Four tools with clear names and reasonable descriptions, but schemas lack depth and parameter documentation is sparse. xaip_list_servers and xaip_check_trust have empty input schemas ({}), which violates schema completeness. xaip_select has a well-structured input schema with enums and descriptions. xaip_report has good parameter coverage but lacks output schema documentation. Descriptions are adequate (100-150 chars) but could be more prescriptive about when to use each tool. No error handling guidance visible in descriptions.

• Document output schemas for all tools. E.g., xaip_list_servers should specify: returns array of {slug, trustLevel, executionCount, verdict}. xaip_check_trust should return {slug, trustLevel, executionCount, riskFlags}.
• Add error recovery guidance to descriptions. E.g., xaip_check_trust: 'If server not found, call xaip_list_servers to discover available servers.'
• Clarify xaip_report as a WRITE operation: 'This tool modifies the trust score database. Each call is signed and immutable. Use for reporting real execution results only.'
• Expand xaip_select mode guidance: 'Use relative (default) to pick the best available server even if below caution threshold. Use strict to reject all candidates below caution threshold, forcing fallback or user intervention.'
• Add pagination/limit guidance if xaip_list_servers can return many servers. E.g., 'Returns up to 100 servers. Use xaip_check_trust for detailed scores on specific servers.'
