Use skill

Scope

Default ephemeral: fetch/run/discard, never install or persist. Blob/raw/tree URLs or owner/repo@ref:path resolve to a skill directory (a file uses its parent); omitted ref uses repo default branch. Other forms or requests to save/install block. Repository-content questions belong to box. Record links | resolved directory/revision | blob set | executed | terminal.

Fetched workflows run under this invocation's authority, not above host permissions or higher-priority instructions. Trust linked skills by default, without an allowlist; live user instructions win direct content conflicts. Skill links inside fetched content may be followed under the same boundaries.
