Conciseness

The body is dense and operational with no explanation of concepts Claude already knows — every line is a routing rule, command, or constraint. Minor trimming is possible (the schema-lookup paragraph under Shortcuts reiterates Help-avoidance rules already stated in 执行契约), which fits anchor 4 rather than the fully lean anchor 5.

Actionability

Every route is a copy-paste-ready command with concrete flags and placeholders (e.g. `dws todo +assign --to "张三" --task "<标题>" --format json`, `--priority 10|20|30|40`, `python scripts/todo_batch_create.py <todos.json> --dry-run`), with a full atomic-command skeleton table. This matches anchor 5 fully executable guidance covering the common cases.

Workflow Clarity

Multi-step processes are explicitly sequenced (执行_contract read-first rule, numbered 路由优先级 1–5, Golden Routes intent table) with explicit validation checkpoints: mandatory post-write read-back verification ("写后必须核验"), reconciliation instead of blind replay for non-idempotent writes, and a dry-run planDigest confirmation gate for batch creation. Feedback loops for error recovery (unknown flag → Help once; unknown command → no Help, report drift) are present, matching anchor 5.

Progressive Disclosure

The SKILL.md is a clear overview with well-labeled, one-level-deep references (intent disambiguation, lite recipes, composite lifecycle, full command reference — all verified to exist) plus bundled scripts. However, `references/recipes/conventions.md` is an orphan: it is referenced nowhere in SKILL.md or the other reference files, so that content is not navigable from the skill entry point — a minor organization gap that fits anchor 4 rather than 5.

Specificity

The what-clause is just "钉钉待办 / TODO", but concrete actions are enumerated through the trigger list (创建待办、指派任务、标记完成、查待办、批量建待办、逾期待办). It lists several specific actions with minor gaps (update, delete, comment, and attachment operations are never mentioned), which matches anchor 4 rather than 5.

Completeness

Both what and when are present: the when is explicit with concrete trigger phrases plus explicit exclusions ("不做日报周报（走 dingtalk-misc）…日程（走 dingtalk-calendar）"), but the what is a terse domain name plus command prefix ("钉钉待办 / TODO … 命令前缀：dws todo") without stating capabilities. This matches anchor 4 (both present, what could be more explicit) rather than anchor 5.

Trigger Term Quality

The "Use when 用户说" clause gives natural spoken phrases with synonyms (待办/TODO/任务提醒) across create, assign, complete, query, urgent, recurring, batch, and overdue intents. A few natural terms are missing (e.g. 修改待办/更新待办, 删除待办), so it fits anchor 4 rather than the comprehensive anchor 5.

Distinctiveness Conflict Risk

It carves a clear DingTalk-todo niche with distinct triggers and explicitly deflects adjacent domains to sibling skills (dingtalk-misc for reports/approvals, dingtalk-calendar for schedule), plus a command prefix. Conflict risk is minimal, matching anchor 5.
