Conciseness

The body is lean and assumes Claude's competence: no concept explanations, just a short safe-start block, terse safety bullets, and a dense one-line-per-command reference table where every token earns its place, matching the 'lean and efficient' anchor.

Actionability

Safe-start gives copy-paste-ready executable commands with real flags, the command table maps each subcommand to its purpose, and the closing line directs Claude to '--help' and 'gog schema drive <command> --json' for exact contracts while telling it not to guess syntax, satisfying the 'fully executable; copy-paste ready' anchor.

Workflow Clarity

Safe-start sequences auth check, schema fetch, then a readonly ls, and the bullets supply validation/safety checkpoints (--readonly, --dry-run, confirm account/object/mutation before writes), so the destructive-skill cap does not apply; it stays at 4 rather than 5 because there is no explicit validate-fix-retry feedback loop for failed writes.

Progressive Disclosure

The skill is under 50 lines, single-purpose, and organized into clear 'Safe start' and 'Commands' sections with no bundle files; the only reference is a one-level-deep, clearly signaled sibling skill (../gog/SKILL.md) plus CLI-integrated --help/schema, matching the simple-skill exception that allows a 5 for well-organized short skills needing no external references.

Specificity

The phrase 'Google Drive operations' names the concrete domain but the action ('operations') is minimal and generic, matching the anchor 'Names the domain but actions are minimal or generic'; it does not list any specific concrete actions that would warrant a 3.

Completeness

It offers a vague 'what' ('Google Drive operations through gog') with no 'when'/'Use when' clause at all; per the rubric guideline a missing explicit trigger guidance keeps it at the 'vague what and no when' anchor and caps it well below the higher levels.

Trigger Term Quality

'Google Drive' and 'gog' are relevant keywords a user might say, but common variations, synonyms, and file extensions (e.g., 'files', 'Docs', 'upload', 'share', '.gdoc') are missing, so it falls at the 'some relevant keywords but missing common variations' anchor rather than comprehensive coverage.

Distinctiveness Conflict Risk

Scoping to a specific service (Google Drive) and a specific CLI ('gog') makes it mostly distinct with only minor overlap risk against sibling gog-* skills; it lacks the rich explicit triggers of the 5 anchor but is clearly above the broad-overlap lower anchors.
