## Overview

This is a reference ReAct agent service with a Streamlit monitoring interface. A user submits a task through the UI or API; the agent reasons with Grok, selects tools, applies guardrails and budget limits, records traces, and returns a final or partial result. Separate capabilities support run-history browsing, replay, and adversarial guardrail checks. The README documents the module layout and relationships, but the supplied file tree contains only README.md and no source excerpts, so repository-node paths are left null and the graph follows documented behavior only.
