browser_dismiss

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

No annotations exist, so the description carries the burden, and it does disclose real behavior: it performs visible clicks on multiple control types and repeats 'one after another' until done. What's missing is the outcome contract — what it returns, and what happens if no popup is found or a control can't be clicked.

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?

Two tight sentences: the action and its mechanics first, then the trigger condition. Nothing redundant or padded.

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 simple one-parameter tool with no output schema, the description covers what it does, how, and when to call it. Only the return/result signal and the no-op case are left unstated.

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?

Single parameter with 100% schema coverage; the schema already explains that 'tab' is the id returned by browser_open. The description adds no further guidance on the tab argument, so baseline 3 applies.

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?

States a specific verb (close) and resource (popups/overlays covering the page), plus the concrete mechanism (clicking 닫기/close/× and 'do not show today' controls). This implicitly separates it from tab-closing siblings like browser_close and browser_close_mine, though it never says so explicitly.

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?

Gives a precise triggering condition: 'Use it when a click reports "covered".' That is a clear reactive-use signal an agent can act on. It does not name alternatives (e.g., don't reach for browser_close) or say what to do if nothing gets dismissed.

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