creating-skills

Creates agent skills (a SKILL.md folder plus optional resources) that load in GitHub Copilot, Claude Code and OpenAI Codex: a description that triggers on the right requests, a lean body with progressive disclosure, checkable steps, and a validation pass. Use when packaging repeatable know-how as a skill the agent picks up on its own, splitting a bloated SKILL.md into body plus resources, fixing a skill that fires on the wrong requests or never fires, or adding a skill to this collection, even if the user only says 'turn this into something reusable'. For a command the user runs on purpose, use creating-prompts; to test how an existing skill behaves, use testing-agent-skills.
