88%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.
A high-quality, token-efficient MCP tool catalog: exact tool names, parameters, defaults, and symbology gotchas, organized into a clear 5-step workflow with explicit validation and error-retry feedback. The main shortfalls are the scarcity of worked example calls (only one) with some elided parameter lists, and the absence of any progressive-disclosure split despite an over-50-line body.
Suggestions
Add one short worked invocation per tool family in actionability (e.g. top_gainers('NASDAQ', '1D', 10), futures_top_movers('up', 'us', 10)) so every common case is copy-paste ready, mirroring the existing coin_analysis example.
Expand the elided parameter lists for stock_screener and backtest_strategy with the full signatures or a one-line note on where the client discovers them (deferred-tool schema), so no tool requires guessing parameters.
For progressive_disclosure, consider splitting the per-category tool tables (futures, options, backtesting, regional extras) into a one-level-deep references/tools.md file, keeping the routing table and normalize/validate steps in SKILL.md.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense with non-obvious operational facts Claude cannot know (tool names, parameter defaults like 'exchange defaults to KUCOIN', three coexisting symbologies, timeframe enums) and never explains concepts Claude already knows — RSI and MACD are named as capabilities, not tutorialized. Every token earns its place; it is not score 4 because there is no section of over-explanation to trim. | 5 / 5 |
Actionability | Concrete and mostly executable: exact tool names with parameter signatures ('coin_analysis(symbol, exchange, timeframe)', 'stock_prices(tickers)' with '"NASDAQ:NVDA,NYSE:DELL"' format), one worked example call ('coin_analysis("NVDA", "NASDAQ", "1D")'), and exact formats (expiry 'YYYY-MM-DD', timeframes '5m, 15m, 1h, 4h, 1D, 1W, 1M'). It falls between anchors: more complete than 'mostly executable with minor gaps' but only one literal example call exists and several parameter lists are elided ('stock_screener(country, stock_type, limit, …)'), so the copy-paste-ready coverage of every common case required for a 5 is not quite met. | 4 / 5 |
Workflow Clarity | Steps 1–5 are clearly sequenced (check requirements → select smallest useful tool set → normalize inputs → validate and interpret → respond) with explicit validation checkpoints: Step 4's 'Treat a returned error envelope as an error, not as an empty result. Use its retryability and symbol suggestions; retry at most once when marked retryable' is a concrete feedback loop, and Step 1 has failure handling for missing MCP tools. This is a read-only skill so the destructive-operation cap does not apply; it is not score 4 because validation and error-recovery checkpoints are explicit, not implicit. | 5 / 5 |
Progressive Disclosure | Good structure: well-organized section headers, per-category tool tables, and a decision table routing to the sibling skill, with no nested references (none exist — no references/, scripts/, or assets/ directories are bundled). It is not score 5 because the skill exceeds the under-50-lines simple-skill exception (~110 body lines) and the full 39-tool catalog is inlined in SKILL.md rather than split into a one-level-deep reference file; it is not score 3 because the inline placement is navigable and arguably appropriate for the modest total size (~9.5KB). | 4 / 5 |
