agentsync-vcs

Universal Agent VCS and package manager for AI Agent behaviors.

Overview

agentsync-vcs is not just a file mirror; it is a behavior compiler and distribution system for AI agents.

Unlike tools that merely copy text between IDEs, agentsync-vcs allows you to maintain a single, versioned source of truth in Git and compiles it into the optimized, native configuration for every AI tool in your stack (Cursor, Claude Code, Copilot, etc.). It enables engineering teams to enforce architectural standards and "harness engineering" guidelines across any environment.

Supported Targets

• Cursor: .cursor/rules/*.mdc and .cursorrules
• Claude Code: CLAUDE.md and .claude/skills/
• GitHub Copilot: .github/copilot-instructions.md and .github/instructions/*.md
• Windsurf: .windsurf/rules/*.md and .windsurfrules
• Trae: .trae/project_rules.md and .trae/skills/*.md
• Codex: AGENTS.md
• Gemini: GEMINI.md

Installation

Prerequisites

• Python 3.8+

Install via pip

pip install agentsync-vcs

Usage

Initialize a project

agentsync-vcs init

This creates a sample-rule.md file and a .agent-sync/ configuration folder.

Define a Rule

Create a .md file with YAML frontmatter:

---
name: my-rule
description: Guidelines for this project
globs: ["src/**/*.ts"]
type: rule # Optional: 'rule', 'skill', or 'global'
---
- Use functional programming patterns.
- Ensure all exports are documented.

Advanced Targets

• Cursor: Rules are compiled into modular .cursor/rules/*.mdc files. Use type: global for project-wide standards.
• Claude Code: Standard rules merge into CLAUDE.md. Use type: skill for modular capabilities in .claude/skills/.
• Windsurf: All rules are compiled into modular .windsurf/rules/*.md files for efficient context loading.
• Trae: Universal guidelines go to .trae/rules/project_rules.md. Use type: skill for modular .trae/skills/.
• GitHub Copilot: Uses .github/copilot-instructions.md for global rules and .github/instructions/*.md for path-specific ones.
• Gemini & Codex: All rules are intelligently merged into a single source of truth (GEMINI.md or AGENTS.md).

Remote Syncing

Sync rules from a shared team repository:

agentsync-vcs remote add https://github.com/my-org/agent-rules.git
agentsync-vcs sync
agentsync-vcs pull cursor

This will compile both your local rules and all rules from the remote Git repositories.
