Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The annotations already provide excellent behavioral information (read-only, non-destructive, idempotent, open-world). The description adds valuable context beyond annotations: it explains what happens when version_id is unspecified (uses latest), describes the ComfyUI path auto-mapping feature, and mentions authentication handling in generated commands. No contradiction with annotations exists.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is perfectly front-loaded with the core purpose in the first sentence. Each subsequent sentence adds essential information about default behavior, special parameter handling, and output format. There's zero wasted text - every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity, rich annotations covering safety and behavior, and the existence of an output schema (which means return values don't need explanation), the description is complete enough. It covers the tool's purpose, key parameter behaviors, and output characteristics while letting structured fields handle the rest.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description carries full burden for parameter semantics. It explains the purpose of version_id (defaults to latest if unspecified) and comfyui_path (auto-maps to correct ComfyUI directory). However, it doesn't explain model_id at all, leaving one of the three parameters undocumented in the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verbs ('Get download URLs', 'Generates ready-to-paste download commands') and resources ('for a model'). It distinguishes from sibling tools like 'get_download_url' by specifying additional functionality (curl/PowerShell commands, ComfyUI path mapping, authentication handling).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context about when to use this tool (to get download URLs with commands for a model) and includes some usage guidance ('If version_id not specified, uses latest version'). However, it doesn't explicitly state when NOT to use it or mention alternatives like 'get_download_url' from the sibling list, which appears to be a simpler version.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
