Prime Agent

Prime Agent is an open-source command-line coding and research agent for general and long-running tasks, developed by Prime Intellect. It combines recursive language-model workflows through an RLM harness with a persistent Python REPL, treating prompts as variables and invoking tools and recursive subagents programmatically. A continual harness stores supplemental prompts, memories, skill descriptions, and reusable subagent specifications as durable session state that can be refined through small, evidence-backed updates without changing the immutable base system prompt. The agent supports importable Python skills, parallel or background child agents, messaging between running agents, automatic context compaction, persistent goals, heartbeats, schedules, detached sessions, autonomous operation, and retained subagents.

What Prime Agent is used for

3 uses taken from transcripts — each links to the moment in the video.

  • An open-source command-line coding and research agent for general and long-running tasks. It uses persistent Python sessions, child agents, reusable memories and skills, and background execution.

  • An open-source coding agent designed for long-running work. It uses recursive language-model processes, durable prompts, memories, and skills, with parallel sub-agents, persistent sessions, schedules, goals, and bounded autonomous operation.

  • A self-improving coding agent for long-running tasks that uses recursive language-model workflows, durable prompts, memories and skills, parallel subagents, detached sessions, goals, schedules, and bounded autonomous mode.
