Conciseness

The body is dense, functional lookup data — routing tables, anti-patterns, and exact templates with zero concept re-teaching — and every row is scannable. Minor trims exist: the 'Context Check' paragraph is wordy for a one-sentence suggestion, and the dispatch-not-delivery framing is stated twice ('Do NOT try to answer the ASO question yourself... your job is dispatch, not delivery'), keeping it just below the lean level-5 anchor.

Actionability

Everything is executable: the exact announce string ('→ Loading: <skill-name>'), the exact load path ('skills/<skill-name>/SKILL.md'), copy-paste-ready clarifying questions in the disambiguation playbook, a literal output template block, and hard numeric limits ('Never load more than 3 skills at once'). For an instruction-only skill this is fully copy-paste-ready guidance covering the common cases.

Workflow Clarity

The procedure is a clear numbered 5-step sequence (read → match → announce → load → follow) with an explicit fallback (ask exactly one clarifying question when ambiguous, 'never more'), a hard cap on concurrent skill loads, an anti-patterns section for error recovery, and a formatted handoff template. Routing is neither destructive nor batch, so the validation-cap rule does not apply; the ambiguity-handling loop serves as the checkpoint.

Progressive Disclosure

The routing tables must be inline in SKILL.md to function, and they are exactly where they belong; all section headers make navigation trivial, and the only references ('skills/<skill-name>/SKILL.md' and the 'app-marketing-context.md' existence check) are one level deep and clearly signaled. No bundle files exist to restructure and no content is misplaced, matching the well-signaled one-level-deep anchor.

Specificity

The description names the domain thoroughly ('ASO, App Store, Google Play, app marketing, paid UA, monetization, retention, reviews, ratings, market-intel, or app-analytics') and one concrete action ('routes any... question to the correct specialist skill in this library'). It stops at a single concrete action, matching the anchor 'names domain and 1-2 concrete actions' rather than the several-action coverage of level 4, while being far more concrete than the generic level-2 anchor.

Completeness

It explicitly answers both questions with concrete trigger phrases: what ('Single entry point that routes any... question to the correct specialist skill in this library') and when ('Use FIRST whenever the user mentions...') plus explicit skip guidance ('Skip this router only when the user explicitly invokes a specific skill'). This mirrors the level-5 exemplar structure exactly.

Trigger Term Quality

Trigger coverage is comprehensive and natural: domain nouns users actually say ('app, App Store, Play Store, keywords, ranking, downloads, revenue, subscriptions, screenshots, icon, reviews, competitors, charts, in-app events, launch, press, or ads'), natural help phrases ('help me with my app', 'I need ASO', 'which skill should I use'), and slash-command forms ('/aso-router', '/aso', 'aso help'). Nothing common appears missing, matching the comprehensive-with-synonyms anchor.

Distinctiveness Conflict Risk

It carves a clear niche (router for one ASO skill library) with distinct slash-command triggers and an explicit skip clause, but its deliberately broad triggers ('whenever the user mentions an app') intentionally overlap with every sibling specialist skill it routes to. The overlap is by design and mitigated by the skip rule, so this sits at 'mostly distinct; minor overlap risk' rather than the minimal-conflict level 5.
