Implement

Establish the requested outcome, constraints, and acceptance checks before editing. Inspect the relevant contracts, callers, and existing conventions; make the smallest coherent change.

Work in an isolated branch or worktree when parallel work or a risky change warrants it. Do not claim a delegated task or command ran without its result. Keep progress reports factual and concise.

Run the narrowest meaningful checks first, then the project-required checks. Review the completed diff for correctness, error paths, compatibility, security/privacy, tests, and unnecessary complexity. Use independent reviewers only for distinct expertise; consolidate duplicates and fix confirmed issues.

Stop and ask the user when requirements conflict, a destructive/external action needs approval, or evidence cannot resolve a material design choice. Finish with changed files, verification, residual risk, and any decisions still owned by the user. Preserve project-local state only when it is explicitly required; do not invent a persistent memory format.
