From 1fd3277cfdc12b7083899087e35c3428b7bf1242 Mon Sep 17 00:00:00 2001 From: bdchatham Date: Mon, 3 Aug 2026 15:31:07 -0700 Subject: [PATCH] chore(seidroid): remove xreview while its approach is reconsidered xreview drove the sei-droid agent inside a managed omnigent Kubernetes sandbox so a review could build, test and inspect a tree rather than only read its diff. It reached working end to end: the reusable workflow, the Python session driver, idempotency, policy, and the structured verdict post. Removing it now is not a retreat from that result. Having the whole shape running is what made the design questions legible, and they are easier to answer on a clean base than by amending a working implementation nobody has committed to yet. The team wants to iterate on the approach before it becomes the thing other repos depend on. Nothing breaks. The caller workflows in sei-chain and platform pin uci v0.0.15 for both `uses:` and `uci-ref`, so they resolve this workflow from history and keep working unchanged. They do continue to advertise a `seidroid xreview` trigger for a feature that is no longer maintained on main, so they should be removed separately rather than left to rot. ai-review is untouched. It is the other seidroid review path and shares nothing with this one beyond the folder. The implementation stays in history at this commit's parent for whatever the next approach reuses.

The trigger workflow's `guard` job (hosted runner, no secrets) checks the comment author - is `OWNER`/`MEMBER`/`COLLABORATOR` and that the command line is exactly `seidroid xreview` - as a whole line, so a comment that merely quotes or discusses it does not trigger. -3.

It fetches the driver at `uci-ref`, mints an omnigent bearer with the - client-credentials grant, and runs the driver. -4. The driver creates one managed `sei-droid` session, drives the review, and writes the - verdict to a file only when a real verdict is produced. -5. In real-post mode the workflow upserts a single `` comment on the - PR, and only when a real verdict was produced. Either way the - session is deleted on exit, including on cancellation. - -## Auth to omnigent - -omnigent exposes an OAuth2 client-credentials grant at `POST /oauth/token`: a machine -`client_id`/`client_secret` pair, no user, exchanged for a short-lived Bearer token scoped -to `sessions`. The reusable workflow mints the bearer at the start of each run over HTTP Basic -(`client_id:client_secret`) with `grant_type=client_credentials`, masks it, and passes it to -the driver as `OMNIGENT_API_TOKEN`. A non-200 or a response without an `access_token` fails -the run loudly rather than falling through to an anonymous request. - -The `uci-default` runner reaches omnigent over the ClusterIP Service -`omnigent.seigent.svc.cluster.local`, so no public ingress is involved. The `client_secret` -is the only omnigent credential GitHub holds; it carries no user identity and is passed as a -masked env var, never a workflow input. - -Inside the sandbox, the agent's `git`/`gh` read the PR through a token vended to the runner -pod, separate from the workflow's `GITHUB_TOKEN`. The workflow's `GITHUB_TOKEN` is used only -to post the verdict comment. - -## Wiring it into a reviewed repo - -**Prerequisite:** the reviewed repo must be able to run jobs on the `uci-default` ARC scale -set, which runs in-cluster and reaches omnigent over the ClusterIP Service. A repo or org -without that scale set cannot schedule the `xreview` job, and the run never starts. - -1. Copy `tools/seidroid-xreview.yml` to the reviewed repo's - `.github/workflows/seidroid-xreview.yml` on its default branch. -2. Pin both refs in it — the `uses: sei-protocol/uci/.github/workflows/seidroid-xreview.yml@...` - line and the `uci-ref` input — to the same uci release tag or commit SHA (a fixed ref, - never a moving tag). Bump both to adopt a new xreview release. -3. Set the `OMNIGENT_M2M_CLIENT_SECRET` repository (or organization) secret to the - client-credentials secret; `secrets: inherit` in the caller passes it through. It is - required for every run: the workflow always mints a bearer to - whether the verdict is posted. - Setting it to `false` enables posting — and enabling posts grants the sandbox agent a - write-capable path to the PR. Read "Before enabling real posts" below and keep it unset - until every item there holds. - -## Security posture - -- **Trusted commenters gate the trigger.** The guard admits only - `OWNER`/`MEMBER`/`COLLABORATOR` comment authors, so an untrusted actor cannot start a run. - Note this authenticates the **commenter**, not the PR author or the code under review: a - trusted member can run the bot over a fork PR's untrusted code, so the reviewed content is - untrusted regardless of who triggered it. -- **What the driver policy does and does not enforce.** The policy accepts the agent's - read/inspect tools by attested identity and declines Write/Edit/WebFetch/WebSearch (and any - MCP or unknown tool) fail-closed, so the turn never hangs on a human and never - blanket-approves a Write/Edit or an MCP/web egress. It does **not** make the agent - read-only: `Bash` is permitted (it is the carrier for `git`/`gh` reads), so `gh`, - `git push`, and `curl` remain reachable inside the sandbox. The read-only guarantee for - untrusted content therefore depends on three controls outside this policy, not on the tool - policy blocking egress: the trusted-commenter gate, the untrusted-content instruction in the - review prompt, and a server-side shell gate against the full command. The first two are in - place; the shell gate is a precondition to confirm before running over untrusted content or - enabling real posts (see "Before enabling real posts"), so treat the read-only guarantee as - not yet fully established until it holds. -- **Untrusted PR content is data, not instructions.** The review prompt instructs the agent - to treat the diff, file contents, commit messages, and title/body as untrusted material to - review, never as directives, and to report an embedded directive as a possible - prompt-injection finding. -- **A run with no verdict posts nothing.** The post step keys on a real verdict having been - produced rather than on the exit code, so a failed or timed-out review leaves no comment and - a teardown-only failure still posts the verdict it did produce. -- **One session per trigger, torn down best-effort.** `concurrency` cancels a superseded - run; the driver traps `SIGTERM`/`SIGINT` and deletes its session on the way out. Under a - hard kill (a grace period shorter than teardown, a signal mid-DELETE) a session can still - leak, so a server-side session TTL is the backstop. The verdict comment is a single sticky - upsert, so re-runs edit one comment rather than stacking. -- **Credential scope.** The `client_secret` is the only omnigent credential GitHub holds; it - is passed as a masked env var (never an input), carries no user identity, and mints a - short-lived bearer scoped to `sessions`. The workflow `GITHUB_TOKEN` is `pull-requests: - write` / `contents: read`. The sandbox `gh`/`git` token is vended to the runner pod by a - rotator, separate from the workflow token, and is currently scoped to a single repo with - `contents: read`, `pull_requests: write`, `metadata: read`. `pull_requests: write` means a - successfully-injected agent could post or approve — which is exactly why the - untrusted-content instruction and the server-side shell gate are load-bearing before real - posting is enabled. - -### Before pointing this at untrusted content - -The agent holds a vended `pull_requests: write` token and an auto-accepted `Bash` tool, so on -untrusted content (e.g. a fork PR) with no server-side shell gate a prompt injection can drive -a real `gh`/`git` write. That risk belongs to running the agent at all, not to whether the -driver posts its verdict, so there is no review mode that mitigates it. Confirm before pointing -this at content you do not control: - -1. **A server-side shell gate is enforced** for the `sei-droid` managed agent (or the agent is - restricted to a structured read-only tool set), so a prompt-injection string cannot drive - `gh` / `git push` / `curl`. -2. **The vended runner token is confirmed minimally scoped** for what review needs, given that - an injection would run under it. -3. **Reviewed content is first-party / trusted, OR item 1 is in place** — the trigger - authenticates the commenter, not the code. - -Running over first-party / trusted content is safe today. Keep the bot off untrusted content -until the items above hold. - -## Status - -The driver has been exercised end-to-end against live PRs: mint, session create, sandbox -launch, the agent reading the PR through the credential bridge, a structured verdict, and -teardown. The **reusable workflow and its thin caller** are being wired into their first repo -now; the first `seidroid xreview` comment there is the comment-trigger path's first real test. - -Known gaps for a follow-up: the verdict currently posts as `github-actions[bot]` rather than -`seidroid[bot]` (posting via the seidroid app token is a later change); and the -driver's Python dependency (`httpx`) is installed at run time rather than hash-pinned. diff --git a/.github/seidroid/xreview/driver/__init__.py b/.github/seidroid/xreview/driver/__init__.py deleted file mode 100644 index ae3fb98..0000000 --- a/.github/seidroid/xreview/driver/__init__.py +++ /dev/null @@ -1,36 +0,0 @@ -"""Headless session driver for the sei-droid xreview bot. - -Drives one omnigent *managed* sei-droid session through a full review -turn on behalf of a PR event, auto-resolving permission elicitations -per an injected policy, extracting the review verdict, and tearing the -session down.
