generate_image

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

The annotations already indicate destructiveHint=true, so the description's mention of generating images adds minor behavioral insight. It identifies three different providers but lacks details on potential side effects (e.g., cost, latency) or error handling. This is adequate but not comprehensive.

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 concise (two sentences) and front-loaded with the core purpose. However, the second sentence is a tip that could be better integrated, and the structure lacks clear separation of purpose and usage notes.

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's complexity (9 parameters, three providers, no output schema), the description is lacking. It does not explain the return format, how to handle different providers, or provide complete guidance for using parameters. The tip is helpful but insufficient for full contextual completeness.

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?

With 100% schema description coverage, the input schema already documents all parameters. The description offers a tip about using referenceImages from gallery URLs but does not add significant semantic meaning beyond what the schema provides. Baseline score of 3 is appropriate.

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's purpose (generate an image using AI) and lists the supported platforms (MeiGen, ComfyUI, OpenAI-compatible APIs), making it easy to understand what the tool does and distinguishing it from sibling tools like get_inspiration and enhance_prompt.

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 a helpful tip on using get_inspiration() or enhance_prompt() to obtain prompts and suggests using gallery image URLs as referenceImages, guiding the agent on when to leverage sibling tools. However, it does not explicitly state when not to use this tool or provide alternatives for specific scenarios.

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