A3.6/5.0

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 burden. It reveals that a task is created and that the return includes a task id, status, and output URLs, hinting at asynchronous execution. However, it omits cost/quota implications, reference-unit consumption, the effect of the wait flag, and whether output URLs are durable, leaving partial transparency.

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

Conciseness5/5

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

A single two-clause sentence that efficiently captures purpose, modality, and return contract with no filler. 'On RunAPI' and 'Returns a task id, status, and output URLs' both add value beyond the tool name and schema. It is short and front-loaded.

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?

This tool has 16 parameters with intricate constraints (mutual exclusion of first-frame image, shared seven-unit reference limits, clip timing rules, webhooks, and polling), yet the description only covers a trivial text-to-video case. It also does not mention that the returned task id should be consumed by get_task. With no output schema and no annotations, this description is too thin for safe invocation of the tool's advanced modes.

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?

The description itself adds no parameter-level meaning. Schema description coverage is 88%, which sets the baseline at 3; the schema does the heavy lifting for parameters. The description does not compensate for the two undocumented parameters (timeout_ms, poll_interval_ms), but it does not need to given the high schema coverage.

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

Purpose5/5

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

States a specific verb ('Create'), resource ('Gemini Omni task on RunAPI'), and domain ('text to video'), which clearly distinguishes it from sibling tools like create_audio and create_character. The mention of RunAPI and Gemini Omni goes beyond the tool name, so the purpose is unambiguous.

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

Usage Guidelines3/5

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

No explicit when-to-use or when-not-to-use guidance. The description only implies that this tool is for generating video from a text prompt and does not mention that get_task is the companion for polling or that create_character/create_audio are alternatives for other modalities. This is implied usage, not active routing.

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