browser_get_title

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

The description is just the action phrase with no behavioral disclosure. It does not mention that the tool operates on the current page, what happens if no page is loaded, or the return format. Since no annotations are provided, the description carries the full burden and fails to provide any transparency.

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 with no structure, but it is concise. However, it is under-specified and provides little value beyond the tool name, so it does not earn a higher score for appropriate sizing and front-loading.

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?

Even for a simple getter, the description lacks essential context such as return value, current page assumption, and error behavior. Without an output schema or annotations, this is insufficient for an agent to use the tool confidently, making the description incomplete.

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 zero parameters, so there is nothing to document. The baseline for zero-parameter tools is 4, and the description does not need to add parameter semantics because no parameters 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 '获取页面标题' directly restates the tool name (browser_get_title) in Chinese, offering no additional specificity or differentiation from sibling getter tools. It is essentially a tautology, not a clear purpose statement that distinguishes the tool from others like browser_get_text or browser_get_current_url.

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 guidance is provided about when to use this tool versus alternatives. The description does not mention any context, prerequisites, or exclusion conditions, leaving the agent without direction on when to select this tool over similar getters.

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