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

With no annotations, the description carries the behavioral disclosure burden. It transparently mentions the optional press_enter and clear_first behaviors, but it does not state whether the tool waits for the element, focuses the field, fires real key events, or what happens when the selector is not found. Core behavior is clear, but edge behavior is not disclosed.

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 purpose statement is front-loaded, and the Args block directly lists all four parameters with no filler or repeated information. Every sentence adds value, and the structure is easy to scan.

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 names the target context ('current Comet page'), explains all parameters, and the presence of an output schema means return values do not need to be detailed. It is complete enough for a simple typing tool, though explicit guidance about when to choose it over siblings 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?

Schema description coverage is 0%, so the description must explain all parameters. It provides a concise semantic line for each of the four parameters, including the meaning of the boolean flags. This compensates well for the empty schema, though it does not go deeper into selector syntax or input validation.

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 action ('Type text into an input field') and scopes it to 'the current Comet page,' making the tool's purpose immediately clear. This also distinguishes it from sibling tools like comet_click and comet_evaluate without needing to inspect their schemas.

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 no explicit guidance on when to use this tool versus alternatives such as comet_click or comet_evaluate. It provides context about the current page but no exclusions, conditions, or routing hints, so an agent is left to infer when this is the appropriate choice.

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