OMC Setup

OMC Setup

This is the only command you need to learn. After running this, everything else is automatic.

When this skill is invoked, immediately execute the workflow below. Do not only restate or summarize these instructions back to the user.

Note: All ~/​.claude/​... paths in this guide respect CLAUDE_CONFIG_DIR when that environment variable is set.

Best-Fit Use

Choose this setup flow when the user wants to install, refresh, or repair OMC itself.

• Marketplace/​plugin install users should land here after /​plugin install oh-my-claudecode
• npm users should land here after npm i -g oh-my-claude-sisyphus@latest
• local-dev and worktree users should land here after updating the checked-out repo and rerunning setup

Flag Parsing

Check for flags in the user's invocation:

• --help → Show Help Text (below) and stop
• --local → Phase 1 only (target=local), then stop
• --global → Phase 1 only (target=global), then stop
• --force → Skip Pre-Setup Check, run full setup (Phase 1 → 2 → 3 → 4)
• No flags → Run Pre-Setup Check, then full setup if needed

Help Text

When user runs with --help, display this and stop:

OMC Setup - Configure oh-my-claudecode

USAGE:
  /​oh-my-claudecode:omc-setup           Run initial setup wizard (or update if already configured)
  /​oh-my-claudecode:omc-setup --local   Configure local project (.claude/​CLAUDE.md)
  /​oh-my-claudecode:omc-setup --global  Configure global settings (~/​.claude/​CLAUDE.md)
  /​oh-my-claudecode:omc-setup --force   Force full setup wizard even if already configured
  /​oh-my-claudecode:omc-setup --help    Show this help

MODES:
  Initial Setup (no flags)
    - Interactive wizard for first-time setup
    - Configures CLAUDE.md (local or global)
    - Sets up HUD statusline
    - Checks for updates
    - Offers MCP server configuration
    - Configures team mode defaults (agent count, type, model)
    - If already configured, offers quick update option

  Local Configuration (--local)
    - Downloads fresh CLAUDE.md to ./​.claude/
    - Backs up existing CLAUDE.md to .claude/​CLAUDE.md.backup.YYYY-MM-DD
    - Project-specific settings
    - Use this to update project config after OMC upgrades

  Global Configuration (--global)
    - Downloads fresh CLAUDE.md to ~/​.claude/
    - Backs up existing CLAUDE.md to ~/​.claude/​CLAUDE.md.backup.YYYY-MM-DD
    - Default: explicitly overwrites ~/​.claude/​CLAUDE.md so plain `claude` also uses OMC
    - Optional preserve mode keeps the user's base `CLAUDE.md` and installs OMC into `CLAUDE-omc.md` for `omc` launches
    - Applies to all Claude Code sessions
    - Cleans up legacy hooks
    - Use this to update global config after OMC upgrades

  Force Full Setup (--force)
    - Bypasses the "already configured" check
    - Runs the complete setup wizard from scratch
    - Use when you want to reconfigure preferences

EXAMPLES:
  /​oh-my-claudecode:omc-setup           # First time setup (or update CLAUDE.md if configured)
  /​oh-my-claudecode:omc-setup --local   # Update this project
  /​oh-my-claudecode:omc-setup --global  # Update all projects
  /​oh-my-claudecode:omc-setup --force   # Re-run full setup wizard

Active Plugin Root Resolution

Before running setup shell commands or reading phase files, resolve the current OMC plugin root. This prevents an already-running Claude Code session from continuing to use a stale CLAUDE_PLUGIN_ROOT after /​plugin marketplace update omc installs a newer cache version.

OMC_SETUP_PLUGIN_ROOT=$(node -e "const f=require('fs'),p=require('path'),h=require('os').homedir(),d=(process.env.CLAUDE_CONFIG_DIR||p.join(h,'.claude')).replace(/[\\/]+$/,''),b=p.join(d,'plugins','cache','omc','oh-my-claudecode'),valid=r=>f.existsSync(p.join(r,'skills','omc-setup','SKILL.md'))||f.existsSync(p.join(r,'hooks','hooks.json'))||f.existsSync(p.join(r,'docs','CLAUDE.md'));try{const vs=f.readdirSync(b,{withFileTypes:true}).filter(e=>(e.isDirectory()||e.isSymbolicLink())&&/^\d+\.\d+\.\d+/​.test(e.name)).map(e=>e.name).sort((a,c)=>c.localeCompare(a,void 0,{numeric:true}));const hit=vs.map(v=>p.join(b,v)).find(valid);if(hit)console.log(hit);else if(process.env.CLAUDE_PLUGIN_ROOT)console.log(process.env.CLAUDE_PLUGIN_ROOT)}catch{if(process.env.CLAUDE_PLUGIN_ROOT)console.log(process.env.CLAUDE_PLUGIN_ROOT)}")
export OMC_SETUP_PLUGIN_ROOT

Use ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}} for all setup script and phase paths, then immediately repair stale cache references before any prompts or phase work:

node "${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​scripts/​repair-plugin-cache.mjs"

Pre-Setup Check: Already Configured?

CRITICAL: Before doing anything else, check if setup has already been completed. This prevents users from having to re-run the full setup wizard after every update.

# Check if setup was already completed
CONFIG_FILE="${CLAUDE_CONFIG_DIR:-$HOME/​.claude}/​.omc-config.json"

if [ -f "$CONFIG_FILE" ]; then
  SETUP_COMPLETED=$(jq -r '.setupCompleted // empty' "$CONFIG_FILE" 2>/​dev/​null)
  SETUP_VERSION=$(jq -r '.setupVersion // empty' "$CONFIG_FILE" 2>/​dev/​null)

  if [ -n "$SETUP_COMPLETED" ] && [ "$SETUP_COMPLETED" != "null" ]; then
    echo "OMC setup was already completed on: $SETUP_COMPLETED"
    [ -n "$SETUP_VERSION" ] && echo "Setup version: $SETUP_VERSION"
    ALREADY_CONFIGURED="true"
  fi
fi

If Already Configured (and no --force flag)

If ALREADY_CONFIGURED is true AND the user did NOT pass --force, --local, or --global flags:

Use AskUserQuestion to prompt:

Question: "OMC is already configured. What would you like to do?"

Options:

1. Update CLAUDE.md only - Download latest CLAUDE.md without re-running full setup
2. Run full setup again - Go through the complete setup wizard
3. Cancel - Exit without changes

If user chooses "Update CLAUDE.md only":

• Detect if local (.claude/​CLAUDE.md) or global (~/​.claude/​CLAUDE.md) config exists
• If local exists, run: bash "${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​scripts/​setup-claude-md.sh" local
• If only global exists, run: bash "${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​scripts/​setup-claude-md.sh" global
• Skip all other steps
• Report success and exit

If user chooses "Run full setup again":

• Continue with Resume Detection below

If user chooses "Cancel":

• Exit without any changes

Force Flag Override

If user passes --force flag, skip this check and proceed directly to setup.

Resume Detection

Before starting any phase, check for existing state:

bash "${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​scripts/​setup-progress.sh" resume

If state exists (output is not "fresh"), use AskUserQuestion to prompt:

Question: "Found a previous setup session. Would you like to resume or start fresh?"

Options:

1. Resume from step $LAST_STEP - Continue where you left off
2. Start fresh - Begin from the beginning (clears saved state)

If user chooses "Start fresh":

bash "${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​scripts/​setup-progress.sh" clear

Phase Execution

For --local or --global flags:

Read the file at ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​skills/​omc-setup/​phases/​01-install-claude-md.md and follow its instructions. (The phase file handles early exit for flag mode.)

For full setup (default or --force):

Execute phases sequentially. For each phase, read the corresponding file and follow its instructions:

1. Phase 1 - Install CLAUDE.md: Read ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​skills/​omc-setup/​phases/​01-install-claude-md.md and follow its instructions.

2. Phase 2 - Environment Configuration: Read ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​skills/​omc-setup/​phases/​02-configure.md and follow its instructions. Phase 2 must delegate HUD/​statusLine setup to the hud skill; do not generate or patch statusLine paths inline here.

3. Phase 3 - Integration Setup: Read ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​skills/​omc-setup/​phases/​03-integrations.md and follow its instructions.

4. Phase 4 - Completion: Read ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​skills/​omc-setup/​phases/​04-welcome.md and follow its instructions.

Graceful Interrupt Handling

IMPORTANT: This setup process saves progress after each phase via ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/​scripts/​setup-progress.sh. If interrupted (Ctrl+C or connection loss), the setup can resume from where it left off.

Keeping Up to Date

After installing oh-my-claudecode updates (via npm or plugin update):

Automatic: Just run /​oh-my-claudecode:omc-setup - it will detect you've already configured and offer a quick "Update CLAUDE.md only" option that skips the full wizard.

Manual options:

• /​oh-my-claudecode:omc-setup --local to update project config only
• /​oh-my-claudecode:omc-setup --global to update global config only
• /​oh-my-claudecode:omc-setup --force to re-run the full wizard (reconfigure preferences)

This ensures you have the newest features and agent configurations without the token cost of repeating the full setup.
