list_logout

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

Annotations already declare readOnly, idempotent, and non-destructive behavior, and the description adds the HTTP route. However, it does not explain what happens when the endpoint is called, whether a session is invalidated, or what authentication state is expected. The annotation coverage lowers the burden, but the description adds little behavioral context beyond the path.

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 extremely short and front-loaded with the endpoint, containing no wasted content. However, 'Read Authentication' reads like boilerplate rather than a genuinely informative summary of the logout behavior.

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?

Given zero parameters, an output schema, and safety-related annotations, the description does not need to explain return values or side-effect safety. Still, it is incomplete operationally: it does not clarify the difference between a logout endpoint and a login/read-authentication endpoint, which is the main thing an agent needs to know.

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 and zero required parameters, so the input schema is complete and the description has no parameter burden to carry. The baseline of 4 applies because there is nothing for the description to clarify.

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 provides a concrete endpoint ('GET /logout') and labels the resource ('Authentication'), but it never explicitly states that this logs the user out. The phrase 'Read Authentication' is vague and could also describe list_login or a status endpoint, so the agent must infer intent 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?

There is no guidance about when to use this tool versus alternatives such as list_login or create_login. No context, preconditions, or exclusions are given, so an agent has no help choosing between authentication-related endpoints.

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