dan-claude-bot 884a95f5fa feat: label automation — the state reconciler, path-scoped labeler, and CONTRIBUTING
The machinery LABELS.md promised. labels.yml runs the reconciler on a
15-minute cron plus PR events (pull_request_target — every PR here is from a
fork, where pull_request gets a read-only token; no PR code is ever checked
out). The script derives each open PR's state:* from GitHub's own facts and
converges labels statelessly; stale is judged from real activity (commits,
comments, reviews), never label churn, so the sweep cannot un-stale its own
mark. actions/labeler applies scope:* from changed paths. CONTRIBUTING.md is
the guideline: the PR loop, and who sets which labels. Rehearsed with
DRY_RUN=1 against the live repo; shellcheck-clean.

How change lands in this repo. The short version: PRs are born as drafts, three reviewer bots take the first rounds, a human takes the last word — and labels tell you where everything is without opening anything.

The PR loop

  1. Fork and branch. Contributors work from forks; upstream branches are for maintainers. Title the PR conventionally (feat:, fix:, docs:).
  2. Open as a draft while you build. Drafts are invisible to the reviewer bots on purpose.
  3. When it's ready: mark ready-for-review and request all three bots — claude-bot-andresmgsl, codex-bot-andresmgsl, grok-bot-andresmgsl. They poll roughly every 15 minutes.
  4. Rounds are answered whole. Wait until all three have reviewed, then answer the entire round in a single reply, push the fixes, and re-request the bots that didn't approve. Prefer verification over argument: a test settles what a comment thread can't.
  5. When all three approve, the final review goes to the maintainer — the labels workflow requests it automatically.
  6. Checks must be green: npm run check, npm run build, and npm test locally mirror what CI runs.

Labels — who sets what

The full taxonomy lives in LABELS.md. What matters day to day is who sets each kind — most of it is machinery, and hand-moving a machine-owned label just gets corrected on the next pass:

Labels Set by
state:* the labels workflow (.github/workflows/labels.yml) — recomputed from GitHub's own facts every 15 minutes and on PR events. Never by hand.
stale the same workflow — 48h without commits, comments, or reviews. blocked PRs are exempt: they are quiet legitimately.
scope:* on PRs actions/labeler, from the changed paths (.github/labeler.yml). Additive — you may add more, the machine won't remove them.
scope:* on issues you, when opening or triaging — issues have no paths to derive from.
blocked, release you — automation never guesses intent.
bug / enhancement / documentation you, on issues only — a PR's type already lives in its title.

Issues

Give issues the same care as PR titles: say the surface in the title, apply a scope: label and a type label (bug / enhancement / documentation) when you open one, and blocked when it waits on something — that is what keeps the board navigable as the issue count grows.
