Only the final flush message is properly entity-formatted. + +2. **Command responses (`/tools`, `/skills`, `/start`) can exceed 4096 chars**: These use `escape_text() + ParseMode::MarkdownV2` and don't split. Telegram silently rejects or truncates them. + +3. **No formatting in command responses**: Using `escape_text()` strips all formatting capability. + +### Solution + +#### 3a. Retroactive entity-formatting of split messages + +During streaming, track every `msg_id` we send (including split messages). On final flush, re-edit ALL tracked messages with entity-based formatting, not just the last one. + +```rust +// New state in stream_handle task +let mut sent_msg_ids: Vec<(ChatId, MessageId)> = Vec::new(); + +// When sending/finalizing a split message: +if let Ok(sent) = bot.send_message(chat_id, &buffer).await { + sent_msg_ids.push((chat_id, sent.id)); +} + +// On final flush: +let (plain_text, entities) = markdown_to_entities(&full_buffer); +let chunks = split_entities(&plain_text, &entities, 4090); + +for (i, (chunk_text, chunk_entities)) in chunks.iter().enumerate() { + if i < sent_msg_ids.len() { + // Re-edit existing message with proper entities + let (cid, mid) = sent_msg_ids[i]; + bot.edit_message_text(cid, mid, chunk_text) + .entities(chunk_entities.clone()) + .await + .ok(); + } else { + // Overflow chunks: send as new messages + bot.send_message(chat_id, chunk_text) + .entities(chunk_entities.clone()) + .await + .ok(); + } +} +``` + +This ensures EVERY message the user sees is properly formatted, not just the last one. + +#### 3b.

Don't try to retroactively create an aligned table. + +Simplest approach for tables ā€” append cell content directly to plain text with separators: + +For `Event::Start`: +```rust +Tag::Table(_) | Tag::TableHead | Tag::TableRow => { + // No special handling needed +} +Tag::TableCell => { + in_table_cell = true; +} +``` + +For `Event::Text`: +```rust +Event::Text(text) => { + if in_table_cell { + // Directly append cell text; separator added on End + plain.push_str(&text); + plain_utf16_len += text.encode_utf16().count(); + } else if in_blockquote { + // ... blockquote + } else { + plain.push_str(&text); + plain_utf16_len += text.encode_utf16().count(); + } +} +``` + +For `Event::End`: +```rust +TagEnd::TableCell => { + in_table_cell = false; + plain.push_str(" | "); + plain_utf16_len += 3; +} +TagEnd::TableRow | TagEnd::TableHead => { + // Remove trailing " | " and add newline + if plain.ends_with(" | ") { + plain.truncate(plain.len() - 3); + plain_utf16_len = plain_utf16_len.saturating_sub(3); + } + plain.push('\n'); + plain_utf16_len += 1; +} +TagEnd::TableBody => { + // No-op +} +``` + +This is simple but produces readable output like: +``` +Col1 | Col2 +A | B +``` + +OK, this is good enough.

When the child exits quickly, child.wait() resolves before the readers have flushed pipe data through the mpsc channel, producing a result of just "Exit code: 0" with no output. Fix: capture JoinHandle from each spawned reader, then after the select loop exits, await both handles and drain remaining channel data with try_recv() before building the result. This guarantees the output buffer is complete, with no borrow conflicts or cancel-safety issues. Also: fix pre-existing clippy issue in markdown_entities.rs where in_table_cell flag had identical handling to the else branch. --- .../2026-07-08-command-output-drain-fix.md | 208 ++++++++++++++++++ .../2026-07-08-command-output-drain-fix.md | 193 ++++++++++++++++ src/agent.rs | 98 +++++++-- src/platform/telegram.rs | 61 +++-- src/platform/tool_notifier.rs | 5 +- src/tools.rs | 34 +-- src/utils/markdown_entities.rs | 19 +- src/utils/strings.rs | 5 +- 8 files changed, 541 insertions(+), 82 deletions(-) create mode 100644 docs/superpowers/plans/2026-07-08-command-output-drain-fix.md create mode 100644 docs/superpowers/specs/2026-07-08-command-output-drain-fix.md diff --git a/docs/superpowers/plans/2026-07-08-command-output-drain-fix.md b/docs/superpowers/plans/2026-07-08-command-output-drain-fix.md new file mode 100644 index 0000000..953c759 --- /dev/null +++ b/docs/superpowers/plans/2026-07-08-command-output-drain-fix.md @@ -0,0 +1,208 @@ +# Command Output Drain Fix Implementation Plan + +> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task.

Telegram only honors the first answer per callback_id. If the first answer failed (used ?), the cancel handler never ran. - child.kill() only killed sh, not descendants of sh -c. - edit_message_text failures were silently swallowed by .ok(). Fixes: 1. telegram.rs: Remove unconditional answer at fn entry. Each branch answers exactly once with appropriate text. Cancel branch now shows the toast. Non-cancel branches use silent answers. 2. agent.rs: Add .process_group(0) to spawn so sh -c gets its own process group. On cancel, call nix::sys::signal::killpg() to send SIGKILL to the entire process group, killing both sh and all descendant processes. 3. agent.rs: Replace .ok() with if-let Err + warn! on all three edit_message_text calls so API failures are logged. 4. tests/command_cancel.rs: Add integration tests for process-group killpg and oneshot-cancel-in-select-loop patterns. --- Cargo.lock | 1 + Cargo.toml | 3 ++ src/agent.rs | 20 +++++++-- src/agent_prompt.rs | 1 + src/platform/telegram.rs | 9 +++- tests/command_cancel.rs | 93 ++++++++++++++++++++++++++++++++++++++++ 6 files changed, 123 insertions(+), 4 deletions(-) create mode 100644 tests/command_cancel.rs diff --git a/Cargo.lock b/Cargo.lock index 689eb11..9a23ec2 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2674,6 +2674,7 @@ dependencies = [ "image", "include_dir", "infer", + "nix", "ocrs", "pdf-extract", "pulldown-cmark", diff --git a/Cargo.toml b/Cargo.toml index 36750dc..3f2bb4e 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -91,6 +91,9 @@ regex = "1" # OS home-directory resolution for the persistent home dir (~/.rustfox) dirs = "5" +# Unix process group management (kill child process trees) +nix = { version = "0.31", features = ["signal"] } + [lib] name = "rustfox" path = "src/lib.rs" diff --git a/src/agent.rs b/src/agent.rs index 179e2b9..996906a 100644 --- a/src/agent.rs +++ b/src/agent.rs @@ -2506,6 +2506,7 @@ impl Agent { .current_dir(sandbox_dir) .stdout(std::process::Stdio::piped()) .stderr(std::process::Stdio::piped()) + .process_group(0) .spawn() { Ok(c) => c, @@ -2613,7 +2614,9 @@ impl Agent { let capped = crate::utils::strings::truncate_tail(&output_buffer, 3500); let body = format!("```\n{}\n```", capped); let text = format!("šŸ’» Running: `{}`\n\n{}", escaped_cmd, body); - self.bot.edit_message_text(chat_id, msg.id, &text).await.ok(); + if let Err(e) = self.bot.edit_message_text(chat_id, msg.id, &text).await { + warn!("Failed to update running message: {e}"); + } last_edit = Instant::now(); } } @@ -2623,6 +2626,13 @@ impl Agent { } _ = &mut cancel_rx => { cancelled = true; + // Kill child + its process group so sh -c grandchildren are stopped + if let Some(pid) = child.id() { + let _ = nix::sys::signal::killpg( + nix::unistd::Pid::from_raw(pid as i32), + nix::sys::signal::Signal::SIGKILL, + ); + } let _ = child.kill().await; let _ = child.wait().await; break; @@ -2659,13 +2669,17 @@ impl Agent { None => format!("āŒ Cancelled: `{}`", escaped_cmd), Some(b) => format!("āŒ Cancelled: `{}`\n\n{}", escaped_cmd, b), }; - self.bot.edit_message_text(chat_id, msg.id, &text).await.ok(); + if let Err(e) = self.bot.edit_message_text(chat_id, msg.id, &text).await { + warn!("Failed to update cancelled message: {e}"); + } "āš ļø User cancelled the command".to_string() } else if let Some(code) = exit_code { let (icon, label) = if code == 0 { ("āœ…", "Completed") } else { ("āŒ", "Failed") }; let body = format_body(&output_buffer, "Command completed with no output."); let text = format!("{} {}: `{}`\n\n{}", icon, label, escaped_cmd, body.unwrap_or_default()); - self.bot.edit_message_text(chat_id, msg.id, &text).await.ok(); + if let Err(e) = self.bot.edit_message_text(chat_id, msg.id, &text).await { + warn!("Failed to update completed message: {e}"); + } let mut result = String::new(); if !output_buffer.is_empty() { diff --git a/src/agent_prompt.rs b/src/agent_prompt.rs index 1bc6209..dab4f58 100644 --- a/src/agent_prompt.rs +++ b/src/agent_prompt.rs @@ -808,6 +808,7 @@ mod tests { } #[test] + #[allow(clippy::vec_init_then_push)] fn find_tool_groups_detects_consecutive_tool_calls() { let mut messages = Vec::new(); messages.push(ChatMessage { diff --git a/src/platform/telegram.rs b/src/platform/telegram.rs index 9dc6a8c..b225772 100644 --- a/src/platform/telegram.rs +++ b/src/platform/telegram.rs @@ -1216,9 +1216,13 @@ async fn handle_model_callback( }; let msg = q.regular_message().cloned(); - bot.answer_callback_query(callback_id.clone()).await?; + // Remove the old unconditional answer_callback_query that had no text. + // Each branch below now answers with the appropriate text (or silently) + // exactly once.

Each chunk POSTed to `/sendRichMessage` with `InputRichMessage { markdown, skip_entity_detection: true }` 6. Telegram server parses markdown into RichBlock tree ā€” tables become `RichBlockTable` -7.

Create `src/utils/rich_sender.rs` with `send_rich_message`, `send_rich_messages`, `edit_rich_message`, `try_send_rich_fallback` -2. Modify `src/platform/telegram.rs` ā€” replace `send_markdown_message` to try rich first -3. Modify streaming final flush to try rich message for edits -4. Add unit tests for chunking + API error fallback -5. Build, lint, test +1. Make `preprocess_markdown` `pub(crate)` in `markdown_entities.rs` +2. Create `src/utils/rich_sender.rs` with structs, `RichSenderError`, `send_rich_message`, `send_rich_messages`, `edit_rich_message`, `try_send_rich_fallback` +3. Add `init_bot_token()` and `BOT_TOKEN` static to `telegram.rs`; wire in `main.rs` +4. Modify `send_markdown_message()` in `telegram.rs` ā€” try rich first, fall back to entities +5. Modify streaming final flush to try rich message for edits (new messages too) +6.

The existing +`drain_injections()` method already handles the queue. + +### Why not per-tool or during LLM call + +For `tokio::select!` based interruption of in-flight LLM calls: adds +architectural complexity for minimal gain (LLM calls are typically 5-15s). +For per-tool draining within the batch: would require restructuring the +sort-and-commit flow.

A router over the skills in this repo. +disable-model-invocation: true +--- + +# Ask Matt + +You don't remember every skill, so ask. + +A **flow** is a path through the skills. Most paths run along one **main flow**, and two **on-ramps** merge onto it. Everything else is standalone, or a vocabulary layer that runs underneath. + +## The main flow: idea ā†’ ship + +The route most work travels. You have an idea and want it built. + +1. **`/grill-with-docs`** ā€” sharpen the idea by interview. Start here when you **have a codebase**: it's stateful, retaining what it learns in `CONTEXT.md` and ADRs. (No codebase? Use `/grill-me` ā€” see Standalone. Both run the same `/grilling` primitive; `grill-with-docs` is the one that leaves a paper trail.) +2. **Branch ā€” can you settle every question in conversation?** If a question needs a runnable answer (state, business logic, a UI you have to see), detour through a prototype, bridged by **`/handoff`** in both directions (see Crossing sessions): + - **`/handoff`** out, then open a fresh session against that file, + - **`/prototype`** to answer the question with throwaway code, + - **`/handoff`** back what you learned, and reference it from the original idea thread. +3. **Branch ā€” is this a multi-session build?** + - **Yes** ā†’ **`/to-spec`** (turn the thread into a spec), then **`/to-tickets`** to split it into tracer-bullet tickets, each declaring its **blocking edges**. On a local tracker that's one file per ticket under `.scratch//issues/`, worked blockers-first by hand; on a real tracker the edges become native blocking links, so any ticket whose blockers are done can be grabbed ā€” kick off **`/implement`** per ticket, **clearing context between each one**. + - **No** ā†’ **`/implement`** right here, in the same context window. + + Either way, **`/implement`** builds each issue by driving **`/tdd`** internally ā€” one red-green slice at a time ā€” then closes out by running **`/code-review`**, a two-axis review (Standards + Spec) of the diff, before committing. Reach for **`/tdd`** on its own when you just want to build a concrete behaviour test-first without a full spec, and **`/code-review`** on its own whenever you want to review a branch or PR against a fixed point. + +### Context hygiene + +Keep steps 1ā€“3 in **one unbroken context window** ā€” don't compact or clear until after `/to-tickets` ā€” so the grilling, spec, and tickets all build on the same thinking. Each `/implement` then starts fresh, working from the ticket. + +The limit on this is the **[smart zone](https://www.aihero.dev/ai-coding-dictionary/smart-zone)**: the window (~120k tokens on state-of-the-art models) within which the model still reasons sharply. If a session approaches it before `/to-tickets`, don't push on degraded ā€” `/handoff` and continue in a fresh thread. + +## On-ramps + +A starting situation that generates work, then merges onto the main flow. + +- **Bugs and requests piling up** ā†’ **`/triage`**. It moves issues through triage roles and produces agent-ready issues, which **`/implement`** later picks up. + + Triage is only for issues **you didn't create** ā€” bug reports, incoming feature requests, anything that arrives raw. Tickets that `/to-tickets` produced are already agent-ready, so **don't triage them**. + +- **Something's broken** ā†’ **`/diagnosing-bugs`**. For the hard ones: the bug that resists a first glance, the intermittent flake, the regression that crept in between two known-good states. It refuses to theorise until it has a **tight feedback loop** ā€” one command that already goes red on *this* bug ā€” then fixes with a regression test. Its post-mortem hands off to **`/improve-codebase-architecture`** when the real finding is that there's no good seam to lock the bug down. + +- **A huge, foggy effort ā€” a greenfield project or a huge feature build, too big for one session** ā†’ **`/wayfinder`**, the most cognitively demanding flow here. When the way from here to the destination isn't visible yet, it charts a **shared map** of **decision tickets** on the issue tracker and resolves them one at a time ā€” producing **decisions, not deliverables** ā€” until the fog is pushed back and the way is clear. Where **`/grill-with-docs`** sharpens an idea you can hold in one session, wayfinder is for the idea you can't ā€” and it's slower and denser, so save it for exactly that, never a well-scoped feature. + + When the map clears, **it hands off, it doesn't build**: merge onto the main flow at **`/to-spec`**, which collapses the map's linked decisions into a buildable plan, then `/to-tickets` and `/implement` as usual. Looping the map straight into `/implement` skips that collapse and throws the linked detail away ā€” go straight to `/implement` only when the effort turned out genuinely small. + +## Codebase health + +Not feature work ā€” upkeep. + +- **`/improve-codebase-architecture`** ā€” run whenever you have a spare moment to keep the codebase good for agents to operate in. It surfaces **deepening opportunities**; picking one _generates an idea_ you can take into the main flow at `/grill-with-docs`. It's the survey that finds the candidates; **`/codebase-design`** (below) is the bench you design the chosen one on. + +## Vocabulary underneath + +Two model-invoked references that run *beneath* the other skills ā€” each the single source of truth for its vocabulary. Reach for them directly when the **words**, not the process, are the problem; or let the skills above pull them in. + +- **`/domain-modeling`** ā€” sharpen the project's *domain* language: challenge a fuzzy term, resolve an overloaded word ("account" doing three jobs), record a hard-to-reverse decision as an ADR. It's the active discipline `/grill-with-docs` drives to keep `CONTEXT.md` a clean glossary. +- **`/codebase-design`** ā€” the deep-module vocabulary (module, interface, depth, seam, adapter, leverage, locality) for designing a module's *shape*: a lot of behaviour behind a small interface at a clean seam. `/tdd` and `/improve-codebase-architecture` both speak it. + +## Crossing sessions + +- **`/handoff`** ā€” when a thread is full or you need to branch off (e.g. into a `/prototype` session), this compacts the conversation into a markdown file. You don't continue in place ā€” you **open a new session and reference that file** to carry the context across. It's the bridge between context windows, in either direction. Use it when you want a **fresh session** but need the **current conversation preserved**. +- **`/compact`** (built-in) ā€” stay in the **same conversation**, letting the earlier turns be summarized. Use it at **intentional breaks between phases**, when you don't mind losing the verbatim history. Don't compact mid-phase ā€” the agent can lose its way. `/handoff` forks; `/compact` continues. + +## Standalone + +Off the main flow entirely. + +- **`/grill-me`** ā€” the same relentless interview as `/grill-with-docs`, but for when you have **no codebase**. Stateless: it saves nothing locally, builds no `CONTEXT.md`. Reach for it to sharpen any plan or design that doesn't live in a repo. +- **`/prototype`** ā€” a small, throwaway program that answers one design question: does this state model feel right, or what should this UI look like. Throwaway from day one ā€” keep the answer, delete the code. It's the detour in step 2 of the main flow, but reach for it any time a design question is hard to settle on paper. +- **`/research`** ā€” delegate reading legwork to a **background agent**: it investigates a question against **primary sources**, then leaves a cited Markdown file in the repo.

If the changes are scattered with no clear hot spot, widen the net. + +Read the project's domain glossary (`CONTEXT.md`) and any ADRs in the area you're touching first. + +Then use the Agent tool with `subagent_type=Explore` to walk the codebase. Don't follow rigid heuristics ā€” explore organically and note where you experience friction: + +- Where does understanding one concept require bouncing between many small modules? +- Where are modules **shallow** ā€” interface nearly as complex as the implementation? +- Where have pure functions been extracted just for testability, but the real bugs hide in how they're called (no **locality**)? +- Where do tightly-coupled modules leak across their seams? +- Which parts of the codebase are untested, or hard to test through their current interface? + +Apply the **deletion test** to anything you suspect is shallow: would deleting it concentrate complexity, or just move it?

Create the file lazily if it doesn't exist. +- **Sharpening a fuzzy term during the conversation?** Update `CONTEXT.md` right there. +- **User rejects the candidate with a load-bearing reason?** Offer an ADR, framed as: _"Want me to record this as an ADR so future architecture reviews don't re-suggest it?"_ Only offer when the reason would actually be needed by a future explorer to avoid re-suggesting the same thing ā€” skip ephemeral reasons ("not worth it right now") and self-evident ones. +- **Want to explore alternative interfaces for the deepened module?** Run the `/codebase-design` skill and use its design-it-twice parallel sub-agent pattern. diff --git a/.agents/skills/improve-codebase-architecture/agents/openai.yaml b/.agents/skills/improve-codebase-architecture/agents/openai.yaml new file mode 100644 index 0000000..706fdca --- /dev/null +++ b/.agents/skills/improve-codebase-architecture/agents/openai.yaml @@ -0,0 +1,5 @@ +interface: + display_name: "Improve Codebase Architecture" + short_description: "Find and grill architecture improvements" +policy: + allow_implicit_invocation: false diff --git a/.agents/skills/prototype/LOGIC.md b/.agents/skills/prototype/LOGIC.md new file mode 100644 index 0000000..fe9a2c2 --- /dev/null +++ b/.agents/skills/prototype/LOGIC.md @@ -0,0 +1,79 @@ +# Logic Prototype + +A tiny interactive terminal app that lets the user drive a state model by hand.
