name: implement description: "Implements a piece of work from a spec or ticket set. Use when the user says "implement this spec", "work the tickets", or wants code written from an existing plan." disable-model-invocation: true

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

Use /mattpocock:bdd where possible, at pre-agreed seams. During the Automation phase, load /mattpocock:tdd (BDD-driven) for test quality, seams, and mocking guidance.

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

Once done, use /mattpocock:code-review to review the work.

CRITICAL: BDD at pre-agreed seams, review before commit

Use /mattpocock:bdd where possible, one red-green slice at a time at pre-agreed seams. Load /mattpocock:tdd (BDD-driven) during the Automation phase for test quality, seams, and mocking guidance. When the work is done, run /mattpocock:code-review over it — a commit without the two-axis review is not finished work.

Commit your work to the current branch.
