GBrain — Opinionated AI Agent Configuration Framework

Introduction

GBrain is an opinionated configuration framework for AI coding agents. It packages curated tools, prompts, and workflow configurations into a ready-to-use setup for OpenClaw, Hermes Agent, and other compatible agent runtimes.

What GBrain Does

• Provides a curated set of agent tools covering common development workflows
• Configures agent roles like CEO, Designer, Engineer, and QA perspectives
• Sets up structured workflow pipelines for code review, design, and deployment
• Includes pre-tuned system prompts optimized for developer productivity
• Offers a one-command setup that configures the entire agent environment

Architecture Overview

GBrain is a configuration layer, not a runtime. It generates and manages configuration files, system prompts, and tool definitions that agent runtimes consume. The framework uses a modular structure where each tool or role is defined independently and composed into workflow pipelines through a central config.

Self-Hosting & Configuration

• Clone the repository and run the init command to scaffold configurations
• Select which agent runtime to target (OpenClaw, Hermes Agent, etc.)
• Customize role definitions and workflow pipelines in the config directory
• Add or remove tools from the curated set based on your needs
• Export configurations for team sharing and version control

Key Features

• Opinionated defaults that work out of the box for common dev workflows
• Multi-role agent perspectives (engineering, design, QA, management)
• Modular tool system with easy add/remove customization
• Workflow pipelines for structured multi-step processes
• Compatible with multiple agent runtimes

Comparison with Similar Tools

• GStack — broader toolkit from the same author; GBrain focuses on agent brain config
• Oh-My-OpenAgent — orchestration layer; GBrain is configuration, not orchestration
• CLAUDE.md — single-file project config; GBrain is a multi-file framework with roles
• Archon — harness builder; GBrain provides pre-built configurations rather than building tools

FAQ

Q: Do I need a specific agent runtime? A: GBrain supports OpenClaw and Hermes Agent. Check the docs for the latest compatibility list.

Q: Can I modify the included tools? A: Yes. Each tool is defined in its own config file and can be customized or replaced.

Q: Is this useful for solo developers? A: Yes. The multi-role approach helps solo developers consider different perspectives (design, QA) during development.

Q: How do I share configs with my team? A: The config directory is designed to be committed to your project repository for team-wide consistency.
