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

With no annotations provided, the description carries the full burden. The verb 'Get' implies a read-only operation and the phrase 'authenticated agent' signals an authentication requirement, but it does not disclose error conditions, side effects, or output behavior. A more explicit read-only/authentication statement would improve transparency.

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 conveys all essential information without superfluous words. Every word earns 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 simple, parameterless read-only tool, the description is largely complete. It does not explain the output structure, but no output schema exists, and 'profile' is reasonably self-explanatory given common usage. Minor gaps remain around expected response fields.

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 tool has zero parameters, so the input schema fully covers the parameter surface. The description adds no parameter-specific meaning, but none is needed; baseline for 0-parameter tools is 4.

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 uses a specific verb 'Get' and names the precise resource 'authenticated agent's profile', which distinguishes it from all sibling tools focused on loyalty, marketplace, or reports. Adding 'authenticated' clarifies the otherwise ambiguous 'my' from 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?

The description clearly implies the tool is for retrieving one's own profile, and no sibling tool serves a similar purpose. It does not explicitly state when not to use it, but the context is unambiguous due to the unique scope.

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