What problem does it solve?
Reduces the friction of designing, testing, and iterating Claude skills by providing a reproducible workflow for drafting SKILL.md files, generating test prompts, running trigger and baseline evaluations, grading outputs, and producing human-readable benchmark reports.
Core Features & Use Cases
- Skill authoring: Guided process for drafting SKILL.md frontmatter and detailed instructions to make skills discoverable and reliable.
- Eval & benchmarking: Orchestrates trigger evaluations, baseline comparisons, grading, aggregation into benchmark.json, and HTML review viewers for human feedback.
- Iteration & optimization: Automates iterative improvement loops including description optimization, blind comparisons, analyzer suggestions, and packaging into distributable .skill files.
- Use Case: A developer or QA engineer creating a new skill can draft the skill, create representative evals, run parallel with/without-skill tests, review outputs in the generated viewer, and apply improvements until passing criteria are met.
Quick Start
Use the skill-creator to draft a SKILL.md for a new skill, create 2–3 realistic eval prompts, run one iteration of the eval loop, and open the generated review HTML to inspect grading and benchmark results.
