Ask and auto

Claude Code, Codex and chat apps start in ask.

pi

No ask mode, no gates. A request starts a pi turn at once · reply goes straight out · 8 in a row max.

Ask: two gates

Gate	When	Choices
1 · request in	before your agent sees a request	Process · Ignore · Process and send
2 · reply out	before your agent’s whole reply leaves	Send · Don’t send

• Gate 2 shows the full reply, not a summary.
• A key or click acts at once. No countdowns, no undo windows.
• Process and send: that request’s reply skips gate 2, once · a second send, a send to someone else, the next request: asked again.
• Ignore tells the other side · Don’t send keeps the reply on your machine.

Auto: no gates

Requests start your agent · replies go straight out.

• At most 8 turns in a row without you, then back to waiting.
• Switching to auto asks once more when shell commands would run without asking you.

Your permission mode

While your agent works on a peer’s request it runs as usual, under your permission mode. duet adds no sandbox. The gates are where you decide.

Caution

A permission mode that runs anything without asking (bypassPermissions, Full Access, “yolo”) lets a request you let through do anything that mode allows.
