stigmergy-crewai 0.1.2

Stigmergy pressure-field scheduling adapter for CrewAI

stigmergy-crewai

Optimal task ordering for CrewAI crews. Declare tasks with priorities and dependencies, and stigmergy computes the best execution order using pressure signals. No manual ordering required.

5 lines to integrate. Works with your existing CrewAI agents.

Install

pip install stigmergy-crewai

Usage

from crewai import Agent
from stigmergy_crewai import StigmergyManager

# Create CrewAI agents
researcher = Agent(role="researcher", goal="Find information", llm=llm)
writer = Agent(role="writer", goal="Write content", llm=llm)
editor = Agent(role="editor", goal="Edit content", llm=llm)

# Create stigmergy manager with tasks and dependencies
manager = StigmergyManager(wake_threshold=0.4)
manager.add_task("research", agent=researcher, description="Research AI trends",
                 expected_output="Key findings", priority=0.8)
manager.add_task("write", agent=writer, description="Write article",
                 expected_output="Draft article", priority=0.6, deps=["research"])
manager.add_task("edit", agent=editor, description="Edit the draft",
                 expected_output="Final article", priority=0.5, deps=["write"])

# Preview execution order
print(manager.task_order)  # ['research', 'write', 'edit']

# Build and run
crew = manager.build_crew(verbose=True)
result = crew.kickoff()

How It Works

Since CrewAI's Process enum is not extensible, the StigmergyManager:

1. Accepts tasks with priorities and dependency graphs
2. Uses pressure signals to resolve optimal execution order
3. Deposits completion signals that propagate to dependent tasks
4. Builds a CrewAI Crew with tasks in the resolved order
5. Uses CrewAI's context parameter to pass outputs between dependent tasks

Limitations

• Cannot parallelize tasks (CrewAI sequential process limitation)
• Cannot dynamically inject tasks mid-execution
• Task ordering is resolved at build_crew() time, not runtime

For full dynamic scheduling, use the core stigmergy library directly.
