I Read 31 Agent Loops — Most Stop When They're Tired, Not When They're Right
The problem, stated plainly: most agent loops don't know when to stop. They stop when they run out of turns, when they hit a wall they can't get past, or when a human finally looks — and then they call whatever state they're in "done." Repeating is the easy part. Knowing the latest pass is actually right — and not just the pass you happened to be on when the budget ran out — is the whole game.
This week the loop became a named, shareable artifact — a library you can browse, copy, and submit to. But the names aren't the interesting part. The exits are. Here's what changed my mind, the four ways a loop can stop ranked by how much trust each one earns, and why — now that generation is nearly free — the exit is the only part left worth engineering.
