Implement

Deliver the requested change through the native Fallow lifecycle.

1. Read AGENTS.md, docs/README.md, and docs/development/task-context-map.md.
2. Inspect the live branch, worktree, open pull requests, and origin/main.
3. Write the acceptance criteria and verification plan to the gitignored .plans/<task>.md.
4. Resolve open decisions before editing. Sort each open question:
   • fact: the code, docs or history hold the answer; look it up;
   • observable: a run shows the answer; probe a fresh build on a public fixture with --format json --quiet;
   • decision: scope, naming, contract or trade-off; ask the maintainer in one round, with a recommended answer for each question. Record the answers in the plan. Skip this step when no decision is open.
5. For changes with user-facing design decisions, run panel-review before editing.
6. Create an implementation branch and ready pull request before tracked edits.
7. Implement in pipeline order and keep generated contracts, public docs, and companion repositories synchronized. Follow the test evidence rules in docs/development/quality-gates.md. For a bug, get a command that fails before you change code; after a restart, suspect the .fallow/ cache first.
8. Run every applicable gate from docs/development/quality-gates.md.
9. Run the reviewer set selected by docs/development/review-routing.md. Resolve every block.
10. Update the pull request with current verification evidence and the proof level of each claim.

Preserve unrelated work. Never create process artifacts under committed docs/. Prefer durable knowledge in indexed docs and keep this skill procedural.
