type_and_submit

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

The description adds minimal behavioral insight beyond the schema. It repeats that a key is pressed (default Enter) and that text is typed. It does not disclose whether the field is cleared first, whether it waits for navigation, or any side effects. With no annotations, more detail would be needed.

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 only two sentences, concise and front-loaded. Every sentence is necessary and adds value.

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 tool has 5 parameters and no output schema. The description does not explain return behavior, whether the tool waits after pressing the key, or any error conditions. For a submission action, this leaves significant gaps.

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 100%, so baseline is 3. The description does not add extra meaning beyond the schema's parameter descriptions. It mentions text and key but provides no new semantic detail.

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 clearly states the tool types text and presses a key (default Enter). It specifies the use case: search boxes and single-field forms, distinguishing it from siblings like 'type_text' (which only types) and 'fill_form' (which fills multiple fields).

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 provides context by stating it is useful for search boxes and single-field forms, implying when to use it. It does not explicitly name alternatives or state when not to use it, but the context is clear enough.

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