Quality

Content

71%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.

Highly actionable with strong executable examples and a useful error-handling loop, but it underuses its own bundle files — inlining endpoint tables instead of pointing to ENDPOINTS.md and never mentioning the production client script.

Suggestions

Replace the inlined 'API Endpoints Reference' tables with a brief summary and a link to references/ENDPOINTS.md to avoid duplication and reduce token load.

Add a section pointing to scripts/finnhub_client.py as the production-ready wrapper so Claude reaches for it instead of rewriting the boilerplate shown inline.

Tighten the opening paragraph and 'Free vs Premium' lists to the non-obvious facts, since the endpoint tables and pricing link already convey most of it.

DimensionReasoningScore

Conciseness

Mostly efficient code blocks, but the opening line restates the description and ~50 lines of endpoint tables are inlined even though references/ENDPOINTS.md already holds the full reference, so it could be tightened per the 3 anchor.

3 / 5

Actionability

Abundant copy-paste-ready executable Python covering quotes, candles, calendars, news, financials, WebSocket, and error handling, matching the 5 anchor for fully executable common-case examples.

5 / 5

Workflow Clarity

A simple API skill with a real feedback loop in error handling (429 -> sleep 60s -> retry), but no explicit sequenced workflow with validation checkpoints, sitting between the 4 and 5 anchors.

4 / 5

Progressive Disclosure

Has section structure, but the body inlines endpoint tables that duplicate references/ENDPOINTS.md and never references either bundle file (ENDPOINTS.md or scripts/finnhub_client.py), fitting the 3 anchor where content that should be separate is inline and references are not clearly signaled.

Description

92%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.

A strong, third-person description that clearly states capabilities and explicit usage triggers with concrete financial-data actions. Only minor gap is missing a few natural synonyms and ticker/extension variations users might say.

DimensionReasoningScore

Specificity

Lists multiple concrete actions across named domains: 'fetching real-time quotes, company profiles, financial statements, insider trading, earnings calendars, or market news' — comprehensive coverage matching the 5 anchor.

5 / 5

Completeness

Explicitly answers both 'what' ('FinnHub financial data API integration for stocks, forex, crypto, news, and fundamentals') and 'when' ('Use when fetching real-time quotes...') with concrete trigger phrases, matching the 5 anchor.

5 / 5

Trigger Term Quality

Good natural keywords (real-time quotes, company profiles, financial statements, earnings calendars, market news) but missing common synonyms and file extensions a user might say (e.g., 'stock price', 'ticker'), fitting the 4 anchor above the 3.

4 / 5

Distinctiveness Conflict Risk

Names FinnHub explicitly and scopes to a clear financial-data niche with distinct triggers, giving minimal conflict risk with other skills per the 5 anchor.
