Conciseness

The ~35-line body is lean with zero concept explanations Claude already knows: a compact routing table, a one-line tie-break rule, two quick-start commands, and three rules. Every section earns its place, including the 'Related (packaged separately)' note which prevents mis-routing.

Actionability

Concrete, executable commands are present ('python3 finance/skills/saas-metrics-coach/scripts/metrics_calculator.py --help', 'cat finance/skills/financial-analyst/SKILL.md'), but the routing table uses 'skills/financial-analyst/' while the quick start uses 'finance/skills/financial-analyst/' and the working directory the commands assume is never stated. These minor gaps keep it below fully copy-paste-ready.

Workflow Clarity

As a simple single-decision skill, the routing action is unambiguous: match request signals against the table, 'Route to exactly one skill, then follow that skill's workflow', with an explicit tie-break rule for overlapping matches ('ask whether the user wants statement-level analysis... or SaaS operating metrics') and a standing validation rule ('Always validate financial outputs against the user's source data').

Progressive Disclosure

Sections are well organized and references are one level deep (routing table Path column, quick-start commands), but path prefixes are inconsistent between the routing table ('skills/financial-analyst/') and the quick start ('finance/skills/financial-analyst/'), and the referenced sibling-skill paths cannot be verified from this router alone. Minor organization gaps, not missing structure.

Specificity

The description lists multiple concrete actions with comprehensive coverage of all three bundled skills ('ratio analysis, DCF valuation, budget variance, rolling forecasts', 'ARR/MRR, churn, CAC/LTV, NRR, quick ratio', 'close calendar, reconciliations, flux review'), which matches the anchor 5 example. However, the rubric guideline penalizes second-person voice, and 'you need to pick the right one' is second person, reducing the score by 1.

Completeness

Both halves are explicit: what ('Router/index for the finance skills bundled in this plugin: financial-analyst (...), saas-metrics-coach (...) and month-end-close (...)') and when ('Use when a finance request doesn't obviously match one skill and you need to pick the right one') with concrete example trigger phrases. This matches the anchor 5 example structure exactly.

Trigger Term Quality

Natural user vocabulary is comprehensively covered: 'churn', 'CAC/LTV', 'budget variance', 'month-end close', 'reconciliations', 'flux review', plus literal example utterances users would actually say ('analyze these financials', 'how healthy are my SaaS metrics'). No meaningful natural synonyms for this domain are missing, so it fits anchor 5 rather than 4.

Distinctiveness Conflict Risk

The trigger clause 'when a finance request doesn't obviously match one skill' carves out a distinct disambiguation niche relative to the sub-skills it routes to, minimizing conflict with them by design. Clear niche, minimal conflict risk — anchor 5, not 4, because the scoping is explicit rather than merely 'mostly distinct'.
