browser_pause_clock

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

With no annotations, the description carries full responsibility for disclosing behavioral traits. It provides none: no explanation of what pausing the clock does to timers, whether a clock must have been installed first, or whether this affects other browser operations. The description is completely opaque.

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 extremely concise, consisting of a single phrase. However, it is under-specified rather than appropriately sized; a few words clarifying the effect or usage context would be more valuable. It earns a middle score for brevity but not for informative structure.

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?

Given the lack of annotations, output schema, and parameter details, the description must compensate by providing operational context. It fails to do so, leaving the agent without sufficient understanding of the tool's role in clock management or its side effects.

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 tool has zero parameters, so the schema provides no information to supplement. The baseline for 0-parameter tools is 4, and the description does not detract from this, even though it offers no additional semantic value.

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 '暂停时钟' is a direct translation of the tool name 'browser_pause_clock', essentially restating the title without additional context. It does convey the action (pause) and resource (clock), but it is a tautology, offering no new information beyond the name itself.

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 on when to use this tool versus alternatives such as browser_fast_forward or browser_resume_clock. The description simply states the action, with no mention of prerequisites, typical use cases, or relationship to sibling clock-management tools.

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