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 you through drafting a skill, running structured test cases with baselines, grading results quantitatively, and iterating based on real feedback instead of guesswork. ## Core Features & Use Cases - Guided Skill Authoring: Interviews you about intent, trigger contexts, and output formats, then writes a well-structured SKILL.md following progressive disclosure and writing-style best practices. - Evaluation Harness: Spawns parallel with-skill and baseline subagent runs, drafts assertions, captures timing and token data, grades outputs, and aggregates results into benchmark.json with pass-rate deltas. - Description Optimization: Generates realistic should-trigger and should-not-trigger queries, runs an automated train/test optimization loop, and applies the best-performing description to improve triggering accuracy. - Use Case: You want a skill that formats weekly status reports. This Skill helps you draft it, creates three realistic test prompts, runs them with and without the skill, shows you a side-by-side review viewer, and iterates until the outputs satisfy you. ## Quick Start Help me create a new skill that converts meeting notes into structured action items, then test and improve it.
