SummaryCHILL-Harness is a method for adaptive orchestration in LLM agent harnesses that uses counterfactual causal learning. It estimates workflow advantage from confidence-weighted execution evidence and selectively applies only adjustments with sufficient expected benefit, reducing token use and execution time while preserving task success across long-horizon tasks.
Why it mattersFrames harness adaptation as causal intervention rather than fixed policy, with reported token and time reductions on long-horizon benchmarks. Relevant if you build or tune agent systems.
