browser_mouse_click

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

With no annotations, the description carries the full burden of behavioral disclosure. '鼠标点击坐标' says nothing about which mouse button is used, whether the move is instant, what happens with invalid coordinates, or any return value. It is almost entirely silent on behavior.

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 short phrase, which might seem concise but is actually under-specification. It omits critical information and does not earn its place as a useful description; it is too terse to be effective.

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 tool that performs a visible user interaction and has no annotations or output schema, the description is severely incomplete. It fails to explain the action, parameters, side effects, or interaction with other browser tools, making it inadequate for an AI agent to use reliably.

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?

The input schema has two number parameters with 0% schema description coverage. The description merely labels them as 'coordinates' without explaining the coordinate system (viewport vs page), units, or how to determine the correct values. It adds only minimal semantic value beyond the schema.

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 '鼠标点击坐标' (mouse click coordinates) is a noun fragment that implies clicking at a coordinate but does not explicitly state the action. It does not distinguish the tool from siblings like browser_click or browser_mouse_down/up, which have different semantics.

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 guidance about when to use this tool vs alternatives such as browser_click for element clicks or browser_mouse_move for hovering. The description provides no context, prerequisites, or exclusion criteria.

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