generateVideoFromImage

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

No annotations are provided, and the description only states the basic operation. It does not disclose any behavioral traits such as processing time, image format requirements, or potential limitations, leaving the agent without important context.

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 under-specified for a tool with 10 parameters. It lacks structure and important details, making it minimally informative.

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 complexity (10 parameters, no output schema, no annotations), the description is grossly incomplete. It fails to provide context for the output, parameter behavior, or usage scenarios.

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 input schema has zero description coverage for parameters, and the description adds no meaning about any of the 10 parameters. Parameters like 'prompt', 'aspectRatio', 'durationSeconds' are not explained, so the agent cannot infer their purpose from 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 generates a video from an image, using a specific verb and resource. However, it does not differentiate from sibling tool 'generateVideoFromGeneratedImage', which has a similar purpose.

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 usage when you have an image to convert to a video, but provides no explicit guidance on when to use this tool versus alternatives like 'generateVideoFromText' or 'generateVideoFromGeneratedImage'. No exclusions or context are given.

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