The workflow file must exist and have identical +content to the version on the repository's default branch. +``` + +It is a reasonable guard on Anthropic's own credentials — a PR should not mint +an app token for a workflow nobody has merged — but it applies to the *token +exchange*, not to reviewing. The effect was that the PR adopting this workflow +could never be reviewed by it: the action skipped, the step went green in about +four seconds, and the gate below fails closed on empty output, so every +migration PR in every repo showed a red `Automatic PR review`. + +Passing `github_token: ${{ github.token }}` makes `setupGitHubToken` return +early, so the exchange never happens. GitHub has already scoped that token to +the job's `permissions:` block, which is where the equivalent restriction +belongs. The costs: comments come from `github-actions[bot]` rather than the +Claude app, and on a `pull_request` from a fork `GITHUB_TOKEN` is read-only, so +posting would fail — `require-write-access` skips those anyway, leaving only a +write-access author working from a fork as the real gap. + +Whether a failed job blocks a merge is branch protection, set per repo. That is +the reversible half of the decision, and adopting this workflow does not make it +for you. There is deliberately no override label: bypassing a red check is +something branch protection already gates on permission and records against a +person. (`skip-label` is the exception, and it skips the whole review rather +than a finding — restrict who can apply it.) + +Worth knowing before marking `Automatic PR review` required: **a skipped job +satisfies a required status check.** So every path that skips the review — the +label, a non-member author, the write-access gate failing — reports green, and +the check says "reviewed" about a PR nobody reviewed. The first two are the +intended behaviour. The third was not, so a failed `check-member` now starts the +review job and fails it in its first step instead of leaving it to skip; that +costs a runner start and no API tokens. `check-member` answers `'false'` on a +permission lookup it cannot make, so reaching that step means the job itself +died — runner or action infrastructure, and a re-run. + +The severity rubric that assigns those levels is `review/rubric.md`, here rather +than in each repo, because the gate and the schema are here: three copies of the +rubric would drift from the thing scoring them. The workflow appends it to the +caller's `prompt-file`, so a repo's own file should say what to look for in +*its* code and leave grading alone. A repo migrating a prompt that already +carries a rubric — `truenas/api-client-ts` does — should delete that half. + +`tooling-ref` exists because the schema, rubric and scripts have to be checked +out into the caller's workspace at run time, and a reusable workflow cannot see +which ref it was itself called at. (`github.job_workflow_sha` is exactly that, +but actionlint 1.7.7 does not know the property and fails the file, and this +repo's CI runs actionlint.) It defaults to `master`, which matches every current +caller. A caller pinning this workflow to a tag must pin `tooling-ref` to the +same tag, or it gets `master`'s tooling against a pinned workflow. + +Everything the run generates, and the tooling checkout itself, goes in +`.claude-review/` in the workspace, added to `.git/info/exclude` so it stays out +of `git status` and out of the review. + ## Actions ### `.github/actions/prepare` @@ -137,15 +313,35 @@ which had drifted to a floating `'24'` against the others' pinned `24.13.1`. ## Adoption status -| Repo | `check-ticket` | `check-member` | `prepare` | -|---|---|---|---| -| `truenas/webui` | adopted | migrating (`main.yml`) | migrating | -| `iXsystems/truenas-ui-components` | adopted | n/a — no self-hosted runner | migrating | -| `truenas-connect/ui` | adopted | migrating (`main.yaml`) | migrating | - -**Automatic PR review is deliberately not here yet.** Each repo keeps its own -`claude.yml` while that work is in flight; revisit sharing it once those changes -have settled. +| Repo | `check-ticket` | `pr-title` | `check-member` | `prepare` | review | +|---|---|---|---|---|---| +| `truenas/webui` | adopted | n/a — no semantic-release | migrating (`main.yml`) | migrating | own `claude.yml` | +| `iXsystems/truenas-ui-components` | adopted | migrating | n/a — no self-hosted runner | migrating | migrating (#175) | +| `truenas-connect/ui` | adopted | n/a — no semantic-release | migrating (`main.yaml`) | migrating | migrating (#370) | +| `truenas/api-client-ts` | migrating | migrating | via the review | migrating | migrating (#33) | +| `iXsystems/ux-github-workflows` (this repo) | adopted (`pr-ticket.yml`) | n/a — no semantic-release | self-test in `ci.yml` | n/a | n/a | + +This repo calls two of its own workflows, by relative path rather than +`@master`, so a change to either is executed on the pull request that makes it +instead of on a consumer's next one: `pr-ticket.yml` runs `check-ticket.yml`, +and `ci.yml`'s `self-test` job runs `check-member.yml`. `pr-ticket.yml` is a +separate file from `ci.yml` because the ticket check needs the `edited` trigger +and the rest of CI does not want it. + +`api-client-ts` is the repo the review came from.

The table says +> the release type is `minor`, which this change makes untrue. + +That applies to inline comments and to the top-level comment alike. A reader +should be able to tell a BLOCKER from a LOW without inferring it from how +strongly the sentence is worded, and without cross-referencing the CI +annotations to find out. + +Two things follow from it: + +- **Say the level even when it is LOW.** An unlabelled finding reads as more + serious than a labelled LOW, which is the opposite of what you want. +- **The label and the structured output must agree.** They are the same + judgement written twice, and the gate keys off one of them. If you find + yourself wanting to write a different level in the prose, the rubric decides + and both change together. + +## The opening line must agree with the findings under it + +**The check fails on any finding at MEDIUM or above.** So whether the set is +blocking is not a matter of tone — it is decided, and you already decided it +when you assigned the severities. + +Open with the count by level, and nothing softer: + +> Three findings: one MEDIUM, two LOW. + +Do not write "none blocking", "all minor", "nothing serious" or "non-blocking" +over a set containing a MEDIUM, HIGH or BLOCKER. That sentence is a claim about +the gate, it is checkable, and it will be checked — a summary saying nothing +blocks above a red check tells the reader the check is broken when it is +working exactly as specified. + +The reverse matters too. Do not hedge a genuinely clean review into sounding +qualified: if there are no findings, or only LOW ones, say so plainly, because +that is the result that lets someone merge. + +## Machine-readable summary + +Return your findings as structured output matching the JSON schema this run was +started with — severity, file, line, and a one-line summary with no markdown. +The severity enum is enforced by the schema, so it can only be one of the four +above. + +Include every finding, LOW ones too. An empty array is valid and expected on a +clean change; it is not a sign the review failed. + +The structured output is what tooling reads and the comment is what a human +reads, so they differ in form — prose and reasoning there, one flat line here. +They must not differ in content: every finding appears in both, at the same +severity. A finding that only appears in the comment does not reach the gate. diff --git a/review/schema.json b/review/schema.json new file mode 100644 index 0000000..37dbdeb --- /dev/null +++ b/review/schema.json @@ -0,0 +1,39 @@ +{ + "$schema": "http://json-schema.org/draft-07/schema#", + "title": "Claude review findings", + "description": "Structured result of the automated PR review.
