implement

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

Investigate the code first. Then load /tdd and use it where it adds value, at seams agreed with the user. Do not force a TDD cycle for trivial behavior, but still write tests when they provide useful coverage.

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

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

After the review, load /commit and follow its instructions to commit the changes.
