse activity policies and the session's effect-application path. +3. **Implemented — interpreter and host bridge.** Add `crates/codemode` with native QuickJS + behind the JSON message boundary. Connect guest tool requests to the existing + session Update client in `temporal-runtime`. Demonstrate JavaScript + dependent/parallel effects, guest job pumping, interruption, and engine-managed + resource limits. +4. **Implemented — durable lifecycle and admission.** Add feature admission, the trusted joined code workflow in `temporal-workflow`, + and the `code` role/queue in `temporal-runtime`. Implement single-attempt + lifecycle, scope closure, outcome reporting after runner loss, and bounded + cleanup under the implemented session rollover policy. Ship the existing + runtime binary for both combined and separate-role deployments. +5. **Implemented — model presentation.** Available output JSON Schemas and + invocation/error guidance appear in ordinary descriptions on all three + provider adapters. Owned await/environment schemas and core workflow reply + schemas are filled in; the real-model test uses these contracts without + prompt-supplied return hints. Ordinary tools remain alongside `code_execute`. + TypeScript declaration rendering remains optional. + Transcript projection also identifies code execution as its own activity + family. The web UI uses a distinct code icon/color in call rows and folded + run summaries, with JavaScript and source line count in the compact row; + source remains in the expandable arguments. VFS, blob, job, and injected + MCP calls reuse the existing activity styles. +6. **Remaining — integration coverage and operational validation.** Extend the + existing OpenAI Responses cases to other actual model providers. Native/deferred + MCP and real job/sub-agent runtimes have scripted-model live coverage. + Cover effect retries, parent rollover, + remaining lifecycle failure races, and saturation; improve execution inspection + and measure release footprint and complete lifecycle latency. Worker-process + loss, bounded cleanup, lifecycle retries, and offline code-workflow replay + are already tested. Wasm, TS source support, and new model-service tools are + separate later phases. + +Acceptance coverage must include a loop with multiple effects per iteration, +parallel ordinary calls, dependent calls, joined jobs/sub-agents, and durable +submit-then-wait. Exercise sibling failure, unawaited calls, duplicate bridge +delivery, approval rejection, denied/guessed capabilities, cancellation, and +worker loss after some effects complete. Verify that safe individual activity +retries do not restart the script or repeat completed siblings. Replay tests +must cover any new deterministic code tool admission and completion behavior. + +Verify that the model-visible argument and return specification matches the +actual wrapper and session binding for each provider presentation and deferred +discovery path. Cover JavaScript syntax errors before effects, unknown output +schemas, MCP structured content and errors, and bounded catalogs without loading every +remote definition at startup. Discovery results must reach model context when +explicitly output, while schemas are not required merely to forward a call. + +Verify fresh runtime state per execution, absent ambient I/O APIs, native +memory/stack limits, deadline interrupts, and bounded microtask processing. +These checks do not claim containment of native interpreter faults. Add Wasm +containment/ABI coverage and TS transformation/diagnostics with their respective +later phases, reusing the execution and tool-contract cases. + +Also verify that a parked parent handles code tool completion without a model +turn, that sub-agent ownership/cancellation remains valid, and that saturated +runner capacity cannot starve tool execution. The final model output should +stay compact while every code tool effect remains attributable and inspectable. +Exercise parent rollover, lost Update responses, scope closure, and late +requests/results without duplicating effects or requiring JS replay. +Run interpreter contract cases directly against `codemode` without Temporal, +and integration cases with both colocated and separate code/session workers. +Verify that the workflow crate does not acquire an interpreter dependency. + +The concrete gaps are tracked in [Remaining work](#remaining-work). Keep these +acceptance criteria as regression requirements while presentation and coverage +expand, including specification/binding correspondence and ordinary-tool +capability parity. Wasm package/ABI choices, TS syntax +support, and TypeScript declaration rendering belong to later phases. Approval +replay, persistent JS heaps, code-only model services, and a general +program/workflow deployment system remain outside the first version. diff --git a/docs/roadmap/p192-content-references-and-code-output.md b/docs/roadmap/p192-content-references-and-code-output.md new file mode 100644 index 000000000..606ba3bd8 --- /dev/null +++ b/docs/roadmap/p192-content-references-and-code-output.md @@ -0,0 +1,616 @@ +# Shared content references, blob tools, and code output + +**Status:** Shared content tools, filesystem integration, and code-mode +`media()` / `file()` helpers implemented, 2026-10-08.

Successful tool +effects keep their existing durability when a later script operation fails. +See [Pi's code-mode documentation](https://pi.dev/docs/latest/codemode#store-values) +and [sandbox store contract](https://github.com/earendil-works/pi/blob/main/packages/codemode/README.md#store). + +## Current implementation and gaps + +| Area | Already present | Gap to close | +| --- | --- | --- | +| Blob storage | CAS, streaming/range operations, retention, public blob APIs, and always-available `blob_info` / `blob_read` / `blob_put` tools | No additional storage layer needed. | +| References | Shared resolver accepts full refs, recorded media/file handles, and supported producer descriptors; aliases survive context compaction | Lookup currently pages durable event metadata; it does not restore reducer state or load historical tool bodies. | +| VFS reference | `vfs_reference` selects an immutable version without reading its body and returns a common descriptor with verified size | None for this slice. | +| Environment reference | `env_reference` captures one file into CAS without VFS, using streaming and durable transfer receipts | Directories continue to use existing capture tools. | +| File writes | All presentations accept text or `content_ref`; VFS reuses CAS content and environment writes stream exact bytes | Environment reference writes require a daemon supporting the new file-write transfer direction. | +| File reads | Existing text/image/PDF behavior is preserved; media descriptors compose with blob tools and writers | General binary access uses reference creation and bounded blob reads. | +| MCP and jobs | Resolver accepts existing `blobRef` envelopes and `mimeType` / `mediaType` metadata; job artifact paths can use `env_reference` | Remote URIs still require an explicit fetch capability. | +| Web fetch | Exact accepted body bytes are stored and referenced alongside extracted text, checksum, and source provenance | Historical checksums without stored bytes remain unavailable. | +| Code output | `text(value)`, awaitable `media()` / `file()`, JSON return values, retained per-call reports, and explicit media/file selection | Native formats and aggregate budgets remain those of ordinary tool media. | + +Relevant implementation boundaries are the +[blob APIs](../../crates/api/src/storage.rs), +[blob store](../../crates/harness/src/storage/blobs.rs), +[file-reference tool](../../crates/tools/src/attachments.rs), +[file reads](../../crates/tools/src/fs/tools/read_file.rs), +[file writes](../../crates/tools/src/fs/tools/write_file.rs), +[transfers](../../crates/tools/src/transfer.rs), +[MCP result adapter](../../crates/temporal-runtime/src/worker/mcp.rs), +[job results](../../crates/tools/src/environment/jobs.rs), and +[web fetch](../../crates/tools/src/web/fetch.rs). + +## Content identity and descriptors + +Keep these distinctions explicit: + +| Form | Meaning | +| --- | --- | +| `sha256:<64 hex>` | Immutable bytes in CAS; no inherent filename, MIME type, or per-blob permissions. | +| `media:<12 hex>` | Existing short alias for recorded media. | +| `file:<24 hex>` | Existing short alias for recorded file attachments. | +| VFS path | A location resolved against an attached workspace or snapshot. A live workspace path can change. | +| Environment path | A location on a specific execution machine; capture is required to obtain independent immutable content. | + +A common tool-facing content descriptor reuses existing reference and +attachment types rather than introducing another identity: + +```json +{ + "content_ref": "sha256:<64 lowercase hex characters>", + "byte_len": 12345, + "media_type": "image/png", + "name": "plot.png", + "handle": "media:<12 hex characters>" +} +``` + +The example uses placeholders. `content_ref` and verified `byte_len` are +required for newly resolved descriptors; descriptive fields are optional when +unknown. Names and media types describe a particular use of the bytes. They +are not global mutable properties of the hash. Keep provenance where it is +already available, without treating it as authority. + +Descriptors can also carry the existing `source` navigation object. Names, +MIME types, and provenance travel with supplied descriptors or recorded +attachments. A bare full hash may have no such metadata: it identifies bytes, +not the particular URL or filename through which those bytes were obtained. + +Every successful blob operation returns the full canonical `content_ref` in +its structured descriptor. Short handles supplement that identity; they never +replace it in durable results. `handle` is optional and is present only when +the corresponding alias is registered in the session. A full hash does not +automatically create a media or file attachment. + +| Tool | Reference returned | Short-handle behavior | +| --- | --- | --- | +| `blob_put` | Full ref, verified size, and available content metadata | Does not mint a file attachment/handle merely because content was stored; an already registered handle may be included. | +| `blob_info` | Resolved descriptor with the full ref | Includes a known handle when available; explicit file-reference presentation registers and returns a `file:` handle. | +| `blob_read` | Canonical descriptor alongside requested content/read metadata | Includes a known handle when available; native-media admission registers the corresponding `media:` handle. A range still identifies the original blob, with offsets/counts describing the selected bytes. | + +Full refs work well in code because scripts pass values rather than rewriting +hashes. Short handles remain useful when the model authors a later call or +script. Every content-consuming operation accepts the same reference input: +a full ref, an existing short handle, or a supported descriptor. Calling +`blob_info` first is optional, not a required round trip for every consumer. + +Paths and URLs are explicit sources for their corresponding tools; they are +not accepted as ambiguous reference strings. A snapshot ref identifies a +manifest blob, not a particular file's bytes. Select a snapshot file through +`vfs_reference` with its snapshot/path arguments. + +Keep existing advertised result envelopes usable. In particular, recognize +the owned `content_ref` and existing MCP/job `blobRef` forms at the shared +boundary without recursively rewriting arbitrary external structured data. +Producer schemas must describe the value actually returned to scripts. + +## Resolution, authority, and lifetime + +Build one host-side resolver used by blob tools, file writers, reference +tools, and output admission. It resolves known content, verifies availability +and size, and supplies recorded metadata or supported content detection when +necessary. It must not infer a MIME type from a hash or trust a filename as +proof of format. + +Short aliases resolve against recorded session content, including user inputs, +tool results, handed-off attachments, and completed calls in the current code +scope. Unknown or ambiguous aliases fail explicitly. Do not perform a global +CAS prefix search or silently choose one of several matches. This session +lookup supplies alias identity and metadata; it is not blob authorization. + +Today, the gateway authorizes blob API methods at the universe level and +`PgStore` looks up blobs by `(universe_id, digest)`. Neither the gateway blob +handler nor the store checks whether a session previously received the blob. +There are no per-blob ACLs or session blob ownership checks. + +Preserve that behavior for the new tools. A full reference can address any +existing blob in the runtime's bound universe, including one absent from the +session's recorded descriptors. Validate the ref, existence, size, and requested +operation without requiring prior session admission of those bytes. Do not add +a blob permission registry or treat short-handle lookup as an allowlist for +full hashes. Per-blob authorization would be a separate future design. + +Existing public API authorization, universe isolation, tool admission, and +budgets still apply. Filesystem operations additionally require their existing +source/destination grants. Code-mode `allowedTools` may restrict script calls; +it does not introduce blob-level permissions. Direct calls and scripts use the +same universe-bound storage semantics. + +The parent session remains the tool-admission owner. Prepare alias/metadata +resolution facts in the existing tool execution context and record newly +produced references with the normal completion path before settling the JS +promise. The code worker does not restore the session or access storage directly +from guest code. +Reuse workflow-tool starts/signals and the existing code-tool protocol; add no +feature-specific session transport or cross-role activity dispatch. + +The implementation scans durable session event metadata in pages of 1,000 for +content operations. It collects input media and ordinary/code-tool attachment +records, including records removed from active context. It does not read old +tool result bodies. A future derived index can optimize this lookup without +changing alias or access semantics. + +Recorded results, attachments, workspace manifests, and execution reports retain +their canonical refs through the existing blob graph. Renew admission grace +before publishing a reused reference and record containment edges before its +durable owner is acknowledged. Short handles alone, or hashes embedded only +inside prose, cannot serve as retention roots. + +Resolution must not depend exclusively on active model context. An accepted +reference remains usable while its session/durable owner retains it, including +after compaction, workspace changes, or a later script failure. It does not +remain available forever after owner deletion or retention expiry. Derived +lookup indexes, if needed, must be rebuildable from durable records. + +Successful effects retain their references even if JS output selection is +lost. Existing execution reports make those outcomes recoverable through the +blob tools. Preserve uncertainty after a lost receipt; do not retry the whole +script or fabricate successful output selection from completed calls. + +## Ordinary blob tools + +### Availability + +Register `blob_info`, `blob_read`, and `blob_put` in the base managed-session +tool catalog. All three are available with code mode disabled, without VFS or +an environment, in timer-only sessions, and before any attachments arrive. +There is no separate blob feature switch or feature-family dependency rule. +Incoming content and MCP discovery therefore do not change whether these tools +are declared. This deliberately makes creation of bounded immutable content a +baseline session capability and adds three tool definitions to plain text +sessions. + +Direct model calls can inspect referenced text/JSON, view supported media, +obtain file links, and create text/JSON artifacts without a filesystem. Their +presentation should make these operations clear; raw byte output requires an +explicit binary read mode. Code mode composes the same tool contracts and +does not gain a separate blob API. Its `allowedTools` may still exclude any +blob tool, including `blob_put`; helpers must honor that restriction. + +Storage, request, read, and output budgets apply regardless of caller. +`blob_put` stores new immutable session content; it does not grant permission +to write a workspace or environment. Full refs use the runtime's universe-bound +store; short handles resolve through the session's recorded descriptors. + +### `blob_info` + +Resolve a reference input and return the common descriptor without returning +the body. Use existing stat and supplied/recorded metadata; metadata inspection +does not read file bytes. Native-media presentation performs bounded format +detection when requested through `blob_read`. Report missing, malformed, or ambiguous +references with typed tool errors. A full ref does not need to have appeared +in the session before this call. + +Also provide an explicit file-reference presentation option, with an optional +filename override, that registers a `FileAttachment` and returns its link. +This supplies the ordinary-tool counterpart of `file()` without adding a fifth +blob/reference tool. Metadata inspection alone does not publish an attachment +or introduce native media into context. Define a stable content-derived name +when file presentation is requested without a recorded or supplied name. + +### `blob_read` + +Read bounded data using an explicit format: text, JSON, bytes, or native media. +The implemented `format` values are `text`, `json`, `bytes`, and `media`. +`max_bytes` defaults to 8 KiB and is capped at 1 MiB; `offset` defaults to zero. +Byte-range reads report the full size, returned offset/count, and continuation +offset or completion. Use the existing range interface; do not silently buffer +an entire large object to satisfy a small request. + +Text decoding is strict UTF-8. Specify byte offsets independently of text +character counts. Reads that cut an encoding sequence must have a documented, +lossless policy: exact byte mode always remains available, and text mode must +not introduce replacement characters. JSON decoding requires a complete value +within the read budget; a truncated JSON prefix is not a successful JSON value. +Advertise encoding and truncation in the owned output schema. + +Native-media mode prepares a supported image/PDF descriptor and attachment +through the same validation and limits as ordinary file reads. It does not +return a base64 image body to JavaScript. Direct calls can therefore show +referenced media to the model; code-mode calls receive its descriptor and keep +it available for explicit output selection. + +### `blob_put` + +Store bounded inline content and return its descriptor. Accept explicit, +mutually exclusive text, JSON, and byte inputs; do not guess whether an +ordinary string is literal content, base64, a path, or a reference. UTF-8 is the +text encoding. JSON means the serialized JSON value, not an implicit binary +encoding. Byte representation and encoded-size overhead must be included in +the schema and request budgets. + +The implemented inputs are `text`, `json` (including JSON null), or `bytes` +(an integer array from 0 to 255), with optional `name` and `media_type`. +Stored content is capped at 1 MiB. Request and code-mode budgets apply +separately to the JSON transport representation, including byte-array overhead. + +Use existing content-addressed storage and deduplication. Publish the full ref +and metadata in a retained normal tool result. Optional name/media-type metadata +does not itself select model output, create a file attachment/short handle, or +create a VFS file. Large existing content should be +passed by reference; this tool is not a way around interpreter or request +limits. Upload streams and multipart assembly are outside the initial tool API. + +## Existing producers and filesystem tools + +### VFS reference and reads + +Preserve `vfs_reference`'s metadata-only selection of one immutable file +version, including its explicit snapshot/path recovery path. Add common size +metadata and align the descriptor contract. Keep its explicit file-attachment +behavior and source navigation metadata. + +Keep ordinary file reads line-oriented for text and media-aware for supported +images/PDFs. Their media results should pass directly to content consumers. +There is no need to make every read return a blob or create an attachment: +general binary or oversized files use reference creation followed by bounded +blob reads or reference-based transfer. + +### Write from an existing reference + +Extend VFS and environment write tool contracts to accept exactly one of +existing inline text or a content reference. Preserve existing text calls and +their provider-specific argument names. Reference mode resolves the source +once, pins the immutable bytes, and applies ordinary destination permissions, +path resolution, size limits, and explicit overwrite behavior. + +For VFS, publish the existing blob into the destination manifest and retain +its edges. Do not decode it as text or route it through the JS heap. For an +environment, stream the blob through the existing filesystem/transfer boundary +and verify the completed write. The source filename does not implicitly change +the destination path. Binary bytes are copied exactly. + +Preserve established retry/operation identities for effectful publication; +repeated delivery must not silently overwrite unrelated later edits. Reuse +existing capture publication and transfer receipts instead of inventing a +second filesystem workflow system. State resulting overwrite/retry semantics +in the tool descriptions and tests. + +The implemented writers overwrite existing files, create missing parents, +and reject directory targets. Environment reference writes use a distinct +`writeFile` transfer direction with the existing chunking and receipt engine; +it preserves existing file permissions. Older daemons reject that direction +instead of interpreting it as a less constrained tree replacement. Existing +text calls and materialize/capture wire forms remain supported. + +Hosted transfer operation identities include session, run, turn, batch, call, +and argument identity. Activity redelivery reuses its receipt; a model reusing +the same call ID and arguments in a later run performs a new operation. +Environment capture and file writes use the existing bulk, non-retry-safe +activity policy: failed incomplete transfers are aborted, and the model can +issue a fresh call. Completed receipts remain available for redelivery. + +### `env_reference` + +Capture exactly one environment file into CAS and return a retained descriptor +and explicit file attachment. This is a host-side transfer, not a metadata-only +VFS lookup: the live source is not already an immutable CAS object. It must +work without a VFS mount and for files that native media readers do not accept. + +Reuse capture/streaming primitives for size bounds, stable-file checks, digest +verification, cleanup, and retry receipts. Detect source changes according to +the existing capture policy. A successfully captured reference continues to +identify that version if the environment file is later replaced or removed. +An uncertain/retried operation must not silently capture a different version. +Directories remain the responsibility of existing capture/materialize tools. + +`vfs_materialize` and `vfs_capture` keep their current explicit VFS/environment +roles. They remain useful for directories and bulk work; neither establishes +an overlay or implicit synchronization. Environment job artifact paths can be +converted through `env_reference`, using the job's owning environment and the +session's existing access/selection rules. + +### MCP and job output + +Keep MCP `content`, `structuredContent`, error semantics, and the existing +binary-block `blobRef` conversion. Make admitted binary assets available to the +resolver with their known metadata; do not pretend that a remote resource URI +or HTTP link already names a local blob. Fetching those remains an explicit +granted tool operation. + +Binary job output already has CAS references, sizes, and MIME metadata. Reuse +those as content inputs. Preserve output sequence/truncation fields and the +distinction between retained output segments and live artifact paths. Neither +blob reads nor reference tools can restore process bytes previously discarded +by the environment's output-retention limit. + +## Fix `web_fetch` references + +Persist the exact accepted response-body bytes currently used to calculate its +checksum, before text extraction. Return their retained content descriptor +alongside the current extracted text, source/final URL, HTTP status, content +type, byte count, untrusted marker, and text-truncation flag. + +The reference identifies the original response body, which can differ from +extracted text. If an extracted-text reference is later added, label it +separately. `max_chars` limits visible extracted text; it must not shorten the +stored body. Existing response-byte limits still bound downloads, and a body +that exceeds them must not be advertised as a complete successful fetch. + +For compatibility, the current `sha256` field may remain as a checksum alias +equal to the new descriptor's full ref. New consumers should use the explicit +content descriptor. Existing historical fetch results cannot be made readable +without their bytes; report a missing blob rather than silently re-fetching a +potentially changed URL. Record proper result-to-body containment edges and +preserve source provenance when the content is read again. + +Preserve the current web network policy, redirect checks, supported content +types, and source labeling. Arbitrary binary URL download is a separate +capability extension, not a prerequisite for fixing existing `web_fetch`. +Provider-native fetch results remain provider-owned; this change concerns the +Lightspeed tool implementation and must not fabricate raw response bodies for +providers that did not return them. + +## Code-mode output: `media()` and `file()` + +Code mode provides two awaitable output helpers: + +```javascript +const asset = await tools.blob_info({ ref: "media:" }); +await media(asset); // Native image/PDF input for the model. +await file(asset, { name: "plot.png" }); // A file attachment/link. + +// Raw content uses the same ordinary storage capability. +await media({ bytes: pngBytes }, { media_type: "image/png" }); +await file({ text: report }, { name: "report.txt", media_type: "text/plain" }); +``` + +Keeping admission asynchronous lets +scripts catch missing-reference, unsupported-format, and size errors before +continuing. They accept a supported reference/descriptor or an explicit inline +source object, avoiding ambiguity between text content and reference strings. +Both return the admitted ordinary-tool descriptor. Options may supply `name` +and `media_type`; file presentation uses the supplied or recorded name and +otherwise provides a deterministic content-derived filename. A producer +descriptor remains a reference even if it also contains text or byte-range +data: passing a `blob_read` result selects its original immutable content. + +The helpers are thin wrappers over admitted blob operations plus a private +typed-output emitter. `media()` uses native-media read/admission; `file()` uses +explicit file-reference presentation. Inline sources first use `blob_put`. +These underlying calls follow ordinary session tool scheduling, tracing, +retry, and call budgets. Missing capabilities fail normally. Helpers do not +open paths, fetch URLs, or gain broader storage access. Reference-based output +does not load large bodies into JavaScript. + +`text()` remains synchronous and retains JSON-compatible values. A JSON return +value remains a separate final value. A private receipt records ordered text +indices and media/file admission request IDs. The native emitter accepts only +successfully completed helper admissions and accounts for their descriptor bytes +under the existing output budget. Passing an object with a `type`, `kind`, or +`attachments` field to `text()` does not select an asset. Parallel helper calls +take their place when their admission completes and they emit. + +Finalization verifies each selection against the session's authoritative +completed tool attachments. The compact result's `output` array interleaves +original text values with the existing attachment envelopes (`{kind, data}`). +Its top-level `attachments` list carries the actual selected assets into joined +completion, provider media lowering, and existing client file/media views. +Provider-native tool results still precede their companion media. Historical +interpreter receipts without the new selection field retain their text-only +meaning. + +Tool-produced attachments remain recorded at the session owner. At outer +code-tool completion, materialize only explicitly selected media/file outputs +through the existing attachment and companion-context-entry path. Intermediate +assets stay in execution records. Do not automatically expose every image an +MCP tool or file read returned inside a script. + +Native media supports the existing image formats and PDF, subject to existing +content validation, normalization, provider capability handling, and aggregate +budgets. Preserve the original blob for downloads even when the provider sees +a resized derivative. Arbitrary documents can be delivered as files; DOCX, +audio, video, and other formats do not become native model inputs merely +because their bytes are available. Additional conversions/formats are later +ordinary tool capabilities. No `image()` alias or separate `audio()` helper is +needed for this slice. + +Selected output follows existing partial-result semantics. Ordinary blob +admission failures reject in JavaScript and can be caught; completed effects and +earlier selected outputs remain. Interpreter byte, call, and outstanding-call +budget violations remain terminal execution errors even if caught by JavaScript. +On script failure, retain any valid selected-output receipt already available. +Finalization applies the existing limits of eight native media items and 128 +file attachments per result. An invalid, missing, or over-cap selection adds +`output_errors` with its selection index, kind, +request identity when applicable, and diagnostic message. Valid siblings stay +selected; an otherwise successful report becomes failed. Finalization and late +attachment reads retry transient storage errors without rerunning JavaScript; +unavailable content is explicitly reported rather than silently claiming +delivery. After interpreter loss, distinguish retained tool outcomes from missing +output-selection receipts. +Unawaited helper work follows the existing cancellation policy. + +File output registers a usable attachment and its short link; it does not +automatically load the document into model context or publish it outside the +session. Existing successful-final-answer selection controls sub-agent handoff. +Historical client views and attachment links must keep resolving the admitted +original content. + +## Crates and contracts + +- `harness`: reuse `BlobRef`, media/file descriptors, attachment records, and + deterministic completion/effect application. Add only provider-neutral facts + actually needed for admission or durable results. No storage or filesystem I/O. +- `tools`: own shared content argument/result DTOs, derived JSON Schemas, + reference resolution interfaces, blob tool definitions, file-tool projection, + and the `web_fetch` body-reference contract. +- Runtime/store adapters: supply recorded alias/metadata facts, execute CAS/file + operations, preserve metadata/provenance and retention edges, and prepare + media/file attachments. Reuse existing storage and transfer protocols. +- `codemode`: own only source/helper behavior, bounded JSON/native callbacks, + and typed selected-output receipts. No session restore or direct store access. +- `temporal-runtime` / `temporal-workflow`: preserve ordinary session-owned + tool effects and separate code execution. Carry the selected-output contract + and finalize attachments through the generic workflow-tool result path. +- `llm-runtime` and projections/clients: reuse provider-native media lowering + and attachment presentation; update only what the new selected-output path + requires. + +The implemented tools own their names, descriptor placement, reference-input +unions, read encodings, file-presentation option, and limits in Rust DTOs and +JSON Schemas. Keep those as the source of truth for schemas and execution. +Selected-output receipts stay within the interpreter and runtime report boundary; +the existing workflow attachment contract carries their admitted results. +Regenerate public API/TypeScript consumers when public wire DTOs change and the +workflow contract when execution receipts or result contracts change. Do not +hand-edit generated artifacts or rewrite historical stored result payloads. + +## Delivery plan and acceptance + +1. **Shared references and ordinary blob tools.** Finalize owned contracts, + implement the resolver and core registration of `blob_info`/`blob_read`/`blob_put`. + Include direct file-reference and native-media presentation, retention, + bounded reads, and useful errors. Verify use with code mode disabled and + without other feature families, as well as script allowlist enforcement. +2. **VFS/file integration.** Add write-from-reference across existing write + presentations and align VFS reference/media descriptors. Reuse VFS blobs and + host-side environment transfer. Verify metadata, exact bytes, overwrite + behavior, and ordinary text-call compatibility. +3. **Environment references and producer interoperability.** Add `env_reference` + independent of VFS, integrate MCP/job descriptors, and exercise capture, + subsequent writes, and ref reuse after source changes. +4. **Persist `web_fetch` bodies.** Store and retain response bytes, expose their + descriptor, and preserve extracted text, limits, and source provenance. +5. **Selected media and file output.** Implement awaitable `media()`/`file()`, + typed receipts, finalization, provider lowering, and client presentation. + Validate direct-call parity and end-to-end model use. + +Implementation progress: + +- [x] Shared descriptor/input schemas, full-ref lookup, and session alias resolution. +- [x] Core blob tools, existing universe isolation, limits, and durable retention. +- [x] VFS/environment write-from-reference and existing producer alignment. +- [x] Environment file references without VFS. +- [x] Stored and usable `web_fetch` body references. +- [x] Code-mode media/file helpers and selected-output delivery. +- [x] Shared-content schemas, provider catalog fixtures, roadmap progress, and + end-to-end tests for the implemented tools. +- [x] Selected-output contracts and existing client attachment integration. +- [x] Final helper validation: unit/schema checks, native integration, workflow + live tests, actual-model execution, and workspace Clippy. + +Implementation validation includes native tool tests, metadata-only VFS tests, +real daemon streaming/receipt tests, provider request fixtures, and live +Temporal/PostgreSQL/object-store flows. The helper validation passes 28 native +interpreter unit tests, nine native live tests, and 15 workflow live tests using +real JavaScript and production workflows with a scripted model. Two actual-model +live tests pass, including a model-authored helper script that presents an image, +identifies its color on continuation, and links the generated file. Selected +images and PDF documents also pass native request-lowering checks for OpenAI +Responses, OpenAI Completions, and Anthropic Messages; file-only documents are +excluded from native model input. Runtime tests cover selection validation, +partial failures, aggregate caps, and transient-storage retries. Tools, +LLM-runtime, and runtime unit suites, provider schema/catalog checks, and +workspace Clippy pass. Environment live tests cover +all three provider presentations, files larger than native-media limits, +read-only grants, exact binary restoration, and fresh captures across runs +that reuse call IDs. + +Acceptance tests should cover complete data flows, not just individual shapes: + +- All three blob tools are present with no optional features, with timers only, + and with code mode disabled. Adding attachments does not toggle the catalog. + Direct calls can create/read a text artifact and obtain its file link; a + code-mode allowlist can exclude each corresponding script capability. +- Every successful blob result carries the full canonical ref. Optional handles + resolve to that same content; storing a new blob does not implicitly create + an attachment. Test reuse of existing aliases and explicit file/media + presentation, including range reads that preserve the original blob identity. +- A script stores JSON, receives a reference, and a later script reads it; a + VFS JSON file can serve as a named location when the session has VFS. +- A user-supplied media handle resolves, is copied to VFS or an environment, + and remains pinned to its original bytes after the destination changes. +- An MCP image or job binary-output ref can be inspected, read, saved, and + selected for output without copying its entire body through JS. +- A binary environment file is captured without VFS, survives source removal, + and can be restored from its reference. Test changing files, oversized input, + transfer interruption, conflicting destinations, and repeated delivery. +- A truncated `web_fetch` text preview still has a readable complete accepted + response body; raw HTML and extracted text are not confused. Historical + checksum-only results fail honestly when no body exists. +- Direct tools and code mode use identical universe-bound blob semantics. A + known full hash in the bound universe works even without a prior session + descriptor; a blob present only in another universe does not. Short-handle + lookup remains session-based. Cover malformed refs, unknown/ambiguous aliases, + missing or collected blobs, forged descriptor metadata, inline storage + excluded by the script allowlist, and refs created earlier in the same script. +- Exercise empty content, Unicode/range boundaries, binary fallback, JSON parse + failures, EOF, request/result limits, and aggregate selected-output budgets. +- Verify retention and resolution through script failure, cancellation, lost + output receipts, compaction, replay, restart, and session cleanup. A blob + printed only inside prose must not be mistaken for an admitted reference. +- Verify `text()` data cannot select media, unselected assets do not enter model + context, PDFs differ from file-only documents, and valid partial output is + retained when another selected item fails. +- Exercise image/PDF native requests and file links on supported adapters, + including existing media normalization and historical attachment views. + Include a real-model script that moves a reference through tools and emits + selected media/file output; serialize credentialed Temporal suites. + +Use scoped unit/integration checks during each slice, replay coverage for any +deterministic state change, contract freshness checks when relevant, and the +workspace Clippy gate before a Rust PR.
