Instructions

Implementation Reference

• src/tools/navigate.ts:60-73 (handler)

  The handler function for the 'browser_navigate_back' tool. It ensures a tab exists, calls `page.goBack()` to navigate back, generates corresponding Playwright code snippet, and returns it with snapshot and network wait instructions.
  handle: async context => { const tab = await context.ensureTab(); await tab.page.goBack(); const code = [ `// Navigate back`, `await page.goBack();`, ]; return { code, captureSnapshot, waitForNetwork: false, }; },
• src/tools/navigate.ts:52-58 (schema)

  The schema definition for the 'browser_navigate_back' tool, including name, title, description, empty input schema using Zod, and 'readOnly' type.
  schema: { name: 'browser_navigate_back', title: 'Go back', description: 'Go back to the previous page', inputSchema: z.object({}), type: 'readOnly', },
• src/tools/navigate.ts:100-104 (registration)

  Registers the 'browser_navigate_back' tool (via goBack) in the array exported by the navigate module, which is later imported and spread into main tool lists.
  export default (captureSnapshot: boolean) => [ navigate(captureSnapshot), goBack(captureSnapshot), goForward(captureSnapshot), ];
