Agent-rack defines 8 tools with basic schemas and descriptions, but falls short of production quality. All tools have descriptions (10-80 chars, mostly adequate) and input schemas with type definitions. However, parameter descriptions are sparse or missing context. Tool names follow verb_noun convention (agent_run, agent_list, agent_session_*) but lack clarity on distinctions, e.g., agent_session_send vs agent_run both interact with agents. Output schemas are not documented. Error handling is minimal; no recovery guidance or actionable error messages visible. No tool annotations (readOnlyHint/destructiveHint) despite clear risk classifications in metadata. Composition is reasonable (single responsibility per tool), but chaining support is unclear, responses don't document what IDs/references they return for downstream calls.

• Document output schemas for all tools. Specify field names, types, and which IDs/references are returned for chaining. E.g., agent_session_list should return [{sessionId, agentId, status, createdAt, ...}].
• Add enum constraints to parameters with known valid values. E.g., agent_review.focusAreas should list valid areas (e.g., ['performance', 'security', 'readability', 'testing']). Replace free-form strings with enums.
• Add tool annotations to all tools. Mark agent_session_cancel with destructiveHint=true; mark agent_run and agent_session_send with idempotentHint=false (or true if they are idempotent); mark read-only tools with readOnlyHint=true.
• Clarify the distinction between agent_run (new session?) and agent_session_send (existing session?). Rename one or add explicit documentation. Consider merging if they serve the same purpose.
• Add error recovery guidance to parameter descriptions. E.g., 'sessionId (string): The session ID to query. If unknown, call agent_session_list first to discover valid IDs.'
