create_gradient_animation

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

There are no annotations, so the description carries the full burden of behavioral disclosure. It indicates that a video is generated but does not mention output format, destination, side effects, or whether the operation is reversible. This is minimal behavioral coverage.

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 with the core action front-loaded and no filler. 'Animated moving' is slightly redundant, but overall it is appropriately 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?

With no output schema and no annotations, the description leaves return values, output file handling, and relationship to sibling generation tools unspecified. An agent can invoke it with defaults, but the surrounding behavior is not fully described.

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 description adds no information about width, height, or duration, and the schema has 0% description coverage. The parameter names are self-explanatory at a basic level, but units (e.g., seconds for duration) and value constraints are left unstated.

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 a specific action ('Generate') and a concrete deliverable ('animated moving gradient video'), making the tool's core purpose clear. It distinguishes the resource type by mentioning 'gradient,' though it does not actively contrast itself with similar animation-creation siblings.

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 about when to use this tool instead of create_custom_animation, create_animated_scene, or other animation tools. The description implies a use case but offers no prerequisites, exclusions, or alternative routing.

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