[code-infra] Add Renovate PR report workflow by brijeshb42 · Pull Request #1793 · mui/mui-public

brijeshb42 · 2026-08-18T04:40:47Z

Summary

Add a manually triggered Renovate PR report that fans out over every repo the Renovate App is installed on (discovered dynamically from the App installation; scheduling to be enabled after merge).
Analyze release notes with a configurable Claude model, defaulting to Haiku. Heuristics (bump level, breaking-change keywords, security advisories, pre-release targets, missing changelogs) still produce a report when the model is unavailable.
Diagnose failing CI: for PRs with red checks — GitHub Actions or CircleCI — the failing jobs' log tails are fetched and the model names the dependency that likely broke CI and the fix direction (or calls the failure unrelated: flaky test, infra). Any log that cannot be fetched degrades to a stub, never failing the report.
Each analyzed PR gets its risk verdict as a sticky comment, edited in place on later runs. The comment's last line embeds the verdict keyed by head SHA, which doubles as the cache. @mui/infra is mentioned when a PR needs attention; when a later run reports a materially different issue (breaking status, security flag, culprit dependency, or CI culprit — not reason wording), the comment is recreated so the mention pings again.

Example of the sticky comment on a PR:

### Renovate update risk

**major bump** — possibly breaking — supports-color: Requires Node.js 18 or newer.

**CI failing** — supports-color: Update the color detection call in scripts/build.mjs.

@mui/infra — this update needs a look.

Test plan

pnpm test --run renovatePrReport
pnpm test --run
pnpm release:build
pnpm typescript

The aggregate report below is written to the action run's job summary only (it is not posted as a comment anywhere) —

Will circleci diagnosis work for private repos?
Does this run the whole matrix using the mui-public federation rule? That would mean it eats in our budget even though it does work on other repositories.
When will this be triggered?

- Replace the GraphQL viewer lookup, which fails for installation tokens, with an explicit comment-author input; the fleet workflow derives it from the App slug and the reusable workflow defaults to github-actions[bot]. - Match report comment authors exactly instead of stripping the [bot] suffix, so a same-named user account cannot forge the sticky state. - Let the report degrade to heuristics when the Claude step fails. - Share the state-comment serializer between renderer and parser, and cover the announce flow with round-trip tests.
