Handoff Friction

The failure mode that occurs at system integration points when an agent encounters an unexpected data format or schema from a receiving system and attempts to resolve the mismatch autonomously rather than reporting it — producing a hallucinated fix that propagates through the workflow as correct data.

Extended Definition​

Handoff Friction is the second of three primary failure modes in autonomous systems, and the one most often inherited from the incumbent architecture rather than generated by the agentic system itself. It does not originate in the agent's logic. It originates in the gap between what the agent expects at a handoff point and what the legacy or third-party system actually returns. Traditional automation handles this with hard-coded integrations that fail loudly when the schema changes. Agentic systems are more capable — and more dangerous. A capable agent will attempt to bridge the gap rather than halt. The result is a hallucinated resolution that the system treats as valid data and passes downstream, where it compounds silently across the workflow.

  • Deterministic Failure — Handoff Friction should be resolved through Deterministic Failure design: the agent halts and escalates at the schema mismatch rather than attempting an autonomous fix that propagates as valid data.
  • Context Leakage — Handoff Friction and Context Leakage produce similar downstream effects — incorrect data propagating silently — but Handoff Friction originates at integration boundaries while Context Leakage originates in accumulated task-level drift.
  • Legacy Liability — Handoff Friction is most severe at legacy integration points: the schema mismatches that trigger it are typically inherited from incumbent systems that were not designed for agentic consumption.
  • Logic Decay — Both Handoff Friction and Logic Decay compound silently before producing visible failures; the difference is that Handoff Friction originates at integration points while Logic Decay originates in environmental data drift.
