Skillshare: Sync Your AI CLI Skills Across Claude, Codex, Cursor, Gemini, and OpenCode

#opensource #cli #productivity #ai

Are you using multiple AI coding assistants? Tired of manually copying skills between .claude/skills, .codex/skills, and other CLI tools?

Skillshare is a simple CLI tool that syncs your AI skills from a single source to all your favorite AI tools.

The Problem

Modern developers often use multiple AI assistants:

Claude Code (.claude/skills)
Codex CLI (.codex/skills)
Cursor (.cursor/skills)
Gemini CLI (.gemini/antigravity/skills)
OpenCode (.config/opencode/skill)

Each has its own skills directory. Keeping them in sync is tedious.

The Solution

# Install
brew install runkids/tap/skillshare

# Initialize with interactive setup
skillshare init

# Sync your skills everywhere
skillshare sync

Key Features

Single Source of Truth — Write skills once, use everywhere
Two Sync Modes:
- symlink — Link entire directory (all targets identical)
- merge — Per-skill symlinks (preserve local customizations)
Auto-detection — Finds installed AI CLIs automatically
Backup & Restore — Never lose your existing skills
Doctor Command — Diagnose sync issues instantly

Quick Start

# 1. Initialize (detects your AI tools)
skillshare init

# 2. Check what will sync
skillshare status

# 3. Preview changes
skillshare diff

# 4. Sync!
skillshare sync

Example Workflow

$ skillshare status

Source: ~/.config/skillshare/skills (3 skills)
  ├── commit-helper
  ├── code-review
  └── debugging

Targets:
  ✓ claude   ~/.claude/skills              (symlinked)
  ✓ codex    ~/.codex/skills               (symlinked)
  ✓ opencode ~/.config/opencode/skill      (symlinked)
  ○ cursor   ~/.cursor/skills              (not synced)

Why Skillshare?

Without Skillshare	With Skillshare
Copy files manually	`skillshare sync`
Forget which tool has latest	Single source
