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

With empty annotations, the description notes it is 'Intelligence only' and 'no direct model API resale,' which signals that it will not execute model generation. It does not disclose potential side effects, rate limits, or the exact meaning of 'live,' leaving behavioral expectations partially unspecified.

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 compact: two sentences covering scope and constraints. The model list is informative without being redundant, and every phrase contributes to understanding the tool's purpose.

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?

The tool has no output schema and empty annotations, so the description must convey what to expect. It covers the input domain and content types, but the nature of the response ('intelligence') is vague, and no details are given about the data source or response format.

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?

Since the schema provides no parameter descriptions, the description's enumeration of models (Wan, VACE, LTX) and topics (settings, comparisons, gotchas) helps infer that the 'model' parameter likely accepts one of these names and 'query' requests particular intelligence. However, the relationship between the two optional parameters and their accepted formats remains ambiguous.

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 identifies the tool's domain (generative video/image workflow intelligence) and lists specific models, distinguishing it from broader sibling tools. However, it lacks an explicit action verb like 'get' or 'query', relying on the noun 'intelligence' to convey the function.

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 the tool should be used when needing intelligence on the listed generative video/image models, but it does not provide explicit when-to-use or when-not-to-use guidance, nor does it reference alternative tools. The 'no direct model API resale' note hints at a limitation but does not guide tool selection.

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