Conciseness

The ~28-line body is lean and functional with zero padding — a signal-to-path routing table, two copy-paste commands, and three terse rules. It assumes Claude's competence with no explanation of known concepts, matching anchor 5 exactly.

Actionability

Concrete executable commands ('cat business-growth/skills/customer-success-manager/SKILL.md', 'python3 …/health_score_calculator.py --help') plus a request-signal table. Minor gaps keep it below anchor 5: the '<skill>' placeholder in the load instruction and table paths ('skills/customer-success-manager/') that omit the 'business-growth/' prefix used elsewhere.

Workflow Clarity

The routing action is unambiguous: match request signals, ask one clarifying question if multiple rows match (an explicit checkpoint), load the matched SKILL.md, and follow that skill's workflow with the rule 'Route to exactly one skill'. No destructive or batch operations, so the validation cap does not apply.

Progressive Disclosure

Under 50 lines with well-organized sections (Routing table, Quick start, Rules), and its external references — the four sibling SKILL.md paths — are one level deep and clearly signaled in the table, which is ideal index/router structure per the simple-skill note.

Specificity

Lists multiple concrete actions per skill ('health scoring, churn risk, expansion', 'RFP analysis, competitive matrices, PoC planning', 'pipeline, forecast accuracy, GTM efficiency'), but 'contract-and-proposal-writer' is named with no capability detail — a minor coverage gap that keeps it below anchor 5 and well above the 1-2-action anchor 3.

Completeness

Explicitly answers both 'what' (router/index for the 4 bundled skills with their capabilities) and 'when' via an explicit 'Use when a growth/revenue request doesn't obviously match one skill…' clause with concrete trigger phrase examples — a clear anchor 5 match.

Trigger Term Quality

Good natural keyword coverage including example user phrasings ('which accounts are at risk', 'should we bid on this RFP'), churn risk, RFP, pipeline, forecast accuracy. Common synonyms like 'customer success', 'retention', or 'renewals' are missing, so it falls short of anchor 5's comprehensive synonym coverage but clearly exceeds anchor 3.

Distinctiveness Conflict Risk

The trigger is scoped to ambiguity ('doesn't obviously match one skill'), but the router's keywords inherently overlap with its four child skills (e.g., a proposal request matches both the router and contract-and-proposal-writer) — mostly distinct with minor overlap risk, anchor 4 rather than a clear niche with minimal conflict.
