All 8 browser tools unusable: no browser binary bootstrap or system-browser fallback #9

Open

Description

@Mnehmos

All 8 browser tools (launch_browser, navigate_page, get_page_content, screenshot_page, click_element, type_text, evaluate_js, get_console_logs) are unusable on a clean install.

Repro

launch_browser(headless: true)
-> browserType.launch: Executable doesn't exist at
   ...ms-playwright\chromium_headless_shell-1200\...
   Please run: npx playwright install

launch_browser(engine: "puppeteer", headless: true)
-> Could not find Chrome (ver. 143.0.7499.40).
   npx puppeteer browsers install chrome-headless-shell

Context

The audit log shows 65 historical evaluate_js and 28 screenshot_page calls, so this worked at some point and regressed when a browser cache was invalidated by a dependency bump. puppeteer and playwright are hard dependencies in package.json, yet nothing downloads a browser binary.

Fix

  1. Fall back to a locally installed system browser (Chrome / Edge) via Puppeteer channel or an explicit executablePath before failing.
  2. Surface an actionable error naming the exact install command when no browser can be found.
  3. Add a browsers:install npm script so the bootstrap is one documented command.
