image_to_video

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the basic conversion without revealing any behavioral traits such as whether the operation is async, requires specific model support, or has output format/quality implications. This is severely lacking for a tool with no annotation support.

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, short sentence, which is easily readable and front-loaded. However, it is under-specified to the point of being unhelpful; the conciseness does not earn its place because it omits essential context about parameters and behavior.

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 apparent complexity (image-to-video generation), the lack of annotations and output schema, and the minimal description, the overall context is critically incomplete. The agent cannot determine input formats, output expectations, or how to handle the tool correctly.

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 two required parameters (image and prompt) but the schema provides no descriptions (0% coverage). The description does not mention either parameter, so the agent receives no guidance on what formats, meanings, or constraints apply to these fields.

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 uses the specific verb 'convert' and clearly identifies the resource being transformed (image) and the output (video). It is clear about the tool's core function, though it does not explicitly differentiate from sibling tools like generate_video or generate_image.

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 no guidance on when to use this tool versus alternatives such as generate_video or edit_image. There is no mention of prerequisites, intended use cases, or scenarios where a different tool would be more appropriate.

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