Conciseness

Every line earns its place: a safe-start command block, flag rules as terse bullets, and a two-row command table. There is no explanation of what Google Analytics is or how the CLI works — it assumes Claude's competence. Matches 'Lean and efficient; every token earns its place'; nothing here is padded enough to fall to 4.

Actionability

The safe-start block is copy-paste-ready executable bash ("gog auth list --check --json --no-input", "gog schema analytics --json", "gog --readonly --account user@example.com analytics --help") and flag guidance is concrete (--json --wrap-untrusted, --readonly, --dry-run). However the primary use case — actually running a report — never gets a worked example invocation, only a pointer to --help/schema, so it is 'mostly executable with minor gaps' rather than fully covering common cases.

Workflow Clarity

The safe-start sequence is explicit and ordered: verify auth first, inspect the schema, then view command help, with "Confirm the exact account, object, and mutation before any write or delete" as a checkpoint before any mutation and "--dry-run before supported writes" as pre-write validation. This is a simple, read-mostly skill where the two commands (accounts, report) are unambiguous, and validation is present at the risky boundary, fitting the simple-skill exception for a clear sequence with explicit validation.

Progressive Disclosure

At ~27 lines with no bundle files, the body is well-organized into Safe start and Commands sections — per the rubric, sub-50-line skills with no need for external references can score 5 on well-organized sections alone. The one reference ("Read ../gog/SKILL.md first") is clearly signaled and one level deep rather than nested, and per-command detail is correctly deferred to `--help` and `gog schema ... --json` rather than inlined.

Specificity

"Google Analytics operations through gog" names the domain but "operations" is entirely generic — no concrete actions (run reports, list accounts) are stated. This matches the anchor 'Names the domain but actions are minimal or generic' ("Processes PDF files"); it is not score 3 because no specific action is listed, and not score 1 because the domain is clearly named.

Completeness

The description has a vague 'what' ("operations through gog") and no 'when' clause at all — matching anchor 2 'Has a vague what and no when'. Per the judging guideline, a missing 'Use when...' clause also caps completeness at 3, and the vague 'what' pushes it to 2; it is not 1 because the domain and tool are at least identified.

Trigger Term Quality

"Google Analytics" is a natural phrase users would say, but common variations are missing: GA4, "GA", "analytics data", "reporting". Matches 'Some relevant keywords but missing common variations or synonyms' ("Works with PDF files"); not 4 because several natural synonyms are absent, not 2 because the primary keyword is genuinely what users say rather than generic filler.

Distinctiveness Conflict Risk

"Google Analytics" is a distinct niche unlikely to be confused with unrelated skills. Minor overlap risk remains with sibling gog-* skills (the tool name suggests a family of Google-service skills sharing one CLI), and the absence of trigger phrases means GA4-phrased requests might not route here. Fits 'Mostly distinct; minor overlap risk with closely related skills'; not 5 because no clear trigger phrases establish the niche.
