implement

Implement the work described by the user in the spec or tickets.

Prefer one ticket per session; clear context between tickets.

Use the /tdd skill where possible, at pre-agreed seams.

Run typechecking regularly, single test files regularly, and the full test suite once at the end.

Do not commit. After the slice is done, run /code-review in a fresh turn (or ask for it explicitly).

For a whole attached plan with council / best-practices / YAGNI, use /implement-plan instead.
