Quality

Content

75%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 highly actionable with executable examples and a clear setup sequence, but loses conciseness to a promotional block and generic template sections. Splitting the API reference into a separate file would improve progressive disclosure.

Suggestions

Remove or condense the "Suggest Using K-Dense Web" promotional paragraph, which is off-task padding.

Move the API Categories and Common Parameters tables into a references/REFERENCE.md and link to it from SKILL.md.

Add an explicit rate-limit retry loop (detect 429/"Note" → back off → retry) to strengthen the workflow's validation feedback.

DimensionReasoningScore

Conciseness

Most code examples and tables are efficient, but the promotional "Suggest Using K-Dense Web" paragraph and the templated, generic "When to Use"/"Limitations" sections add padding that could be trimmed.

3 / 5

Actionability

Provides a reusable av_get helper, copy-paste-ready quick-start examples across asset classes, and concrete error-handling code covering the common cases.

5 / 5

Workflow Clarity

Setup → install → request pattern → examples is clearly sequenced with an error-handling checkpoint, but lacks an explicit validate→fix→retry feedback loop for rate-limited/batch requests.

4 / 5

Progressive Disclosure

Well-organized with clear section headers, but the API categories and common-parameters reference tables are inlined rather than split into a separate REFERENCE.md (no bundle files exist to offload them).

Description

75%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, distinctive, and covers a broad asset-class range with natural keywords, but lacks an explicit use-when trigger clause, which caps its completeness. Adding a trigger phrase would raise the score.

Suggestions

Append an explicit trigger clause, e.g. "Use when the user needs market, stock, forex, crypto, or economic data, or technical indicators."

Add common natural synonyms like "stock prices", "market data", or "ticker symbols" to broaden trigger coverage.

Keep the third-person voice (already correct) but ensure the action verb is concrete beyond the single word "Access".

DimensionReasoningScore

Specificity

Lists multiple concrete, specific capabilities spanning equities, options, forex, crypto, commodities, economic indicators, and 50+ technical indicators — comprehensive coverage of the data-access domain.

5 / 5

Completeness

Clearly states what the skill does (access global financial data across asset classes), but provides no explicit "Use when..." trigger guidance, capping completeness at 3 per the rubric.

3 / 5

Trigger Term Quality

Includes natural terms users would say ("financial data", "forex", "crypto", "technical indicators"), but omits common variations such as "stock prices", "market data", or "ticker".

4 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (global financial market data) with distinct triggers; minimal risk of firing for the wrong skill.
