execute_atomic_action

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

No annotations are provided, so the description carries the full burden of disclosing side effects. It only says 'execute' with no mention of browser state changes, navigation, permissions, return values, or error behavior. For a tool that performs actions on a live page, this is a significant transparency gap.

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?

One short sentence directly states the core function with no filler or repetition. It is front-loaded and appropriately sized for a tool that relies on the schema for parameter details.

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?

This is a core execution tool with no output schema and no annotations, yet the description does not explain supported action types, how text_input is used, what a successful execution looks like, or potential side effects. Given the tool's moderate-to-high complexity, this is under-specified and depends heavily on external knowledge of get_element_details.

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 schema covers both parameters with descriptions (100% coverage), so the baseline applies. The description adds a minor contextual cue that the action object comes from get_element_details, but it does not explain parameter interrelationships or constraints beyond the schema.

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 uses the specific verb 'execute' with the resource 'atomic action' and states it originates from get_element_details, which clearly distinguishes it as the counterpart to that tool. However, it does not define what an atomic action is, leaving some ambiguity for agents unfamiliar with the workflow.

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 explicitly says the action must be 'generated by get_element_details', establishing a clear before/after relationship and indicating when to use it. It does not mention alternatives or when not to use this tool, but the source constraint gives solid context.

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