sync-claude-skills-to-codex

Sync Claude Code skills to Codex CLI via symlinks. Share your skill library between both AI coding assistants.

What it does

• Creates symlinks from ~/.codex/skills/ to your Claude Code skills
• Syncs both plugin skills (~/.claude/plugins/cache/) and personal skills (~/.claude/skills/)
• Includes list-skills enumerator for skill discovery
• Handles plugin version changes (re-run after updates)

Installation

From GitHub (recommended)

# Step 1: Add the marketplace
/plugin marketplace add ariccb/sync-claude-skills-to-codex

# Step 2: Install the plugin
/plugin install sync-claude-skills-to-codex@ariccb-ai-tools

Manual installation

Clone and copy the skill to your personal skills directory:

git clone https://github.com/ariccb/sync-claude-skills-to-codex.git
mkdir -p ~/.claude/skills
cp -r sync-claude-skills-to-codex/sync-claude-skills-to-codex/skills/sync-claude-skills-to-codex ~/.claude/skills/

Usage

In Claude Code or Codex, run:

/sync-claude-skills-to-codex

The skill will:

1. Find all Claude Code skills (plugins + personal)
2. Create symlinks in ~/.codex/skills/
3. Install list-skills enumerator in ~/bin/

Options

• /sync-claude-skills-to-codex — Run full sync
• /sync-claude-skills-to-codex list — List current skills without syncing
• /sync-claude-skills-to-codex --dry-run — Show what would be synced

List skills

After installation, use the enumerator:

list-skills           # Human-readable list
list-skills --json    # JSON output for tooling

Why symlinks?

Both Claude Code and Codex use identical SKILL.md formats (YAML frontmatter + markdown). Symlinks mean:

• Changes to source skills instantly reflect in both tools
• No disk space duplication
• Single source of truth

Re-running after plugin updates

When Claude Code plugins update versions, symlinks may break. Just re-run:

/sync-claude-skills-to-codex
