- name: Hourly UI/UX audit with live screenshots
cron_expr: "11 * * * *"
prompt: |
Hourly UX audit of the live Molecule AI canvas. Prefer real screenshots;
if the container sandbox prevents Chromium (see #23), fall back to HTML
analysis and note the limitation in the deliverable.
Hourly UX audit of the live Molecule AI canvas. Take real screenshots
and analyse actual user flows. The runtime discovered a working Chromium
path that bypasses the missing-libglib issue; use it rather than the
bundled `playwright install --with-deps` path (which fails in our sandbox).
1. SETUP PLAYWRIGHT (best-effort — continue on failure):
pip install -q playwright 2>/dev/null || true
playwright install chromium --with-deps 2>/dev/null || \
playwright install chromium 2>/dev/null || true
1. SETUP BROWSER (proven-working recipe from Run 6, 2026-04-14):
# Install @sparticuz/chromium + puppeteer-core via npm if not present
# and reuse the NSS/NSPR libs bundled with Playwright's Firefox binary.
cd /tmp && [ -d uiux-browser ] || (mkdir uiux-browser && cd uiux-browser && \
npm init -y >/dev/null && npm install --quiet @sparticuz/chromium puppeteer-core 2>&1 | tail -3)
# Ensure Playwright's firefox is present (ships libnss3.so, libnspr4.so)
npx playwright install firefox 2>/dev/null || true
FIREFOX_LIBS=$(ls -d /home/agent/.cache/ms-playwright/firefox-*/firefox 2>/dev/null | head -1)
[ -z "$FIREFOX_LIBS" ] && FIREFOX_LIBS=$(ls -d /root/.cache/ms-playwright/firefox-*/firefox 2>/dev/null | head -1)
2. ATTEMPT SCREENSHOTS:
Write a small playwright script to http://host.docker.internal:3000
capturing: home / empty state, create-workspace modal, full canvas,
viewport at 1280px. If library deps are missing, skip to step 3 and
note "screenshots unavailable" in the PM report.
2. TAKE SCREENSHOTS against http://host.docker.internal:3000:
Write a small puppeteer script capturing: home/empty state, create-workspace
modal, full canvas, help dropdown, settings panel (open + detail), template
palette, mobile 375px, responsive 1280px. Save to /tmp/ux-screenshots/.
Invoke with:
LD_LIBRARY_PATH="$FIREFOX_LIBS" node /tmp/uiux-browser/capture.cjs
Then Read each PNG in /tmp/ux-screenshots/ to analyse with vision.
If the browser still won't launch, fall back to curl+HTML and note it.
3. HTML / CSS ANALYSIS (always runs):
- curl http://host.docker.internal:3000 — verify build ID / HTML size
