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

The annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false. The description adds useful behavioral scope by clarifying that only 'this connection' is signed out and the receiving Desktop is not affected. It does not cover permissions or post-sign-out effects, so it is not fully comprehensive.

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 compact sentences with no wasted text. The primary purpose and the important non-effect on the receiving Desktop are front-loaded and easy to scan.

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 sign-out action with no output schema, the description is largely complete: it states the account-panel context and the connection-level scope. It could still say more about what happens after sign-out or whether any status is returned, but the essential information for correct invocation is present.

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 takes zero parameters, so the baseline score is 4 per the rubric. There are no parameter semantics to explain, and the schema is empty.

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 names a specific verb and resource: 'sign out this connection' for the account panel. It also scopes the action by saying it does not sign out the receiving Desktop, though it does not explicitly distinguish itself from the counterpart view_sign_in sibling.

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?

It gives a clear usage context: use it for the account panel after the user presses Sign out. It also states an exclusion, 'Does not sign out the receiving Desktop,' but does not name alternative tools such as view_sign_in or other connection-management siblings.

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