Implementation Reference

  • Handler implementation for the browser_navigate tool. Navigates the Playwright page to the specified URL and returns a success message.
    case ToolName.BrowserNavigate:
      await page.goto(args.url);
      return {
        content: [{
          type: "text",
            text: `Navigated to ${args.url}`,
          }],
        isError: false,
      };
  • Input schema for browser_navigate tool, defining a required 'url' string property.
    inputSchema: {
      type: "object",
      properties: {
        url: { type: "string" },
      },
      required: ["url"],
    },
  • index.ts:39-49 (registration)
    Registration of the browser_navigate tool in the TOOLS array, including name, description, and schema.
    {
      name: ToolName.BrowserNavigate,
      description: "Navigate to a URL",
      inputSchema: {
        type: "object",
        properties: {
          url: { type: "string" },
        },
        required: ["url"],
      },
    },
  • index.ts:23-23 (registration)
    Enum definition mapping ToolName.BrowserNavigate to the string 'browser_navigate'.
    BrowserNavigate = "browser_navigate",
Behavior2/5

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

With no annotations provided, the description carries full burden but only states the basic action. It doesn't disclose behavioral traits such as whether navigation is synchronous/asynchronous, error handling, timeout behavior, or interaction with browser state, which are critical for a navigation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise with a single sentence ('Navigate to a URL'), front-loaded and zero waste. Every word earns its place, making it efficient for quick understanding.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (navigation in a browser context), lack of annotations, no output schema, and low schema coverage, the description is incomplete. It misses details on return values, error cases, and integration with sibling tools, making it inadequate for effective use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate but adds no meaning beyond the schema. It doesn't explain the 'url' parameter's format, constraints, or examples, leaving the agent with only the schema's basic type information.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Navigate') and target ('to a URL'), providing a specific verb+resource combination. However, it doesn't distinguish this from sibling tools like 'browser_url_reflected_xss' or 'browser_url_sql_injection' which also involve URL operations, missing explicit differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, context for navigation, or compare it to sibling tools like 'browser_click' or 'browser_evaluate', leaving the agent with no usage direction.

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