Quality
Discovery
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.
This is an excellent skill description that covers all evaluation dimensions strongly. It provides comprehensive specific capabilities, extensive natural trigger terms spanning multiple financial domains, explicit 'Use when' guidance, and a distinctive identity tied to Yahoo Finance with enumerated commands. The description is thorough without being padded with fluff.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: stock/bond prices, credit analysis, macro dashboard, FX rates, ETF flows, fundamentals, news, options chains, dividend history, analyst ratings. Also enumerates specific commands (yf price, yf quote, etc.). | 3 / 3 |
Completeness | Clearly answers both 'what' (financial data from Yahoo Finance covering stocks, bonds, credit, macro, FX, ETFs, fundamentals, news) and 'when' with an explicit 'Use when the user asks about...' clause listing comprehensive trigger scenarios. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'stock prices', 'bond yields', 'credit metrics', 'leverage ratios', 'debt/ebitda', 'interest coverage', 'VIX', 'DXY', 'treasury yields', 'income statements', 'balance sheets', 'cash flow', 'options chains', 'dividend history', 'analyst ratings/upgrades', plus specific currency codes and asset names. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear niche: Yahoo Finance data specifically, with unique command prefixes (yf price, yf macro, etc.) and specific domain focus on financial market data. Unlikely to conflict with other skills. | 3 / 3 |

Implementation
79%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-crafted CLI reference skill that is concise, actionable, and well-structured with a clear command table and usage examples. Its main weaknesses are the lack of explicit validation/error-recovery workflows and the absence of supporting reference files for detailed output schemas or advanced usage patterns. Overall it serves its purpose effectively as a quick-reference guide.
Suggestions
Add example output (or output schema) for key commands like `yf credit` and `yf macro` so Claude knows what fields to expect and can interpret results correctly.
Consider adding a brief troubleshooting section with specific error messages and recovery steps instead of the vague 'wait a moment and retry' guidance.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. It uses a table for command reference, avoids explaining what Yahoo Finance is or how CLI tools work, and every section earns its place. The 'When to Use Which Command' section adds genuine workflow value without padding. | 3 / 3 |
Actionability | Every command is shown with concrete, copy-paste-ready examples. The table format provides exact syntax patterns, and the setup section gives the specific chmod command needed. The --json flag is clearly documented for programmatic use. | 3 / 3 |
Workflow Clarity | The 'When to Use Which Command' section provides useful workflow sequences (e.g., 'yf quote → yf fundamentals → yf history' for deep dives), but there are no validation checkpoints or error recovery feedback loops. For a CLI data-fetching tool this is less critical than for destructive operations, but the error handling section is vague ('wait a moment and retry' without specifics). | 2 / 3 |
Progressive Disclosure | The content is well-organized with clear sections and a reference table, but everything is in a single file. No bundle files are provided, so there's no external reference structure. For a skill of this size (~60 lines) this is borderline acceptable, but the fundamentals/credit commands could benefit from separate detailed reference docs showing output schemas or field definitions. | 2 / 3 |
