Critical gaps across all dimensions. Only 5 tools total with minimal schema visibility. Tool names lack clear action verbs (blender.status, scene.summary, tools.categories.list are acceptable but generic). Descriptions are present but extremely brief (10-30 chars), well below the 50-200 char LLM-optimized baseline. Input schemas visible for only 2 of 5 tools; 3 tools (blender.status, scene.summary, tools.categories.list, object.create) have no visible parameter definitions in source. No output schemas documented. No parameter descriptions. No error handling guidance. No composition hints for multi-step workflows. The codebase shows sophisticated Rust architecture (workspace, schemars integration, rmcp framework) but tool definitions are not exposed in the provided source excerpts.

• Expand all tool descriptions to 50-200 characters. Include WHAT (action), WHEN (use case), and any prerequisites. E.g. 'Enable a tool category to make its tools available for use. Call tools.categories.list first to see available categories and their current status.'
• Add descriptions to all parameters. For tools.categories.enable, document: 'category (string): The category identifier to enable. Valid values: modeling, rendering, animation, scripting. Call tools.categories.list to discover available categories.'
• Document output schemas for all tools. Specify return type (object/array), required fields, and field types. E.g. blender.status should return {connected: boolean, version: string, capabilities: string[]}.
• Add error handling guidance. E.g. 'If category not found, returns error with available categories. If Blender is not running, returns connection_failed error, ensure Blender is started before retrying.'
• Implement tool annotations (readOnlyHint, destructiveHint, idempotentHint) for tools.categories.enable (destructive) and object.create (destructive) to signal side effects to agents.
