Quality

Content

100%

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

A well-constructed skill body: lean and executable, with a clear setup sequence, explicit error checks, and a clean one-level-deep reference structure. The only minor gaps are a dated rate-limit figure and the absence of a 429 retry loop for batch use.

DimensionReasoningScore

Conciseness

The body is lean — mostly executable code, a helper function, and dense tables — and assumes Claude knows the financial concepts (no 'what is RSI' padding), matching the 'lean and efficient; every token earns its place' anchor. A minor blemish is the time-sensitive 'Free tier: 25 requests/day (as of 2026)', but it is a single parenthetical rather than a defining feature.

3 / 3

Actionability

Provides copy-paste-ready, fully executable guidance: an `av_get` helper, quick-start calls with parsed response keys, install/export commands, and concrete error-checking code, matching the 'fully executable code/commands; copy-paste ready' anchor.

3 / 3

Workflow Clarity

Setup is numbered and sequenced (get key -> export env var -> install -> call -> handle errors) and error checks for 'Error Message', 'Note', and 'Information' are explicit; as a single-action read-only API skill the action is unambiguous per the simple-skills note. A 429 retry loop for the mentioned batch use would strengthen it but the operations are non-destructive, so no cap applies.

3 / 3

Progressive Disclosure

A clear overview (quick-start, categories table, common params) points via a dedicated 'Reference Files' section to eight one-level-deep reference files, all of which exist in references/ and match the linked paths — matching the 'clear overview with well-signaled one-level-deep references' anchor.

Description

100%

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, comprehensive description: it states concrete capabilities, provides an explicit 'Use when' trigger clause with natural user terms, and occupies a distinct financial-data niche. Minor verbosity in the capability enumeration, but every clause earns its place.

DimensionReasoningScore

Specificity

Enumerates many concrete actions — 'fetching stock prices (OHLCV), company fundamentals (income statement, balance sheet, cash flow), earnings, options data... calculating technical indicators (SMA, EMA, MACD, RSI, Bollinger Bands)' — matching the 'lists multiple specific concrete actions' anchor rather than the domain-only level 2.

3 / 3

Completeness

Explicitly answers both what ('Access real-time and historical stock market data...') and when via a clear 'Use when fetching...' clause, satisfying the level 3 anchor; not capped at 2 because the trigger guidance is present and in third person.

3 / 3

Trigger Term Quality

Dense coverage of natural terms a user would say — 'stock prices', 'earnings', 'GDP, CPI, treasury yields', 'gold/silver/oil prices', 'Bitcoin/crypto prices', 'forex exchange rates' — going well beyond the 'some relevant keywords' level 2 anchor.

3 / 3

Distinctiveness Conflict Risk

Scoped to a clear niche — financial market data via the Alpha Vantage API — with distinctive triggers (OHLCV, treasury yields, insider transactions) unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers' anchor.
