Workflow Integration

With agent-browser

# Start a session with agent-browser
agent-browser --session myapp open https://example.com
agent-browser --session myapp state save ./session.json

# Hand off to sensitive-browser for login
npx sensitive-browser "log in with credentials" \
  --state ./session.json \
  --sensitive-data ./creds.json

# Continue with agent-browser
agent-browser --session myapp state load ./session.json
agent-browser --session myapp snapshot

Standalone

npx sensitive-browser "fill out the checkout form with payment info" \
  --url https://store.example.com/checkout \
  --sensitive-data ./payment.json \
