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.

The body is an efficient, highly actionable API reference with clean progressive disclosure to real bundle files. Its only soft spot is workflow clarity, which relies on an error-handling snippet rather than explicit numbered validation checkpoints.

Suggestions

Add a short numbered 'Typical workflow' sequence (set key → install deps → call av_get → check Error Message/Note/Information) so the validation loop is explicit rather than implied by the error-handling snippet.

Trim redundant inline comments like '# Add delay to avoid rate limits' since the surrounding code is self-explanatory.

Move the 'as of 2026' free-tier rate-limit figure into a clearly dated note so it does not silently stale the conciseness budget.

DimensionReasoningScore

Conciseness

Mostly lean — concrete request pattern, scannable tables, and minimal concept explanation — with only minor trimmable bits such as the 'Add delay to avoid rate limits' comment and the slightly long quick-start block.

4 / 5

Actionability

Fully executable guidance: a reusable `av_get` helper, copy-paste quick-start examples spanning stocks, fundamentals, crypto, economic indicators and technicals, plus runnable install and error-handling code.

5 / 5

Workflow Clarity

Clear sequenced setup (get key, export env var, install deps, call helper) with an explicit error-handling section acting as validation; no destructive/batch operations so the cap does not apply, though formal checkpoints are implicit rather than enumerated.

4 / 5

Progressive Disclosure

SKILL.md is a tight overview with an API-categories table and common parameters kept inline, while eight clearly signaled one-level-deep reference links (all verified to exist under references/) point to detailed endpoint docs.

Description

100%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.

The description is specific, trigger-rich, and answers both what and when explicitly in third-person voice. It is a strong, well-scoped description with minimal conflict risk.

DimensionReasoningScore

Specificity

Lists many concrete actions and data types — 'fetching stock prices (OHLCV), company fundamentals (income statement, balance sheet, cash flow), earnings, options data... calculating technical indicators (SMA, EMA, MACD, RSI, Bollinger Bands)' — with comprehensive coverage.

5 / 5

Completeness

Explicitly answers both 'what' ('Access real-time and historical stock market data...') and 'when' ('Use when fetching stock prices...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Comprehensive natural-language terms with synonyms and concrete keywords: 'stock prices, company fundamentals, earnings, options data, market news/sentiment, GDP, CPI, treasury yields, gold/silver/oil prices, Bitcoin/crypto prices, forex exchange rates' plus named indicators.

5 / 5

Distinctiveness Conflict Risk

Clearly niched to the Alpha Vantage API and financial market data with specific triggers (ticker fundamentals, GDP/CPI, forex/crypto prices), minimizing overlap with other skills.
