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 outputs against assertions, aggregating benchmark statistics, 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: Spawns parallel with-skill and baseline runs, grades outputs against assertions, and aggregates pass rates, timing, and token usage into benchmark.json with mean, stddev, and deltas. - Description Optimization: Generates realistic trigger/no-trigger eval queries, runs an automated optimization loop with train/test splits, and applies the best-performing description. - Use Case: You want a skill that formats weekly sales reports. This Skill helps you draft it, creates test prompts, runs them with and without the skill, shows results in a browser-based review viewer, and iterates until the outputs pass your review. ## Quick Start Help me create a new skill that converts meeting transcripts into structured action-item lists, then test and improve it.
