 The Docker image supports both AMD64 and ARM64 architectures. The GitHub CLI and Claude CLI are automatically downloaded for the correct architecture during build.
 
-##### Playwright for Automated Testing
-
-The Docker image includes **Playwright Chromium pre-installed** for AI agent verification tests. When agents implement features in automated testing mode, they use Playwright to verify the implementation works correctly.
-
-**No additional setup required** - Playwright verification works out of the box.
-
-#### Optional: Persist browsers for manual updates
-
-By default, Playwright Chromium is pre-installed in the Docker image. If you need to manually update browsers or want to persist browser installations across container restarts (not image rebuilds), you can mount a volume.
-
-**Important:** When you first add this volume mount to an existing setup, the empty volume will override the pre-installed browsers. You must re-install them:
-
-```bash
-# After adding the volume mount for the first time
-docker exec --user automaker -w /app automaker-server npx playwright install chromium
-```
-
-Add this to your `docker-compose.override.yml`:
-
-```yaml
-services:
-  server:
-    volumes:
-      - playwright-cache:/home/automaker/.cache/ms-playwright
-
-volumes:
-  playwright-cache:
-    name: automaker-playwright-cache
-```
-
-**Updating browsers manually:**
-
-```bash
-docker exec --user automaker -w /app automaker-server npx playwright install chromium
-```
