petstore-api.logoutUser

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

The description does not add behavioral context beyond what annotations already provide. Annotations indicate readOnlyHint=true and destructiveHint=false, yet the description does not clarify session invalidation, side effects, or authentication requirements. For a session-affecting operation, this is a missed opportunity to disclose behavior.

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, direct sentence with no unnecessary words. It earns its place and is immediately scannable.

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 the tool's simplicity (no parameters, clear action), the description is adequate. It doesn't mention return values, but an output schema exists, and the behavioral expectations for a logout operation are intuitively captured. Slightly more context (e.g., idempotent nature) could be added, but it's complete for practical purposes.

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 schema is empty. Per rubric, 0 params baselines at 4. The description doesn't need to elaborate on parameters, and the schema provides complete coverage (vacuously).

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 action ('Logs out') and the resource ('current logged in user session'). It is specific and distinct from sibling tools like loginUser. This is a textbook clear purpose statement.

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 provides no guidance on when to use this tool, any prerequisites (e.g., must be authenticated first), or alternatives. It simply states the function without context or exclusion criteria, offering no help for an agent deciding between tools.

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