nested_click

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

With no annotations, the description carries the burden of behavioral disclosure. It transparently notes that an exception is raised if the element is not found within the default timeout, which is useful. It does not cover visibility, scrolling, or wait behavior, but the core failure behavior is stated.

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 two succinct sentences, front-loaded with the operation and an illustrative example. Every sentence adds value: the first defines the action, and the second communicates an important failure behavior.

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 is adequate for a basic two-parameter click operation, and an output schema exists so return-value explanation is not required. Gaps include lack of detail about accepted selector syntax, whether the parent is an iframe locator or a regular element, and behavior when the parent itself 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 compensate. 'Nested inside another' and the iframe example help map parent_selector to the containing element and selector to the target element, but exact selector syntax and the precise parent-child relationship are not fully detailed.

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 names a specific verb ('Click') and resource ('an element nested inside another'), with an iframe example that clarifies the intended use. It is reasonably distinct from sibling tools like click_link or click_nth_element, though it does not explicitly name or contrast them.

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 a clear condition for use: when the target element is nested inside a parent element or iframe. However, it does not explicitly say when not to use this tool or mention alternative click-related sibling tools.

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