Implementation Reference
- src/tools/browser/interaction.ts:91-102 (handler)The FillTool.execute method implements the core logic of the 'playwright_fill' tool. It waits for the specified selector to appear, then uses Playwright's page.fill() to input the value into the element.
export class FillTool extends BrowserToolBase { /** * Execute the fill tool */ async execute(args: any, context: ToolContext): Promise<ToolResponse> { return this.safeExecute(context, async (page) => { await page.waitForSelector(args.selector); await page.fill(args.selector, args.value); return createSuccessResponse(`Filled ${args.selector} with: ${args.value}`); }); } } - src/tools.ts:149-160 (schema)Tool schema definition for 'playwright_fill', specifying name, description, and input schema requiring 'selector' and 'value' parameters.
