implementlisted

Implement the work described by the user in the spec or tickets. For non-trivial implementation work, load and follow the `moh-implementation-flow` companion skill before exploration. Use /tdd where possible, at pre-agreed seams. 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. Commit your work to the current branch.
