Understand Technical Diagram

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

No annotations are present, so the description must fully disclose behavioral traits. It only says 'explain' without detailing how the explanation is delivered (e.g., text, structured data), what input is required beyond 'image_source' and 'prompt', or any limitations (e.g., supported image formats, resolution).

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 a single sentence that directly states the tool's purpose and lists supported diagram types. It is front-loaded and avoids redundancy, though it could be more structured by including input/output hints.

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 three parameters (two required) and no output schema or annotations, the description should explain the expected return format, prerequisites (e.g., valid image URL), or examples. It fails to do so, leaving the agent uncertain about how to invoke the tool correctly.

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%, meaning the description must compensate. It only loosely implies that 'diagram_type' corresponds to listed types, but does not explain the meaning or constraints of 'image_source' or 'prompt' (e.g., what constitutes a valid prompt). No additional parameter-level context is provided.

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 verb ('Explain') and the resource ('technical diagrams'), and enumerates specific diagram types (architecture, flowcharts, UML, ER). However, it does not explicitly differentiate from sibling tools like 'analyze_data_visualization' or 'analyze_image', which could also handle technical diagrams.

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 usage guidance is provided. The description does not specify when to use this tool versus alternatives, nor does it mention prerequisites or cases where the tool should not be used.

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