+### SSH Passphrase Best Practices
+
+When using GitHub mode with SSH authentication, it's important to properly manage SSH key passphrases to ensure automation works smoothly:
+
+1. **Use SSH Agent**: Configure ssh-agent to remember your passphrase, so you don't need to enter it repeatedly:
+
+   ```bash
+   # Start the ssh-agent in the background
+   eval "$(ssh-agent -s)"
+   
+   # Add your SSH private key to the ssh-agent
+   ssh-add ~/.ssh/id_ed25519  # Replace with your key path
+   ```
+
+2. **Configure SSH Agent to Persist**:
+   - On macOS, you can use the keychain to remember your passphrase:
+     ```bash
+     ssh-add --apple-use-keychain ~/.ssh/id_ed25519
+     ```
+   - On other systems, consider using tools like `keychain` or configuring your desktop environment to start ssh-agent automatically
+
+3. **Create Config File** (optional): Create or edit `~/.ssh/config` to use the ssh-agent:
+   ```
+   Host github.com
+     AddKeysToAgent yes
+     UseKeychain yes  # macOS only
+     IdentityFile ~/.ssh/id_ed25519
+   ```
+
+Without proper SSH agent configuration, MyCoder may be interrupted by passphrase prompts during Git operations, which can cause timeouts in automated environments.
