Single tool server with solid schema definition and comprehensive input validation. Tool naming follows verb-noun pattern (run_agent). Description is well-written and explains the purpose, behavior, and session management. Input schema is fully defined with all parameters typed and described. However, output schema is inferred from interface definitions rather than explicitly documented in the tool registration, and there is no documented error recovery guidance or examples of how session_id reuse works in practice. The tool accepts complex configuration (agent name, prompt, cwd, optional session_id) with good validation logic (max lengths, path traversal checks, format validation), which is above average for community servers.

• Add explicit output schema documentation to the tool definition: document all fields (result, session_id, agent, exit_code, execution_time, status, request_id, session_saved), their types, and what they signify.
• Document error codes and recovery paths: create a table mapping exit codes (124=timeout, 137=kill, 143=term, 8=max turns) to actionable guidance (e.g., 'Exit code 124: agent execution timed out. Try breaking the task into smaller steps or increasing timeout via cwd context.').
• Clarify session semantics: 'Sessions persist for 24 hours. A new session is created if session_id is omitted or expired. Each session is agent-specific; reusing a session from agent A with agent B will fail.' Add example showing multi-turn conversation flow.
• Implement confirmation pattern: add optional 'dry_run' boolean parameter (default false) so agent can preview execution plan before committing. Or add a separate 'preview_agent_plan' tool that returns what the agent would do without executing.
• Enhance agent parameter validation: catch common typos (e.g., levenshtein distance) and suggest nearest available agents. Or document that 'list_agents' resource must be called first to discover exact names.
• Add parameter examples in descriptions: 'cwd: /home/user/project (must be absolute path, no .. or null bytes)', 'session_id: abc123-def456 (alphanumeric, dash, underscore only)'.
• Document partial success scenarios: 'If status=partial, some steps succeeded but others failed. Check result field for details. You may retry the same session_id to continue from where it left off, or start a new session to restart.'
