This skill helps users create new Claude skills and iteratively improve existing ones through a structured test-and-review process. According to SKILL.md, it guides drafting a SKILL.md file based on an interview about intended behavior and triggering conditions, then generates test prompts that are run via subagents to compare skill-assisted output against a baseline. Outputs are graded against defined assertions and aggregated into benchmark data covering pass rate, execution time, and token usage. A review viewer is launched so the user can inspect results and leave feedback, which feeds back into further revisions. The skill also includes a separate procedure for optimizing a skill's description to improve triggering accuracy, and it adapts its steps depending on whether it is running in Claude Code, Claude.ai, or Cowork.
