B3.1/5.0

Behavior3/5

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

With no annotations, the description carries the full burden, but it does disclose that this is an asynchronous task-creation call returning a task id, status, and output URLs. It says nothing about authentication, cost, rate limits, failure behavior, or what the 'wait' polling default implies; for a 23-parameter generation tool with zero annotation coverage this is only partially adequate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences with the verb and resource front-loaded and the return shape compactly stated; nothing is wasted. It is arguably under-specified for the tool's complexity, but that is a completeness concern rather than a verbosity one.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a task with 23 parameters, no required fields, no annotations, and no output schema, the description leaves major gaps: which image fields to supply, how model/ratio/duration interact, and what the polling behavior actually does. The return-value sentence is the only substantive addition, and it is not enough.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is reported at 91%, so the baseline is 3 even though the description adds no parameter-level meaning. In practice most schema entries are placeholders ('Declared type: integer'), so the description does nothing to explain key knobs like first_frame_image_url, last_frame_image_url, ratio, or wait.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (create) and resource (a Wan image-to-video task on RunAPI), and the parenthetical 'image to video' distinguishes it from text_to_video, edit_video, and speech_to_video siblings. However, it never clarifies which input fields constitute the 'image' input, which matters given the tool has zero required parameters.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance, no conditions, and no mention of alternatives such as text_to_video or animate, despite several closely related siblings. The agent must infer selection purely from the tool name.

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