85%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.
An exemplary lean, executable SKILL.md: concrete commands, honest pitfalls, and a verification step, with the bundle correctly wired. The two real defects are the Quick Reference/Commands redundancy and an incorrect multi-symbol crypto example that would error against the actual script.
Suggestions
Fix the crypto documentation: the script accepts one symbol per call, so change "crypto SYMBOL [SYMBOL2 ...]" and "python $SCRIPT crypto BTC ETH SOL" to single-symbol usage (e.g. "crypto BTC") and mention the --vs option.
Merge the Quick Reference code block into the Commands section (or replace per-command prose with the annotated block) to remove the duplicated invocation examples.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence — no explanations of what stocks or APIs are, every section (When to Use, Prerequisites, Commands, Pitfalls, Verification) earns its place. It sits at 4 rather than 5 because the "Quick Reference" code block substantially duplicates the "Commands" section that immediately follows it, a small redundancy that could be trimmed. | 4 / 5 |
Actionability | Guidance is copy-paste ready: a full script path invocation ("python $SCRIPT quote AAPL"), per-command syntax, expected JSON output, and a concrete verification command — matching anchor 5. It drops to 4 because one documented example is wrong: the body shows "crypto SYMBOL [SYMBOL2 ...]" and "python $SCRIPT crypto BTC ETH SOL", but the bundled script's crypto subcommand accepts a single symbol (argparse rejects extra positionals), so that example fails as written. | 4 / 5 |
Workflow Clarity | This is a simple, single-action, read-only skill and the invocation is unambiguous, so the simple-skill exception applies. The "Verification" section gives an explicit expected outcome ("a JSON object with symbol: \"AAPL\" and a numeric price field") and the Pitfalls section provides error-recovery guidance (rate-limit delays, null crumb fields backfilled via ALPHA_VANTAGE_KEY), so it does not fall to 4 on missing checkpoints. | 5 / 5 |
Progressive Disclosure | The bundle is a single script (scripts/stocks_client.py) and every reference to it in the body resolves to that real file, one level deep. The body is ~80 well-organized lines with clear section headers and no content that belongs in a separate reference file — a 5-command CLI doc is appropriately inline, matching the well-organized-sections standard for skills needing no external references. | 5 / 5 |
