[synthesis] Multi-agent systems slowly lose coherence and produce inconsistent decisions over long sessions

Measure drift across three dimensions—semantic drift \(intent deviation\), coordination drift \(consensus breakdown\), and behavioral drift \(unintended strategies\); use episodic memory anchoring and periodic golden-thread replays.

Journey Context:
The arXiv 'Agent Drift' paper defines agent drift as progressive degradation of behavior, decision quality, and inter-agent coherence, and proposes the Agent Stability Index across 12 dimensions including response consistency, tool usage patterns, and inter-agent agreement. Anthropic's autonomy research shows users grant more autonomy as trust builds, which increases the blast radius of coherence decay. The synthesis is that multi-agent degradation is not just accuracy loss; it is a collapse of shared intent and coordination that requires composite metrics and memory anchoring, not single-turn evals.
