Conciseness

The body is dense and mostly earns its tokens (per-skill routing rules, decision branches), but the grill-with-docs vs. grill-me distinction is explained three separate times (main flow step 1, Standalone, Vocabulary), the /handoff usage is spelled out in both the main flow and Phase boundaries, and several entries carry rationale that could be trimmed — 'mostly efficient but could be tightened'. Not a 4 because the repetition across sections is noticeable rather than minor.

Actionability

As an instruction-only skill it gives concrete, specific guidance: named slash commands for every branch, binary decision questions ("能否在对话中解决所有问题？"、"这是 multi-session build 吗？"), and concrete paths and locations (`.scratch/<feature>/issues/`、`prototype/<name>`、`.env` and GitHub secrets). Not a 5 because some routing criteria remain judgment calls (e.g. when an effort is '巨大而模糊') without a tie-breaker.

Workflow Clarity

The main flow is a clearly sequenced decision tree (idea -> grill -> branch on prototype/multi-session -> tickets -> implement -> review) with explicit checkpoints such as the context-hygiene rule (one unbroken window through /to-tickets) and the smart-zone compact guidance. No destructive or batch operations are involved, so the validation-loop cap does not apply; not a 5 because the phase-boundary decision tree itself is acknowledged as ambiguous and deferred to a missing file.

Progressive Disclosure

Section structure is good (main flow, on-ramps, codebase health, vocabulary, phase boundaries, standalone, precondition), but the body's only bundle reference — [PHASE-BOUNDARIES.md](PHASE-BOUNDARIES.md) — points to a file that does not exist in the bundle (no references/ directory, no such file), and substantial per-skill detail in Standalone/Vocabulary is inlined that could live in reference files. Not a 4 primarily because the one reference offered is broken, leaving a whole promised topic undeliverable.

Specificity

The description names its domain ("本仓库所有 skills" 的路由) and one concrete action ("询问当前情境适合哪个技能或流程"), but stops there — it lists no further capabilities, so it matches 'names domain and 1-2 concrete actions, but not comprehensive'. It is not a 4 because coverage consists of a single routing action rather than several specific actions.

Completeness

The "what" is clear (asks which skill or flow fits the current situation; router for all skills in this repo), but there is no "use when" clause or equivalent trigger guidance anywhere — per the judging guidelines this caps completeness at 3. It is not a 2 because the "what" half is specific, not vague.

Trigger Term Quality

The only keywords are the generic "技能", "流程", and "路由器" — one or two generic terms with none of the natural phrases a user would actually say (e.g. "该用哪个 skill"、"which skill should I use"), matching 'one or two generic keywords; missing the natural phrases users say'. It is not a 3 because no relevant synonyms or variations appear at all.

Distinctiveness Conflict Risk

The router framing ("它是本仓库所有 skills 的路由器") gives it a distinct purpose, but by definition it claims relevance to every other skill in the repo, so overlap risk with similar meta/navigation skills remains — 'somewhat specific but could still overlap'. It is not a 4 because the scope is explicitly all skills, not a narrow niche with distinct triggers.
