ConferLLM defines 4 tools with mixed quality. Tool names follow verb_noun conventions (create_chat, continue_chat, list_sessions) and descriptions exist for all tools. However, critical gaps undermine overall quality: (1) Parameter descriptions are sparse or absent in key tools, create_chat and continue_chat lack descriptions for 'images' and 'image_output_dir' parameters; (2) No output schemas are documented for any tool, making it impossible for LLMs to plan downstream operations; (3) Error handling is not visible in the tool definitions, no guidance on retryability, user-fixable errors, or recovery paths; (4) Security concerns: the 'include_raw_response' parameter suggests raw model output is returned, which may contain tokens or internal details; (5) The 'chat' tool is marked as deprecated in its description but still actively exposed, creating ambiguity; (6) No input validation, enums, or constraints documented (e.g., 'images' array has no min/max length, model names have no constraints). Tool descriptions are present (100+ chars each) and address WHAT and WHEN, but lack specific guidance on WHICH parameters are required in edge cases (e.g., model vs session_id mutual exclusivity in 'chat' is documented but not enforced via schema constraints). Schemas visible in source show basic types (string, array, boolean) but lack required field declarations, pattern constraints, and detailed field descriptions.

• Add complete output schemas for all tools. Example for create_chat: document that it returns {session_id: string, model: string, message: string, created_at: ISO8601}. Required for LLM to chain tools.
• Add 'required' array to each tool schema. For create_chat: make 'message' and 'model' required, make others optional.
• Add enum constraint to 'model' parameter (e.g. enum: ['gpt-4', 'gpt-3.5-turbo', 'claude-3-sonnet', ...]) or document how to discover valid model names.
• Add minLength/maxLength constraints: 'message' should have minLength: 1, maxLength: 8000 or similar. Document limits in parameter description.
• Add minItems/maxItems to 'images' array. Example: minItems: 0, maxItems: 10 with description 'Up to 10 images per request.'
• Document what 'include_raw_response' includes and sanitization applied. Does it leak API keys? Internal model state? Consider removing or renaming to 'include_debug_info' with clear security warnings.
• Mark 'chat' tool as deprecated in tool registration (if MCP supports deprecation flag) or remove it entirely. Consolidate into create_chat/continue_chat.
• Add error handling documentation in tool descriptions. Example: 'Returns error if model not found (retryable) or if rate limited (retry with exponential backoff, max 3x).'
• Add parameter descriptions to schema for 'images' and 'image_output_dir'. Schema descriptions should include format expectations, not just tool description.
• For list_sessions, document the return schema. Does it return [{name, id, model, created_at, last_message_at}, ...]? What pagination support exists?

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