Grab the wheel.
Mid-run.

WHEN TO REACH FOR IT

Three reasons to take over.

⛔

Policy stop

The agent hit a guardrail — a spend cap, a PII rule, a low-confidence threshold. You approve, reject, or tweak and continue.

e.g. refund exceeds $500 cap
🔧

Stuck run

Agent looped on a bad tool output or hit a flaky API. Inject the right answer, skip the step, or restart from an earlier point.

e.g. Stripe 503 on retry 3
✎

Teach a new pattern

Edge case you've never seen. Resolve manually; Grain captures it as a golden trace and offers to add it to the agent's evals.

e.g. "I paid in JPY but..."
EVERY INTERVENTION · LOGGED

Taking over
leaves a trail.

Every pause, every injected value, every override is signed, timestamped, and attached to the run. Your compliance team sees exactly who did what, when.
