effect-uai-pause-resume

To pause an agent loop without holding provider calls, use a latch to block streamTurn initiation before each iteration. Closing the latch stops new HTTP connections from being held during the pause. Opening the latch resumes the body.

State threads through the loop naturally, so resume returns to the exact point of pause. No checkpoint needs to be written because state continuity is maintained internally within the loop body.

Yes, soft pause and resume is applicable for rate-limit cooldowns, manual UI pauses, and scheduled gating. The latch gates the loop iteration based on your specific timing requirements without dropping state.

Yes, implementing this soft pause-resume requires the Effect library, Latch primitives, and core loop utilities. These dependencies provide the concurrency structures needed to gate the loop body iterations.

Using a latch primitive is the best way to gate an in-flight agent loop between turns. The loop body waits on the latch before each iteration, providing fine-grained lifecycle control without losing state.
