clear_element

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

Annotations only declare destructiveHint: false. The description does not disclose any behavioral traits beyond what the annotation implies. It fails to mention whether clearing triggers events, works on disabled elements, or what happens to non-input elements—important details for an agent to anticipate side effects.

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 concise sentence with no wasted words. It is front-loaded with the core action. However, it omits useful details that could be added in one more sentence, so it is not maximally informative.

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 simple one-parameter tool with no output schema, the description is minimally adequate. It fails to explain what the tool returns (void), what types of elements are supported (only input elements?), or how it interacts with other tools. The sibling set shows many related actions, so more context would help the agent choose correctly.

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?

The input schema provides full coverage with a clear description for elementId ('Element ID returned by find_element'). The tool description adds no extra semantic meaning about the parameter, so it meets but does not exceed the baseline for full schema coverage.

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?

Description clearly states the action ('Clear') and the target ('text content of an input element'). This distinguishes it from sibling tools like set_value (which sets new text) or get_text (which reads text). The verb+resource pairing is specific and unambiguous.

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?

No guidance is provided on when to use clear_element instead of alternatives like set_value, send_keys, or set_element_value. There is no mention of prerequisites (e.g., element must be interactable) or context in which clearing is appropriate.

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