What problem does it solve?
Helps authors design, evaluate, and iteratively improve Claude-style SKILL.md skills so they trigger reliably and produce higher-quality, repeatable outputs. It removes manual trial-and-error by providing an opinionated loop for drafting SKILL.md, generating test prompts, running comparative runs (with and without the skill), and surfacing quantitative and qualitative feedback.
Core Features & Use Cases
- Iterative skill development: Draft SKILL.md content, generate test prompts, run evals, grade outputs, and rewrite the skill based on feedback.
- Benchmarking & analysis: Aggregate grading results, produce benchmark summaries, and surface variance and pass-rate diagnostics.
- Tooling & packaging: Includes scripts to run eval loops, generate an HTML review viewer, aggregate benchmarks, improve descriptions, and package a skill into a distributable file.
- Use Case: Create a new automation skill, run blind comparisons against a baseline, collect user reviews via the viewer, and apply suggested revisions until the pass rates stabilize.
Quick Start
Ask the skill-creator to draft a SKILL.md for your task, produce 2–3 realistic test prompts, run evals, and return the benchmark and suggested SKILL.md edits.
