This server implements 7 terminal session management tools with adequate naming and descriptions, but has several quality gaps that prevent a higher score. Tool names follow verb_noun conventions (session_create, session_execute, session_send, session_interrupt, session_close, session_list, file_create), which is good. Descriptions are generally present and contextual (e.g., session_execute explicitly distinguishes itself from session_send with use-case guidance). However, input schemas lack formal constraint documentation (no enums for mode parameters, no explicit min/max for numeric parameters like timeout and max_lines), and output schemas are not formally documented. Error handling is minimal, tools return success/error dicts but lack actionable recovery guidance. Parameters like 'timeout' and 'max_lines' have reasonable defaults but no documented constraints (timeout defaults to 30 with no stated range; max_lines defaults to 10 with no explicit upper bound). The file_create tool accepts an optional 'mode' parameter but does not enumerate valid values. Security risks exist: no permission gate on destructive operations (session_close is unprotected), and no audit/logging pattern visible in the tool definitions themselves.

• Add formal output schema documentation to all 7 tools. For each tool, explicitly define the response object structure (fields, types, descriptions) so LLMs know what to expect.
• Implement a confirmation pattern for session_close: add a 'confirm' parameter (boolean, default false) or a separate 'session_close_confirm' tool that requires explicit user/agent consent before destruction.
• Add numeric constraints to parameters: timeout (min 1, max 300 suggested for terminal execution); max_lines (min 1, max 1000 or reasonable limit); file_create mode as an enum ('755', '644', '600', '700', etc.) or pattern (^[0-7]{3}$).
• Enrich error responses with recovery guidance. E.g., session_execute when session not found: 'Session name=<name> not found. Use session_list to see active sessions, or session_create to create a new one.'
• Expand session_close description to at least 50 characters explaining side effects: 'Terminate a session and free all associated processes and file handles. Irreversible.'
• Add pagination guidance to session_list: document expected response structure (array of session objects) and consider adding optional 'limit' and 'offset' parameters for future scalability.
• Add idempotency guidance: session_create should document whether calling it twice with the same name overwrites or returns error; session_execute should note it's inherently non-idempotent.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
