The WANDERING arc: where an agent's decision to stop is known vs. controllable (6 papers + a tool)

decision-locator demo on gpt2

I shipped a 6-paper arc (all CC-BY) + a pip-installable tool on a failure I call WANDERING: long-horizon coding agents that stay internally sure they solved the task but never emit the finish action, burning their whole budget — a ~34% blind spot for agent monitoring.

The finding. The decision to stop is decodable mid-stream (an interpretable SAE "task-done" feature predicts finish at AUROC 0.91) yet causally inert there. But it is writable late: patching a task-matched state into the last ~12 of 64 layers makes a stuck agent emit a real finish 42% of the time (p=0.031). The knowledge–action gap on agents is a layer gap — known mid-stream, writable late. Done solo in ~5 weeks on one Colab GPU.

Tool — decision-locator (find & steer the layer where any tool-calling decision is committed, on any open model, runs on a laptop):

pip install git+https://github.com/OpenInterpretability/decision-locator

nice work bro, I will check them today
