[synthesis] Partially correct agent output creates inconsistent state harder to recover from than complete failure

Design agent operations to be atomic: either fully succeed or fully roll back. Implement state checkpoints before each agent action. When validation fails, roll back to the last known-good checkpoint rather than attempting partial fixes. Prefer operations that crash loudly over operations that silently partially succeed.

Journey Context:
Complete failures are actually safer than partial successes. When an agent's output is 0% correct, the system is in a known-bad state that triggers a clean retry from a checkpoint. When it's 95% correct, some state changes persist while others don't, creating an inconsistent state that's harder to detect and fix. The agent sees partial success as confirmation and continues, building on corrupted foundations. The synthesis: combining ACID transaction principles with the observation that LLMs rarely produce completely wrong output for well-specified tasks reveals that the most common and most dangerous agent failure mode is partial success, not total failure. Yet most agent frameworks only handle total failures \(via retry logic\). The gap is handling partial success, which requires atomic operations and rollback—patterns from database theory that haven't been adopted in agent frameworks. LangGraph's checkpointing is a step in this direction but doesn't enforce atomicity. The key insight: you must design for partial success from the start, because it's the default failure mode of LLM agents, and it's the one that compounds most catastrophically.
