A4.3/5.0

Behavior3/5

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

The destructiveHint annotation already signals this is a destructive action, and the description confirms it by saying 'Close' and 'clean up resources'. It adds some scope detail ('current browser session') but does not describe side effects such as invalidating cookies, logging out the user, or making the session unusable. Since the annotations carry much of the safety signal, a mid-range score is appropriate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The entire description is a single, front-loaded sentence with no redundant words. It states the action and consequence efficiently, earning a top score for conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter, destructive tool with an output schema and annotation coverage, the description is complete enough for an agent to know what will happen. The absence of an alternative, zero parameters, and existing destructiveHint mean no additional operational context is essential.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters and the schema is empty with 100% coverage, so there are no parameter semantics for the description to clarify. With no params, the baseline is 4, and the description does not need to add parameter-level explanation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Close') and names the resource ('current browser session') plus a clear secondary purpose ('clean up resources'). It is well-distinguished from all sibling tools, which focus on profiles, searches, messaging, and feed actions, not session lifecycle.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear context that this tool ends the current browser session, implying it should be used when the session is no longer needed. There are no sibling tools providing an alternative session-close action, so explicit exclusions are unnecessary. A fully explicit 'use this when you are done' statement would improve clarity, but the context is already strong.

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