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 'Get details' which implies a read-only operation, but it doesn't clarify aspects like authentication requirements, rate limits, error handling, or what 'details' include (e.g., status, expiration). For a tool with no annotations, this leaves significant gaps in understanding its 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 appropriately sized with two sentences: a clear purpose statement and a parameter explanation. It's front-loaded with the main function, and the 'Args' section is structured but could be more integrated. There's minimal waste, though it could be slightly more polished.

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), a single parameter, and no annotations, the description is reasonably complete. It states the purpose and parameter, but could improve by adding usage guidelines or behavioral details to fully compensate for the lack of annotations, especially for a read operation in a context with many sibling tools.

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 description includes an 'Args' section that documents the single parameter 'license_number' as 'License identifier', adding meaning beyond the input schema which has 0% description coverage. However, it doesn't provide examples, format details, or constraints (e.g., length, allowed characters), so it partially compensates but not fully for the low schema coverage.

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 with a specific verb ('Get details') and resource ('specific license'), making it immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'netlicensing_get_licensee' or 'netlicensing_list_licenses', which would require mentioning it retrieves a single license by identifier rather than listing or fetching other entities.

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 sibling tools like 'netlicensing_list_licenses' for listing multiple licenses or 'netlicensing_get_licensee' for related entities, nor does it specify prerequisites such as needing an existing license number. Usage is implied but not explicitly stated.

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