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

With no annotations, the description carries full burden but provides minimal behavioral insight. It states 'Get' implying a read operation, but doesn't disclose authentication needs, rate limits, error handling, or response format. The description adds no context beyond the basic action, leaving key traits like safety and performance undocumented.

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 brief and front-loaded with the main purpose, followed by a parameter note. It avoids redundancy and uses clear language. However, the two-sentence structure could be more integrated, and the 'Args:' section might be slightly verbose for a single parameter, but overall it's efficient.

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 low complexity (single parameter, read operation) and the presence of an output schema (which handles return values), the description is reasonably complete. It covers the basic action and parameter, though it lacks behavioral details. With annotations absent, it could benefit from more context, but the output schema reduces the burden.

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%, but the description adds minimal semantics: it identifies 'module_number' as a 'Module identifier'. This clarifies the parameter's role beyond the schema's generic 'string' type. However, with only one parameter and no details on format or constraints, it partially compensates but remains basic, aligning with the baseline for moderate 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 verb 'Get' and resource 'a specific product module', making the purpose evident. It distinguishes from siblings like 'netlicensing_list_product_modules' by specifying retrieval of a single module rather than listing. However, it doesn't explicitly contrast with other 'get' tools (e.g., 'netlicensing_get_product'), leaving some ambiguity.

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. It doesn't mention prerequisites (e.g., needing an existing module), compare to 'netlicensing_list_product_modules' for browsing, or specify use cases like retrieving details for updates. The description lacks context for selection among sibling tools.

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