Create Skill

Create one new Muse skill. Use this skill only for explicit Muse skill creation requests, not for ordinary skill usage, code changes, benchmark tasks, or third-party skill/plugin systems.

Two scopes exist (ADR 8975):

• Project scope (the default): the skill lives in the current workspace at .agents/skills/<skill-id>/.
• Personal scope (the user asked for a "personal", "user", or "cross-project" skill): the skill belongs in the managed personal root $CONFIG_DIR/skills/<skill-id> ($XDG_CONFIG_HOME/muse, else $HOME/.config/muse). You stage and validate the draft in the workspace, then hand the user one muse skills install command — the store performs the managed install (files + provenance), so skills update and skills uninstall keep working on it.
