+# langgraph-agent-workflow
+
+Orchestrate multi-step AI agents using LangGraph with SerperDevTool for RAG, code execution, and citation generation
+
+## Setup
+
+**Dependencies:**
+
+```text
+pip install langgraph>=0.7.0 serper-dev-tool>=0.1.0 qdrant-client or opensearch-dsl neo4j-driver or arango-database-driver react, next.js
+```
+
+**Setup steps:**
+
+1. Install LangGraph and SerperDevTool dependencies
+1. Configure vector store (Qdrant/OpenSearch) and knowledge graph (Neo4j/ArangoDB)
+1. Define chain topology with retrieval, reasoning, and response steps
+1. Build React agent frontend using create_react_agent
+1. Test multi-step agent workflows end-to-end
+
+## Key Files
+
+- `pipeshub-ai/workflows/agent_chain.py - Main LangGraph chain definition`
+- `pipeshub-ai/workflows/agent_react.py - React agent wrapper`
+- `pipeshub-ai/workflows/rag_pipeline.py - RAG with citation generation`
+- `pipeshub-ai/workflows/code_sandbox.py - Code execution sandbox`
+
+## Steps
+
+1. Step 1: Define LangGraph chain architecture with SerperDevTool integration - Create a LangGraph chain that combines retrieval, reasoning, and response generation using SerperDevTool for tool access
+2. Step 2: Implement React agent wrapper - Use create_react_agent to build a frontend agent that can interact with the LangGraph chain
+3. Step 3: Configure RAG pipeline - Set up vector search (Qdrant/OpenSearch) and knowledge graph retrieval (Neo4j/ArangoDB) with citation generation
+4. Step 4: Add code execution sandbox - Integrate artifact generation capabilities for code-related tasks
+5. Step 5: Orchestrate multi-step research workflow - Chain search → deep research → agent response in a single LangGraph workflow
+
+## Implementation Details
+
+```python
+chain = LangGraph()
+```
+
+```python
+chain.add_step(SerperDevToolAgent())
+```
+
+```python
+agent = create_react_agent(chain, SerperDevToolAgent())
+```
+
+```python
+workflow = chain.start()
+```
+
+## Inputs
+
+- LangGraph chain configuration files defining agent workflows
+- SerperDevTool integration for LLM tool access
+- React agent creation scripts via create_react_agent
+- Knowledge graph retrieval and citation generation pipelines
+
+## Outputs
+
+- Reusable LangGraph chain definition (pyfile) with configurable steps
+- React agent frontend component that can be deployed independently
+- RAG pipeline that generates block citations and grounded answers
+- Code execution sandbox for artifact generation
+- Documentation for parameterizing workflows for different tasks
+
+## Failure Modes
+
+- GraphDB connection failures if Neo4j/ArangoDB is not properly configured
+- Vector store unavailability (Qdrant/OpenSearch) causing RAG pipeline to fail
+- LLM tool access errors if SerperDevTool is not properly initialized
+- Agent timeout if complex multi-step reasoning exceeds time limits
+- Sandbox execution failures if code has security vulnerabilities or infinite loops
