Migrate an API import by import
Sweep a codebase from a legacy API to its v2 replacement with tests and typecheck as the safety net, capped at 30 turns.
/goal every file importing from `./legacy-api` now imports from `./v2-api`, all tests pass, and `npm run typecheck` is clean — stop after 30 turns

Implementation note
Swap the module paths for your own migration. The typecheck condition catches signature drift that tests miss.

Refactor auth module, pass tests
Refactor the authentication module iteratively until all tests pass, stopping after ten attempts.

Dead code elimination
Hunt down unreferenced exports, unused files, and unreachable branches, deleting them in small verified steps until the analyzer reports clean.
/goal `npx knip` reports no unused files or exports — remove one cluster of dead code at a time, run the full test suite and typecheck after each removal, and revert any deletion that breaks them; stop after 15 turns

Repair React issues in small batches
Baseline the scan, fix a small batch of real errors or warnings, and verify each change improves it without regressions.
Run `pnpm exec react-doctor . --verbose --yes --offline --fail-on none` to record the baseline, then rerun with `--fail-on error`. Fix at most five genuine findings, run the same scan and relevant project checks, and keep only verified improvements. Clear errors before high-confidence warnings. Stop when clean, blocked, approval is required, a finding is false-positive, or another pass makes no measurable progress. Finish with baseline and final results, retained fixes, reverted attempts, checks, and remaining findings.
