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

With no annotations, the description carries the full burden of describing behavior, but it merely restates the action. It does not disclose waiting semantics, what happens if the element is not found, whether the element must be visible, or what the return value is.

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 with no wasted words, so it is concise. However, it is so terse that it borders on under-specification rather than being usefully information-dense.

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 schema covers the parameters well, but the description omits behavioral context that an agent needs, such as whether the tool waits for the element, what locator strategies are preferred, and what to do when the element is not found. For a browser automation tool with no output schema and no annotations, this is a significant gap.

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?

All three parameters have schema descriptions, so the 100% schema coverage sets the baseline at 3. The description adds no extra parameter semantics, but it does not need to because the schema already documents selector, by, and timeout clearly.

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 the core action clearly: it clicks on an element. It is short but unambiguous, with a concrete verb and object. However, it does not distinguish this tool from sibling interaction tools like double_click, right_click, or hover beyond the tool name.

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 no guidance on when to use this tool versus alternatives such as execute_script, send_keys, or hover. It also does not mention prerequisites like needing an active browser session, element visibility, or how to choose between locator strategies.

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