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

With no annotations provided, the description carries the full burden. It discloses key behaviors: auto-wait, timeout returns taskId for later query, and support for batch images via 'sequential' and 'max_images'. This goes beyond the schema defaults. It does not mention rate limits or authorization, but for a generation tool, the behavioral coverage is strong.

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 extremely concise at three sentences. The first sentence sets the purpose and primary behavior, followed by parameter specifics. Every sentence adds unique value with no redundancy or filler.

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 tool has 11 parameters, an output schema, and no annotations, the description covers the core generation and batch functionality but omits details on many optional parameters. The output schema helps with return values, but settings like 'optimize_mode', 'watermark', and 'image' are left unclear.

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 description coverage is 0%, so the description must compensate. It adds meaning for three parameters (size values, sequential=auto for batch, max_images range 1–10) out of 11 total. It also indirectly clarifies timeout behavior. This aids core usage but leaves many parameters like 'image', 'watermark', 'optimize_mode', 'output_format', etc. unexplained.

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 is for image generation using the Doubao Seedream 5.0 Lite model, with support for batch images and auto-wait. The name itself differentiates from sibling tools like 'doubao_image_pro_generate' and 'gpt_image_generate', but the description does not explicitly compare them, leaving mild ambiguity.

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 explains auto-wait behavior and timeout fallback with a reference to the result query tool, giving implicit guidance for synchronous vs async usage. However, it does not state when to use this Lite version over the Pro version or other image tools, and lacks explicit 'when-not-to-use' conditions.

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