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

No annotations are provided, so the description carries full burden. It states this 'retrieves' reference inputs, implying a read-only operation, but doesn't disclose behavioral traits like whether it requires authentication, has rate limits, returns structured data, or handles errors. The description is minimal and lacks essential operational context for a tool with no annotation coverage.

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 front-loads the core purpose. It avoids redundancy and wastes no words, though it could be more informative without sacrificing brevity. The structure is straightforward but lacks depth.

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 has an output schema (which handles return values), low parameter complexity (1 parameter), and no annotations, the description is minimally complete. It states the purpose but lacks usage guidelines, parameter details, and behavioral context, making it adequate only in a basic sense with clear gaps for effective agent use.

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%, so the description must compensate. It mentions 'a specific method' but doesn't explain what 'method_name' represents, valid formats, examples, or constraints. The description adds minimal meaning beyond the bare schema, failing to clarify parameter semantics adequately for the single required parameter.

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 'retrieves' and the resource 'reference inputs for a specific method', specifying it includes 'data and equations'. It distinguishes this as a lookup function rather than a calculation tool like its siblings. However, it doesn't explicitly differentiate from potential similar retrieval tools (none present in siblings).

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 guidance is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites, context for method selection, or relationships to sibling calculation tools (e.g., whether this should be called before or after them). It merely states what it does without usage context.

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