browser_handle_dialog

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

With no annotations, the description carries the full behavioral burden. It names dialog types but omits the key semantics: whether accept=false dismisses the dialog, that promptText only applies to prompt dialogs, what happens if no dialog is pending, or whether the action is reversible.

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 front-loaded sentence with zero filler; the parenthetical enumeration is efficient. It is terse to the point of under-specification, but nothing is wasted.

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 disabled-annotation, 0%-coverage, 2-parameter mutation tool with no output schema, the description is too thin. Neither parameter semantics nor the dialog lifecycle is covered, so an agent lacks what it needs to call it correctly in context.

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?

Schema coverage is 0% and both parameters are bare (accept: boolean, promptText: string). The description clarifies nothing about the accept/promptText pairing or the dismiss-vs-confirm meaning, leaving the agent to guess how to fill them.

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 ('Respond') and resource ('the next dialog'), and enumerates the dialog types (alert/confirm/prompt/beforeunload), so the agent immediately knows the operation. It does not explicitly contrast itself with siblings, but no other tool in the list concerns dialogs, so the distinction is effectively unambiguous.

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?

There is no guidance on when this must be called: it does not say a dialog blocks page interaction, that it should be invoked after a dialog is triggered, or how it relates to other browser tools in the flow. 'Next dialog' hints at queuing order but no when/when-not condition or alternative is given.

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