log_out

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

The description adds the workflow context of switching to a local server, which is useful beyond the annotations. However, it does not disclose details about session invalidation or post-logout behavior. The annotations (idempotentHint: true, destructiveHint: false) already provide a safety profile, so the description adds modest value.

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 two short sentences, front-loaded with the core purpose and followed by a specific usage tip. Every word earns its place, and there is no redundancy or vague filler.

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 (zero parameters, no output schema) and the annotations covering safety traits, the description is complete. It states what the tool does and when to use it, which is sufficient for a logging-out utility.

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 the schema coverage is 100% (vacuously). The description does not need to explain parameters, and none are present. The baseline of 4 for a zero-parameter tool applies, as there is nothing to compensate for.

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 ('Log out') and the specific target ('cloud Bot API server'), making the tool's purpose unambiguous. It distinguishes itself from siblings by focusing on session termination on the cloud server, which is not covered by other 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 provides an explicit usage scenario: 'Use before moving to a local server.' This gives clear context for when to invoke the tool, though it does not explicitly mention alternatives or when not to use it. The guidance is sufficient for a zero-parameter utility.

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