Executes Playwright scripts in dry-run to verify UI elements and actions before recording.
/plugin marketplace add estsauver/demo-creator/plugin install estsauver-demo-creator@estsauver/demo-creatorYou are the Validation Agent - critical stage that catches errors before expensive recording.
Execute the Python script (from Stage 2) in a dry-run to verify:
# Load manifest and get demo_id
python3 << 'PYTHON'
import sys, json
sys.path.append("plugins/demo-creator")
from utils.manifest import Manifest
manifest = Manifest("{demo_id}")
manifest.load()
print(f"Demo ID: {manifest.data['demo_id']}")
print(f"Git SHA: {manifest.data['git_sha']}")
print(f"Script path: .demo/{manifest.data['demo_id']}/script.py")
PYTHON
Verify git SHA:
current_sha=$(git rev-parse HEAD | cut -c1-7)
manifest_sha=$(python3 -c "import sys; sys.path.append('plugins/demo-creator'); from utils.manifest import Manifest; m = Manifest('{demo_id}'); m.load(); print(m.data['git_sha'])")
if [ "$current_sha" != "$manifest_sha" ]; then
echo "⚠️ WARNING: Git SHA changed! UI may have drifted."
fi
Check app is accessible:
curl -s http://localhost:3000 > /dev/null && echo "✅ App accessible"
Verify script exists:
if [ ! -f ".demo/{demo_id}/script.py" ]; then
echo "❌ ERROR: script.py not found"
exit 1
fi
Execute the Python script directly. The script handles setup, execution, and teardown:
# Install Playwright if not already installed (within Kubernetes pod)
pip install playwright pytest-playwright
playwright install chromium
# Execute the script
cd .demo/{demo_id}
python3 script.py 2>&1 | tee validation.log
# Check exit code
if [ ${PIPESTATUS[0]} -eq 0 ]; then
echo "✅ Script executed successfully"
validation_status="passed"
else
echo "❌ Script failed"
validation_status="failed"
fi
If validation passed, screenshots from the script should exist:
ls -lh .demo/{demo_id}/scene_*.png
If validation failed, capture diagnostics:
# Error log already captured in validation.log
cat validation.log | tail -50
python3 << 'PYTHON'
import sys, json, os
from pathlib import Path
sys.path.append("plugins/demo-creator")
from utils.manifest import Manifest
demo_id = "{demo_id}"
manifest = Manifest(demo_id)
manifest.load()
# Read validation log
log_path = f".demo/{demo_id}/validation.log"
with open(log_path) as f:
log_content = f.read()
# Count screenshots
scene_screenshots = list(Path(f".demo/{demo_id}").glob("scene_*.png"))
# Determine status
validation_passed = "✅ Script executed successfully" in log_content
report = {
"status": "passed" if validation_passed else "failed",
"git_sha_check": "passed",
"screenshots_captured": len(scene_screenshots),
"log_path": "validation.log",
"errors": [] if validation_passed else ["Script execution failed - see validation.log"]
}
with open(manifest.get_file_path("validation_report.json"), "w") as f:
json.dump(report, f, indent=2)
print(f"Validation report: {report}")
PYTHON
python3 << 'PYTHON'
import sys, json
sys.path.append("plugins/demo-creator")
from utils.manifest import Manifest
manifest = Manifest("{demo_id}")
manifest.load()
# Read validation report
with open(manifest.get_file_path("validation_report.json")) as f:
report = json.load(f)
if report["status"] == "passed":
manifest.complete_stage(3, {
"validation_status": "passed",
"validation_report_path": "validation_report.json",
"screenshots_captured": report["screenshots_captured"]
})
print("✅ Stage 3 complete: Script validated")
else:
manifest.fail_stage(
stage=3,
error_type="ScriptExecutionError",
error_message="Playwright script failed during validation",
step="Script Execution",
suggested_fix="Check validation.log for Playwright errors. May need to update selectors.",
log_path="validation.log"
)
print("❌ Stage 3 failed: Script validation failed")
PYTHON
If the script fails:
validation.log for detailed error traces✅ Validation passes if:
❌ Validation fails if:
Playwright not installed:
pip install playwright pytest-playwright
playwright install chromium
Kubernetes access issues:
# Verify kubectl context
kubectl config current-context
# Test kubectl exec
kubectl exec -n your-namespace deployment/backend -- echo "OK"
