Report #68481

[architecture] Human-in-the-loop inserted too late or at every step, causing either catastrophic failure or workflow bottleneck

Gate HITL checkpoints strictly on action type \(e.g., write operations, external API calls, financial transactions\) rather than state transitions, using an 'allowlist' of autonomous actions.

Journey Context:
A common mistake is asking for human approval on every agent handoff, which destroys the ROI of automation. Conversely, fully autonomous agents will eventually cause damage. The solution is to categorize tools/actions into 'read/immutable' \(autonomous\) and 'write/mutable' \(requires HITL\). Tradeoff: limits the agent's ability to chain multiple write operations without human intervention, but guarantees safety boundaries.
