What problem does it solve? Building a reliable skill requires more than writing instructions — you need test cases, baseline comparisons, quantitative benchmarks, and description tuning so the skill actually triggers when it should. This Skill guides the full lifecycle from draft to validated, optimized skill. ## Core Features & Use Cases - Skill Authoring: Interview-driven drafting of SKILL.md files with proper frontmatter, progressive disclosure structure, and writing-style guidance. - Evaluation & Benchmarking: Runs with-skill and baseline test cases in parallel, grades assertions, aggregates pass rates, timing, and token usage into benchmark reports with an HTML review viewer. - Description Optimization: Generates trigger eval queries and runs an automated loop that rewrites the skill description to improve triggering accuracy, validated on held-out test data. - Use Case: You want to build a skill that formats weekly sales reports. This Skill helps you draft it, creates realistic test prompts, runs them with and without the skill, shows you side-by-side results in a browser viewer, and iterates until the outputs are consistently good. ## Quick Start Help me create a new skill that converts meeting transcripts into structured action-item lists, then test and improve it.
