Prime Agent

Prime Agent is an open-source, self-improving coding harness that utilizes Recursive Language Model (RLM) and Continual Harness abstractions to manage complex, long-horizon tasks. It enables agents to programmatically manage their own state, sub-agents, and memory through a persistent IPython kernel, allowing for autonomous, iterative improvement.

It enables agents to programmatically manage their own state, sub-agents, and memory through a persistent IPython kernel, allowing for autonomous, iterative improvement.

key features
  • 01Recursive Language Model (RLM) architecture for programmatic sub-agent delegation
  • 02Continual Harness for online, reset-free self-improvement of prompts, skills, and memory
  • 03Persistent IPython kernel integration for stateful, long-horizon task management
  • 04Autonomous mode with goal-setting, heartbeats, and gate-based verification
  • 05Agent-to-Agent (A2A) messaging for complex orchestration across sub-agent swarms
