What problem does it solve? Hand-written skill files drift from canonical structure, fail to trigger reliably, and leak sensitive data into public releases. This Skill owns the entire skill lifecycle — scaffolding, validation, canonicalization, effectiveness testing, and trigger tuning — so every skill ships in a proven, compliant shape. ## Core Features & Use Cases - Scaffold and Update: Create new skills with canonical TitleCase naming, flat two-level trees, frontmatter with USE WHEN triggers, routing tables, gotchas, and examples; extend existing skills with new workflows or tools. - Validate and Canonicalize: Audit skills against the SkillSystem.md doctrine — naming, frontmatter format, routing integrity, hygiene gates — and repair non-compliant structures automatically. - Test and Optimize: Race with-skill agents against no-skill baselines on realistic prompts, then tune the frontmatter description with 20 should/shouldn't-fire probes to fix triggering accuracy. - Use Case: You ask to create a recipe-management skill. The Skill reads the doctrine, raises the directory with Workflows/ and Tools/, drafts SKILL.md, runs the hygiene gate, and offers a TestSkill run to prove it actually improves outcomes. ## Quick Start Ask the agent to create a new skill for a task you have in mind, or to validate, test, or improve an existing skill by name.
