Conciseness

The ~40-line body is dense and prescriptive with zero padding: every rule carries non-obvious operational fact (the `ok == true` vs `code == 0` envelope trap, exit-code-10 approval gate, relative-path-only file arguments, QR-code pairing rule). It assumes Claude's competence and explains nothing the model already knows, matching the 'lean and efficient; every token earns its place' anchor — the one justification sentence (misjudging success via the legacy OpenAPI format) is a genuine gotcha, not filler.

Actionability

Guidance is concrete and executable: exact commands (`lark-cli auth qrcode` with `--output`/`--ascii`), exact flags (`--dry-run`, `--format json`, `--as user/bot`), exact envelope fields (`ok`, `risk: "high-risk-write"`, `hint`), and precise procedures (append the confirmation flag to the end of the original argv). It stops short of the 5 anchor because there are no complete copy-paste example invocations for the common cases (e.g. a full `auth login` or qrcode command line with arguments), leaving minor gaps; it is well above 3 since nothing is pseudocode or vague.

Workflow Clarity

The high-risk flow is an explicit, well-checkpointed sequence — exit 10 → stop → show `action`/`risk`/key params to the user → obtain explicit consent → append the hinted flag to the original argv → retry — with a genuine feedback (retry) loop and a hard validation gate (user confirmation). It sits at 4 rather than 5 because the body only sequences this one procedure; the other core workflows (login, identity diagnostics, config init) are deferred to references without inline validation steps, and the multi-step procedures that are present stop just short of full checklists.

Progressive Disclosure

Structure is strong: a clear overview split into general rules, security rules, and a MUST-read trigger-index table that maps trigger conditions to the correct reference file, specifies reading order, and deduplicates repeat reads; all five referenced files exist and are one level deep. Scored against the actual bundle, it lands at 4 rather than 5 because the references directory contains a sixth file, `lark-wiki-token-routing.md`, that is not navigable from SKILL.md — a minor organization gap consistent with the 4 anchor ('references mostly clear; minor organization gaps').

Specificity

The description lists multiple concrete, specific items — "auth login/status/logout", "user vs bot identity", "business-domain permissions (--domain, including all/docs/drive)", "missing scopes", "revoking authorization", "handling _notice JSON" — with actual flags and command names. Coverage of the lark-cli setup/auth domain is comprehensive, matching the score-5 anchor; it exceeds the 4 anchor ('several specific actions; minor gaps') because no meaningful task in its niche is left out.

Completeness

It explicitly answers 'when' with an opening "Use for lark-cli setup/auth tasks:" plus concrete trigger phrases (login/status/logout, missing scopes, revoking authorization, _notice JSON), and answers 'what' by enumerating the specific task areas. This matches the 5 anchor (both what and when explicit with concrete triggers) and clearly exceeds the 4 anchor where the 'when' clause is present but could be more specific.

Trigger Term Quality

Good natural keyword coverage: "auth login", "logout", "missing scopes", "revoking authorization", "identity", "_notice" are phrases a user working with lark-cli would plausibly say. It falls short of the 5 anchor ('comprehensive coverage including synonyms and file extensions') because common variations like "log in"/"sign in", "token", or "who am I" are absent, though this does not drop it to 3 since the terms present are specific and relevant rather than missing common variations wholesale.

Distinctiveness Conflict Risk

The niche is clear and narrow — lark-cli setup/auth, identity, scopes, and notice handling — with distinct trigger terms unlikely to fire for unrelated skills. It sits at the 5 anchor ('clear niche with distinct triggers; minimal conflict risk'); the only conceivable overlap is with sibling lark-* skills, but those share this base by design and the enumerated triggers (auth, scopes, _notice) are uniquely routed here.
