A human approves the risky step

What you will be able to do

Gate irreversible Helix actions behind a human approval before the write tool runs.

The idea

Reads can auto-run. Irreversible writes wait for a person.

The graph pauses on an approve node; the tool only runs after an explicit decision.

graph.add_edge("agent", "approve")
graph.add_edge("approve", "write_tool")  # only if human said yes

If it cannot be undone, a human must say yes.

Key takeaways

• Classify tools: read vs irreversible.
• Approve node before writes.
• Logs keep the decision.
