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, and it discloses little beyond the action itself. It does not say whether the click waits for navigation or network idle, how it behaves on hidden/disabled/covered elements, whether it auto-scrolls, or what errors to expect.

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?

A single front-loaded sentence with no wasted words; the action and its identifier mechanism are stated immediately.

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 one-parameter tool with no output schema, the description is minimally adequate. However, with no annotations covering safety or side effects and no mention of navigation waiting or failure modes, an agent lacks the behavioral context needed to invoke it confidently.

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?

With a single parameter at 100% schema description coverage, the schema already documents the selector format. The description restates that the selector may be a CSS selector or an @eN handle, which is redundant with the schema and adds no format or precedence details.

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 states a specific verb (Click) and resource (an element on the page) and names the two accepted identifier forms (CSS selector or @eN snapshot handle). It is clear on its own, though it does not explicitly differentiate itself from siblings like browser_fill or browser_type that also act on elements.

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?

There is no statement of when to use this tool versus alternatives such as browser_fill, browser_type, or browser_send_keys, all of which also target elements. Usage is only implied by the tool name and the mention of the @eN handle sourcing from browser_snapshot.

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