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

The description reveals key behavioral traits: time-limited, single-use, and embedded authentication. Annotations are minimal (no readOnly or destructive hints), so the description compensates well by explaining these side effects and constraints.

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, concise sentence that conveys the core functionality without unnecessary fluff. It is appropriately sized for the tool's simplicity.

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?

While the tool's basic action is described, the description omits details about the parameters and the returned token's usage or format. Given the existence of an enum for token_type, more context would be helpful. It is adequate but not fully 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?

The input schema defines two parameters (account and token_type) with no descriptions, and the description does not explain either parameter. This provides zero added meaning beyond the schema, failing to compensate for the lack of schema-level documentation.

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 purpose: generating a time-limited, single-use token with embedded authentication for frontend clients. It is specific and distinct from other sibling tools.

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 mentions it is for frontend clients, which gives some context, but it does not explicitly compare with alternatives or state when to prefer this over other tools. It lacks explicit usage guidance.

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