Two failures from the same afternoon, both in the bot workflow. The review of #6272 ran for 34 minutes across four subagents and posted "No issues found. Checked for bugs and CLAUDE.md compliance." — three lines for a 73-file diff. The agent had written a per-area coverage summary in its own last turn and then dropped it on the floor, because the code-review skill's comment template carries findings and nothing else. A comment that cannot distinguish a thorough clean review from a run that died early is not evidence, so REVIEW.md now states what the posted comment must show and the system prompt points the run at it. The same run logged 67 permission denials. Only the inline-comment MCP tool was named in --allowedTools, so `gh api`, writing the diff to a scratch file, and reading it back were all auto-denied: agents spent turns hunting for a writable directory, and the openapi.json copy check REVIEW.md calls blocking could not be run at all ("gh api was unavailable in this sandbox"). Name the tools the review actually uses. The conflict resolution on #6243 resolved both conflicted files correctly and was then rejected by its own guard: "Edits outside the conflicted set: CLAUDE.md". The agent never touched CLAUDE.md — it had Edit rights on exactly two paths and no shell. claude-code-action deletes and restores CLAUDE.md, .claude/, .mcp.json and friends from the base branch before it runs, because the PR head is untrusted, and that restore is what dirtied the tree. Name that set once, exclude it from the stray-edit check, and hand back rather than resolve when a conflict lands inside it — the restore would silently overwrite the resolution and stage the base copy.

Review instructions
3x-ui is a Go (Gin + GORM) web panel that generates configuration, share links and subscriptions for other programs — Xray-core, mihomo, sing-box, mtg-multi — and is deployed by operators who upgrade in place. Judge findings by what breaks for those consumers and operators, not by style.
What a blocking finding means here
Reserve blocking severity for:
- Security on the exposed surfaces:
internal/web/controller/, session and middleware code, the PUBLICinternal/sub/subscription server, and Xray config generation ininternal/xray/. - A state-changing inbound or client operation that bypasses
runtime.Runtime(internal/web/runtime/) and callsinternal/xray/api.godirectly, or dispatches from a controller or cron job. It passes every local test and silently breaks every multi-node deployment. - A schema or model change without a matching hand-written migration in
internal/database/db.go, one that behaves differently on SQLite and PostgreSQL, or one that loses or overwrites operator data on upgrade or rollback. There are no migration files and no down-migrations. - A change to what the panel emits on the wire — Xray config JSON, share
links, subscription/Clash YAML, mtg-multi TOML — that a downstream client
would reject or read differently, or that makes the three independent link
implementations (Go
internal/util/link/+internal/sub/, TSfrontend/src/lib/xray/, TSdocs/lib/xray/) diverge from one another. - Any edit to
.github/workflows/: this repository runs workflows with secrets against a public fork stream. Untrusted expression interpolation intorun:blocks, broadened permissions, weakened guards, or a job that executes pull-request code is blocking.
Style, naming and refactoring suggestions are nits at most.
Always check
- A new
g.POST/g.GETininternal/web/controller/needs the whole chain: an entry infrontend/src/pages/api-docs/endpoints.ts, regenerated artefacts (make gen), any new API-boundary struct added toStructAllowintools/openapigen/main.go, andfrontend/public/openapi.jsoncopied todocs/public/openapi.jsonwith the docs MDX regenerated (cd docs && pnpm gen:api). CI checks the first three; the docs copy is checked by nothing — a missed copy is blocking, not a nit. - A new i18n key exists in ALL 13 locale files in
internal/web/translation/and is referenced fromfrontend/srcor Go in the same PR. - A bug fix carries a test that would fail without the fix. A test that
passes either way, asserts only
err != nilorlen(x) > 0, or was made green by regenerating golden fixtures or Vitest snapshots is a real finding.
Do not report
- Anything CI already enforces: golangci-lint and gofumpt, oxlint, format
and typecheck,
npm audit, govulncheck. - The contents of generated files (
frontend/src/generated/,frontend/public/openapi.json,docs/public/openapi.json) or lock files. Those files being STALE after a source change is reportable; their style is not. - Missing tests for getters, constants, renames or pure map lookups —
CLAUDE.mdrejects such tests outright.
Verification bar
- A claim about behaviour needs a
file:linecitation from this repository, not an inference from a name. - A claim that a downstream client rejects or requires a wire-format detail — a config key, JSON tag, URI query parameter, YAML or TOML key, an encoding or hash choice — must name the upstream symbol that decides it (repository, file, identifier). If you cannot verify it, keep the finding but say explicitly that it is unverified instead of asserting it.
Cap the nits
Report at most five nits per review and say "plus N similar" in the summary for the rest. Lead the summary with "No blocking issues" when everything found is a nit. After the first review of a PR, report blocking findings only.
What the comment must show
The posted comment is the only part of a review anyone sees, so a bare "no issues found" is a receipt, not a review: nothing in it says whether the diff was read or the run died early. Every comment therefore ends with a short coverage list — one line per area actually checked, naming what was examined and what it turned out to be, plus the head SHA and the size of the diff it covers. Say which claims could not be verified and why, including a check this environment blocked. Keep it under ten lines; it is evidence, not a retelling of the pull request.
