aimux is a multiplexing gateway that exposes 6 tools for accessing remote MCP servers. Tool definitions are present with basic descriptions and input schemas, but fall short of production quality. Descriptions are minimal (10-50 chars), lack context on WHEN to use each tool, and omit error recovery guidance. Input schemas exist but are sparse: callTool and getPrompt accept generic 'object' types without field-level constraints. No output schemas documented. Tools lack error handling patterns, security guidance, and composition hints. The gateway pattern itself is sound, but the tool interface needs substantial refinement for LLM-safe operation.

• Document output schemas for all tools. E.g., listTools should return {tools: [{name: string, description: string, inputSchema: object}], total: number}. This enables LLMs to chain calls and extract IDs.
• Expand descriptions to 80-150 chars. For callTool: 'Invoke a tool from a multiplexed MCP server by name. Pass tool-specific arguments as an object. Returns the tool's result or an error with recovery hints.' Include WHEN to use it vs listTools.
• Replace generic 'arguments: object' with a schema that documents common argument patterns or references the upstream tool's schema. If that's not feasible, add a description: 'Arguments depend on the tool. Call listTools first to see each tool's input schema.'
• Add error handling to callTool response: on failure, return {error: string, recovery: string, availableTools: [string]}. E.g., 'Tool not found. Did you mean: [list]. Call listTools() to see all available tools.'
• Implement a confirm_callTool tool or add a 'dryRun' parameter to callTool for destructive operations. Agents should preview side effects before committing.
