Venice List Models

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

No annotations are provided, so the description carries the burden. It discloses that no authentication is needed (a useful behavioral fact) and that it returns capabilities + pricing. However, it doesn't disclose the response format (structured model list vs. prose), pagination/limits, or freshness of the catalog data.

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?

Three concise sentences, all carrying useful information: live catalog, capabilities+prices, and authentication status. Zero waste. Slightly repetitive between sentence one and two ('List the live model catalog' / 'Live catalog'), but otherwise tight.

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?

For a read-only listing tool with one optional filter parameter and no output schema, the description covers the essential purpose, the key output contents (capabilities + prices), and authentication requirements. It's adequate but could note whether results differ by filter type or whether pricing is current/rate-limited.

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?

The single parameter 'type' has a full enum (text, image, video, audio, etc.) in the schema, so the schema does most of the work. The description adds context that the catalog includes capability flags and pricing per model, which hints the filter parameter is about model category. With 0% schema description coverage, the description partially compensates by clarifying the overall meaning of catalog contents.

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?

States a specific verb+resource ('List the live model catalog') and adds scope details: capabilities, prices, USD pricing, no authentication needed. This clearly differentiates it from sibling generation/completion tools like venice_chat or venice_image_generate.

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 implies discovery/exploration use (listing a catalog), which is implicitly distinct from siblings that perform actions. It notes 'No authentication required', which signals accessibility. However, it doesn't explicitly state when NOT to use it or mention alternatives for other needs.

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