Triggers when the user wants to create, edit, improve, or debug an OpenLoaf custom Skill. Typical phrasings: "help me create a skill", "build a new skill", "turn what we just did into a skill", "write a skill that auto-XX", "tweak this skill", "why isn't this skill triggering", "edit my custom skill", "add a global skill", "add a skill to the current project". Any create / modify / tune request touching a `SKILL.md` under `.openloaf/skills/` should load this skill. Also applies when the user wants to understand the skill format, troubleshoot triggering issues, or solidify a conversation workflow into a reusable capability. Not for: modifying built-in skills (e.g. file-ops, email-ops) — those are read-only capabilities shipped with the platform.
