Quality

Content

86%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A lean, dense constraint document that respects the reader's intelligence and points to the right external docs at the right depth. Validation is explicit and scoped honestly ("Keep proof claims within the checks actually executed"), with the only gaps being delegated check commands and the absence of failure-handling guidance.

DimensionReasoningScore

Conciseness

Every sentence carries non-obvious constraint information (ownership boundaries, retired-SDK warnings, dispatch/receipt ordering invariants) with zero padding and no explanation of concepts Claude already knows, matching the level-5 'every token earns its place' anchor.

5 / 5

Actionability

Concrete file paths, a specific env var (BYOK_VERCEL_AI_GATEWAY_API_KEY), and specific invariants make the guidance mostly executable, but the actual check commands are delegated to the integration README rather than given inline, so it is not copy-paste ready as the level-5 anchor requires.

4 / 5

Workflow Clarity

A clear sequence is present (read the seam docs, make consumer changes, run focused checks, then typecheck) with explicit validation ("Run the affected focused checks listed in the integration README, then the repository's required typecheck"), so the destructive-operation cap does not apply. It falls short of level 5 because the sequence is implicit and no error-recovery feedback loop is given for failed checks.

4 / 5

Progressive Disclosure

Under 50 lines with well-organized sections and clearly signaled one-level-deep references ("Read [the local contributor guide]... and [the integration README]... for the affected seam"); no bundle files exist, so there is nothing to restructure — this fits the rubric's simple-skill level-5 case.

Description

78%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, boundary-aware description that names concrete consumer areas and gives explicit use-for guidance while explicitly delegating financial operations to the Platform billing skill. The main weakness is that the trigger clause covers only the editor-integration/BYOK path, leaving some of the skill's own capability areas without explicit trigger phrases.

Suggestions

Broaden the 'Use for...' clause to explicitly cover the other capability areas, e.g. 'Use when working on billing consumers, credit display, paid AI admission, or webhook delivery — including editor integration and local insiders/BYOK development'.

Add natural synonyms users might say, such as 'subscription', 'payment', or 'pricing', to the trigger terms so the description matches how users phrase billing-related requests.

DimensionReasoningScore

Specificity

The description lists several concrete capability areas ("billing consumers, credit display, paid AI admission, or signed webhook delivery"), but the generic verb "Work on" keeps it below the level-5 anchor's concrete action verbs; it clearly exceeds level 3's 1-2 actions.

4 / 5

Completeness

Both "what" (the four consumer areas) and "when" ("Use for editor integration and local insiders/BYOK development") are explicit. Not level 5 because the when-clause covers only a subset of the what — nothing explicitly triggers for webhook-delivery or credit-display work.

4 / 5

Trigger Term Quality

Good natural keyword coverage: "billing", "credit display", "webhook delivery", "editor integration", "insiders/BYOK". A few natural terms are missing (e.g., "subscription", "payment", "pricing"), so it does not reach level 5's comprehensive synonym coverage.

4 / 5

Distinctiveness Conflict Risk

It carves out a clear niche and explicitly delineates the closely related skill ("Platform billing handles financial operations and policy"), which is stronger than level 4's "minor overlap risk with closely related skills" — the boundary is stated rather than left to chance.
