What implement does

This skill implements work described in a specification or set of tickets in the current project. When the user supplies a ticket reference, it fetches the ticket from the issue tracker and states its title before work begins. An ambiguous reference prompts a clarification.

At agreed seams, the skill calls tdd where possible. It runs typechecking and individual test files regularly, then runs the full test suite at the end. After implementation, it calls code-review and commits the work to the current branch.

Install it for tasks that should include tests, review, and a commit rather than stop at a code change. For a one-off question with no repository changes, this skill is excessive.

What it helps with

  • implement work from a specification
  • fetch a referenced issue ticket
  • run typechecking during implementation
  • review changes with code-review
  • commit completed work to the current branch

Example prompts for the agent

  • Implement the work described in this spec.
  • Fetch this ticket and complete the work.
  • Make the changes, run the tests, and commit the result.

Call the Skill tool with "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, call the Skill tool with "code-review" to review the work.

Commit your work to the current branch.
