CapSync

A simple tool to sync your AI coding skills across different tools.

The Problem

Different AI coding tools store skills in different folders:

Tool	Skills Folder
OpenCode	~/.config/opencode/skill/
ClaudeCode	~/.claude/skills/
Cursor	~/.cursor/skills/
Codex	~/.codex/skills/
Amp	~/.agents/skills/
Antigravity	~/.agent/skills/

Managing the same skills in all these places is annoying.

The Solution

Keep your skills in one place and let CapSync sync them everywhere.

Installation

Download Binary (Easy)

1. Go to Releases
2. Download for your system:
   • cap_sync-linux-x86_64 for Linux
   • cap_sync-darwin-x86_64 for Mac Intel
   • cap_sync-darwin-aarch64 for Mac Apple Silicon
3. Make it executable:

   chmod +x cap_sync-*
   sudo mv cap_sync-* /usr/local/bin/capsync

Build From Source

git clone https://github.com/pixincreate/CapSync.git
cd cap_sync
cargo install --path .

Quick Start

# Set up config
capsync init

# See which tools you have
capsync detect-tools

# Sync your skills
capsync sync

# Check what's synced
capsync status

Commands

capsync init

Creates the config file with sensible defaults.

capsync config

Shows your current settings.

capsync detect-tools

Checks which AI coding tools are installed.

capsync sync

Copies your skills to all enabled tools using symlinks.

capsync status

Shows what's currently synced.

Configuration

Config file is at ~/.config/capsync/config.toml:

[source]
directory = "~/Dev/scripts/skills/skills"

[tools]
opencode = { enabled = true, path = "~/.config/opencode/skill" }
claude = { enabled = true, path = "~/.claude/skills" }
codex = { enabled = false, path = "~/.codex/skills" }
cursor = { enabled = false, path = "~/.cursor/skills" }

Change:

• directory: Where your skills are stored
• enabled: Turn tools on/off
• path: Where each tool keeps its skills

How It Works

1. You put skills in one folder
2. CapSync creates symlinks from that folder to each tool's skills folder
3. Update your skills in one place, they're available everywhere

Skill Format

Each skill is a folder with a SKILL.md file:

my-skill/
└── SKILL.md

The SKILL.md needs this header:

---
name: my-skill
description: What this skill does
license: MIT
---

# My Skill
