Precommit

Workflow

1. Read package.json to identify available scripts
2. Format + lint fix: run npm run lint-fix or npm run lint:fix (whichever exists)
3. Lint + types: run npm run lint (runs tsc --noEmit + eslint)
4. Tests: run npm test
5. Report overall PASS or FAIL with file:line error references

Rules

• Always auto-fix before reporting errors
• Run lint-fix → lint check → test sequentially
• If lint-fix fails, still run lint check and tests; report all failures at the end
• Report errors as file:line references
• Never commit, stage, or push anything

Error Handling

• If no package.json → report and stop
• If neither lint-fix nor lint:fix script exists → skip fix, still run lint
• If lint script missing → skip lint entirely, note it was skipped
• If test script missing → skip tests, note it was skipped
• If all scripts missing → report nothing to run, stop
• If tests time out → report and suggest increasing --testTimeout in runner config
• If runner crashes (exit code other than 0 or 1) → report crash output and stop
