AgentDiff Coordination

AgentDiff is a lightweight coordination library that prevents common concurrency issues in multi-agent systems - such as agents starting before dependencies complete, multiple agents writing to shared resources, or concurrent API calls exceeding rate limits.

Simply add @coordinate decorators for resource locks and @when for event-driven chaining. AgentDiff integrates with existing agent frameworks like LangChain, CrewAI, or pure Python implementations.

Provides coordination primitives without requiring framework migration or architectural changes.

What AgentDiff Coordination Solves

• Race conditions between agents accessing shared resources.
• Corrupted state when multiple agents write to the same keys.
• API rate limit chaos from concurrent LLM calls.
• "Two nodes writing to same key" bugs that require extensive debugging.
• Framework complexity that gets in the way of actually building agents.

Core Features

• @coordinate - Resource locks + automatic lifecycle events.
• @when - Event-driven agent chaining (no manual orchestration).
• emit() - Custom events for complex workflows.
• Zero Configuration - Works immediately, configure only what you need.
• Framework Agnostic - Works with any agent framework or pure Python.

Use Cases: Concurrency Issues and Race Conditions

Concurrent State Updates

# Before: Race conditions in shared state
def process_customer_data():
    customer_state["status"] = "processing"  # Race condition
    result = process_data()
    customer_state["result"] = result       # Overwrites other agent

def update_customer_profile():
    customer_state["status"] = "updating"   # Conflicts with processor
    customer_state["profile"] = new_profile # State corruption

# After: Resource locks prevent conflicts
@coordinate("data_processor", lock_name="customer_123")
def process_customer_data():
    customer_state["status"] = "processing"  # Exclusive access
    result = process_data()
    customer_state["result"] = result        # Safe update

@coordinate("profile_updater", lock_name="customer_123")
def update_customer_profile():
    customer_state["status"] = "updating"    # Waits for processor
    customer_state["profile"] = new_profile  # No conflicts

API Rate Limit Management

# Before: Multiple agents hitting APIs simultaneously
def research_agent():
    response = openai.chat.completions.create(...)  #  Rate limited

def analysis_agent():
    response = openai.chat.completions.create(...)  #  Rate limited

def summary_agent():
    response = openai.chat.completions.create(...)  #  Rate limited

# Running in parallel creates debugging challenges
threading.Thread(target=research_agent).start()
threading.Thread(target=analysis_agent).start()
threading.Thread(target=summary_agent).start()

# After: Resource locks queue API calls safely
@coordinate("researcher", lock_name="openai_api")
def research_agent():
    response = openai.chat.completions.create(...)  #  Queued safely

@coordinate("analyzer", lock_name="openai_api")
def analysis_agent():
    response = openai.chat.completions.create(...)  #  Waits for researcher

@coordinate("summarizer", lock_name="openai_api")
def summary_agent():
    response = openai.chat.completions.create(...)  #  Waits for analyzer

Manual Orchestration Complexity

# Before: Complex manual coordination
def run_workflow():
    research_result = research_agent()
    if research_result:
        analysis_result = analysis_agent(research_result)
        if analysis_result:
            summary_result = summary_agent(analysis_result)
            if summary_result:
                final_report = editor_agent(summary_result)
    # Error handling, retries, parallel flows increase complexity

# After: Event-driven coordination
@coordinate("researcher")
def research_agent():
    return research_data

@when("researcher_complete")
def start_analysis(event_data):
    analysis_agent(event_data['result'])  #  Auto-triggered

@when("analyzer_complete")
def start_summary(event_data):
    summary_agent(event_data['result'])   #  Auto-chained

# Just start the workflow - coordination happens automatically
research_agent()  # Everything else flows automatically
