Skill Creator

This is the meta-skill that builds other skills. It walks you through drafting a new skill, writing test cases, running evals, and iterating based on results. The workflow is surprisingly structured: capture intent, generate a draft, run quantitative benchmarks while you review qualitative output, then refine until it works. It also includes a separate optimizer for skill descriptions to improve triggering accuracy. What's smart here is the flexibility. If you already have a draft, jump straight to testing. If you just want to vibe without formal evals, it accommodates that too. The documentation explicitly coaches Claude on explaining technical terms based on user context, which matters when your audience ranges from experienced developers to plumbers opening a terminal for the first time.

Skill Creator

Create or improve a reusable capability, verify the user's actual outcome, and deliver the declared source, package or installed result. Start at the unfinished stage. Preserve an existing skill's name, supported work and user-owned data.

Use the current user's authorization and actual host capabilities before these defaults. A tool's availability, a long conversation or the word “optimize” does not authorize history access, new capabilities, agent fan-out or publication.
