What problem does it solve? Writing a skill that triggers reliably and produces good outputs is hard to get right on the first try. This Skill guides the full lifecycle of skill development — drafting, testing against real prompts, benchmarking with quantitative assertions, collecting human feedback, and optimizing the description for accurate triggering. ## Core Features & Use Cases - Guided Skill Authoring: Interviews the user about intent, edge cases, and output formats, then writes a well-structured SKILL.md following progressive disclosure and writing-style best practices. - Evaluation & Benchmarking: Runs test prompts with and without the skill in parallel, grades outputs against assertions, aggregates pass rates, timing, and token usage, and renders results in an interactive HTML review viewer. - Description Optimization: Generates realistic trigger/no-trigger eval queries and runs an automated optimization loop to improve how reliably the skill gets invoked. - Use Case: You want to build a skill that converts meeting notes into structured action items. This Skill helps you draft it, creates test cases, runs them, shows you the outputs side-by-side with baselines, and iterates until the results satisfy you. ## Quick Start Help me create a new skill that turns my weekly meeting notes into a structured list of action items with owners and deadlines.
