The original title is: "Human-in-the-Loop for Solon ReActAgent: Pause Risky Tools Before They Run"

Short summary

This tutorial demonstrates how to implement Human-in-the-Loop (HITL) approval workflows on Solon AI's ReActAgent using the built-in HITLInterceptor, allowing risky tool calls like money transfers to be paused before execution. It covers two interception patterns — always-pause for sensitive tools and conditional pause based on argument thresholds — with full Java code examples for a web controller that manages approval, rejection, and argument modification. The approach keeps low-risk automation fast while fencing dangerous operations behind human review at the exact point between model decision and tool execution.

• •HITLInterceptor pauses risky ReActAgent tool calls before execution, not after
• •Two patterns: onSensitiveTool for always-pause, onTool with conditional strategy for threshold-based approval
• •Full Java web controller example shows approve/reject/modify-args workflow with session management
