When "Must" Becomes "Maybe": Constraint Weakening in LLM Agent Workflows
Abstract
Multi-stage LLM workflows lose operational constraints when intermediate artifacts transform binding prerequisites into non-binding context, causing safety failures despite preserved content.
Large language model (LLM) agents coordinate complex tasks through multi-role and multi-stage workflows. Upstream state is repeatedly transformed into intermediate language artifacts, such as summaries, plans, tickets, memories, and handoff notes, from which downstream components act. For action-constraining state, topical retention is insufficient: an artifact may mention an unresolved condition while changing it from a requirement that must be resolved before execution into information that may merely inform the next action. We study this action-binding role as operational state preservation. Safety blockers provide a controlled instance because each source state has an explicit prerequisite, authority, fallback, and execution consequence. We condition on correct upstream identification, vary the handoff transformation, and evaluate an executor restricted to the resulting artifact. Across 1,296 controlled synthetic episodes, direct-handoff controls preserve every blocker, whereas compression, plan assimilation, convergence, ownership deferral, and precedent substitution repeatedly turn binding state into caveats or non-binding considerations. Normal handoff compression produces 100.0% deactivation and 54.2% forbidden action. Restoring all four state fields raises preservation to 100.0% and reduces forbidden action to 0.0%. Fixed-artifact interventions further separate preservation from containment: downstream verification eliminates forbidden action while artifact deactivation remains 95.3%. These results identify a state-transmission failure between information extraction and action. Handoff transformations can retain state content while weakening its constraints on downstream action. Semantic availability does not guarantee operational preservation.

Most evaluations of agent memory and handoffs ask whether information survives. We ask a different question: does it still constrain downstream action?
We introduce operational state preservation—the requirement that action-constraining state remain binding, rather than merely semantically available, as it passes through summaries, plans, tickets, memories, and handoff notes. Across 1,296 controlled episodes, ordinary handoff compression turns unresolved blockers into non-binding caveats, producing 100.0% deactivation and 54.2% forbidden action. Restoring four explicit state fields recovers preservation, while downstream verification only contains the resulting failures.
Semantic retention is not operational preservation.
