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 writes a structured SKILL.md following progressive disclosure and skill-writing best practices. - Evaluation & Benchmarking: Spawns parallel with-skill and baseline runs, grades outputs against quantitative assertions, and aggregates pass rates, timing, and token usage into benchmark.json with mean and standard deviation. - Description Optimization: Generates realistic should-trigger and should-not-trigger queries, runs an automated train/test optimization loop, and selects the best description by held-out test score. - Use Case: You want a skill that converts meeting notes into Jira tickets. This Skill helps you draft it, creates test prompts, runs comparative evaluations in an HTML review viewer, collects your feedback, and iterates until the outputs are consistently correct. ## Quick Start Help me create a new skill that turns my weekly meeting notes into structured action items, then test and improve it.
