What problem does it solve? Writing a skill that triggers reliably and produces good outputs is hard to do by intuition alone. This Skill guides the full lifecycle of skill development: drafting SKILL.md files, running test prompts with and without the skill, grading results against assertions, and optimizing the description field for accurate triggering. ## Core Features & Use Cases - Guided Skill Authoring: Interviews the user about intent, trigger contexts, and output formats, then drafts a SKILL.md following progressive disclosure and writing-style best practices. - Evaluation & Benchmarking: Runs test prompts in parallel with-skill and baseline configurations, grades outputs against assertions, and aggregates pass rates, timing, and token usage into benchmark reports with an interactive HTML review viewer. - Description Optimization: Generates realistic should-trigger and should-not-trigger queries, then runs an automated train/test optimization loop to improve the skill's triggering accuracy. - Use Case: You want a skill that formats weekly sales spreadsheets. This Skill helps you draft it, creates three realistic test prompts, runs them with and without the skill, shows you a side-by-side comparison in a browser viewer, and iterates based on your feedback until the outputs are consistently correct. ## Quick Start Help me create a new skill that converts meeting transcripts into structured action-item lists, then test it with a few example prompts.
