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

With no annotations provided, the description carries the full burden of behavioral disclosure. It describes what the tool returns ('per-module validity, type, expiry dates, and usage counts') which is helpful, but doesn't mention important behavioral aspects like whether this is a read-only operation, if it has side effects, authentication requirements, rate limits, or error conditions. The parameter hints about 'auto-created licensees' and model types add some context but leave significant gaps.

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 well-structured with a clear purpose statement followed by return value information and parameter explanations. Each sentence adds value, though the parameter section could be more efficiently formatted. The front-loaded purpose statement is effective, and there's minimal redundancy or wasted verbiage.

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 complexity (7 parameters, validation logic, multiple licensing models) and the presence of an output schema, the description is moderately complete. It explains the purpose and parameters reasonably well, and the output schema will handle return values. However, for a validation tool with no annotations and complex parameter interactions across different licensing models, more behavioral context would be beneficial to understand side effects, error conditions, and proper usage patterns.

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?

With 0% schema description coverage for 7 parameters, the description provides valuable semantic context beyond the bare schema. It explains that 'product_number' is optional and scopes validation, 'licensee_name' is for auto-created licensees, 'session_id' is for floating models, 'action' can be 'checkOut' or 'checkIn', and two parameters are for NodeLocked models. This significantly enhances understanding of when and how to use each parameter, though some details remain unspecified.

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: 'Validate a customer's licenses across all product modules.' It specifies the verb (validate) and resource (customer's licenses), and distinguishes it from siblings like 'get_licensee' or 'list_licenses' by focusing on validation rather than retrieval. However, it doesn't explicitly contrast with all possible alternatives among the many sibling tools.

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. With 44 sibling tools including various get, list, create, update, and delete operations, there's no indication of when validation is appropriate versus checking license status via other means. The parameter descriptions imply some usage contexts (e.g., 'when licenseeAutoCreate is enabled'), but no explicit when/when-not guidance is provided.

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