-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()
-```

-- 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
