author-skill — write skills that trigger and teach
This is the meta skill: it authors and edits the other skills in the rsc catalog. A skill is two things bolted together — a description that fires at the right moment, and a body that makes the agent better once it fires. Most skills fail on the first. Treat them as two separate engineering problems with two separate quality bars.
Where the SDD chain (specify → plan → … → ship) builds product, author-skill builds the tools that build product. Use it whenever a skill is born or edited.
Not this skill — delegate: a product feature specced or planned → ../specify/SKILL.md, ../plan/SKILL.md. An autonomous agent or tool-calling loop → ../building-agents/SKILL.md. Generic project docs or a wiki article → the ../harness/SKILL.md 02-DOCS engine. Bootstrapping a workspace or profiling the user → ../init/SKILL.md.
Read 02-DOCS/wiki/harness/user-profile.md and speak in the register its technical_level records (technical terms, or plain words with analogies); ../init/SKILL.md sets it, and orient owns the voice. With no profile, use analogies and ask once "technical or with analogies?" — skill authoring is itself a technical act, so a non-technical author needs each convention explained, not just named.
