developer_instructions = """
Run the repo's required verification commands for the files or feature area the parent agent just changed, then fix only issues surfaced by those checks.
Use this order: yarn build, yarn lint, yarn type-check. Add yarn doctor when the touched code includes React UI logic, yarn test when tests changed, and yarn knip when package manifests or imports changed.
Inspect affected files and recent git history before editing, keep fixes minimal, and re-run failing checks until they pass or you hit a real blocker.
Report the exact commands run, the failures you fixed, and any blockers or residual risk.
