On a `seidroid xreview` comment it runs the trusted-commenter guard, fetches the - driver at the caller's `uci-ref`, mints the omnigent bearer, drives the review, and posts - the verdict as one sticky PR comment. Callers reach it with `uses:`. -- `driver/` — the session driver the reusable workflow runs. Creates exactly one managed - `sei-droid` session, drives it through a review turn, auto-resolves the agent's permission - prompts against a read-only policy, extracts the verdict, and tears the session down. - Speaks the omnigent REST API directly over `httpx`. `driver/tests/selftest.py` covers the - settle/nudge and verdict-parsing logic with a scripted fake client - (`python .github/seidroid/xreview/driver/tests/selftest.py`). -- `tools/seidroid-xreview.yml` — the **caller template**. Copy it into the reviewed repo at - `.github/workflows/seidroid-xreview.yml` (an `issue_comment` workflow only fires from the - default branch, so the thin caller must live in each reviewed repo); it wires the trigger - and `uses:` the reusable workflow at a pinned ref. - -## How a run works - -1. A trusted commenter writes `seidroid xreview` on a PR. -2. 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. The reusable workflow's `xreview` job runs on the `uci-default` org ARC scale set, - in-cluster. 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.
