# 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.

```bash
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:

```bash
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.

```bash
# 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/CLAUD
