Single tool 'opensim_execute_command' has a basic schema with command and arguments parameters, but lacks critical quality markers. Description is present (67 chars) but generic and does not explain when/why to use the tool or what it returns. No output schema documented. Parameters lack detailed descriptions explaining constraints, formats, or valid values. No error handling guidance. No tool annotations. The tool accepts arbitrary command strings, creating injection risks without validation guidance.

• Add a detailed output schema documenting what fields the tool returns (e.g., status, output, error_message, exit_code). Include example response structure.
• Expand tool description to 100-150 chars explaining: 'Executes OpenSimulator console commands. Returns command output and status. Use for administrative tasks like region management, user operations, or system queries. Requires valid OpenSim console credentials.'
• Add parameter descriptions: 'command' → 'The OpenSimulator console command name (e.g., "show regions", "create user"). Must be a valid command from the loaded help catalog.'; 'arguments' → 'Array of command arguments as strings. Order matters. Example: ["FirstName", "LastName", "password"] for create user.'
• Document error cases and recovery: 'If command is invalid, returns error_message with available commands. If authentication fails, returns 401 error, verify OPENSIM_CONSOLE_USER and OPENSIM_CONSOLE_PASS.'
• Add tool annotations in schema: set destructiveHint=true for commands that modify state (create, delete, set), idempotentHint=false for non-idempotent commands, readOnlyHint=true for query commands (show, list).
