Agent Continuity Layer Cuts Token Use 49.4% and Recovery Time 60.8% in Interruption Tests

A developer on Reddit is building Infra, a provider-neutral continuity and control layer for AI agents, addressing the scenario where an agent completes a real-world action (e.g., a successful DB migration) but dies before recording it—leaving its successor unsure whether to repeat the action, assume completion, or burn tokens reconstructing state.

Infra keeps authoritative state outside the agent's context window and runtime: the delegated mandate, checkpoints, artifact lineage, approvals, evidence of completed external side effects, the next permitted action, and a continuation package for the successor.

In an internal benchmark of deliberately interrupted high-risk tasks, Infra completed 5/5 runs vs 4/5 for a strong written-handoff baseline, with 49.4% lower model-token use, 60.8% faster recovery, and 63.6% lower premium-model cost per successful outcome; full audit evidence was preserved in 5/5 Infra runs vs 0/5 baseline. The author admits limits: on a cheap, repeatable task Infra used 13.8% more tokens, so ordinary handoffs still make sense for short, reversible work. The layer targets long-lived agents that cross models/runtimes, delegate to sub-agents, produce side effects, or are expensive/unsafe to recover. Founding design partners are being recruited for a free, shadow-only pilot.
