Agent readability score
Strengths
- Clear categorization of tools into 'FREE DISCOVERY', 'FREE QUALIFICATION', and 'FREE STATUS' phases.
Weaknesses
- Ambiguous tool names like 'crossingkey.describe' and 'capabilities.list' lack specificity.
- Parameter definitions are often vague (e.g., 'object' type in 'receipt.verify') and missing required/optional context.
- Multiple tools with similar purposes (e.g., 'list_capabilities' vs. 'capabilities.list') create ambiguity.
- No explicit error handling or constraint documentation in descriptions.
list_capabilities— Parameter 'access' lacks context on valid values or usage scenarios.crossingkey.describe— Name does not clearly indicate it provides service metadata.capabilities.list— Redundant with 'list_capabilities', causing potential tool selection confusion.receipt.verify— Parameter 'receipt' type is 'object' without schema details.
