prime-agent: Run Self-Improving Agents for Coding Work

Overview

Prime Agent is a coding and research agent for general and long-running work. It uses a persistent Python environment to coordinate tools and recursive subagents, while a continual harness stores reusable context that can be refined over time.

This approach is useful when a task outlasts a single chat session or benefits from parallel work and retained progress. Unlike a simple code assistant, Prime Agent can keep sessions running in the background, resume them later, and preserve goals and operating patterns. It runs commands and modifies files in the working directory, so it is best used where changes can be inspected and rolled back.

Key Features

• Uses a persistent Python REPL as the control environment for tools, file operations, shell commands, and context management.
• Spawns child agents for parallel or background work and exposes their results programmatically.
• Refines supplemental prompts, memories, skill descriptions, and subagent specifications based on evidence from a session.
• Keeps sessions, REPL state, schedules, and subagents running after terminal detachment.
• Supports persistent goals, periodic heartbeats, scheduled work, and bounded autonomous runs.
• Provides agent-to-agent messaging and reusable skills implemented as importable Python packages.

Use Cases

• Developers can delegate multi-step coding or repository research tasks that need to continue while their terminal is disconnected.
• Research teams can run extended evaluations or investigations that benefit from retained context and recurring execution.
• Engineers can split independent parts of a task across subagents, then inspect their results within one workflow.
• Individuals with recurring project workflows can build reusable skills and refine supporting context from prior work.

Getting Started

Install the latest stable version:

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

Start it in the project directory with prime-agent. See the README for setup and usage details.

Alternatives

• openinterpreter: Open Interpreter focuses on low-cost models and integrations with agent harnesses, ACP editors, and Codex SDK clients rather than durable context for long-running tasks.
• ouroboros: Ouroboros emphasizes persistent identity and memory across restarts, while Prime Agent centers on a persistent Python environment and recursive subagents.
• grok-build: Grok Build offers a full-screen terminal UI and headless CI mode, while Prime Agent emphasizes persistent context and recursive subagents for long-running work.

Considerations

Prime Agent executes model-generated Python and project commands with the user's permissions. Its worker and kernel processes provide lifecycle isolation and recovery, but are not a security sandbox. Use trusted repositories and instructions, review changes, and run untrusted work in an external sandbox or restricted environment. The repository metadata reports NOASSERTION for the license, while the README states that the project is released under the MIT License, so verify the license file if licensing is important to your use.
