click

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 behavioral traits. It only states the action without revealing crucial behavior such as whether it waits for the element to be visible/clickable, how it handles multiple matches, or what happens on failure (timeout exceptions). This is insufficient for an agent to predict side effects 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?

The description is a single sentence that is direct and free of redundancy. It is appropriately sized and front-loaded with the essential purpose. Every word contributes to the meaning.

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?

While the tool is simple, the description lacks important context such as whether it performs a single or multiple clicks (if multiple elements match), any preconditions (e.g., element must exist), and the meaning of the timeout parameter. With no annotations or output schema, the description is too sparse to fully guide an agent in varied usage scenarios.

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. It explains the 'selector' parameter (CSS selector) but completely omits the 'timeout' parameter, its meaning, or its default behavior. Only half of the parameters are semantically enriched.

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 action: 'Click an element identified by CSS selector.' It specifies the verb (click), the resource (element), and the identification method (CSS selector). It distinguishes from the sibling tool 'click_text' by indicating this tool uses CSS selector rather than text.

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 no guidance on when to use this tool versus alternatives like 'click_text' or other navigation tools. It does not mention context (e.g., dynamic pages, multiple matches, or waiting conditions) or explicitly state exclusions or preferred scenarios.

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