The body is lean and assumes Claude's competence — it never explains what Google Drive or permissions are, and every line (prerequisite refs, commands, classification, safety) earns its place, matching the level-3 anchor.

Three fully executable gog commands with real flags (--readonly, --max, --json, --wrap-untrusted) plus a concrete classification taxonomy and required evidence fields are copy-paste ready, matching the level-3 anchor.

The sequence (read prerequisites → run inventory → classify → remediation if requested) is clear, and the destructive/batch remediation branch has an explicit validation checkpoint ("use each mutation's --dry-run before any approved write"), satisfying the level-3 anchor.

Under 50 lines with no bundle directories, the body is well-organized into sections and points one level deep to clearly signaled sibling skills ("Read ../gog/SKILL.md and ../gog-drive/SKILL.md first"), matching the simple-skill level-3 guidance.

"sharing and permission audits" names the domain and a concrete action with tool "gog", but it is a single composite action rather than the multiple distinct actions (e.g. extract/fill/merge) the level-3 anchor requires.

The "what" is clear (read-only sharing/permission audits), but there is no "Use when..." or equivalent explicit trigger guidance, which per the judging guidelines caps completeness at 2.

"Google Drive", "sharing", "permission", and "audits" are relevant natural terms, but the single phrase omits common variations users might say (e.g. "shared links", "access", "Drive files") that the level-3 anchor expects.

The narrow read-only Google Drive sharing/permission audit niche tied to a specific tool "gog" is clearly distinguishable and unlikely to trigger the wrong skill, matching the level-3 anchor.
