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

With no annotations, the description carries the full burden and does well: it discloses the human-like pointer pace, the hard safety stop on pay/buy/submit/delete-like controls returning 'ask the human', and that the result url reflects where the tab ended up. It stops short of covering failure modes or whether the call waits for navigation to settle.

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?

Three dense sentences, zero filler, with the locator strategy stated first and the safety behavior and return semantics following.

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?

No output schema exists, yet the description explains the meaningful return field (result url). Safety and targeting are covered; only error/edge behavior is left implicit, which is a minor gap for a click tool.

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 coverage is 67%, and the description mostly reinforces what the schema already says (css as fallback vs role+name). It adds no detail on tab, index, name, or pace beyond the field-level descriptions, so the undifferentiated 'role' and 'name' params remain unexplained in prose.

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?

Specific verb (click) plus target resource (a control) and the two ways to identify it (role+name preferred, css fallback). An agent can distinguish it from sibling browser_type without opening the schema.

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?

It gives clear preference guidance on locator strategy (role+name over css) and flags the class of controls that will abort, but says nothing about when to reach for this over siblings like browser_type or browser_run, nor prerequisites such as the tab needing to be open.

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