Assign License To User

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

Annotations already indicate a non-read-only, non-destructive write operation. The description adds valuable behavioral context: it sets usageLocation before assigning the license and fails if the usageLocation is missing. This discloses a side effect and failure condition beyond what annotations provide, without contradiction.

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 sentence that front-loads the core action, then adds a concise behavioral note. Every word earns its place, with no filler or repetition.

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?

For a 4-parameter tool with no output schema, the description is adequate but leaves gaps. It covers the key behavior and failure mode but does not explain disabledPlans, the expected format for user/license, or return values. It is a viable minimum but not richly complete.

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 should compensate. It only clarifies usageLocation ('Sets usageLocation first when provided'), while user and license are self-explanatory from the tool name. However, disabledPlans is left completely unexplained—an agent would not know what it means without additional context.

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 action: 'Assign a license to a user.' This is a specific verb+resource that distinguishes it from siblings like remove_license and set_usage_location. It also adds a unique behavioral note about usageLocation, further clarifying its purpose.

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 implies usage context by stating 'Sets usageLocation first when provided; fails clearly if the user has no usageLocation.' This suggests when to use the tool (to set usageLocation inline) and a prerequisite (user must have a usageLocation), but it does not explicitly name alternatives like set_usage_location or state when not to use it.

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