Sync between Claude Code, Codex and other coding agents and skills.

Install

bunx sync-agents

Or install globally:

bun install -g sync-agents

Then run directly:

sync-agents

Usage

sync-agents [options]

Flags

| Flag | Description | |------|-------------| | --global | Sync only global setup (~/.claude ↔ ~/.agents) | | --local | Sync only current folder (CLAUDE.md ↔ AGENTS.md) | | --source <dir> | Custom Claude source directory (default: ~/.claude) | | --dry-run | Preview changes without writing any files | | --no-cleanup | Skip removing skills from ~/.codex after migration |

Examples

# Sync everything (global setup + current folder)
sync-agents

# Preview what would be synced without making changes
sync-agents --dry-run

# Sync only global skills and agents
sync-agents --global

# Sync only project docs (CLAUDE.md ↔ AGENTS.md)
sync-agents --local

# Use a custom Claude directory
sync-agents --source ~/my-claude-config

# Migrate from .codex but keep the original files
sync-agents --no-cleanup

# Combine flags
sync-agents --global --dry-run

What it does

Directory Precedence

1. ~/.claude — Highest precedence (source of truth)
2. ~/.agents — Shared standard, syncs bidirectionally with Claude
3. ~/.codex — Legacy, migrates to .agents then gets cleaned up

• Claude → Agents: Skills and agents from ~/.claude sync to ~/.agents/skills. Claude wins on conflicts.
• Codex → Agents: Legacy ~/.codex/skills migrate to ~/.agents/skills (additive only).
• Agents → Claude: Skills from .agents that don't exist in Claude sync back (additive only).
• Cleanup: After migration, skills are removed from .codex (use --no-cleanup to preserve).

Project Docs

If the current directory has both CLAUDE.md and AGENTS.md, the most recently modified file overwrites the other.

Why?

The .agents folder is becoming the shared standard for coding agents. Codex now reads skills from ~/.agents/skills natively, but Claude Code doesn't support it yet.

This tool bridges the gap:

• Maintain skills in Claude Code's format (your source of truth)
• Auto-sync to .agents for Codex compatibility
• Migrate existing .codex skills to the new standard
• Keep project docs in sync

Requirements

• Bun runtime
