What problem does it solve?
Removes the friction and guesswork from authoring, testing, and improving AI Skill files by providing a repeatable, script-driven workflow for drafting SKILL.md, running trigger and behavior evaluations, and iterating descriptions and implementations until the Skill reliably triggers and performs.
Core Features & Use Cases
- Guided skill authoring: Templates and guidance for writing SKILL.md frontmatter and body so descriptions trigger correctly.
- Eval orchestration: Scripts to run trigger evaluations, spawn with-skill and baseline runs, grade outputs, aggregate benchmarks, and generate review pages.
- Analysis & iteration: Tools and agent guidance for drafting assertions, interpreting results, and improving skill text and bundled scripts.
- Packaging & presentation: Utilities to package skills into distributable .skill files and to produce standalone HTML review reports for human feedback.
- Use Case: A developer drafts a new skill, generates 3 realistic test prompts, runs the evaluation loop, inspects the review page, and iterates the SKILL.md and scripts until pass rates and benchmarks meet acceptance criteria.
Quick Start
Ask the assistant to draft a SKILL.md for a new capability, produce 2–3 realistic test prompts saved to evals/evals.json, and run the evaluation loop to generate a benchmark.json and review HTML.
