Logout Session

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

With no annotations provided, the description must disclose behavioral traits. It states that the tool removes a session from server memory, indicating a destructive action. However, it does not explain error handling (e.g., if session doesn't exist), side effects (e.g., invalidating tokens), or authentication requirements for using this tool. Basic transparency but insufficient depth.

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 sentence that is both concise and front-loaded with the core action. Every word earns its place; there is no extraneous information. This is exemplary conciseness for a simple tool.

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 tool with one required parameter and no output schema, the description provides the essential action but omits critical context: success/error behavior, prerequisites (e.g., session must be active), and post-conditions. The gaps lower its completeness to an adequate but not thorough level.

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 description must compensate by explaining parameter meaning. It does not mention the 'session_id' parameter at all. While the parameter name is somewhat self-explanatory, the description adds no value beyond the schema definition, leaving agents without context on what value to provide.

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 ('removes'), the resource ('one stored authenticated session'), and the scope ('from server memory'). It distinguishes from sibling tools like bootstrap_session or login tools, which create or manage sessions, not destroy them.

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 implies usage (to end/remove a session), but provides no explicit guidance on when to use this tool versus alternatives, prerequisites (e.g., must have an active session), or contraindications. The context makes it moderately clear, but lacks direct instruction.

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