Logout from Bridge

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

Annotations already indicate readOnlyHint=false and destructiveHint=true, so the description's statement that the tool logs out is consistent but adds no additional behavioral context, such as side effects on other sessions or subsequent tool availability.

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 one sentence of 9 words, perfectly concise and front-loaded. Every word is meaningful and there is no waste.

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, no output schema, and the destructive annotation, the description is minimally sufficient. However, it lacks details on expected behavior post-logout, such as whether the user must re-authenticate, and does not describe the response. A more complete description would note these aspects.

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 has no parameters, so description coverage is 100%. The description does not need to explain parameters. Baseline score of 4 is appropriate as no further parameter clarification is required.

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 the current session from Proton Mail Bridge', specifying the verb 'Logs out' and the resource 'session from Proton Mail Bridge'. It effectively distinguishes from siblings like proton_bridge_login.

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 versus alternatives. It does not mention prerequisites, such as an active session, nor does it contrast with proton_bridge_login or other related tools. The agent must infer usage context.

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