browser_trace_stop

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

No annotations are provided, so the description carries full responsibility. It states the tool stops the session and returns data, which is sufficient for basic understanding. However, it does not disclose potential side effects (e.g., whether ongoing events are discarded) or behavior when no trace is active.

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, front-loaded, and contains no extraneous information. Every word earns its place.

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 with no parameters and no output schema, the description is largely complete. It covers the action and result. A minor missing detail is the prerequisite of an active trace, but this is implied. Overall, the agent can select and invoke the tool correctly with this information.

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 no parameters (0 params, 100% coverage). According to guidelines, baseline is 4. The description correctly does not add parameter information since none exist.

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 clearly states the tool stops a browser tracing session and returns collected data. It uses a specific verb ('stop') and identifies the resource ('browser tracing session'), making it unambiguous despite being in Chinese. The sibling tools include 'browser_trace_start' and 'browser_trace_chain', so this complements them clearly.

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 explicit guidance on when to use this tool versus alternatives. It implies it should be used after starting a trace, but does not state prerequisites or when not to use it. The context is implied from the name and description, but not explicit.

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