# OMC Setup

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

## 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="$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 the download/merge script from Step 2A
- If only global exists, run the download/merge script from Step 2B
- Skip all other steps
- Report success and exit

**If user chooses "Run full setup again":**
- Continue with Step 0 (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.

## Graceful Interrupt Handling

**IMPORTANT**: This setup process saves progress after each step. If interrupted (Ctrl+C or
