Open-source AI coding agent (CLI)
Prime Agent
Prime Agent is Prime Intellect's MIT-licensed coding and research agent. Instead of a fixed set of tools, the model works through a persistent Python REPL: file edits, shell commands, and subagents are all code, and rlm.spawn() starts child agents for parallel or background work. Sessions persist through a local daemon, and the agent distills successful runs into a reusable skill library, which suits long, multi-hour tasks on one codebase.
