ContextMark

Your Claude Code Context, Versioned and Portable

Stop copying CLAUDE.md. Start syncing it.

Synchronize your Claude Code contexts (CLAUDE.md, rules, skills) across all your projects and machines - like EnvMark for your AI contexts.

Quick Start • Documentation • Why ContextMark?

🚀 The Problem

Managing Claude Code contexts across 20+ repositories and 2 machines:

~/projects/
├── reposentinel/
│   └── CLAUDE.md  ← copied from backmark, modified since
├── backmark/
│   └── CLAUDE.md  ← "original" version but which one?
├── shipmark/
│   └── CLAUDE.md  ← outdated, forgot to update
├── new-project/
│   └── ???        ← start from scratch again
└── ~/.claude/
    ├── CLAUDE.md  ← global config, only on this machine
    └── rules/     ← lost if machine dies

Daily frustrations:

• Global config (~/.claude/) only exists on this machine
• Copy-paste between repos = inevitable divergence
• Two machines = double maintenance, guaranteed drift
• No backup of your carefully crafted Claude instructions

⚡ Quick Start

# Install globally
npm install -g @grazulex/contextmark

# Initialize your context library
contextmark init-library

# Save your global Claude config to the library
contextmark push --global

# Register and save a project
cd ~/projects/my-project
contextmark init
contextmark push

# Sync to Git remote (backup + cross-machine sync)
contextmark sync setup [email protected]:user/claude-configs.git
contextmark sync push

On another machine:

contextmark init-library
contextmark sync setup [email protected]:user/claude-configs.git
contextmark sync pull
contextmark pull --global   # Restore your global config

✨ Why ContextMark?

🔄 Simple Push/Pull

Like EnvMark for your Claude configs:

• push saves to library
• pull restores from library
• diff shows changes

🌐 Cross-Machine Sync

Git-based synchronization keeps your library in sync across all your development machines.

📁 Complete Backup

Back up everything:

• ~/.claude/CLAUDE.md
• ~/.claude/rules/*
• ~/.claude/skills/*
• Per-project configs

📝 Zero Lock-in

Standard Markdown and YAML files. No proprietary formats. Your context will be readable forever.

🛠 Commands

Simple Mode (Recommended)

# Global config (~/.claude/)
contextmark push --global       # Save to library
contextmark pull --global       # Restore from library
contextmark diff --global       # Compare

# Per-project config
cd ~/projects/my-project
contextmark init                # Register project
contextmark push                # Save to library
contextmark pull                # Restore from library
contextmark diff                # Compare
contextmark status              # Check sync status

# Sync with Git remote
contextmark sync setup <url>    # Configure remote
contextmark sync push           # Push to remote
contextmark sync pull           # Pull from remote
contextmark sync status         # Check remote status

Advanced Mode (Optional)

For power users managing 50+ projects with shared conventions:

# Create reusable blocks
contextmark block create laravel/base
contextmark blocks

# Create profiles (combinations of blocks)
contextmark profile create my-stack
contextmark profiles

# Initialize project with profile (generates CLAUDE.md)
contextmark init --profile my-stack
contextmark status              # Check for block updates
contextmark update              # Update from blocks
