This commit introduces a multi-agent Swarm Engine to PicoClaw,
enabling complex task orchestration through autonomous collaboration and long-term
semantic memory.
Key Features:
- Actor Model Architecture: Every agent (node) runs in an isolated goroutine,
communicating via a lightweight internal Event Bus.
- Hierarchical Delegation: Manager nodes can dynamically spawn specialized
worker nodes (Researchers, Analysts, etc.) to perform sub-tasks in parallel.
- Hybrid Memory System: Combined SQLite for state persistence and Chromem-go
for a persistent, cross-swarm Vector Knowledge Base.
- Progressive Summarization: Implemented an intelligent memory pruning mechanism
that summarizes older context before truncation to preserve findings without
exceeding token limits.
- Role-Based Access Control (RBAC): Configurable tool policies per role
(e.g., Researchers can browse but not execute shell commands).
Performance & Scaling:
- Low Footprint: Idle memory usage is ~7-8 MB RSS.
- Efficient Scaling: During a stress test with 10 concurrent agents performing
intensive research, memory usage peaked at only 27 MB.
- Per-Node Cost: Each active agent consumes approximately 0.6 MB to 2 MB of
physical RAM depending on conversation length and summarization state.
- Stability: Successfully handled 10 parallel LLM requests with zero race
conditions, showcasing the robustness of the Go-based Actor model.
Integration:
- Native CLI Support: Added /swarm spawn, /swarm list, and /swarm status commands.
- Mermaid Visualization: Support for /swarm viz <id> to generate organizational
charts of active agent hierarchies.
- Configurable: Roles, models, and security policies are fully customizable
via config.json.
