Type Text

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

With no annotations provided, the description partially fulfills the burden by mentioning return of a fresh page snapshot and resulting changes (validation, autocomplete). However, it omits details like focusing the element, waiting for interactivity, or error conditions.

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?

Three concise sentences with front-loaded information. Every sentence provides value: core action, clear behavior, and return value. No wasted words.

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?

Given 4 parameters, no output schema, and 27 sibling tools, the description covers the main action and return but lacks comparison to siblings like 'press' and does not mention prerequisites (e.g., element must be input/textarea).

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 the description adds only minor context (e.g., 'replace existing content' for the 'clear' parameter). It does not significantly enhance understanding beyond what the schema already provides.

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's action ('Type text into an input field or text area') using a specific verb and resource ('by eid'). It distinguishes from sibling tools like 'click' and 'select' by focusing on text input.

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 basic context ('by eid', return snapshot) but does not explicitly state when to use this tool versus alternatives like 'press' or 'select'. No when-not-to-use guidance is given.

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