The agent detects the user's environment and provides tailored instructions, but **never asks for or handles credentials** — users add those directly to their shell profile in Step 5. Make this clear to the user whenever credentials come up in Steps 3a and 3b. ## Step 1: Check Existing Configuration Before starting the setup, check if the user already has the required environment variables configured. Run this command to check for existing c...
