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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description correctly does not repeat that. It adds valuable context by indicating that the tool returns the official license_id and certificate PDF URL upon completion, which implies a stateful process. This is useful beyond the annotations and does not contradict them.

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, front-loaded sentence that states the core purpose and key outputs. There is no redundant information, and every word contributes to understanding the tool. This is an exemplary concise structure.

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 simple tool with one input and no output schema, the description covers the return values but omits essential context: what the license_token is for, and when to use this tool (e.g., after creation or payment). The description gives adequate information about what happens 'when completed' but lacks details on the interim state or error handling. Overall, it meets the minimum viability but leaves gaps in usage and parameter semantics.

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 single parameter license_token is not mentioned in the description, and schema description coverage is 0%. The description provides no guidance on where the token comes from or its format. Although the parameter name is somewhat self-explanatory, the tool definition fails to compensate for the complete lack of schema-level semantics.

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 indicates the tool retrieves license status and specifies the key outputs (license_id and certificate PDF URL). It distinguishes from siblings like create_commercial_license and pay_commercial_license by focusing on retrieval of status. However, it does not explicitly name the action verb (e.g., 'get' or 'retrieve'), relying on the tool name.

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 does not mention that it should be used after create_commercial_license or pay_commercial_license, nor does it state any exclusions or prerequisites. The context from sibling names implies a workflow but the description itself offers no such direction.

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