kbus server has 12 tools with complete input schemas and descriptions, but quality is inconsistent. Tool names follow verb_noun convention (kbus_send, kbus_spawn, kbus_terminate), which is good. However, descriptions are terse (avg ~60 chars, well below the 194-char baseline for A+ tools) and lack context about when to use each tool or what happens on failure. Parameters have types and descriptions, but many descriptions are minimal (e.g., 'Timeout in milliseconds' for kbus_wait). No output schemas are documented anywhere in the source. Error handling is absent, no guidance on retryability, recovery steps, or what errors mean. The contract-related tools (kbus_contract_bid, kbus_contract_award, etc.) form a coherent subsystem but lack inter-tool chaining documentation (e.g., does kbus_contract_award return a contract_id that kbus_contract_report needs?). Security: no evidence of permission gates, audit logging, or rate limiting despite tools like kbus_terminate and kbus_spawn being destructive. Overall, this reads like a functional but under-documented internal tool suite.

• Document output schemas for all tools. For kbus_agents, specify: returns array of {agent_id: string, role: string, status: string, registered_at: ISO8601}. For kbus_spawn, return {agent_id: string, role: string, created_at: ISO8601}. This enables LLM chaining.
• Expand descriptions to 100-200 chars with context. E.g., kbus_wait: 'Block until a message arrives for this agent. Returns immediately if a message is queued. Timeout (default from KBUS_WAIT_TIMEOUT_MS env) returns empty result, not an error. Idempotent: safe to retry.' This guides LLM behavior.
• Add confirmation/dry-run for destructive tools. kbus_terminate should accept a 'confirm' boolean parameter (default false). When false, return a preview of what would be terminated. When true, execute. Prevents accidental agent termination.
• Document contract tool chaining. Add to kbus_contract_announce: 'Returns commitment_id. Pass this to kbus_contract_bid, kbus_contract_award, and kbus_contract_report.' Add to kbus_contract_award: 'Returns contract_id (same as commitment_id). Use in kbus_contract_report to report completion.'
• Implement permission checks and audit logging. Gate kbus_terminate and kbus_spawn behind a 'caller_agent_id' parameter. Log all calls with timestamp, caller, tool, parameters, and result. Return 'Permission denied: agent X cannot terminate agent Y' with clear error text.
