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

With no annotations, the description carries the full burden and adds meaningful behavioral context: 'Safe to call at any time' implies idempotency and that the tool won't error or cause side effects even if no browser is open. It also clarifies the tool's scope as closing only the browser opened by the sibling tools.

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?

A single sentence that front-loads the core action ('Close the browser') and appends the key safety note. Every word earns its place; there is no redundancy or filler.

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 cleanup tool with an output schema present, the description fully covers what the tool does and when it is safe to call. No additional details about return values are necessary because the output schema exists.

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 input schema has zero parameters, so the baseline is 4 per the rubric. The description adds no parameter info, but none is needed since the tool requires no arguments.

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 uses a specific verb ('Close') and a clear resource ('the browser opened by these tools'), making the action unambiguous. It also distinguishes this from sibling forecast tools by identifying it as a cleanup operation on a browser instance rather than a forecast-related action.

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 phrase 'Safe to call at any time' provides explicit state-independent guidance, telling the agent it can invoke this tool without prerequisites or timing concerns. It does not name alternatives, but none exist for closing the browser, so the guidance is sufficient.

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