browser_refresh

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

The description does not disclose potential side effects (e.g., losing unsaved form data, triggering reload prompts) or the behavior when the page is not loaded. With no annotations, the description must cover these, but it is minimal.

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 concise sentence that communicates the core action. It is not overly verbose, though it could include a brief note about the session context.

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 simple tool with an output schema, the description is adequate but lacks context about state changes (e.g., page reload behavior) or error conditions (e.g., invalid session). It is minimally complete.

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 fully describes the single parameter (session_id) with a clear description. The tool description adds no extra semantic detail, so it meets the baseline for high schema coverage.

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 action ('Refresh') and the resource ('current page'), making the purpose evident. However, among siblings like browser_back and browser_forward, it does not differentiate further, so it lacks explicit differentiation.

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 on when to use this tool versus alternatives, such as reloading a page versus navigating to a URL. It does not mention prerequisites like an active session or page.

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