-**A control plane that makes agentic systems shippable: tracing + eval gates + fallback + budgets + replay.**

-TraceFlow Lite wraps your LLM calls with enterprise-ready reliability mechanisms: eval gates, cost/latency constraints, provider abstraction, trace persistence, and replay capabilities — all orchestrated through LangGraph.
+**An Agent Reliability & Evaluation Control Plane SDK.**  
+Tracing + replay (SQLite), eval gates (PASS/REVISE/FALLBACK), provider routing/fallback, and cost/latency budgets — so agentic systems are **safe to ship and easy to operate**.
+
+> **Portfolio summary:** Built an agent reliability control plane SDK with eval gates (PASS/REVISE/FALLBACK), trace + replay (SQLite), provider routing/fallback, and cost/latency budgets — implemented as an internal LangGraph-orchestrated pipeline.
+
+**Proof:** Live Streamlit demo + video walkthrough + persisted traces you can replay.
+
+TraceFlow Lite sits between your app and LLM providers, enforcing **change safety** (quality gates + revise loops) and **operability** (traces, replay, budgets, retries).  
+*Internally, TraceFlow orchestrates a multi-node workflow using LangGraph.*

-## Quick Start
+## Quickstart
+
+Get up and running in 60 seconds:
+
+```bash
+# 1. Clone and install
+git clone https://github.com/khalilCodeX/traceflow-lite.git
+cd traceflow-lite
+poetry install
+
+# 2. Set your API key
+export OPENAI_API_KEY="sk-..."
+
+# 3. Launch the UI
+make ui
+```
+
+Open http://localhost:8501 — select a model, type a query, and hit **Execute**. That's it!
+
+Or try it programmatically:
+
+```bash
+poetry run python -c "
+from client import TraceFlowClient
+result = TraceFlowClient().run('What is machine learning?')
+print(result.answer)
+"
+```
+
