HECE protocol offers forensic debugging for AI agent incidents
Developer Israel Henriques introduces HECE (Hypothesize, Evidence, Check, Eliminate), a forensic protocol for diagnosing AI agent failures. The method involves listing all possible causes, defining evidence signatures for each, then systematically checking and eliminating hypotheses. Henriques successfully used HECE to debug his own agent after an April 17 incident, ruling out four of six hypotheses.

While HECE is a practical, no-nonsense approach to AI agent debugging, its reliance on developer discipline may limit adoption in teams that prefer automated monitoring tools.
