📦 Installation

pip install swarmflow

🎯 Quick Start

from swarmflow import swarm_task, run

@swarm_task
def fetch_data():
    return "Some data from API"

@swarm_task
def process_data(fetch_data):
    return f"Processed: {fetch_data}"

@swarm_task
def display_result(process_data):
    print(f"Final result: {process_data}")

# Run workflow - that's it!
run()

That's it! No complex setup, no manual dependency management. SwarmFlow automatically:

• ✅ Registers your tasks
• ✅ Infers dependencies from function parameters
• ✅ Executes in the correct order
• ✅ Handles retries and errors
• ✅ Sends traces to your dashboard

🔧 Advanced Usage

Retry Logic

@swarm_task(retries=3)
def unreliable_task():
    # This task will retry up to 3 times on failure
    pass

Multiple Dependencies

@swarm_task
def step1():
    return "Step 1 completed"

@swarm_task
def step2():
    return "Step 2 completed"

@swarm_task
def step3():
    return "Step 3 completed"

@swarm_task
def final_step(step1, step2, step3):
    # Dependencies automatically inferred from parameter names
    return f"Combined: {step1}, {step2}, {step3}"

run()

Auto-Extracted Groq Metadata

from groq import Groq

@swarm_task
def llm_task():
    # This will automatically extract metadata from Groq responses
    client = Groq()
    response = client.chat.completions.create(
        model="llama-3-70b",
        messages=[{"role": "user", "content": "Hello"}]
    )
    return response

# SwarmFlow automatically detects and extracts:
# - Model name (llama-3-70b, llama-4-scout-17b, etc.)
# - Provider (Groq)
# - Token usage (prompt + completion tokens)
# - Precise cost calculation (USD)
# - Timing metrics (queue, prompt, completion, total time)
# - All added to task.metadata automatically

# Example output with metadata:
# [SwarmFlow] Task: llm_task
#   ↳ Status: success
#   ↳ Duration: 1234 ms
#   ↳ Output: <Groq ChatCompletion object>
#   ↳ Metadata: {'agent': 'LLMProcessor', 'provider': 'Groq', 'model': 'llama-3-70b', 'tokens_used': 150, 'cost_usd': 0.000089, 'queue_time_s': 0.1, 'prompt_time_s': 0.5, 'completion_time_s': 0.8, 'total_time_s': 1.4}

API Key Configuration

SwarmFlow automatically handles API keys with Martian-style simplicity:

# Option 1: Set environment variable
export SWARMFLOW_API_KEY="sk_abc123..."
run()  # Automatically uses key from environment

# Option 2: Pass directly
run(api_key="sk_abc123...")

# Option 3: No key (logs warning but continues)
run()  # Shows warning but executes normally

Hooks System & Shared Memory

SwarmFlow now includes a powerful hooks system for custom orchestration logic and shared memory for cross-task state management:

from swarmflow import swarm_task, run
from swarmflow.hooks import write_output_to_memory, read_memory_into_arg, log_input_output

@swarm_task(before=log_input_output()[0], after=log_input_output()[1])
def fetch_data():
    return "Some data from API"

@swarm_task(after=write_output_to_memory("processed_data"))
def process_data(fetch_data):
    return f"Processed: {fetch_data}"

@swarm_task(before=read_memory_into_arg("processed_data", "input_data"))
def display_result(process_data, input_data=None):
    print(f"Final result: {process_data}")
    print(f"From memory: {input_data}")

# Run workflow - that's it!
run()

Available Hooks:

• before: Execute before task runs
• after: Execute after task succeeds
• on_error: Execute when task fails
• on_final: Execute after task completes (success or failure)

Built-in Hook Utilities:

• write_output_to_memory(key): Save task output to shared memory
• read_memory_into_arg(mem_key, arg_name): Inject memory value into task arguments
• log_input_output(): Log task inputs and outputs
• enforce_max_cost(max_usd): Abort if total cost exceeds limit
• set_flag_on_failure(flag_key): Set memory flag when task fails
• skip_if_flag_set(flag_key): Skip task if memory flag is True

Policy Enforcement

Set DAG-level policies for cost limits, abort conditions, and validation:

from swarmflow import swarm_task, run, SwarmFlow

# Create flow for policy configuration
flow = SwarmFlow()
flow.set_policy("max_cost", 0.10)  # Abort if total cost > $0.10
flow.set_policy("abort_on_flag", "error_detected")  # Abort if flag is True
flow.set_policy("require_outputs", ["final_result"])  # Abort if missing outputs

@swarm_task
def task1():
    return "Task 1 result"

@swarm_task
def task2(task1):
    return "Task 2 result"

# Run with policies enforced
run()

Real-time Monitoring

SwarmFlow automatically sends task traces to the SwarmFlow backend service at http://localhost:8000/api/trace for real-time monitoring and analytics.

Trace Structure:

{
  "id": "task-uuid",
  "run_id": "dag-run-uuid",  // Consistent across all tasks in the same DAG run
  "name": "task_name",
  "status": "success|failure|retrying|skipped",
  "duration_ms": 1234,
  "output": "task output",
  "metadata": {
    "agent": "LLMProcessor",
    "provider": "Groq",
    "model": "llama-3-70b",
    "tokens_used": 150,
    "cost_usd": 0.000089
  },
  "dependencies": ["dep1", "dep2"],
  "flow_memory": {"key": "value"},  // Shared memory state
  "flow_policy": {"max_cost": 0.10}  // Active policies
}

Observability

SwarmFlow automatically provides:

• Task execution traces with OpenTelemetry
• Performance metrics (execution time, success rates)
• Dependency visualization and cycle detection
• Error tracking and failure propagation
• Auto-extracted Groq metadata (model, provider, token usage, precise cost calculation, timing metrics)

🏗️ Architecture

SwarmFlow is designed for production multi-agent systems with dead-simple usage:

User's Agent Functions → @swarm_task decorator → run() → Observability Dashboard

• Minimal: Just decorator + run function
• Scalable: Handles complex dependency graphs
• Observable: Real-time monitoring and debugging
• Resilient: Built-in retry logic and error handling

📊 Monitoring Dashboard

Get comprehensive insights into your multi-agent workflows:

• Real-time execution monitoring
• Performance analytics and optimization
• Error tracking and debugging
• Cost analysis for LLM usage (auto-calculated)
• Workflow visualization and dependency graphs
• Groq metadata extraction (comprehensive model support with timing and cost analytics)
• DAG run tracking with unique run_id for grouping and analytics

🚀 Deployment Configuration

API Key Authentication

SwarmFlow supports API key authentication for secure trace reporting:

# Option 1: Environment variable (recommended)
export SWARMFLOW_API_KEY="sk_abc123..."
run()  # Automatically picks up from environment

# Option 2: Pass directly
run(api_key="sk_abc123...")

# Option 3: No authentication (logs warning but continues)
run()  # Shows warning but executes normally

Backend Configuration

SwarmFlow automatically sends traces to http://localhost:8000/api/trace. For production deployment, update the backend URL in the SDK code to point to your centralized backend service.
