Implement the work described by the user in the spec or tickets.
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, spawn one read-only subagent with the ticket context to run /open-code-review-delegate. Validate and fix its findings, rerun affected tests.
Use /to-commit to commit your work to the current branch.
