From the Daily Brief

Many agent harnesses wrap work in a loop that repeats until a check passes. This preprint formalizes that pattern as three parts: the worker, a gate the worker cannot modify, and a budget declared before the run. Under those conditions the authors prove the loop terminates even when it includes repair steps. They measure gate quality with mutant corpora, deliberately broken outputs that a working gate should reject. Applied to 69 loops found in shipped systems, the audit flagged 47 vacuous gates, checks that pass regardless of the work. The practical design they propose is an independent gate, a global repair budget and a spending ceiling set before the run starts. If your agent's definition of done is a test or validator it can edit, or one that never fails, the loop's guarantees are weaker than they look.

Context

An saying it has finished is a weak completion check. Bounded Loops proposes separating the worker from a checker it cannot modify, with a declared budget governing attempts and repairs. Completion requires the checker's recorded approval, while spending limits apply during an attempt.

The checker itself still needs testing. The authors report that checks which rejected every deliberately broken example in one test collection accepted failures from a fresh collection. The useful contribution is a way to control execution and examine completion checks, rather than treating an agent's confidence or an exhausted test set as proof of success.
