omc-setup

OMC Setup

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

Usage Modes

This skill handles three scenarios:

1. Initial Setup (no flags): First-time installation wizard
2. Local Configuration (--local): Configure project-specific settings (.claude/CLAUDE.md)
3. Global Configuration (--global): Configure global settings (~/.claude/CLAUDE.md)

Mode Detection

Check for flags in the user's invocation:

• If --local flag present → Skip to Local Configuration (Step 2A)
• If --global flag present → Skip to Global Configuration (Step 2B)
• If no flags → Run Initial Setup wizard (Step 1)

Step 1: Initial Setup Wizard (Default Behavior)

Use the AskUserQuestion tool to prompt the user:

Question: "Where should I configure oh-my-claudecode?"

Options:

1. Local (this project) - Creates .claude/CLAUDE.md in current project directory. Best for project-specific configurations.
2. Global (all projects) - Creates ~/.claude/CLAUDE.md for all Claude Code sessions. Best for consistent behavior everywhere.

Step 2A: Local Configuration (--local flag or user chose LOCAL)

CRITICAL: This ALWAYS downloads fresh CLAUDE.md from GitHub to the local project. DO NOT use the Write tool - use bash curl exclusively.

Create Local .claude Directory

# Create .claude directory in current project
mkdir -p .claude && echo ".claude directory ready"

Download Fresh CLAUDE.md

# Extract old version before download
OLD_VERSION=$(grep -m1 "^# oh-my-claudecode" .claude/CLAUDE.md 2>/dev/null | grep -oE 'v[0-9]+\.[0-9]+\.[0-9]+' || echo "none")

# Download fresh CLAUDE.md from GitHub
curl -fsSL "https://raw.githubusercontent.com/Yeachan-Heo/oh-my-claudecode/main/docs/CLAUDE.md" -o .claude/CLAUDE.md && \
echo "Downloaded CLAUDE.md to .claude/CLAUDE.md"

# Extract new version and report
NEW_VERSION=$(grep -m1 "^# oh-my-claudecode" .claude/CLAUDE.md 2>/dev/null | grep -oE 'v[0-9]+\.[0-9]+\.[0-9]+' || echo "unknown")
if [ "$OLD_VERSION" = "none" ]; then
  echo "Installed CLAUDE.md: $NEW_VERSION"
elif [ "$OLD_VERSION" = "$NEW_VERSION" ]; then
  echo "CLAUDE.md unchanged: $NEW_VERSION"
else
  echo "Updated CLAUDE.md: $OLD_VERSION -> $NEW_VERSION"
fi

Note: The downloaded CLAUDE.md includes Context Persistence instructions with <remember> tags for surviving conversation compaction.

MANDATORY: Always run this command. Do NOT skip. Do NOT use Write tool.

FALLBACK if curl fails: Tell user to manually download from: https://raw.githubusercontent.com/Yeachan-Heo/oh-my-claudecode/main/docs/CLAUDE.md

Verify Plugin Installation

grep -q "oh-my-claudecode" ~/.claude/settings.json && echo "Plugin verified" || echo "Plugin NOT found - run: claude /install-plugin oh-my-claudecode"

Confirm Local Configuration Success

After completing local configuration, report:

OMC Project Configuration Complete

• CLAUDE.md: Updated with latest configuration from GitHub at ./.claude/CLAUDE.md
• Scope: PROJECT - applies only to this project
• Hooks: Provided by plugin (no manual installation needed)
• Agents: 28+ available (base + tiered variants)
• Model routing: Haiku/Sonnet/Opus based on task complexity

Note: This configuration is project-specific and won't affect other projects or global settings.

If --local flag was used, STOP HERE. Do not continue to HUD setup or other steps.

Step 2B: Global Configuration (--global flag or user chose GLOBAL)

CRITICAL: This ALWAYS downloads fresh CLAUDE.md from GitHub to global config. DO NOT use the Write tool - use bash curl exclusively.

Download Fresh CLAUDE.md

# Extract old version before download
OLD_VERSION=$(grep -m1 "^# oh-my-claudecode" ~/.claude/CLAUDE.md 2>/dev/null | grep -oE 'v[0-9]+\.[0-9]+\.[0-9]+' || echo "none")

# Download fresh CLAUDE.md to global config
curl -fsSL "https://raw.githubusercontent.com/Yeachan-Heo/oh-my-claudecode/main/docs/CLAUDE.md" -o ~/.claude/CLAUDE.md && \
echo "Downloaded CLAUDE.md to ~/.claude/CLAUDE.md"

# Extract new version and report
NEW_VERSION=$(grep -m1 "^# oh-my-claudecode" ~/.claude/CLAUDE.md 2>/dev/null | grep -oE 'v[0-9]+\.[0-9]+\.[0-9]+' || echo "unknown")
if [ "$OLD_VERSION" = "none" ]; then
  echo "Installed CLAUDE.md: $NEW_VERSION"
elif [ "$OLD_VERSION" = "$NEW_VERSION" ]; then
  echo "CLAUDE.md unchanged: $NEW_VERSION"
else
  echo "Updated CLAUDE.md: $OLD_VERSION -> $NEW_VERSION"
fi

Clean Up Legacy Hooks (if present)

Check if old manual hooks exist and remove them to prevent duplicates:

# Remove legacy bash hook scripts (now handled by plugin system)
rm -f ~/.claude/hooks/keyword-detector.sh
rm -f ~/.claude/hooks/stop-continuation.sh
rm -f ~/.claude/hooks/persistent-mode.sh
rm -f ~/.claude/hooks/session-start.sh
echo "Legacy hooks cleaned"

Check ~/.claude/settings.json for manual hook entries. If the "hooks" key exists with UserPromptSubmit, Stop, or SessionStart entries pointing to bash scripts, inform the user:

Note: Found legacy hooks in settings.json. These should be removed since the plugin now provides hooks automatically. Remove the "hooks" section from ~/.claude/settings.json to prevent duplicate hook execution.

Verify Plugin Installation

grep -q "oh-my-claudecode" ~/.claude/settings.json && echo "Plugin verified" || echo "Plugin NOT found - run: claude /install-plugin oh-my-claudecode"

Confirm Global Configuration Success

After completing global configuration, report:

OMC Global Configuration Complete

• CLAUDE.md: Updated with latest configuration from GitHub at ~/.claude/CLAUDE.md
• Scope: GLOBAL - applies to all Claude Code sessions
• Hooks: Provided by plugin (no manual installation needed)
• Agents: 28+ available (base + tiered variants)
• Model routing: Haiku/Sonnet/Opus based on task complexity

Note: Hooks are now managed by the plugin system automatically. No manual hook installation required.

If --global flag was used, STOP HERE. Do not continue to HUD setup or other steps.

Step 3: Setup HUD Statusline

The HUD shows real-time status in Claude Code's status bar. Invoke the hud skill to set up and configure:

Use the Skill tool to invoke: hud with args: setup

This will:

1. Install the HUD wrapper script to ~/.claude/hud/omc-hud.mjs
2. Configure statusLine in ~/.claude/settings.json
3. Report status and prompt to restart if needed

Step 3.5: Clear Stale Plugin Cache

Clear old cached plugin versions to avoid conflicts:

# Clear stale plugin cache versions
CACHE_DIR="$HOME/.claude/plugins/cache/omc/oh-my-claudecode"
if [ -d "$CACHE_DIR" ]; then
  LATEST=$(ls -1 "$CACHE_DIR" | sort -V | tail -1)
  CLEARED=0
  for dir in "$CACHE_DIR"/*; do
    if [ "$(basename "$dir")" != "$LATEST" ]; then
      rm -rf "$dir"
      CLEARED=$((CLEARED + 1))
    fi
  done
  [ $CLEARED -gt 0 ] && echo "Cleared $CLEARED stale cache version(s)" || echo "Cache is clean"
else
  echo "No cache directory found (normal for new installs)"
fi

Step 3.6: Check for Updates

Notify user if a newer version is available:

# Detect installed version
INSTALLED_VERSION=""

# Try cache directory first
if [ -d "$HOME/.claude/plugins/cache/omc/oh-my-claudecode" ]; then
  INSTALLED_VERSION=$(ls -1 "$HOME/.claude/plugins/cache/omc/oh-my-claudecode" | sort -V | tail -1)
fi

# Try .omc-version.json second
if [ -z "$INSTALLED_VERSION" ] && [ -f ".omc-version.json" ]; then
  INSTALLED_VERSION=$(grep -oE '"version":\s*"[^"]+' .omc-version.json | cut -d'"' -f4)
fi

# Try CLAUDE.md header third (local first, then global)
if [ -z "$INSTALLED_VERSION" ]; then
  if [ -f ".claude/CLAUDE.md" ]; then
    INSTALLED_VERSION=$(grep -m1 "^# oh-my-claudecode" .claude/CLAUDE.md 2>/dev/null | grep -oE 'v[0-9]+\.[0-9]+\.[0-9]+' | sed 's/^v//')
  elif [ -f "$HOME/.claude/CLAUDE.md" ]; then
    INSTALLED_VERSION=$(grep -m1 "^# oh-my-claudecode" "$HOME/.claude/CLAUDE.md" 2>/dev/null | grep -oE 'v[0-9]+\.[0-9]+\.[0-9]+' | sed 's/^v//')
  fi
fi

# Check npm for latest version
LATEST_VERSION=$(npm view oh-my-claude-sisyphus version 2>/dev/null)

if [ -n "$INSTALLED_VERSION" ] && [ -n "$LATEST_VERSION" ]; then
  # Simple version comparison (assumes semantic versioning)
  if [ "$INSTALLED_VERSION" != "$LATEST_VERSION" ]; then
    echo ""
    echo "UPDATE AVAILABLE:"
    echo "  Installed: v$INSTALLED_VERSION"
    echo "  Latest:    v$LATEST_VERSION"
    echo ""
    echo "To update, run: claude /install-plugin oh-my-claudecode"
  else
    echo "You're on the latest version: v$INSTALLED_VERSION"
  fi
elif [ -n "$LATEST_VERSION" ]; then
  echo "Latest version available: v$LATEST_VERSION"
fi

Step 3.7: Set Default Execution Mode

Use the AskUserQuestion tool to prompt the user:

Question: "Which parallel execution mode should be your default when you say 'fast' or 'parallel'?"

Options:

1. ultrawork (maximum capability) - Uses all agent tiers including Opus for complex tasks. Best for challenging work where quality matters most. (Recommended)
2. ecomode (token efficient) - Prefers Haiku/Sonnet agents, avoids Opus. Best for pro-plan users who want cost efficiency.

Store the preference in ~/.claude/.omc-config.json:

# Read existing config or create empty object
CONFIG_FILE="$HOME/.claude/.omc-config.json"
mkdir -p "$(dirname "$CONFIG_FILE")"

if [ -f "$CONFIG_FILE" ]; then
  EXISTING=$(cat "$CONFIG_FILE")
else
  EXISTING='{}'
fi

# Set defaultExecutionMode (replace USER_CHOICE with "ultrawork" or "ecomode")
echo "$EXISTING" | jq --arg mode "USER_CHOICE" '. + {defaultExecutionMode: $mode, configuredAt: (now | todate)}' > "$CONFIG_FILE"
echo "Default execution mode set to: USER_CHOICE"

Note: This preference ONLY affects generic keywords ("fast", "parallel"). Explicit keywords ("ulw", "eco") always override this preference.

Step 4: Verify Plugin Installation

grep -q "oh-my-claudecode" ~/.claude/settings.json && echo "Plugin verified" || echo "Plugin NOT found - run: claude /install-plugin oh-my-claudecode"

Step 5: Offer MCP Server Configuration

MCP servers extend Claude Code with additional tools (web search, GitHub, etc.).

Ask user: "Would you like to configure MCP servers for enhanced capabilities? (Context7, Exa search, GitHub, etc.)"

If yes, invoke the mcp-setup skill:

/oh-my-claudecode:mcp-setup

If no, skip to next step.

Step 6: Detect Upgrade from 2.x

Check if user has existing configuration:

# Check for existing 2.x artifacts
ls ~/.claude/commands/ralph-loop.md 2>/dev/null || ls ~/.claude/commands/ultrawork.md 2>/dev/null

If found, this is an upgrade from 2.x.

Step 7: Show Welcome Message

For New Users:

OMC Setup Complete!

You don't need to learn any commands. I now have intelligent behaviors that activate automatically.

WHAT HAPPENS AUTOMATICALLY:
- Complex tasks -> I parallelize and delegate to specialists
- "plan this" -> I start a planning interview
- "don't stop until done" -> I persist until verified complete
- "stop" or "cancel" -> I intelligently stop current operation

MAGIC KEYWORDS (optional power-user shortcuts):
Just include these words naturally in your request:

| Keyword | Effect | Example |
|---------|--------|---------|
| ralph | Persistence mode | "ralph: fix the auth bug" |
| ralplan | Iterative planning | "ralplan this feature" |
| ulw | Max parallelism | "ulw refactor the API" |
| eco | Token-efficient mode | "eco refactor the API" |
| plan | Planning interview | "plan the new endpoints" |

Combine them: "ralph ulw: migrate the database"

MCP SERVERS:
Run /oh-my-claudecode:mcp-setup to add tools like web search, GitHub, etc.

HUD STATUSLINE:
The status bar now shows OMC state. Restart Claude Code to see it.

That's it! Just use Claude Code normally.

For Users Upgrading from 2.x:

OMC Setup Complete! (Upgraded from 2.x)

GOOD NEWS: Your existing commands still work!
- /ralph, /ultrawork, /planner, etc. all still function

WHAT'S NEW in 3.0:
You no longer NEED those commands. Everything is automatic now:
- Just say "don't stop until done" instead of /ralph
- Just say "fast" or "parallel" instead of /ultrawork
- Just say "plan this" instead of /planner
- Just say "stop" instead of /cancel-ralph

MAGIC KEYWORDS (power-user shortcuts):
| Keyword | Same as old... | Example |
|---------|----------------|---------|
| ralph | /ralph | "ralph: fix the bug" |
| ralplan | /ralplan | "ralplan this feature" |
| ulw | /ultrawork | "ulw refactor API" |
| eco | (new!) | "eco fix all errors" |
| plan | /planner | "plan the endpoints" |

HUD STATUSLINE:
The status bar now shows OMC state. Restart Claude Code to see it.

Your workflow won't break - it just got easier!

Step 8: Ask About Starring Repository

First, check if gh CLI is available and authenticated:

gh auth status &>/dev/null

If gh is available and authenticated:

Use the AskUserQuestion tool to prompt the user:

Question: "If you're enjoying oh-my-claudecode, would you like to support the project by starring it on GitHub?"

Options:

1. Yes, star it! - Star the repository
2. No thanks - Skip without further prompts
3. Maybe later - Skip without further prompts

If user chooses "Yes, star it!":

gh api -X PUT /user/starred/Yeachan-Heo/oh-my-claudecode 2>/dev/null && echo "Thanks for starring! ⭐" || true

Note: Fail silently if the API call doesn't work - never block setup completion.

If gh is NOT available or not authenticated:

echo ""
echo "If you enjoy oh-my-claudecode, consider starring the repo:"
echo "  https://github.com/Yeachan-Heo/oh-my-claudecode"
echo ""

Keeping Up to Date

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

• /oh-my-claudecode:omc-setup --local to update project config
• /oh-my-claudecode:omc-setup --global to update global config

This ensures you have the newest features and agent configurations.
