+# agent-builder-workflow
+
+Build no-code AI agents that connect to enterprise knowledge sources, perform unified search and deep research, and generate explainable answers with citations
+
+## Setup
+
+**Dependencies:**
+
+```text
+pip install langchain langgraph serper-dev-tool qdrant-client redis fastapi pydantic
+```
+
+**Setup steps:**
+
+1. Install dependencies: pip install langchain langgraph serper-dev-tool qdrant-client redis fastapi
+1. Configure knowledge sources in .env (graph DB connection, vector DB, document paths)
+1. Define agent task in agent_builder.py with objectives and retrieval strategy
+1. Run agent chain: python agent_chain.py --task "research_quantum_computing"
+1. For code execution: add sandbox step to agent_chain.py with code generation and safe execution
+
+## Key Files
+
+- `pipeshub-ai/backend/agent_chain.py - LangGraph chain definition for agent workflows`
+- `pipeshub-ai/backend/retrieval_pipeline.py - Knowledge graph and vector search implementation`
+- `pipeshub-ai/workflows/agent_builder.py - No-code agent creation interface`
+- `pipeshub-ai/workflows/citation_generator.py - Block citation generation from retrieved sources`
+
+## Steps
+
+1. Step 1: Define agent task and objectives - Specify what the agent should do (e.g., answer a question, perform deep research on a topic, generate a report with citations)
+2. Step 2: Configure knowledge sources - Connect to enterprise documents, databases, or external systems that will serve as the agent's context
+3. Step 3: Build LangGraph chain - Create a workflow chain using LangGraph that combines retrieval (graph/vector) and LLM response generation with citation capabilities
+4. Step 4: Execute agent - Run the LangGraph chain to process the task and generate responses with grounded citations
+5. Step 5: (Optional) Code execution sandbox - If the agent needs to generate or execute code, deploy it to a safe sandbox environment for verification
+
+## Implementation Details
+
+```python
+LangGraph chain with retrieval (graph/vector) and LLM response stages
+```
+
+```python
+Knowledge graph construction from enterprise documents
+```
+
+```python
+Citation formatting using block references to source documents
+```
+
+## Inputs
+
+- Task description and agent objectives (e.g., answer Q&A, research specific topics, generate reports)
+- Knowledge sources (documents, databases, enterprise systems) to connect to
+- Retrieval strategy configuration (graph-based knowledge graph vs. vector search)
+- Output requirements (citation format, response structure, code execution needs)
+
+## Outputs
+
+- Agent execution logs showing retrieval steps and LLM responses
+- Grounded answers with block citations to source documents
+- Generated reports or artifacts (if code execution was performed)
+- Structured task completion status and results
+
+## Failure Modes
+
+- Insufficient retrieval results due to poor knowledge graph connectivity or vector embedding quality
+- Permission errors when accessing enterprise knowledge sources
+- LLM context window overflow when generating long explanations with citations
+- Sandbox execution failures for code generation or execution tasks
+- Timeout errors during multi-step agent chain execution
