Critical failure across all 53 tools. ZERO input schemas visible in source code, all tools declare Input: {} with no parameter definitions. Descriptions are present but generic and lack actionable detail (avg ~60 chars, well below 194-char baseline). No parameter descriptions, no output schemas documented, no error handling guidance. Tools are inferred from registration lists rather than explicit schema definitions. This server is non-functional for LLM integration.

• Define explicit JSON Schema for every tool's input parameters. Include 'type', 'description', 'required', and constraints (enum, minLength, pattern, minimum, maximum) for each parameter. Example: { 'type': 'object', 'properties': { 'session_id': { 'type': 'string', 'description': 'The unique session identifier (UUID format)' }, 'limit': { 'type': 'integer', 'minimum': 1, 'maximum': 100, 'default': 20 } }, 'required': ['session_id'] }
• Document output schemas for all tools. Specify the structure of returned objects, field types, and pagination info. Example: 'Returns an object with fields: { sessions: [{ id: string, name: string, status: enum(active|paused|closed), created_at: ISO8601 }], total_count: integer, next_cursor?: string }'
• Expand tool descriptions from ~60 chars to 100-200 chars. Include: (1) what the tool does, (2) when to use it vs. similar tools, (3) any prerequisites or dependencies. Example: 'Search indexed Codex sessions by keyword. Use this after lco_index_sessions to find sessions matching a query. Returns session IDs and metadata for further inspection with lco_describe_ref.'
• Add parameter descriptions to every tool. For tools with no visible parameters, clarify whether they accept no input or if the schema is incomplete. If parameters exist, document each one: type, valid values, constraints, and examples.
• Implement error handling guidance for WRITE operations (lco_drive, lco_codex_deliver, lco_codex_start_thread, lco_desktop_act). Document: (1) what errors can occur, (2) whether they are retryable, (3) what the agent should do next. Example: 'If thread creation fails with 'thread_already_exists', the thread is already running, call lco_codex_resume_thread instead.'
