Report #68119

[frontier] Hardcoding human approval points makes agent workflows brittle and hard to audit.

Implement HITL as a Service: Define approval policies as declarative rules \(e.g., 'transactions >$1000 require approval'\). Use an event-driven step function \(Inngest waitForEvent, Temporal signals, or LangGraph Command.RESUME\) to pause agent execution. Store human decisions as structured audit logs that can be used for RLHF fine-tuning later.

Journey Context:
Early agents embed if-else checks for human approval, scattering business logic. HITLaaS treats human approval as an external service with SLAs. The key insight is separating the 'what' \(agent action\) from the 'whether' \(policy evaluation\). This enables dynamic policy updates without code changes and creates a data flywheel for improving the agent via the approval logs. This pattern is emerging from orchestration platforms like Inngest and Temporal applied to agent workflows in 2025.
