v1.0Saved Jun 18, 2026

Implement the work described by the user in the PRD or issues.

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 /review to review the work.

Commit your work to the current branch.

Summary

A skill that guides an agent to implement work described in PRDs or issues using TDD practices, with regular typechecking and testing. The skill delegates to other skills (/tdd, /review) and assumes the agent will commit completed work to the current branch.

Risk Signals

WARNING

No explicit scope boundaries documented — skill does not define what 'work' means or what files the agent should modify

SKILL.md (overall)
WARNING

Delegation to /tdd and /review skills without documenting their expected behavior or outputs — agent must infer coordination

SKILL.md, line 5-6
WARNING

Git commit instruction ('Commit your work to the current branch') lacks guardrails — no documentation of what should/shouldn't be committed, no dry-run or validation step

SKILL.md, line 9
WARNING

No error handling guidance for failed tests, type errors, or merge conflicts during commit

Use Cases

  • Implement features from a PRD with test-driven development
  • Convert issue descriptions into working code with automated testing
  • Build features while maintaining code quality through regular type checking
  • Complete a feature branch with comprehensive test coverage before review

Quality Notes

  • Skill is extremely brief and lacks operational detail — leaves critical implementation decisions to the agent's inference
  • References external skills (/tdd, /review) without defining their contract or expected outputs
  • No edge cases addressed (e.g., what if tests fail? what if typechecking fails? what if commit fails?)
  • Does not define what 'work' means or what constitutes 'done' — success criteria are implicit
  • Assumes agent knows how to run 'typechecking' and 'full test suite' without specifying commands or tools
  • Git commit step has no safeguards — no mention of commit message format, branch validation, or pre-commit checks
