How mcp_servers changes the session overlay; default replace. Append preserves other servers and credentials. Duplicate names are refused except renewal of an owned, revoked browser/screen reach with a live reach of the same kind in the same Task.

Seconds this session's machine stays awake after a turn ends before it is paused (60-86400; omitted = the platform default of 60). A paused machine wakes on the next message; apps the agent serves on exposed ports are unreachable while it is paused, so set this to how long people keep using them after the agent finishes; null clears back to the platform default. Applies from the next time the session goes idle

Switch this session's model (a current model for its harness; the agent's model is unchanged). Applies from the next turn

Session-level reasoning effort; null clears to the agent's setting normalized for the target model. Applies from the next turn.

After every subscription account is exhausted, continue on the same model using the paid platform API; wallet and session budget still apply

Who pays for model calls; switching restarts the agent's engine in place
