Discovery
32%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 specific financial/trading niche (slippage) but remains too abstract and lacks explicit trigger guidance. It would benefit from concrete action verbs and a clear 'Use when...' clause to help Claude distinguish this skill from other trading-related skills.
Suggestions
Add a 'Use when...' clause with trigger terms like 'slippage tolerance', 'price impact', 'swap execution', 'DEX trades', or 'execution costs'
Replace abstract nouns with concrete actions: e.g., 'Calculates expected slippage, sets tolerance limits, recommends optimal trade sizes to minimize price impact'
Include common user phrases and variations: 'slippage settings', 'max slippage', 'price slippage', 'trading slippage protection'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (trade execution) and lists some actions (estimation, optimization, protection), but these are somewhat abstract and not fully concrete actions like 'calculate expected slippage' or 'set slippage tolerance limits'. | 2 / 3 |
Completeness | Describes what the skill does at a high level but completely lacks any 'Use when...' clause or explicit trigger guidance for when Claude should select this skill. | 1 / 3 |
Trigger Term Quality | Includes relevant terms like 'slippage', 'trade execution', and 'protection', but misses common variations users might say such as 'price impact', 'swap', 'DEX', 'trading fees', or 'execution price'. | 2 / 3 |
Distinctiveness Conflict Risk | 'Slippage' is a fairly specific term that narrows the domain, but 'trade execution' could overlap with general trading skills, order management, or market analysis skills without clearer boundaries. | 2 / 3 |

Implementation
79%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-written API reference with excellent actionability and conciseness - every code example is executable and the content respects Claude's intelligence. However, it lacks explicit multi-step workflows showing how to combine estimation, optimization, and protected execution in sequence, and the comprehensive content would benefit from being split across multiple files with clear navigation.
Suggestions
Add a 'Common Workflows' section showing complete sequences like: estimate slippage → check if acceptable → optimize if needed → execute with protection → verify actual slippage
Split the extensive API reference into separate files (e.g., ESTIMATION.md, OPTIMIZATION.md, PROTECTION.md) and keep SKILL.md as a concise overview with navigation links
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, presenting API references and commands without unnecessary explanation. It assumes Claude understands trading concepts and jumps directly to executable examples. | 3 / 3 |
Actionability | Provides fully executable TypeScript code examples that are copy-paste ready, with concrete chat commands and clear parameter specifications. Every section includes working code with realistic outputs. | 3 / 3 |
Workflow Clarity | While individual API methods are clear, there's no explicit workflow for common multi-step scenarios like 'estimate → optimize → execute with protection'. The protection section shows execution but lacks a complete workflow with validation checkpoints. | 2 / 3 |
Progressive Disclosure | Content is well-organized with clear sections, but it's a monolithic document with no references to external files for advanced topics. The extensive API reference could be split into separate files with the main skill providing an overview. | 2 / 3 |
