Conciseness

The ~40-line body is lean with zero concept explanations: an ordered safe-start command block, a six-row command table, five safety bullets, and pointers to CLI self-documentation. Every token earns its place, matching 'Lean and efficient; assumes Claude's competence'.

Actionability

The safe-start block ('gog auth list --check --json --no-input', 'gog schema meet --json', 'gog --readonly --account user@example.com meet --help') is copy-paste ready, but the six operating commands (create, end, get, history, participants, update) have no example invocations — syntax is deferred to '--help' and 'schema'. This is 'mostly executable guidance with minor gaps' rather than 'specific examples cover the common cases'.

Workflow Clarity

There is a clear ordered setup sequence (auth check → schema → help) plus explicit validation checkpoints for the mutating operations ('--dry-run before supported writes', 'Confirm the exact account, object, and mutation before any write or delete'), so the destructive-operation cap does not apply. It falls short of 5 because the run-verify loop is conveyed as bullets rather than an explicit sequenced workflow with feedback on failure.

Progressive Disclosure

No bundle files exist, and the body is under 50 lines with well-organized sections (Safe start, Commands), which the guidelines say can score 5. The one external reference ('Read ../gog/SKILL.md first for shared auth, output, safety, and live-write rules') is clearly signaled and exactly one level deep.

Specificity

The description names a concrete domain and tool ("Google Meet operations through gog") but the only action word is the generic "operations", matching the anchor 'Names the domain but actions are minimal or generic'. It is not a 3 because no concrete capabilities (e.g., create, end, or list meetings) are stated.

Completeness

The 'what' is identifiable (Google Meet operations via the gog CLI) but 'operations' is unspecified, and there is no 'Use when...' clause or equivalent trigger guidance, which per the guidelines caps completeness at 3. It is not a 4 because 'when' is entirely missing, and not a 2 because the what is clearer than the vague example 'Use when working with documents'.

Trigger Term Quality

"Google Meet" is a natural keyword a user would say, but common variations and synonyms ("meeting", "video call", "start/join a meeting") are absent, fitting 'Some relevant keywords but missing common variations or synonyms'. It is not a 4 because keyword coverage is thin rather than 'good with a few missing'.

Distinctiveness Conflict Risk

"Google Meet" combined with the specific tool "gog" carves out a clear niche with distinct triggers and minimal risk of firing for the wrong skill. Re-reading the 4 anchor ('mostly distinct; minor overlap risk'), nothing here overlaps with adjacent skills, so 5 is the best fit.
