The action therefore expands a leading Markdown command before invoking OpenCode and applies the effective agent as `default_agent`. +The bundled `/review-pr` command submits a GitHub pull request review through `gh api`. It uses inline review comments for every finding that can be safely anchored to the PR diff, and includes only unanchorable findings in the review body as summary-only fallback items when at least one inline comment is submitted. If no finding can be anchored inline, `/review-pr` returns a top-level markdown fallback instead. When there are no summary-only findings, the review body is a single line (`OpenCode PR Review: inline finding(s).`) with no empty "Summary-only findings" section. -Command lookup uses this precedence: +A successful structured review run produces one GitHub review summary (with its inline comments), which `/review-pr` updates in place with the run link. `/review-pr` never calls `gh pr comment` or the issue comment API itself. It may still return a short final assistant message after submitting the review; `opencode github run` posts that as a separate top-level completion comment, so a run can produce the review plus at most one additional completion comment — not necessarily exactly one top-level artifact. -1. the checked-out repository's `.opencode/commands/`; -2. the user's installed `~/.config/opencode/commands/`; -3. the action's bundled commands as a fallback when `enable-toolkit: true`. +The bundled toolkit ships an `external_directory` permission in `.opencode/opencode.jsonc` (copied into `~/.config/opencode/` with the rest of the toolkit) that denies by default, so a stray attempt to read outside the checked-out repository, such as inspecting `/opt/pipx/logs/*` after a failed tool install, is denied immediately instead of blocking on the default "ask" prompt, which nothing can answer in a non-interactive GitHub Actions run and would otherwise hang until `timeout-minutes` kills it. The one narrow exception is `~/.config/opencode/scripts/resolve-app-token.sh` itself: `/review-pr` sources that bundled script from outside the checked-out repository to resolve the OpenCode App token, so it is individually allow-listed ahead of the catch-all deny rule; no other external path is permitted. -A command's frontmatter `agent:` overrides the action input only when it selects a primary agent. `$ARGUMENTS` is expanded literally. Commands using `model:`, `subtask:`, positional placeholders, shell template blocks, or config-defined command entries are rejected or left to native OpenCode handling rather than partially emulated. +### Review author and the OpenCode App token -## Pull Request Reviews +When the default OpenCode GitHub App flow is used (`use-github-token: false`), `/review-pr` resolves every _candidate_ App token from git credential configuration (checking the local `http.https://github.com/.extraheader` key, `git config --get-urlmatch`, and `--get-regexp`/`--show-origin --get-regexp` across all config scopes to also cover includeIf/global-style credential files, matching only keys whose URL host is exactly `github.com`). None of these candidates is trusted on format alone: an `actions/checkout`-persisted `GITHUB_TOKEN` credential or a PAT can be written to the exact same git-config key in the exact same `x-access-token:` basic-auth shape as the real OpenCode App token, and a workflow can legitimately have both that checkout-persisted credential at the highest-priority key and a real OpenCode App token from a lower-priority source. So before any structured review write, `/review-pr` tries each candidate in order, verifying it by creating a throwaway pending PR review with it, checking the `user.login` on the response, and immediately deleting that pending review regardless of the outcome. The search stops at, and exports, the first candidate that verifies as `opencode-agent[bot]`; an earlier unverified candidate does not stop it from trying later ones. Every structured review submission, review-body update, and anchor-validation retry re-resolves and re-verifies immediately beforehand. -The bundled `/review-pr` command pins the PR head SHA before analyzing the diff and refuses to publish a conclusion if the head moves. Structured inline reviews are submitted through a helper that: +**Limitation:** GitHub does not expose a read-only "whoami" endpoint for GitHub App installation tokens — `GET /user` requires user-to-server auth and returns 403 for every installation token alike, so it cannot distinguish the OpenCode App token from the workflow's own `GITHUB_TOKEN` or a PAT-backed credential. The pending-review probe above is the safest available alternative: a pending review is never visible to anyone but its own author until submitted, so a failed or mismatched check never publishes anything to the PR, but creating and deleting the probe are still real API writes, not a true read-only check. -- derives the repository and PR number from the GitHub Actions context; -- accepts only `commit_id`, `body`, and a non-empty comments array with line-based anchors; -- injects `event: COMMENT`; -- verifies the review-author token; -- rechecks the live PR head immediately before the review POST. +**If no App token can be verified as `opencode-agent[bot]` while `use-github-token` is `false`, `/review-pr` fails the run instead of submitting the review.** It never silently falls back to the workflow's `GH_TOKEN`/`GITHUB_TOKEN`, or to an unverified candidate, for a structured review submission, because either could make the review appear under the wrong identity instead of `opencode-agent[bot]`. -The command does not retarget findings to a newer commit and does not update the submitted review body after posting. +If the workflow explicitly opts into `use-github-token: true` and no candidate App token verifies, this is intentional: `/review-pr` falls back to the workflow's `GH_TOKEN`/`GITHUB_TOKEN`, and direct review submissions are expected to appear as `github-actions[bot]` in that case. A verified `opencode-agent[bot]` candidate still takes precedence over that fallback when one is found — see the exact precedence rules below. -### Review author and the OpenCode App token +**Exact credential precedence for every structured review write, regardless of `use-github-token`:** + +1. Every resolved candidate App token is tried in order; the first one that verifies as `opencode-agent[bot]` always wins, is exported, and is used for that write. This applies even when `use-github-token: true`, so a real App token still takes precedence over the explicit workflow token when one is available and verifies. +2. Only when **no** candidate verifies does `use-github-token` decide the outcome: `true` falls back to the caller's original `GH_TOKEN`/`GITHUB_TOKEN`, unmodified; `false` fails the run. -When the default OpenCode GitHub App flow is used (`use-github-token: false`), `/review-pr` resolves candidate App tokens from git credential configuration and verifies the author identity with a throwaway pending review before the structured write. If none verifies as `opencode-agent[bot]`, the review fails instead of silently using another identity. With `use-github-token: true`, the workflow token is an explicit fallback. +That fallback is safe because the best-effort read helper (`opencode_prepare_gh_token`, used for `gh pr view`/`gh pr diff`) is a no-op whenever `use-github-token: true` — it never exports an unverified git-config candidate over the caller's own token, so there is nothing to overwrite the explicit workflow token with before the write gate runs.
