How do you keep an agent's commits small enough to actually review?
A developer describes challenges in reviewing multi-turn agent sessions, particularly when using tools like GPT-6 Astra and MiniMax Code for refactoring. They encountered an issue where an early-turn call no longer matched a signature changed in a later turn, only discovered when tests failed. The developer notes that while individual turns were consistent, the inconsistency arose between them. They also highlight the difficulty of determining commit boundaries during an agent's session without interrupting its thought process, despite tools like MiniMax Code driving browser interactions for documentation and issue threads.
This report uniquely details a specific failure mode where an agent's early-turn call no longer matched a signature changed in a later turn, unlike general discussions on agent commit sizes.

Last week I had a multi-turn agent session on a small refactor. I read each turn as it landed and had no objection. At commit time an early-turn call no longer matched a signature a later turn had changed. I only found out because the tests failed.
Each turn was consistent on its own, but the break sat between them where neither turn showed it. Since GPT-6 Astra went wide, how to review this stuff keeps coming up. I ran out of Codex usage mid-task. Codex still had the plan, so I kept that half there. I fed each step to MiniMax Code, held it to the plan, read what came back turn by turn. While MiniMax Code worked a step it drove the browser too, docs and the issue thread in separate tabs instead of me pasting between them.
After the scare I scoped my review to the last turn. The diff mixes in my edits but a single turn is just what the agent wrote since I last read. That caught a fallthrough where it removed a guard the next branch needed. Anything touching auth still gets read line by line.
A few days on one codebase is not much to go on. Whatever I run is a first pass.
Where do you draw the commit boundary when the agent is mid-session and the work isn't done? Every time I've tried checkpointing I end up interrupting it mid-thought.
