Code Quality (Biome)

Analyze → fix → test, drivable by the goal-plugin's judge loop. The skill is the HOW; the goal is the WHEN-TO-STOP (judge reads one exit code).

Pick the mode

flowchart TD
    Q{Driving a goal /<br/>cleaning your own work?}
    Q -->|default| C[CHANGED-FILES MODE<br/>goal loop · git diff vs develop<br/>surgical, low blast radius]
    Q -->|explicit cleanup| W[WHOLE-REPO MODE<br/>human-gated · one package,<br/>one rule-group per turn]
    C --> CC[npm run quality:changed]
    W --> WW["biome lint &lt;pkg&gt; --only=&lt;group&gt;"]

When unsure, use changed-files mode. Never turn whole-repo autofix loose inside a goal loop.

The oracle (what the judge reads)

One command, one exit code:

npm run quality:changed
# = biome check --changed --error-on-warnings --write  (safe-fix the diff)
#   && tsc --noEmit                                     (type gate)
#   && npm test                                         (test gate)

• exit 0 → Biome clean (warn+error) on changed files, types compile, tests green → goal achieved.
• non-zero → fix the reported issues, run again. The judge says continue.

--changed compares the committed branch state against develop (the repo's integration branch, set as vcs.defaultBranch in biome.json). Uncommitted or untracked files are NOT scoped by --changed — commit your work first, or pass an explicit path.

Procedure (every turn)

1. ANALYZE
   npm run quality:changed        # or: biome lint . --reporter=json (whole-repo)
   Read the JSON. Group issues: safe-fixable vs unsafe vs manual.

2. FIX  (surgical — only files in the diff)
   - Safe fixes are already applied by `--write`. Confirm they're sane.
   - Type errors + unsafe-rule + manual issues: edit by hand, minimally.
   - DO NOT run `--unsafe` in the loop. Surface unsafe fixes as a report.
   - DO NOT touch files outside the diff (AGENTS.md surgical rule).

3. TEST  (the gate)
   tsc --noEmit && npm test
   - Red? REVERT this fix batch. Never stack broken autofixes.
   - Green + 0 issues on scope? Done. Else loop.
