browser_overlay_dismiss

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It mentions automatic identification and clicking but lacks details on potential side effects (e.g., accidental clicks on interactive elements), what happens if no overlay is found, or safety guarantees. This is a significant gap for a tool that performs automated clicking.

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 that front-loads the purpose and includes relevant examples. It is efficient with no wasted words, though it could benefit from clearer structuring (e.g., separating behavior from parameter details).

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?

The description covers the tool's core function and parameter but does not mention return values, success/failure behavior, or error handling. Since no output schema exists, the description should provide more context on what the tool returns, which is missing.

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 schema coverage is 100%, with the parameter 'format' fully described by its enum values in the schema. The description does not add any extra meaning beyond the schema, so the baseline score of 3 is appropriate.

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 clearly states the verb '自动关闭' (automatically dismiss) and the resource '遮挡物' (overlays), with specific examples (Cookie banners, popups, floating layers, masks). It distinguishes this tool from siblings like 'browser_overlay_detect' by including the action of closing, not just detecting.

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 description implies usage for dismissing common overlays automatically, but provides no explicit guidance on when to use this tool versus alternatives (e.g., 'browser_overlay_detect', 'browser_click'). No exclusions or prerequisites are mentioned.

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