Implementation Reference

  • The switch case that implements the core logic for the 'puppeteer_navigate' tool: navigates the Puppeteer page to the specified URL and returns a success response.
    case "puppeteer_navigate":
      await page.goto(args.url);
      return {
        content: [{
          type: "text",
          text: `Navigated to ${args.url}`,
        }],
        isError: false,
      };
  • The input schema for the 'puppeteer_navigate' tool, defining a required 'url' property of type string.
    inputSchema: {
      type: "object",
      properties: {
        url: { type: "string" },
      },
      required: ["url"],
    },
  • index.ts:103-113 (registration)
    The tool registration object in the TOOLS array that defines the name, description, and schema for 'puppeteer_navigate', used by the ListToolsRequestSchema handler.
    {
      name: "puppeteer_navigate",
      description: "Navigate to a URL",
      inputSchema: {
        type: "object",
        properties: {
          url: { type: "string" },
        },
        required: ["url"],
      },
    },
  • index.ts:447-449 (registration)
    The server request handler for listing tools, which returns the TOOLS array including 'puppeteer_navigate'.
    server.setRequestHandler(ListToolsRequestSchema, async () => ({
      tools: TOOLS,
    }));
  • index.ts:451-451 (registration)
    The server request handler for calling tools, which dispatches to handleToolCall based on the tool name, routing 'puppeteer_navigate' to its implementation.
    server.setRequestHandler(CallToolRequestSchema, async (request) => handleToolCall(request.params.name, request.params.arguments ?? {}));

TDQS

B3.3/5.0
Behavior2/5

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

No annotations are provided, and the description does not disclose behavioral traits such as whether the tool waits for page load, handles errors, or returns navigation status. For a navigation action, these details are important.

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 a single, concise sentence that communicates the core functionality without redundancy. It is appropriately sized and front-loaded.

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

Completeness3/5

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

Given the tool's simplicity and the absence of an output schema, the description is minimally adequate but lacks completeness. It does not mention return values, timeout behavior, or prerequisites (e.g., an active page).

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

Parameters3/5

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

The description implies that the 'url' parameter is the target URL for navigation, adding basic meaning beyond the schema. However, with 0% schema description coverage, more detail (e.g., format, allowed protocols) would be beneficial.

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

Purpose5/5

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

The description 'Navigate to a URL' clearly states the action (navigate) and the resource (URL). It distinguishes from sibling tools like puppeteer_screenshot or puppeteer_click, which perform different actions.

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?

No guidance is provided on when to use this tool versus alternatives such as puppeteer_connect_active_tab. The description lacks context for appropriate usage scenarios.

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