Human-in-the-Loop (HITL) Pattern
What It Is
Human-in-the-loop (HITL) requires explicit human approval for specific actions or decisions.
It is not a “fallback to a human” when the model is confused. It is a deliberate control point for high-stakes operations.
Good HITL design includes clear proposals, evidence, risk flags, and a simple approve/deny/escalate flow.
Why It Matters in Enterprise
Many business actions have legal, financial, or reputational impact; accountability must remain human.
HITL reduces risk while still capturing productivity gains: the agent prepares, the human approves.
It also supports governance: approvals become auditable records and enable process compliance.
Common Mistakes
- Using HITL as a crutch because the agent is unreliable, instead of fixing grounding/tools/guardrails.
- Asking humans to review raw model text instead of structured proposals and evidence.
- No routing: approvals go to the wrong people, causing delays and bypasses.
- Not designing deny/undo paths, making “approve” the only workable option.
How Copyl Supports This Pattern
- Copyl supports enterprise workflows where actions can be gated by explicit approvals.
- Audit logs and identity ensure approvals are attributable and reviewable.
- This enables safe automation: agents propose, humans decide, systems execute.
