handle_dialog

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

With no annotations, the description carries the behavioral burden. It discloses an important implementation trait: it uses CDP Page.javascriptDialogOpening, so it functions even while the dialog blocks all JavaScript. It also warns that configuration must happen before the triggering action. Minor gaps remain, such as whether the handler persists across dialogs, but the provided behavioral detail is meaningful.

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 compact sentences with no filler. The purpose is front-loaded, and the critical timing caveat and CDP mechanism each earn their place.

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 two-parameter tool with full schema coverage, the description is largely complete: it explains purpose, timing, and mechanism. The only missing piece is the exact shape of get_status output, but the action is simple enough that the schema enum plus 'pending ones' provides adequate guidance.

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 description coverage is 100%, so the input schema already fully documents both parameters and the enum values. The description adds no additional parameter meaning, which is acceptable given the baseline for fully covered schemas.

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 states a specific verb ('Configure') and a precise resource ('handling of alerts, confirms and prompts'), clearly distinguishing this from the browser-interaction siblings like click, type, and navigate. No other sibling targets JavaScript dialogs.

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 gives clear usage context: set this before triggering the action that opens the dialog, and it works even when the dialog blocks JS. It does not explicitly enumerate alternatives or exclusions, but no sibling tool handles dialogs, so the routing is still clear.

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