Single tool with minimal definition quality. create_image has a basic description (16 chars, below 20-char threshold) and lacks parameter descriptions entirely. Input schema present but parameters undocumented. No output schema documented. No error handling guidance. Tool does not follow LLM-optimized description patterns. Naming is acceptable (verb_noun form) but insufficient to overcome missing descriptions and schemas.

• Expand tool description to 50-150 characters explaining WHAT (pulls/creates Docker image), WHEN (when you need to set up a container), and WHAT IT RETURNS (image name and status). Example: 'Pull and create a Docker image from a registry. Use this to prepare container images before running containers. Returns the image name and creation status.'
• Add descriptions to all parameters: name='Container/image name to assign', image='Docker image reference (e.g., ubuntu:22.04, nginx)', tag='Image tag to pull (defaults to latest if omitted)'.
• Document output schema in tool description or as a separate schema field: 'Returns {content: [{type: "text", text: JSON object with imageName (string) and status (string)}]}'.
• Add error handling: catch Docker API errors and return structured guidance. Example: 'Image pull failed: <reason>. Verify image exists in registry and credentials are valid. Try search_images() to find alternatives.'
• Add parameter constraints: mark 'image' as required (already done), document 'tag' format (alphanumeric + dots/dashes), and note that 'name' must be unique or will overwrite existing image.
