What problem does it solve?
Reduces the friction of designing, evaluating, and iterating on Claude Code skill modules by bundling best-practice workflows, test harnesses, grading, and benchmarking into a single reproducible workflow.
Core Features & Use Cases
- Skill drafting: Guided process for capturing intent, writing SKILL.md frontmatter and body, and organizing bundled resources.
- Evaluation & benchmarking: Spawn parallel with-skill and baseline runs, draft assertions, grade outputs, aggregate metrics, and surface pass-rate, time, and token deltas.
- Iteration & optimization: Improve skill prompts and descriptions automatically, run held-out trigger tests, and package validated skills for distribution.
- Use case: A developer wants to turn a manual prompt into a production-ready skill: draft SKILL.md, generate 3 realistic eval prompts, run comparisons, review outputs in the viewer, then iterate until benchmarks and human feedback are satisfactory.
Quick Start
Use the skill-creator to draft a new SKILL.md, produce 2–3 realistic test prompts, run the eval loop, and summarize the benchmark results for the first iteration.
