Conciseness

Every line is operational: three safe-start commands, a one-line purpose per command, and delegation of flag details to '--help' and 'gog schema'. No concept explanations or padding exist, matching 'Lean and efficient; assumes Claude's competence; every token earns its place'.

Actionability

The safe-start block is copy-paste ready and the discovery pattern 'gog drive <command> --help' is executable, but only one command (ls) has an actual invocation example; the other 27 commands have purposes without usage. Fits 'Mostly executable guidance; concrete code or commands with minor gaps' rather than level 5, which requires examples covering the common cases.

Workflow Clarity

A clear startup sequence (auth check, schema inspection, read-only ls) with explicit safety checkpoints for the destructive commands offered: '--readonly', '--dry-run before supported writes', and 'Confirm the exact account, object, and mutation before any write or delete'. Not level 3 because validation guidance is explicit despite destructive/batch commands; not level 5 because there is no error-recovery feedback loop (fix-and-retry) for failed operations.

Progressive Disclosure

The body is a well-organized overview that delegates detail to runtime discovery (--help, gog schema) and one clearly signaled reference (../gog/SKILL.md). However, no bundle files exist, the external relative path sits outside the skill directory, and the 28-command table is inline reference material. Fits 'Good structure; most content is appropriately placed; minor organization gaps' rather than level 5's well-signaled bundle references.

Specificity

The description names the domain ("Google Drive") but the only action word is the generic "operations"; no concrete capabilities like upload, share, search, or download are stated. This matches the anchor 'Names the domain but actions are minimal or generic' rather than level 3, which requires 1-2 concrete actions.

Completeness

There is a clear domain-level 'what' (Google Drive operations via gog) but no 'when' clause whatsoever, which caps completeness at 3 per the judging guidelines. Not level 4 because no trigger guidance is present even weakly.

Trigger Term Quality

"Google Drive" is a specific, natural phrase users would say, but it is essentially the only trigger term; common variations like "Drive files", "upload to Drive", or "shared drive" are missing. Not level 2 because the keyword is specific and natural, unlike the generic 'Works with files'.

Distinctiveness Conflict Risk

"Google Drive" carves a clear niche with minimal conflict risk, but the terse phrasing provides no disambiguating triggers against closely related sibling skills (e.g., other gog-backed Google services). Fits 'Mostly distinct; minor overlap risk with closely related skills' rather than level 5, whose example earns distinctiveness through explicit trigger phrases.
