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

With no annotations provided, the description carries full burden but provides minimal behavioral context. It states this creates a new customer/licensee (implying a write/mutation operation) but doesn't disclose permission requirements, rate limits, idempotency, error conditions, or what happens on success (e.g., returns created licensee object). The parameter descriptions add some operational context but not comprehensive behavioral traits.

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?

Well-structured with purpose statement followed by parameter explanations. The first sentence clearly states the tool's purpose. The Args section is organized but could be more concise - some explanations are slightly verbose (e.g., 'Optional custom licensee number (auto-generated if empty)' could be tighter).

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 this is a creation tool with no annotations, 6 parameters, and an output schema exists, the description is moderately complete. It explains all parameters well but lacks behavioral context about permissions, side effects, and error handling. The existence of an output schema means it doesn't need to describe return values, but other gaps remain for a mutation operation.

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, the description compensates well by explaining all 6 parameters in the Args section. It clarifies optional vs required status ('Optional', 'auto-generated if empty'), provides context for 'licensee_secret' (when product licenseeSecretMode is PREDEFINED), and explains boolean parameters' purposes. This adds substantial meaning beyond the bare schema.

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 'Create a new customer (licensee) under a product' - a specific verb ('Create') and resource ('customer/licensee') with context ('under a product'). It distinguishes from siblings like 'netlicensing_update_licensee' (update vs create) and 'netlicensing_get_licensee' (read vs create), but doesn't explicitly differentiate from other creation tools like 'netlicensing_create_product'.

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 on when to use this tool versus alternatives. The description doesn't mention prerequisites (e.g., product must exist), when not to use it, or how it relates to sibling tools like 'netlicensing_update_licensee' for modifying existing licensees or 'netlicensing_list_licensees' for viewing them.

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