Report #61973

[architecture] Placing human-in-the-loop only at the end of a multi-agent pipeline allows irreversible errors to compound

Insert human-in-the-loop checkpoints immediately before any agent action that is hard or impossible to reverse \(e.g., executing a transaction, sending an email, deleting records\).

Journey Context:
Reviewing the final output of a 5-agent pipeline is useless if Agent 2 already sent the email. People treat HITL as a final QA step, but in agentic workflows, execution is distributed. Tradeoff: interrupting the flow reduces autonomy and increases latency, but prevents catastrophic autonomous failures.
