86%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a well-structured, actionable skill that maps user requests to concrete code and offloads API detail to a real reference file. Its only weakness is minor redundancy and an implicit rather than explicit data-validation feedback loop in the main flow.
Suggestions
Remove the duplicated pip-install line from the Step 3 general pattern (keep it only in Step 1) and drop the valid periods/intervals table from SKILL.md since it already lives in api_reference.md.
Promote the empty-data/rate-limit handling into an explicit checkpoint in Step 3 (e.g., 'If the DataFrame is empty, check the ticker symbol and retry before presenting') rather than only mentioning try/except.
Tighten the Step 1 environment probe to a simpler check; the nested exec string is hard to read and could be a one-line import check.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly lean — uses a compact request-to-method mapping table, code blocks, and terse key rules rather than prose — but has minor redundancy (the pip install appears in both Step 1 and Step 3, and the valid periods/intervals table duplicates the reference file). Not a 5 because a few tokens could be trimmed without losing clarity. | 4 / 5 |
Actionability | Provides fully executable, copy-paste-ready code (install snippet, Ticker instantiation, try/except pattern) plus a precise mapping table from user request to the exact yfinance method, covering the common cases concretely. | 5 / 5 |
Workflow Clarity | Clear four-step sequence (ensure available → identify needs → write/execute → present) with a validation checkpoint in Step 1 (check for YFINANCE_NOT_INSTALLED before installing) and an explicit try/except rule, but lacks an explicit empty-data feedback loop in the main body (relegated to the reference), so it falls just below the top anchor. | 4 / 5 |
Progressive Disclosure | SKILL.md is a well-organized overview with clear sections that points to a single one-level-deep reference (`references/api_reference.md`, verified to exist) holding the bulk API detail, satisfying the clear-overview-with-well-signaled-references anchor. | 5 / 5 |
