B3.2/5.0

Behavior3/5

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

No annotations are provided, so the description carries the full disclosure burden, and it does at least characterize the async task model by stating the call returns a task id, status, and output URLs. It stops there – no mention of cost, failure behavior, or auth requirements, and the async/polling nature is only hinted at rather than explained.

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 no filler, and the core action is front-loaded ahead of the return-value note. It is appropriately sized, though the terseness contributes to the coverage gaps noted elsewhere.

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

Completeness3/5

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

For a 15-parameter generation tool with no annotations and no output schema, the description is thin: it briefly covers the return payload, which is genuinely useful without an output schema, but says nothing about the async lifecycle or how wait/timeout/callback interact. Adequate as a minimum but with clear gaps.

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 high at 87%, so the schema already documents most parameters, and the description adds no syntax, format, or interplay details beyond it. Baseline of 3 is appropriate when the schema does the heavy lifting and the prose adds nothing on top.

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 and resource ('Create a Grok Imagine task ... image to video') and names the underlying provider, so the agent knows it is an image-to-video generation call. It does not explicitly contrast with siblings like text_to_video or extend_video, but the '(image to video)' qualifier is enough to separate it from those without opening a schema.

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?

The description gives no when-to-use guidance and never names an alternative, even though siblings text_to_video and extend_video are obvious confusables. It also omits the prerequisite that a source image (URL or prior task id) must be supplied despite zero required parameters, leaving the agent to infer the workflow entirely from the schema.

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