glooit 🧴

Sync AI coding assistant configurations across Claude Code, Cursor, Codex, OpenCode, and Roo Code/Cline.

• Rules - Agent instructions and guidelines
• Commands - Custom slash commands
• Skills - Reusable agent capabilities
• Agents - Custom agent definitions
• MCP Servers - Model Context Protocol configurations
• Agent Hooks - Lifecycle hooks for Claude Code and Cursor

Why glooit?

Teams today use different AI coding assistants - some prefer Claude Code, others use Cursor, OpenCode, and CI/CD might run on Codex. Each tool has its own config format and location:

• Claude Code reads CLAUDE.md, commands in .claude/commands/, skills in .claude/skills/
• Cursor uses .cursor/rules/*.mdc with frontmatter, commands in .cursor/commands/
• OpenCode expects AGENTS.md, commands in .opencode/command/, agents in .opencode/agent/
• Codex expects AGENTS.md
• Roo Code/Cline looks in .roo/rules/

glooit lets you write your rules once and sync them everywhere. Perfect for:

• Multi-agent teams - Everyone uses their preferred AI assistant with consistent rules
• Monorepos - Different rules for different packages, all managed centrally
• CI/CD pipelines - Same rules in development and automation
• Evolving tooling - Switch or add AI assistants without rewriting configs

Install

# Homebrew (macOS/Linux)
brew tap nikuscs/glooit https://github.com/nikuscs/glooit
brew install glooit

# npm
npm install -g glooit

# bun
bun install -g glooit

# pnpm
pnpm install -g glooit

Quick Start

glooit init              # Create config
glooit sync              # Sync rules to all agents

Configuration

Create .glooit/main.md with your rules, then configure glooit.config.ts:

import { defineRules } from 'glooit';

export default defineRules({
  rules: [
    {
      file: '.glooit/main.md',
      to: './',
      targets: ['claude', 'cursor', 'codex']
    }
  ]
});

Run glooit sync (or bunx glooit sync / npx glooit sync) and it creates:

• CLAUDE.md for Claude Code
• .cursor/rules/main.mdc for Cursor
• AGENTS.md for Codex

Supported Agents

| Agent | Output Path | Format | |-------|-------------|--------| | claude | CLAUDE.md | Markdown | | cursor | .cursor/rules/{name}.mdc | Frontmatter | | codex | AGENTS.md | Markdown | | opencode | AGENTS.md | Markdown | | roocode | .roo/rules/{name}.md | Markdown | | generic | {name}.md | Markdown |

Feature Support Matrix

| Feature | Claude | Cursor | OpenCode | Codex | Roo Code/Cline | Generic | |-------------|--------|--------|----------|-------|----------------|---------| | Rules | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | Commands | ✓ | ✓ | ✓ | - | - | - | | Skills | ✓ | ✓ | ✓* | - | - | - | | Agents | ✓ | ✓ | ✓ | - | - | - | | MCP Servers | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | Hooks | ✓ | ✓ | - | - | - | - |

*OpenCode uses Claude-compatible skills path (.claude/skills/)

Features

Custom Paths

Override output locations per-agent:

{
  file: '.glooit/backend.md',
  to: './',
  targets: [
    'claude',
    { name: 'cursor', to: './backend/.cursor/rules/api.mdc' }
  ]
}

Directory Sync

Sync commands, skills, and agents directories at the top level:

export default defineRules({
  rules: [...],

  // Simple string path (defaults to claude, cursor, opencode)
  commands: '.glooit/commands',

  // Or with explicit targets
  skills: {
    path: '.glooit/skills',
    targets: ['claude']
  },

  agents: {
    path: '.glooit/agents',
    targets: ['claude', 'cursor']
  }
});

Output mappings:

• commands → .claude/commands, .cursor/commands, .opencode/command
• skills → .claude/skills, .cursor/skills (OpenCode uses .claude/skills)
• agents → .claude/agents, .cursor/agents, .opencode/agent

File Merging

Combine multiple files into one output:

{
  file: [
    '.glooit/coding-standards.md',
    '.glooit/testing-guidelines.md'
  ],
  to: './',
  targets: [
    { name: 'claude', to: './GUIDELINES.md' }
  ]
}

Globs (Cursor)

Limit rule scope to specific files:

{
  file: '.glooit/frontend.md',
  to: './apps/frontend',
  globs: 'src/**/*.{ts,tsx}',
  targets: ['cursor']
}

Transforms

Transform content during sync using placeholders in your source files.

Source file (.glooit/main.md):

# Project Guidelines

Last updated: __TIMESTAMP__

## Project Structure

__STRUCTURE__

## Environment

- Node version: __NODE_VERSION__
- API URL: __API_URL__

Config (glooit.config.ts):

import { defineRules, transforms } from 'glooit';

export default defineRules({
  rules: [
    {
      file: '.glooit/main.md',
      to: './',
      targets: ['claude'],
      hooks: ['replaceStructure', 'addTimestamp', 'replaceEnv']
    }
  ],
  transforms: {
    after: [transforms.compact({ removeFillerWords: true })]
  }
});

Built-in transforms:

| Transform | Placeholder | Description | |-----------|-------------|-------------| | addTimestamp | __TIMESTAMP__ | Replaced with current date/time | | replaceEnv | __ENV_VAR__ | Replaced with process.env.ENV_VAR value | | replaceStructure | __STRUCTURE__ | Replaced with project directory tree | | compact | - | Cleans up markdown (removes filler words, extra newlines) |

Usage:

• Per-rule transforms: Add hooks: ['transformName'] to individual rules
• Global transforms: Add to transforms.after array to run on all rules

Agent Hooks

Configure lifecycle hooks that run inside Claude Code and Cursor when the AI uses tools.

export default defineRules({
  rules: [...],
  hooks: [
    // Run prettier after file edits
    {
      event: 'afterFileEdit',
      command: 'npx prettier --write',
      targets: ['claude', 'cursor']
    },

    // Run a TypeScript script before shell commands
    {
      event: 'beforeShellExecution',
      script: '.glooit/hooks/check-command.ts',
      targets: ['claude']
    },

    // Block writes to sensitive files
    {
      event: 'PreToolUse',
      script: '.glooit/hooks/block-env-writes.ts',
      matcher: 'Edit|Write',  // Claude Code matcher
      targets: ['claude']
    }
  ]
});

Supported events:

| Event | Claude Code | Cursor | Description | |-------|-------------|--------|-------------| | PreToolUse | ✓ | - | Before tool execution (can block) | | PostToolUse | ✓ | - | After tool completion | | beforeShellExecution | ✓ | ✓ | Before shell commands | | afterFileEdit | ✓ | ✓ | After file modifications | | Stop | ✓ | ✓ | When agent finishes |

Script types:

• .ts files: Run with bun run
• .js files: Run with node
• .sh files: Run directly

MCP Configuration

Configure Model Context Protocol servers:

export default defineRules({
  rules: [...],
  mcps: [
    {
      name: 'postgres',
      config: {
        command: 'uvx',
        args: ['mcp-server-postgres'],
        env: { DATABASE_URL: process.env.DATABASE_URL }
      },
      targets: ['claude', 'cursor']
    }
  ]
});

Backup

Automatic backups before sync:

export default defineRules({
  rules: [...],
  backup: {
    enabled: true,
    retention: 10
  }
});

Commands

glooit init              # Initialize configuration
glooit sync              # Sync rules and MCPs
glooit validate          # Validate configuration
glooit clean             # Clean .gitignore entries
glooit reset --force     # Remove all generated files
glooit upgrade           # Upgrade glooit to latest version
glooit backup list       # List available backups
glooit backup restore <timestamp>  # Restore from backup

Upgrade

The upgrade command auto-detects your package manager and whether glooit is installed locally or globally:

glooit upgrade           # Auto-detect and upgrade
glooit upgrade -g        # Force global upgrade
glooit upgrade -l        # Force local upgrade

All commands work with npx, bunx, or pnpx:

npx glooit sync
bunx glooit sync
pnpx glooit sync

Examples

See examples/full.config.ts for a complete configuration with all features.
