agent-sync

Synchronize rules, skills, settings, and MCP servers across Claude Code, Cursor, Gemini, OpenCode, and Codex — in real-time.

Edit rules, skills, or MCP servers in any AI agent → they automatically sync to all others. Global Claude settings propagate to configured repos for Claude Code web access.

Installation

Works on macOS, Linux, and Windows (native + WSL).

pip install agent-rules-sync

uv pip install agent-rules-sync   # faster

The daemon installs and starts automatically as a system service.

CLI

agent-sync                         # start/ensure daemon is running
agent-sync sync                    # one-shot sync: rules + skills + settings + mcp
agent-sync sync rules              # sync only CLAUDE.md / rules files
agent-sync sync skills             # sync only skills directories
agent-sync sync settings           # sync only .claude/settings.json + hooks
agent-sync sync mcp                # sync only mcp.json / MCP server configs
agent-sync sync history            # import agent-run shell commands into Atuin
agent-sync sync rules skills       # multiple scopes
agent-sync setup                   # TUI wizard to configure sync directions
agent-sync status                  # daemon and sync status
agent-sync stop                    # stop daemon
agent-sync watch                   # watch in foreground (debugging)

agent-rules-sync also works as an alias for backwards compatibility.

What Gets Synced

1. Rules (CLAUDE.md, GEMINI.md, etc.)

Rules sync bidirectionally across all agent config files. Changes from any agent propagate to all others within 3 seconds.

# Shared Rules
- use pydantic for validation      ← syncs to all agents

## Claude Code Specific
- claude-specific rule             ← stays in Claude only

Monitored locations:

Repo-specific CLAUDE.md files can be added via repo_paths.json (see Configuration).

2. Skills

Skills are directories containing a SKILL.md file. Synced across all frameworks:

Newest version wins. Add a skill anywhere and the daemon syncs it to the other locations automatically.

3. Settings & Hooks (Claude Code)

Syncs a portable version of ~/.claude/settings.json to configured repos' .claude/settings.json:

• Strips machine-specific keys (statusLine, spinnerVerbs, remote, etc.)
• Strips permission rules with absolute paths
• Rewrites hook commands from ~/.claude/hooks/foo.sh → .claude/hooks/foo.sh
• Copies hook scripts into the repo's .claude/hooks/

This enables full tool permissions and hooks when using Claude Code web on those repos.

4. MCP Servers (mcp.json)

Synchronizes your MCP server list (under the mcpServers key) across all agents and the Claude Desktop. Any server added in Cursor or via claude mcp add becomes available everywhere.

Project-specific MCP servers in .mcp.json, .cursor/mcp.json, or .gemini/mcp.json are also merged into the global master list and synced across agents.

5. Agent Command History (Atuin)

Imports shell commands run by coding agents into Atuin so they show up in zsh reverse search alongside normal terminal history. The importer reads local transcript stores, writes a normalized append-only log at ~/.config/agent-rules-sync/agent-command-history.jsonl, and inserts new commands into ~/.local/share/atuin/history.db.

Supported transcript sources:

Current stable Atuin releases do not yet expose first-class agent metadata in search, so imported commands include a harmless trailing tag like # agent:codex. Newer Atuin builds with author / intent columns receive those fields directly.

The daemon watches these transcript roots too. When a transcript changes it imports only the changed transcript into the JSONL log and Atuin, without running a rules/skills/settings sync.

Configuration

Repo Paths

Add repos to sync rules, skills, and settings into:

~/.config/agent-rules-sync/repo_paths.json

["~/Code/my-project", "~/Code/another-repo"]

Each repo gets:

• <repo>/CLAUDE.md — synced from global rules
• <repo>/.cursorrules — legacy Cursor rules file; mirrored from the same content as global.mdc (optional; Cursor prefers .cursor/rules/)
• <repo>/.claude/skills/ — synced from master skills
• <repo>/.claude/settings.json — portable settings (auto-generated)
• <repo>/.claude/hooks/ — hook scripts (copied from ~/.claude/hooks/)

Sync Directions

Configure per-component direction via agent-sync setup (TUI wizard) or edit directly:

~/.config/agent-rules-sync/sync_config.json

{
  "mode": "default",
  "components": {
    "rules":    { "direction": "bidirectional", "enabled": true },
    "skills":   { "direction": "bidirectional", "enabled": true },
    "settings": { "direction": "push",          "enabled": true },
    "hooks":    { "direction": "push",           "enabled": true },
    "mcp":      { "direction": "bidirectional", "enabled": true }
  }
}

Directions:

Settings and hooks only support push (they are generated from global config).

Settings Strip Rules

Customize which keys/paths are stripped when generating portable settings:

~/.config/agent-rules-sync/settings_sync.json

{
  "strip_keys": ["statusLine", "spinnerVerbs", "remote"],
  "strip_path_prefixes": ["/Users/", "/home/", "/opt/homebrew/"],
  "sync_hooks": true,
  "hook_script_dir": ".claude/hooks"
}

Setup Wizard

Run agent-sync setup for a guided TUI to configure sync directions:

┌──────────────────────────────────────────────────────────┐
│ agent-sync  ·  Setup Wizard                              │
└──────────────────────────────────────────────────────────┘

  ── Sync Mode ───────────────────────────────────────────

  default       Rules/skills are bidirectional (newest wins).
                Settings/hooks push from global → repos.

  per_component Configure each component independently.

  Choice [1-2] (Enter = default):

Commands Reference

How It Works

~/.claude/settings.json         ~/.claude/CLAUDE.md        ~/.claude/skills/
        │                               │                         │
        │  strip machine-specific       │  merge shared +         │  newest
        │  rewrite hook paths           │  agent-specific         │  version
        ▼                               ▼                         ▼
  repo/.claude/             all agent CLAUDE.md          all framework
  settings.json             GEMINI.md AGENTS.md          skills/ dirs
  hooks/                    (9+ locations)               (6+ locations)

Daemon watches all locations with filesystem events. A slow periodic rescan is kept as a fallback for missed events or platforms without an event backend.

Backups

Every file change is backed up with a timestamp:

~/.config/agent-rules-sync/backups/     ← rules backups
~/.config/agent-rules-sync/skill_backups/  ← skills backups

Restore any version:

cp ~/.config/agent-rules-sync/backups/claude_20260125_014532.md ~/.claude/CLAUDE.md

Troubleshooting

agent-sync status              # check daemon + sync status
tail -f ~/.config/agent-rules-sync/daemon.log   # live logs
agent-sync stop && agent-sync  # restart daemon
agent-sync watch               # run in foreground for debugging

Uninstall

curl -fsSL https://raw.githubusercontent.com/dhruv-anand-aintech/agent-rules-sync/main/uninstall.sh | bash

Or manually:

agent-sync stop
pip uninstall -y agent-rules-sync
rm -rf ~/.config/agent-rules-sync

Agent rule files and repos are not touched.
