93%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 content is a tight, well-structured overview: concise, copy-paste-ready commands for all five operations, a clear invoke/run/verify path, and appropriate delegation to the bundled client script. The only minor gap is the absence of an error-recovery loop, which is largely unnecessary for a read-only skill.
Suggestions
Add a one-line note in Pitfalls on what to do when a quote returns null fields (e.g. re-run with ALPHA_VANTAGE_KEY set) to close the small feedback-loop gap.
Consider noting expected JSON output shape for one non-quote command so Claude can validate responses without trial and error.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The ~75-line body is lean and assumes Claude's competence — "Read-only market data via Yahoo Finance", "All output is JSON on stdout", command one-liners — with no padding or explanation of concepts Claude already knows. | 5 / 5 |
Actionability | Fully executable copy-paste-ready commands are given in "Quick Reference" for every command, plus a concrete "How to Run" invocation and a "Verification" snippet that confirms a numeric `price` field. | 5 / 5 |
Workflow Clarity | This is a single-purpose read-only skill (no destructive/batch operations), so the simple-skill exception applies; the invoke→run→verify flow is clear with an explicit verification step, though there is no error-recovery feedback loop. | 4 / 5 |
Progressive Disclosure | The SKILL.md is a well-organized overview with clear sections (When to Use, How to Run, Quick Reference, Commands, Pitfalls, Verification) that delegates implementation to the bundled one-level-deep `scripts/stocks_client.py` — appropriate split for a small bundle. | 5 / 5 |
