Starting Devin for Terminal

By default, sessions happen in a REPL, a graphical terminal interface where you can chat back and forth and observe Devin’s actions. 
devin                           # Start interactive REPL (no prompt)
devin -- your prompt here        # Start REPL with initial prompt
devin -p -- "prompt"            # Single-turn, no REPL: print response to stdout and exits
Use -- before your prompt so it is interpreted as a prompt and not a subcommand.
Single-turn mode (-p) is great for scripts and automations.
Type @ in the prompt input to open autocomplete for local files/directories. Selecting one adds it as context for your message.

​
Modes

Devin for Terminal supports 3 built-in modes: Normal, Plan, and Bypass.

Normal

Auto-approves read-only tools, asks for permission for write/execute operations.
/normal
# or
/mode normal
This is the default mode.
Planning-only mode. The agent excels at creating detailed, code-grounded implementation plans. It has access to all tools but doesn’t make changes.
/plan
# or
/mode plan
Auto-approves all tool calls, including writes and shell commands.
/bypass
# or
/mode bypass
You can also start in bypass mode:
devin --permission-mode bypass
Aliases: /yolo, /dangerous

​
Session History

Your conversation history is saved so you can resume a session later. 
devin -c              # Continue the most recent session in the current directory
devin --continue

devin -r              # Pick from recent sessions
devin --resume
