Discovery
22%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This description is essentially just a product tagline rather than a functional skill description. It identifies the domain (a DEX on Arbitrum) but completely fails to explain what actions Claude can perform or when this skill should be selected. Without any capability descriptions or trigger guidance, Claude cannot effectively choose this skill from a library.
Suggestions
Add specific actions Claude can perform, e.g., 'Place limit orders, check orderbook depth, view trading pairs, analyze liquidity'
Include a 'Use when...' clause with trigger terms like 'trade on Lighter', 'Arbitrum DEX', 'orderbook trading', 'limit orders on Arbitrum'
Expand trigger terms to include common user phrases like 'swap tokens', 'check prices', 'DeFi trading', 'crypto exchange'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only names the product and platform ('Orderbook DEX on Arbitrum') but provides no concrete actions. It doesn't describe what Claude can actually do with this skill. | 1 / 3 |
Completeness | Missing both 'what does this do' (no actions described) and 'when should Claude use it' (no 'Use when...' clause or equivalent guidance). Only identifies the domain. | 1 / 3 |
Trigger Term Quality | Contains some relevant keywords ('Orderbook', 'DEX', 'Arbitrum') that users familiar with DeFi might use, but lacks common variations like 'decentralized exchange', 'trading', 'swap', or 'crypto'. | 2 / 3 |
Distinctiveness Conflict Risk | The specific product name 'Lighter' and 'Arbitrum' provide some distinctiveness, but 'Orderbook DEX' is generic enough to potentially conflict with other DEX-related skills. | 2 / 3 |
Total | 6 / 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 well-crafted, concise skill that efficiently documents a trading CLI. The command reference is clear and actionable with good examples. The main weakness is the absence of validation steps for financial operations—users should verify positions after trades and understand error handling for failed transactions.
Suggestions
Add a brief workflow showing trade verification: e.g., '/lighter long ETH-USD 1' followed by '/lighter positions' to confirm execution
Include guidance on what to do if a transaction fails or an order doesn't fill (check orders, retry, etc.)
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations of what a DEX is or how orderbooks work. Every line provides actionable information Claude needs. | 3 / 3 |
Actionability | Fully concrete with copy-paste ready commands. Clear examples showing both market and limit orders, with specific syntax patterns for all operations. | 3 / 3 |
Workflow Clarity | Commands are well-organized by category, but lacks validation checkpoints for trading operations. No guidance on verifying order execution, checking position status after trades, or handling failed transactions. | 2 / 3 |
Progressive Disclosure | Appropriate structure for a simple skill. Quick start gets users going immediately, commands are organized in logical tables, and external resources are clearly linked for deeper exploration. | 3 / 3 |
