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

With no annotations provided, the description alone must disclose behavioral traits. It only states the action and does not mention side effects (e.g., session token invalidation), authentication requirements, idempotency, or error behavior. This is a thin description for a mutation-like operation.

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 concise in length but redundant: 'Logs out current logged in user session' and 'Log user out of the system' convey the same meaning. The wasted second clause reduces overall effectiveness.

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 no annotations and no output schema, the description should cover preconditions, side effects, and when to use. It only provides a one-line action with no additional context, leaving significant gaps for a tool that clears user state.

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% for the single parameter 'x-hapi-auth-state', and the tool description makes no mention of it. The agent receives no explanation of its meaning or necessity, so the parameter semantics are entirely absent.

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 current logged in user session'), using a specific verb ('logs out') and resource ('user session'). It differentiates from siblings like loginUser by the action itself, though it does not explicitly mention alternatives. Not a pure tautology because it adds context about 'current logged in user session'.

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?

No explicit guidance on when to use this tool versus alternatives. It does imply it should be used when a user is logged in, but there are no prerequisites, exclusions, or references to sibling tools like loginUser. The agent is left to infer basic usage.

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