Truncated Batch Tool Calls Corrupt Agent State; Paper Proposes Transaction Admission Control
Flunder707 · reddit · 2026-07-31
The author discovered that when a model hits its output limit mid-response, batched tool calls get truncated—causing some operations to execute while others are lost, leaving corrupted history.
Fuzz testing across 107 truncation positions confirmed that nearly all produce partial side effects. The proposed solution validates the entire batch before executing any call (transaction admission control), reducing partial execution to zero. Paper and code are open-sourced.
