arXiv 2607.13285, 154 upvotes on HuggingFace Daily, argues that "behavior localization is therefore a central bottleneck in harness evolution." It proposes an automated behavior-centric map built from static analysis plus LLM assistance linking each behavior to its source, plus Behavior-Guided Progressive Disclosure, which walks agents down a behavioral hierarchy while verifying candidate code locations. Reported gains in planning efficiency for scattered code sites and cross-module interactions, at fewer tokens. If you run a self-improving harness, this is the paper of the week.
