Discovery
40%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
The description identifies a highly specific trading niche but fails to explain concrete actions or provide trigger guidance. While distinctiveness is strong due to the unique platform combination, the lack of a 'Use when...' clause and missing action verbs significantly limit Claude's ability to know when to select this skill.
Suggestions
Add a 'Use when...' clause with trigger terms like 'arbitrage', 'Polymarket prices', 'prediction market divergence', or 'crypto price differences'
List specific actions such as 'identify price divergences', 'calculate arbitrage opportunities', 'monitor 15-minute candles', or 'compare spot vs prediction market prices'
Include common user phrases like 'find arbitrage', 'prediction market trading', or 'price discrepancies between exchanges'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (crypto trading) and a specific strategy (divergence trading between Spot and Polymarket), but doesn't list concrete actions like 'identify arbitrage opportunities', 'execute trades', or 'monitor price feeds'. | 2 / 3 |
Completeness | Describes what at a high level (divergence trading) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. | 1 / 3 |
Trigger Term Quality | Includes some relevant keywords ('Polymarket', 'crypto', 'trading', '15-minute') but misses common variations users might say like 'arbitrage', 'prediction markets', 'price differences', or 'crypto betting'. | 2 / 3 |
Distinctiveness Conflict Risk | Very specific niche combining Spot, Polymarket, divergence trading, and 15-minute timeframes - unlikely to conflict with other skills due to the unique combination of platform names and strategy. | 3 / 3 |
Total | 8 / 12 Passed |
Implementation
87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong, well-crafted skill that efficiently communicates a complex trading strategy. The command reference and threshold tables are excellent for actionability. The main weakness is the lack of explicit error handling or validation steps in the trading workflow, which is important for financial operations.
Suggestions
Add a validation/error handling section covering what to do when API calls fail, positions fail to close, or market data becomes stale beyond acceptable thresholds
Include explicit checkpoint for verifying position state after entry before monitoring for exit conditions
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations of what divergence trading is or how crypto markets work. Every section delivers actionable information without padding. | 3 / 3 |
Actionability | Provides concrete, copy-paste ready commands for all operations. The detection algorithm is specific with exact thresholds, and the threshold buckets table gives precise values Claude can use directly. | 3 / 3 |
Workflow Clarity | Exit logic is clearly sequenced with priority order, but the detection-to-trade workflow lacks explicit validation checkpoints. No feedback loop for error handling if API calls fail or if positions get stuck. | 2 / 3 |
Progressive Disclosure | Well-organized with clear sections progressing from quick start to detailed algorithm. Content is appropriately sized for a single file; no need for external references given the scope. | 3 / 3 |
Total | 11 / 12 Passed |
