browser_click

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

With no annotations, the description carries the full burden, but 'Click element' only names the action. It does not disclose that clicking may trigger navigation, page changes, or side effects, nor does it mention waiting behavior, prerequisites, or result of the click. It supplies almost no behavioral context beyond the action itself.

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 only two words, so it has no fluff, but it is under-specified rather than efficiently concise. It front-loads nothing of substance beyond repeating the tool name and object. A genuinely effective description would pack at least usage or behavioral guidance into the space.

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 browser interaction tool with five parameters, no annotations, and no output schema, this description is inadequate. The schema covers parameter names but not when to use the tool, what happens after the click, or how to handle clicks that cause navigation. It leaves the agent to guess important invocation context.

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 80% schema description coverage, the schema already explains most parameters (ref, button, element, doubleClick). The description adds nothing about how parameters interact, but the high schema coverage means this is acceptable at baseline. It does not compensate for the one parameter without a description (modifiers), but the enum values provide some meaning.

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 clear verb ('Click') and resource ('element'), so an agent knows the tool performs a click action. However, it does not mention optional behaviors like double-click or button choice, and it does nothing to distinguish itself from sibling interaction tools like browser_hover, so it misses the specificity needed for a 5.

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?

No usage context is provided. The description does not state when clicking is appropriate versus hovering, typing, pressing a key, or filling a form, and it offers no alternatives or exclusions. An agent must infer usage from the tool name alone.

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