Conciseness

The body is mostly efficient — compact tables, a lean request helper, no explanation of concepts Claude already knows — but it could be tightened: the 'Error Handling' section duplicates checks already built into av_get, and 'When to Use' plus parts of 'Limitations' are generic boilerplate filler. Not 2 because padding is limited to a few short sections; not 4 because the duplication and filler are noticeable.

Actionability

Fully executable, copy-paste-ready guidance: a complete av_get helper with key-redaction and error handling, quick-start examples spanning quotes, time series, fundamentals, income statements, crypto, economic indicators, and technical indicators, plus install and API-key-setup commands. The examples cover the common cases comprehensively.

Workflow Clarity

A clear sequence runs from key setup through installation, request pattern, examples, parameters, and rate limits, with validation checkpoints embedded in the helper (HTTP status, error/quota keys, JSON shape). Not 5 because there is no explicit cache-first/retry feedback loop despite the rate-limit discussion; not 3 because checkpoints are present, not merely implicit. The skill is read-only (non-destructive), so the destructive-cap rule does not apply.

Progressive Disclosure

A single-file skill with well-organized sections and the API reference compressed into compact tables rather than inlined as prose. No bundle files exist, and none are strictly required. Not 5 because the ~140-line body exceeds the simple-skill threshold and endpoint detail (e.g., the 50+ technical indicators) could be offloaded to a one-level-deep reference file; not 3 because structure and placement are good, not mixed with content that clearly belongs elsewhere.

Specificity

The single concrete action 'Access 20+ years of global financial data' is backed by a comprehensive enumeration of asset classes (equities, options, forex, crypto, commodities, economic indicators) and '50+ technical indicators'. Not 5 because only one action verb is given (no fetch/analyze/quote-style actions); not 3 because coverage of the domain is comprehensive rather than partial.

Completeness

It clearly answers 'what' (access 20+ years of global financial data across the listed categories) but has no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. Not 2 because the 'what' is concrete and detailed, not vague.

Trigger Term Quality

Natural domain keywords like 'equities', 'forex', 'crypto', 'commodities', 'economic indicators', and 'technical indicators' match what users would say. Not 5 because common variations users actually say — 'stock prices', 'market data', 'exchange rates', 'ticker' — are missing; not 3 because keyword coverage is good rather than partial.

Distinctiveness Conflict Risk

The niche (global financial market data access) is clear and would rarely trigger for an unrelated skill. Not 5 because without explicit trigger phrases it could still overlap with other market-data or finance skills; not 3 because it is far more specific than 'somewhat specific'.
