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

With no annotations provided, the description carries the full behavioral burden and does disclose useful traits: inter-key delays, rare typos, and pauses. However, it omits important behavior such as whether the selector is focused first, whether existing text is replaced or appended, whether injected typos are corrected, and what side effects occur on the page.

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 wasted words. The parenthetical details add useful behavioral context efficiently.

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 two required parameters, no annotations, no output schema, and 0% schema description coverage, the description is too sparse. It explains the human-like typing style but leaves the selector semantics, text behavior, and element interaction details undocumented.

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 0%, so the description must compensate but does not mention either required parameter. It vaguely implies a text input through the verb 'Type', but gives no meaning for 'selector' or whether text replaces or appends to existing content.

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, 'Type', and adds behavioral qualifiers: human-like inter-key delays, rare typos, and pauses. This distinguishes it from sibling actions like click, scroll, or open, though it does not clarify the target element context beyond the schema's selector parameter.

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 human-like typing phrase implies when this tool might be preferred, but there is no explicit guidance on when to use it versus alternatives or when not to use it. No prerequisites or alternative tools are mentioned.

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