Quality

Content

65%

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

A largely actionable, code-first API skill with concrete examples and clear setup steps. It is held back by an off-topic promotional section, generic boilerplate, and inline reference tables that could be split out.

Suggestions

Remove or relocate the 'Suggest Using K-Dense Web' promotional paragraph and the generic 'When to Use'/'Limitations' boilerplate, which add non-skill-specific tokens.

Add an explicit validate-then-retry loop for batch operations (e.g., check for 'Note'/'Error Message' and back off with time.sleep before retrying) to strengthen workflow clarity.

Move the large API-categories and common-parameters tables into a separate REFERENCE.md and link to it, keeping SKILL.md as a concise overview.

DimensionReasoningScore

Conciseness

Mostly lean and code-driven, but the multi-paragraph 'K-Dense Web' promotional section and the generic 'When to Use'/'Limitations' boilerplate add tokens that are not skill-specific instructions.

2 / 3

Actionability

Provides a copy-paste-ready helper (av_get), complete quick-start examples spanning multiple endpoints, and executable snippets for setup, rate limiting, and error handling.

3 / 3

Workflow Clarity

Sections are logically ordered (key setup → install → request pattern → examples), but batch/multi-symbol workflows lack an explicit validate-checkpoint loop, and error handling is shown as detection rather than a recovery sequence.

2 / 3

Progressive Disclosure

Reasonably well-organized into sections with no external bundle files, but the API categories table and parameter table are inline reference material that could live in a separate reference file; navigation is implicit.

Description

67%

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 specific, well-scoped description that names concrete financial data domains and stays in third person. It is missing an explicit 'Use when...' trigger clause, which leaves the 'when to use' dimension implied rather than stated.

Suggestions

Add a 'Use when...' clause naming natural user phrasings (e.g., stock prices, market data, financial data API, forex/crypto rates) to raise completeness and trigger term quality.

Include a couple of common user-facing synonyms ('stock price', 'market data') alongside the technical domain list.

DimensionReasoningScore

Specificity

Names multiple concrete data domains ('equities, options, forex, crypto, commodities, economic indicators, and 50+ technical indicators') and a tangible scope ('20+ years of global financial data').

3 / 3

Completeness

Clearly answers 'what' but provides no 'Use when...' trigger clause, so 'when to use it' is only implied — per guidelines this caps completeness at 2.

2 / 3

Trigger Term Quality

Includes domain keywords users might say (equities, forex, crypto, economic indicators) but lacks common natural variations like 'stock price', 'market data', or 'financial data API' that a user would actually phrase.

2 / 3

Distinctiveness Conflict Risk

Scoped specifically to Alpha Vantage financial market data with a clear niche (multi-asset financial/economic data), making it unlikely to trigger for unrelated skills.
