generateVideoFromGeneratedImage

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

No annotations are present, and the description only mentions 'one-step process'. Important behavioral traits such as cost, async behavior, output format, and side effects are not disclosed. The description fails to compensate for the lack of annotations.

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 a single sentence, which is too brief given the tool's complexity (11 parameters). It is under-specified and does not effectively convey necessary information despite being concise.

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 description is minimal given the large parameter count and lack of output schema. It does not explain the overall workflow (e.g., whether the image is generated first or input is needed) or how the tool fits with siblings. Important context like return values and constraints is missing.

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 must explain parameters but does not. None of the 11 parameters are described in the description, and the schema itself lacks descriptions. The agent cannot understand what parameters like 'autoDownload' or 'personGeneration' do.

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 states the action (generate video) and the source (generated image). However, it does not differentiate from the sibling tool 'generateVideoFromImage', which could lead to confusion about when to use this tool vs that one.

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?

No guidance is provided on when to use this tool versus alternatives like generateVideoFromImage or generateVideoFromText. There is no explanation of prerequisites or exclusions.

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