Conciseness

The body is almost entirely imperative domain rules with no padding explaining concepts Claude already knows, but step 7 of section 4 ("For an authorized conversation archive that includes linked materials, derive the requested set from every captured root...") and the multi-paragraph auth/needs_refresh block are dense run-on policy walls that could be tightened or moved to a reference file. This fits 'mostly efficient but could be tightened' better than anchor 4, since the verbosity is substantial rather than minor.

Actionability

Gives copy-paste-ready commands throughout: `lark-cli --version`, `lark-cli skills list --json`, `lark-cli skills read lark-doc/references/lark-doc-fetch.md`, `lark-cli --profile "<authorized-profile>" auth status --json`, plus concrete env vars (LARK_CLI_NO_PROXY=1). Specific behavior thresholds (exit 10, `ok == true`, `confirmation_required`) cover the common cases; this matches the fully-executable anchor.

Workflow Clarity

A clear four-step sequence (confirm runtime → select embedded guide → load instructions → inspect/execute/verify) with explicit validation checkpoints: dry-run previews, an exit-10 human-confirmation gate for high-risk writes, batch reconciliation with a worked 'partial: 1/3' example, and an auth-error recovery branch loading `lark-shared`. Validation for destructive/batch operations is present, so the workflow-clarity cap does not apply; this matches the anchor with feedback loops and error recovery.

Progressive Disclosure

Both referenced bundle files exist (references/recording-lookup.md, references/document-layout.md) and are clearly signaled with when-to-read conditions ("read [recording lookup](references/recording-lookup.md) before searching"), and domain detail is delegated one level deep to embedded CLI guides. Not a 5 because substantial policy content (batch reconciliation, conversation-archive derivation, needs_refresh handling) is inlined in the body where a reference file would improve navigation.

Specificity

Names several concrete actions — "Routes any Feishu/Lark/Doubao operation... through the version-matched lark-cli domain guide... then executes and verifies the task" and "recording lookup by date (按日期找会议录音)" — plus a long domain list (docs, drive, sheets, Base, wiki, minutes, meetings, calendar, IM, mail, tasks, approval, apps, auth/scope). Not a 5 because the domain items are bare nouns: the per-domain actions are not enumerated, leaving minor coverage gaps.

Completeness

Clearly answers both: what — "Routes any Feishu/Lark/Doubao operation... through the version-matched lark-cli domain guide embedded in the installed CLI, then executes and verifies the task" — and when — the explicit "Use for 飞书/Lark/Doubao docs, drive, sheets..." trigger list. Written in third person ("Routes", "executes"), so the voice penalty does not apply.

Trigger Term Quality

Good natural-term coverage including brand synonyms in both languages (Feishu/Lark/飞书/Doubao) and a natural Chinese phrase (按日期找会议录音), plus product-area nouns users would say (docs, sheets, calendar, mail, approval). A few natural terms are missing — e.g. Chinese product names like 多维表格 (Base) or 妙记 (minutes) — so it fits 'good keyword coverage; a few natural terms missing' rather than the comprehensive anchor.

Distinctiveness Conflict Risk

Clear niche (operations on Feishu/Lark/Doubao via lark-cli) with an explicit boundary — "This is the single Lark entry point; use ima-copilot instead for Tencent IMA" — that actively routes the nearest conflicting product elsewhere. Minimal conflict risk.
