An agent-loop guide says good systems need eight separate exit conditions
blaizedsouza · x · 2026-07-21
The post shares a framework for agent loops that uses eight separate exit conditions instead of relying on a single stop signal.
The visible examples include:
- goal met: an evaluator scores the output against a rubric and stops the run on pass
- turn cap: a hard maximum on iterations, enforced by the harness
- budget cap: a token or dollar limit
- wall clock: a real deadline
- no progress: hash the state each turn and stop after repeated identical states
The quoted article argues that the best agent engineers stopped writing better prompts and started writing better loops.
