-version: 1.0.0
-description: Orchestrate a sequence of specialized agents to perform multi-step tasks
-  like research, data processing, and final output generation
-inputs:
-- BedrockModel with temperature=0.3, top_p=0.8
-- Researcher agent with system prompt for destination research (places, history, accommodations,
-  food, web pages)
-- Travel Guide Generator agent with system prompt for structuring travel guides into
-  labeled sections
-- Writer agent with system prompt for formatting professional client responses
-steps:
-- Researcher agent gathers raw destination facts (top 5 attractions, historical facts,
-  best areas, local foods, suggested web pages) using BedrockModel
-- Travel Guide Generator agent structures the raw facts into a comprehensive travel
-  guide with clearly labeled sections
-- Writer agent formats the structured guide into a professional client-facing response
-  with the full guide and highlighted web pages
-outputs:
-- Raw research data (JSON string containing destination facts and categories)
-- Structured travel guide content (markdown with sections for attractions, history,
-  accommodations, cuisine, and web pages)
-- Final client response (formatted travel guide ready for delivery)

-# langgraph-multi-agent-sequential
-
-Orchestrate a sequence of specialized agents to perform multi-step tasks like research, data processing, and final output generation
-
-## Setup
-
-**Dependencies:**
-
-```text
-pip install langchain langgraph bedrock-model pydantic
-```
-
-**Setup steps:**
-
-1. Install langchain and langgraph packages
-1. Configure BedrockModel with temperature=0.3 and top_p=0.8
-1. Create three Agent instances with appropriate system prompts and tools
-1. Deploy the FastAPI server with the LangGraph application
-
-## Key Files
-
-- `agents/langchain_langgraph/08-langgraph-multi-agents-sequential-pattern/agent.py`
-- `agents/langchain_langgraph/08-langgraph-multi-agents-sequential-pattern/app.py`
-
-## Steps
-
-1. Researcher agent gathers raw destination facts (top 5 attractions, historical facts, best areas, local foods, suggested web pages) using BedrockModel
-2. Travel Guide Generator agent structures the raw facts into a comprehensive travel guide with clearly labeled sections
-3. Writer agent formats the structured guide into a professional client-facing response with the full guide and highlighted web pages
-
-## Implementation Details
-
-```python
-Researcher agent with system_prompt for destination research and tools=[calculator, current_time]
-```
-
-```python
-Travel Guide Generator agent with system_prompt requiring structured sections (attractions, history, accommodations, cuisine, web pages)
-```
-
-```python
-Writer agent with system_prompt for client-facing response formatting
-```
-
-## Inputs
-
-- BedrockModel with temperature=0.3, top_p=0.8
-- Researcher agent with system prompt for destination research (places, history, accommodations, food, web pages)
-- Travel Guide Generator agent with system prompt for structuring travel guides into labeled sections
-- Writer agent with system prompt for formatting professional client responses
-
-## Outputs
-
-- Raw research data (JSON string containing destination facts and categories)
-- Structured travel guide content (markdown with sections for attractions, history, accommodations, cuisine, and web pages)
-- Final client response (formatted travel guide ready for delivery)
-
-## Failure Modes
-
-- Researcher agent fails to retrieve sufficient information, causing downstream agents to receive incomplete or empty data
-- Travel Guide Generator fails to structure data properly, resulting in unorganized or malformed output
-- Writer agent fails to format the final response correctly, producing garbled or incomplete output
-- Model timeouts or errors in any agent step causing the entire pipeline to fail
