Features
Steering while busy
Send context updates into an in-flight turn when the backend supports steering.
Happier supports in-flight steering for compatible runtimes.
Steering means you can send a new user message without interrupting the current turn. The message is injected as extra context while the agent is still working.
When steering applies
Steering is used only when all conditions are true:
- the current backend/runtime advertises steering support,
- the session is online and agent-ready,
- a turn is currently in flight,
- your send policy is set to steer while busy.
If these conditions are not met, Happier falls back to normal pending-queue behavior.
Busy-session send policy
In the app, open:
- Settings
- Session
- Message sending
- When the agent is busy (steer-capable)
You can choose:
- Steer immediately: send immediately and steer the active turn.
- Server pending: store message in pending queue first.
Interaction with pending queue
Steering and pending queue are complementary:
- Use steering for quick context corrections while the turn is running.
- Use pending queue when you want ordered, editable messages before execution.
If steer fails for any reason, Happier uses queue fallback so messages are not lost.
