Prime Agent is an open-source coding and research agent for general and long-running work. It is designed around two core abstractions:

- The **[Recursive Language Model (RLM)](https://www.primeintellect.ai/blog/rlm)** treats context as variables (*prompt-as-a-variable*) and tools like recursive subagents as function calls (*programmatic tool /sub-agent calling*) inside a persistent REPL.
- The **[Continual Harness](https://arxiv.org/abs/2605.09998)** stores supplemental prompts, memories, skill descriptions, and reusable subagent specifications as durable state that Prime Agent can refine through small, evidence-backed updates, local to the session by default.

## Install

Install the latest stable version with the one-command installer:

```bash
curl -fsSL https://app.primeintellect.ai/prime-agent/install.sh | sh
```

On Windows, install from PowerShell:

```powershell
irm https://app.primeintellect.ai/prime-agent/install.ps1 | iex
```

The Windows installer downloads the latest stable Windows x64 build and verifies its checksum before installation.

## Why Prime Agent

Prime Agent combines a persistent Python control environment with durable harness state, so useful working context and reusable operating patterns can outlive a single chat window.

- **Everything is programmatic:** a persistent Python REPL is the built-in model tool; file operations, shell commands, tool use, subagents, and context management
