name: langgraph-multi-agent-router
version: 1.0.0
description: Orchestrate a multi-agent workflow where specialized agents collaborate
sequentially to gather information, structure it, and generate a final response
inputs:
- User query string (e.g., destination location)
- BedrockModel configuration (model_id, temperature, top_p)
- Pre-configured agents with specific system prompts and tool sets
steps:
- Researcher agent executes with system prompt to gather raw destination facts (places,
history, accommodations, food, web pages) using BedrockModel and available tools
(calculator, current_time)
- Travel guide agent receives raw research output and structures it into labeled sections
(Must-See Attractions, Historical Highlights, Accommodation Areas, Culinary Delights,
Suggested Web Pages)
- Writer agent receives the structured guide and synthesizes it into a professional
client-facing response with clear formatting and emphasis on the suggested web pages
outputs:
- Raw research data (JSON string containing gathered facts)
- Structured guide content (markdown-formatted travel guide with labeled sections)
- Final client response (professional formatted response ready for delivery)

# langgraph-multi-agent-router
Orchestrate a multi-agent workflow where specialized agents collaborate sequentially to gather information, structure it, and generate a final response
## Setup
**Dependencies:**
```text
pip install langchain langgraph bedrock-model pydantic
```
**Setup steps:**
1. Install langchain and langgraph packages
1. Configure BedrockModel with desired parameters (model_id, temperature, top_p)
1. Create three Agent instances with specific system prompts and tool sets
1. Initialize LangGraph with the agent chain and run the workflow
## Key Files
- `agents/langchain_langgraph/00-basic-agent/agent.py`
- `agents/langchain_langgraph/02-agent-with-tools-structured-output/agent.py`
- `agents/langchain_langgraph/08-langgraph-multi-agents-sequential-pattern/agent.py`
## Steps
1. Researcher agent executes with system prompt to gather raw destination facts (places, history, accommodations, food, web pages) using BedrockModel and available tools (calculator, current_time)
2. Travel guide agent receives raw research output and structures it into labeled sections (Must-See Attractions, Historical Highlights, Accommodation Areas, Culinary Delights, Suggested Web Pages)
3. Writer agent receives the structured guide and synthesizes it into a professional client-facing response with clear formatting and emphasis on the suggested web pages
## Implementation Details
```python
Researcher agent uses BedrockModel with temperature=0.7, top_p=0.9 to gather destination facts
```
```python
Travel guide agent receives raw output and formats into 5 labeled sections
```
```python
Writer agent takes structured guide and writes professional client response
```
## Inputs
- User query string (e.g., destination location)
- BedrockModel configuration (model_id, temperature, top_p)
- Pre-configured agents with specific system prompts and tool sets
## Outputs
- Raw research data (JSON string containing gathered facts)
- Structured guide content (markdown-formatted travel guide with labeled sections)
- Final client response (professional formatted response ready for delivery)
## Failure Modes
- Researcher agent fails to gather sufficient data or returns incomplete results
- Travel guide agent fails to structure information correctly or produces unreadable output
- Writer agent fails to format the final response properly or loses key information from the guide

This pattern can be adapted to other domains (e.g., code generation, data analysis, research workflows) by swapping the agent types and system prompts while maintaining the same three-step structure.",
