text_to_image

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

No annotations provided. Description omits behavioral details such as async nature, polling required, rate limits, or permission needs. Presence of 'wait', 'timeout_ms', 'poll_interval_ms' in schema implies async behavior but description does not clarify.

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?

Single sentence, front-loaded with purpose. No wasted words, but could be slightly more structured. Fails to earn its place by omitting crucial context.

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 5 parameters (0 required), no output schema, and multiple sibling tools, description is insufficient. Does not explain async task lifecycle, parameter usage, or differentiation from similar tools.

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 (40% – only wait and model have descriptions). Description adds no parameter-level information beyond enumerating return values (task id, status, output URLs).

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 the action ('Create'), the specific resource ('Grok Imagine task'), and the domain ('text to image'). It differentiates from siblings like edit_image or text_to_video by specifying the modality.

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 alternatives like edit_image or text_to_video. No mention of prerequisites or context for invocation.

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