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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool verifies installation and capabilities, but doesn't explain what happens during verification (e.g., whether it runs tests, checks system paths, or returns error codes), what permissions are needed, or if it has side effects like modifying files. This leaves significant gaps in understanding the tool's behavior.

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, efficient sentence that directly states the tool's purpose without unnecessary words. It's appropriately sized and front-loaded, making it easy to grasp quickly. Every word earns its place, contributing to clarity without redundancy.

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 moderate complexity (3 parameters, no annotations, but with an output schema), the description is incomplete. It covers the basic purpose but lacks details on behavior, parameters, and usage context. The presence of an output schema means return values might be documented elsewhere, but the description doesn't leverage this to explain what verification entails, leaving gaps in overall understanding.

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 3 parameters with 0% description coverage, and the tool description provides no information about them. Parameters like 'check_dot', 'check_latex', and 'detailed' are undocumented in both the schema and description, leaving their purposes unclear. The description fails to compensate for the low schema coverage, resulting in poor parameter understanding.

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 'Verify Doxygen installation and capabilities' states a clear verb ('verify') and resource ('Doxygen installation and capabilities'), but it's somewhat vague about what 'capabilities' entails. It doesn't differentiate from siblings like 'validate_documentation' or 'scan_project', which might also involve verification aspects. The purpose is understandable but lacks specificity.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, such as needing Doxygen installed first, or compare it to siblings like 'validate_documentation' for checking documentation quality. Without explicit or implied context, users must infer usage from the tool name alone.

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