generate_video

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

With no annotations, the description must disclose behavioral traits. It only mentions generating video and returning URLs, omitting crucial details like generation time, rate limits, auth requirements, or that it uses Grok's endpoint.

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?

Very concise at 15 words, but sacrifices critical information. The single sentence is front-loaded but insufficient for a tool with 16 parameters and no annotations.

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?

Tool has 16 parameters, no output schema, and no annotations. Description fails to explain return format, authentication (account/cookies), or common failure modes. Completely inadequate for an AI agent to use 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?

Schema coverage is low (31%), yet description adds no parameter-level context beyond what the schema already provides. Key parameters (prompt, mode, extra) are not explained in the description, leaving the agent to infer usage.

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?

Description clearly states 'Generate video through the working Grok media endpoint and return parsed video URLs.' This specifies the action (generate), resource (video), and distinguishes from siblings like generate_image and image_to_video.

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 on when to use this tool versus siblings like image_to_video, upscale_video, or generate_image. Lacks context about prerequisites (e.g., needing account/cookies) or scenarios where this is preferred.

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