## Key Features

- **Agent Persona Registry**: Store and version each agent's system prompt, backstory, and tool schema in one governed registry. Per-agent isolation.
- **Swarm Hot-Patching**: Change a running agent's behavior in PromptMatrix. The next task cycle picks it up — no swarm restart, no downtime.
- **LangGraph Integration**: Pull node system prompts and tool schemas from PromptMatrix at each graph invocation via pm.serve().
- **CrewAI Integration**: Store agent backstories and system prompts in PromptMatrix. Hot-patch drifting crew members mid-task.
- **OpenClaw Integration**: PromptMatrix was built alongside OpenClaw for swarm persona governance and tool schema versioning.
- **Prompt Version Control**: Git-style versioning for every LLM prompt and agent persona. Full audit trail.
- **Approval Workflows**: Require engineer approval before any behavior change reaches the swarm.
- **LLM-as-Judge Evals**: Automated quality gates using LLM evaluation before merge.
- **Sub-5ms Serving**: Production-grade prompt API serving with AES-256-GCM encryption. L1/L2 cache hit <5ms, miss <30ms.
- **Zero-redeploy Updates**: Update agent personas live without touching your codebase or restarting your swarm.
