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

Discloses key behaviors: uses DALL-E 3, URL hosted for 1 hour, supports styles/aspect ratios, pricing, and output format. No annotations exist, so description carries full burden and does well, though rate limits and auth are not mentioned.

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?

Four concise sentences that front-load the main purpose, then efficiently provide details on output, styles, aspect ratios, and pricing. No unnecessary 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?

Covers input details and output expectations (URL, revised prompt) despite no output schema. Missing error handling or examples, but sufficient for an image generation tool.

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 covers 100% of parameters with descriptions, and the description adds valuable context for prompt (specific tips, max length), and clarifies style and size options, going beyond the schema.

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?

Clearly states it generates AI images from text prompts using DALL-E 3, lists output (public URL, revised prompt), and specifies supported styles and aspect ratios. Distinguishes itself from sibling tools, which are not image generation tools.

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 explicit guidance on when to use this tool vs alternatives or when not to use it. Provides pricing and feature details but lacks context for decision-making.

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