Browser Keyboard Type

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether text is typed into the currently focused element, whether it simulates keystrokes that trigger page events, or whether it requires prior navigation/focusing. Key behavioral traits that an agent needs to predict side effects are absent.

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, front-loaded sentence with no filler or redundant wording. It is efficient, although arguably too terse to carry the behavioral and usage context that the tool needs.

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 tool with three parameters, no annotations, no output schema, and many closely related siblings, the description is insufficiently complete. It lacks information about session requirements, focus/active-element behavior, and how it differs from form filling or key-press tools. An agent cannot confidently select and invoke it correctly based solely on this definition.

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 only 33%, and the description adds no meaning beyond the schema. The 'text' parameter is only implied by the verb 'type', 'sessionId' is not explained as identifying the active browser session, and 'delay' is already documented in the schema. The description does not compensate for the under-documented parameters.

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 and resource: 'Type text into the active page.' It clearly identifies the tool as a text-typing operation, though it does not explicitly differentiate itself from sibling tools like browser_keyboard_press or browser_fill. The core purpose is still understandable at a glance.

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 to use this tool versus alternatives such as browser_keyboard_press, browser_fill, or browser_fill_form. The description does not mention prerequisites like having an active session or focusing an element before typing. Usage context must be entirely inferred by the agent.

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