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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds a small amount of useful context with 'Returns only data visible to the linked Market Brew account,' but says nothing about return format or the notion of a license definition. With annotations carrying the safety burden, a 3 is appropriate.

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 definition is short and front-loaded, which is good, but the first sentence is pure filler that echoes the tool name. It is appropriately sized yet does not earn its place.

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 read-only tool whose annotations cover safety, the remaining gap is the fully undocumented required parameter and the undefined concept of a 'license definition.' Without an output schema, the description should explain more about what is returned and what identifier shape the parameter expects, and it does not.

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 single required parameter 'licenseDefinitionSummary' is documented nowhere. The description gives no meaning, format, or example for this parameter, leaving the agent to guess what value to supply.

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 restates the tool name almost verbatim ('Use this when the user asks to get a license definition'), which is a tautology rather than a specific statement of what the tool does. It does not distinguish this tool from close siblings such as list_license_definitions, get_license_definition_form_fields, or get_customer_license.

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 only guidance is a circular 'when the user asks to get a license definition,' which provides no real disambiguation from the many other license-related siblings. There is no statement of when to prefer this over list_license_definitions or get_customer_license.

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