A Sequential Swarm architecture processes tasks in a linear sequence. Each agent completes its task before passing the result to the next agent in the chain. This architecture ensures orderly processing and is useful when tasks have dependencies. The system now includes **sequential awareness** features that allow agents to know about the agents ahead and behind them in the workflow, significantly enhancing coordination and context understanding.

A Sequential Swarm architecture processes tasks in a linear sequence. Each agent completes its task before passing the result to the next agent in the chain. This architecture ensures orderly processing and is useful when tasks have dependencies.
**Use-Cases:**
- Workflows where each step depends on the previous one, such as assembly lines or sequential data processing.
- Scenarios requiring strict order of operations.
- **NEW**: Enhanced workflows where agents need context about their position in the sequence for better coordination.
- Multi-step content creation, analysis, and refinement workflows.

## **Sequential Awareness Feature**
The SequentialWorkflow now includes a powerful **sequential awareness** feature that automatically provides each agent with context about their position in the workflow:
### What Agents Know Automatically
- **Agent ahead**: The agent that completed their task before them
- **Agent behind**: The agent that will receive their output next
- **Workflow position**: Their step number and role in the sequence
### Benefits
1. **Better Coordination**: Agents can reference previous work and prepare output for the next step
2. **Context Understanding**: Each agent knows their role in the larger workflow
3. **Improved Quality**: Output is tailored for the next agent in the sequence
4. **Enhanced Logging**: Better tracking of agent interactions and workflow progress
system_prompt="As a Litigator, you specialize in navigating the complexities of lawsuits. Your role involves analyzing intricate facts, constructing compelling arguments, and devising effective case strategies to achieve favorable outcomes for your clients.",
model_name="gpt-4o-mini",
max_loops=1,
)
### 1. **Automatic Context Injection**
When `team_awareness=True`, the system automatically adds awareness information to each agent's conversation context before they run:
# Corporate Attorney Agent
corporate_agent = Agent(
agent_name="Emily Carter",
system_prompt="As a Corporate Attorney, you provide expert legal advice on business law matters. You guide clients on corporate structure, governance, compliance, and transactions, ensuring their business operations align with legal requirements.",
model_name="gpt-4o-mini",
max_loops=1,
)
- **First Agent**: No awareness info (starts the workflow)
- **Middle Agents**: Receive info about both the agent ahead and behind
- **Last Agent**: Receives info about the agent ahead only
# IP Attorney Agent
ip_agent = Agent(
agent_name="Michael Smith",
system_prompt="As an IP Attorney, your expertise lies in protecting intellectual property rights. You handle various aspects of IP law, including patents, trademarks, copyrights, and trade secrets, helping clients safeguard their innovations.",
elevator_pitch = workflow.run("Generate and validate a startup idea in the AI space")
print(elevator_pitch)
```
### **Example 2: Code Review Workflow**
### Advanced: Materials Science Workflow
This example shows a complex workflow with multiple specialized materials science agents.
```python
# Create code review agents
linter = Agent(
agent_name="Code Linter",
system_prompt="Check code for syntax errors and style violations."
from swarms import Agent, SequentialWorkflow
# Chief Metallurgist
chief_metallurgist = Agent(
agent_name="Chief-Metallurgist",
system_prompt="As the Chief Metallurgist, you oversee the entire alloy development process, analyzing atomic structure, phase diagrams, and composition development.",
model_name="gpt-4o",
max_loops=1,
)
reviewer = Agent(
agent_name="Code Reviewer",
system_prompt="Review code quality and suggest improvements."
# Materials Scientist
materials_scientist = Agent(
agent_name="Materials-Scientist",
system_prompt="As the Materials Scientist, you analyze physical and mechanical properties including density, thermal properties, tensile strength, and microstructure.",
model_name="gpt-4o",
max_loops=1,
)
tester = Agent(
agent_name="Code Tester",
system_prompt="Write and run tests for the reviewed code."
# Process Engineer
process_engineer = Agent(
agent_name="Process-Engineer",
system_prompt="As the Process Engineer, you develop manufacturing processes including melting procedures, heat treatment protocols, and quality control methods.",
model_name="gpt-4o",
max_loops=1,
)
# Create workflow
workflow = SequentialWorkflow(
agents=[linter, reviewer, tester],
team_awareness=True
# Quality Assurance Specialist
qa_specialist = Agent(
agent_name="QA-Specialist",
system_prompt="As the QA Specialist, you establish quality standards, testing protocols, and documentation requirements.",
model_name="gpt-4o",
max_loops=1,
)
# Run code review process
result = workflow.run("Review and test the authentication module")
# Applications Engineer
applications_engineer = Agent(
agent_name="Applications-Engineer",
system_prompt="As the Applications Engineer, you analyze potential applications, performance requirements, and competitive positioning.",
model_name="gpt-4o",
max_loops=1,
)
# Cost Analyst
cost_analyst = Agent(
agent_name="Cost-Analyst",
system_prompt="As the Cost Analyst, you evaluate material costs, production costs, and economic viability.",
model_name="gpt-4o",
max_loops=1,
)
# Create the agent list
agents = [
chief_metallurgist,
materials_scientist,
process_engineer,
qa_specialist,
applications_engineer,
cost_analyst,
]
# Initialize the workflow
swarm = SequentialWorkflow(
name="alloy-development-system",
agents=agents,
)
# Run the workflow
result = swarm.run(
"""Analyze and develop a new high-strength aluminum alloy for aerospace applications
with improved fatigue resistance and corrosion resistance compared to 7075-T6,
while maintaining similar density and cost effectiveness."""
)
print(result)
```

## Best Practices
- **Enhanced Logging**: The workflow now logs sequential awareness information for better debugging and monitoring.
- **Automatic Context**: No manual configuration needed - awareness is automatically provided when `team_awareness=True`.
- **Backward Compatibility**: Existing workflows continue to work without changes.
Enable `team_awareness=True` to provide agents with context about their position in the workflow (this feature is managed by the internal `AgentRearrange` object):
```python
workflow = SequentialWorkflow(
agents=[researcher, writer, editor],
team_awareness=True,
)
```
### Multi-Agent Collaboration Prompt
Set `multi_agent_collab_prompt=True` to automatically append a collaboration prompt to each agent's system prompt:
```python
workflow = SequentialWorkflow(
agents=[agent1, agent2, agent3],
multi_agent_collab_prompt=True,
)
```
- **Enable Team Awareness**: Set `team_awareness=True` to unlock the full potential of sequential coordination.
- **Use Descriptive Agent Names**: Clear agent names make the awareness information more useful.
- **Monitor Logs**: Enhanced logging provides insights into how agents are coordinating.
- **Iterative Improvement**: Use the awareness features to refine agent prompts and improve workflow quality.
## Notes
## **Benefits of Sequential Awareness**
- The `SequentialWorkflow` internally uses `AgentRearrange` to manage agent execution.
- Each agent receives the output of the previous agent as its input.
- The workflow executes agents in the exact order they appear in the `agents` list.
- The workflow is designed for production use with comprehensive error handling and logging.
- For parallel execution, consider using `ConcurrentWorkflow` or `SpreadSheetSwarm` instead.
1. **Improved Quality**: Agents produce better output when they understand their context
2. **Better Coordination**: Reduced redundancy and improved handoffs between agents
3. **Enhanced Debugging**: Clear visibility into agent interactions and workflow progress
4. **Scalable Workflows**: Easy to add new agents while maintaining coordination
5. **Professional Workflows**: Mimics real-world team collaboration patterns
