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 SKILL.md files, running test prompts with and without the skill, grading results against assertions, and optimizing the description for accurate triggering. ## Core Features & Use Cases - Skill Authoring Workflow: Interview-driven drafting of SKILL.md files following progressive disclosure, with guidance on scripts, references, and assets organization. - Evaluation & Benchmarking: Runs test cases in parallel with-skill and baseline configurations, grades assertions, and aggregates pass rates, timing, and token usage into benchmark reports. - Description Optimization: Generates trigger/no-trigger eval queries, reviews them in an HTML interface, and runs an automated loop that rewrites the description to maximize triggering accuracy on held-out test queries. - Use Case: You want to build a skill that converts meeting notes into Jira tickets. This Skill helps you draft it, creates realistic test prompts, runs comparative evaluations, shows results in a browser-based review viewer, and iterates until the outputs satisfy you. ## Quick Start Help me create a new skill that converts my weekly meeting notes into structured Jira tickets, then test it with a few realistic examples.
