Analyze Image

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

No annotations are provided, so the description must disclose behavioral traits such as side effects, authentication needs, or output format. It fails to mention any, leaving the agent uninformed about what happens when the tool is invoked.

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 very short (12 words), but it sacrifices informativeness for brevity. It does not earn its place as it fails to provide necessary context for usage.

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 no annotations, no output schema, and two undocumented parameters, the description is severely incomplete. An agent cannot safely or effectively use this tool based on the provided information.

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?

The input schema has 0% description coverage, and the tool description does not explain the role of 'image_source' or 'prompt'. This leaves the agent without understanding how to construct a valid request.

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 indicates it is a general-purpose image analysis tool, contrasting with specialized siblings. However, it lacks specificity about what analysis entails (e.g., object detection, color analysis), making the purpose vague.

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 explicitly states to use this tool 'for cases not covered by the specialized image tools,' providing clear context for when it is appropriate. It does not elaborate on specific exclusion criteria or name alternatives, but the guidance is direct.

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