ibmcloud_logout

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Logout' only states the action; it does not disclose what happens during logout (e.g., whether local credentials are removed, session tokens revoked, or if re-login is required). This lack of detail is a significant gap for a tool that affects authentication state.

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, concise sentence 'Logout from IBM Cloud' that is front-loaded and contains zero unnecessary words. It perfectly meets the requirement for appropriate sizing and structure.

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 simplicity of the tool (no parameters, no output schema, a single clear action), the description is almost complete. However, it could benefit from a note about the effect on the session or credentials, as might be expected in a logout operation. This minor gap keeps it from a 5.

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 baseline is 4. The description adds no parameter information, but none is needed since the schema is empty. The description is adequate for a no-argument tool.

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 'Logout from IBM Cloud' clearly states the action and resource, with a specific verb 'Logout'. It is easily distinguishable from the sibling 'ibmcloud_login' and other tools, leaving no ambiguity about its function.

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 does not explicitly state when to use this tool or provide exclusions. However, given the sibling tool 'ibmcloud_login', the usage is implied as the counterpart to log out after a session. No explicit alternatives or conditions are provided, but the context makes it understandable.

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