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

No annotations are present, so the description carries full burden. It mentions the search-before-generation behavior and model restriction, but fails to disclose potential issues like search failure handling, rate limits, or any destructive aspects. Behavioral traits beyond the core function are lacking.

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?

The description is short and front-loaded with the core purpose. Every sentence is meaningful: first sentence states function and model restriction, second explains use case, and examples illustrate. Zero wasted words.

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?

Given the lack of output schema, the description adequately explains the tool's purpose and use case. It covers model restriction and parameter semantics. However, it could be more complete by describing the output format or what the generated image looks like.

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 100%, so parameters are well-documented. The description adds context for the prompt parameter (can include real-time requirements) and reiterates model restriction. However, it adds minimal new semantic value beyond the schema descriptions.

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?

The description clearly states the tool combines web search with text-to-image generation, specifying it's only for the 5.0 model. The verb 'generate image' and resource 'web search + text' are explicit, and it distinguishes from siblings by model version restriction.

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?

The description provides clear context for when to use (scenarios needing real-time info) and explicitly states it's exclusive to the 5.0 model. Examples are given but it does not explicitly mention when not to use or list alternatives among siblings.

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