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

With no annotations, the description carries the full burden of behavioral disclosure. It clearly states two behavioral effects: ending the session and clearing the cached token. It does not, however, disclose consequences for subsequent calls or whether the operation is reversible, which is a minor gap.

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 with no filler and no redundant restatement of the tool name. It front-loads the primary action and then adds the token-clearing detail.

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 zero-parameter side-effect action with no output schema, the description is complete enough for an agent to know what will happen and when to invoke it. No additional context about return values or prerequisites is necessary at this complexity 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?

The tool has zero parameters and the schema coverage is 100%, so the description has no parameters to document. The baseline score of 4 applies because there is no parameter complexity needing explanation.

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 states a specific action ('End the session') and a specific resource ('FiberOne API'), and further clarifies a side effect: clearing the cached token. This distinguishes it from sibling login and other read-oriented 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?

Usage is clearly implied: to terminate the current session. However, the description does not explicitly state when to use it over alternatives, mention that authenticated calls will fail afterward, or reference the need to log in again. For a simple logout tool this is adequate but not explicit.

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