OMC Setup

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

Graceful Interrupt Handling

IMPORTANT: This setup process saves progress after each step. If interrupted (Ctrl+C or connection loss), the setup can resume from where it left off.

State File Location

• .omc/state/setup-state.json - Tracks completed steps

Resume Detection (Step 0)

Before starting any step, check for existing state:

# Check for existing setup state
STATE_FILE=".omc/state/setup-state.json"

# Cross-platform ISO date to epoch conversion
iso_to_epoch() {
  local iso_date="$1"
  local epoch=""
  # Try GNU date first (Linux)
  epoch=$(date -d "$iso_date" +%s 2>/dev/null)
  if [ $? -eq 0 ] && [ -n "$epoch" ]; then
    echo "$epoch"
    return 0
  fi
  # Try BSD/macOS date
  local clean_date=$(echo "$iso_date" | sed 's/[+-][0-9][0-9]:[0-9][0-9]$//' | sed 's/Z$//' | sed 's/T/ /')
  epoch=$(date -j -f "%Y-%m-%d %H:%M:%S" "$clean_date" +%s 2>/dev/null)
  if [ $? -eq 0 ] && [ -n "$epoch" ]; then
    echo "$epoch"
    return 0
  fi
  echo "0"
}

if [ -f "$STATE_FILE" ]; then
  # Check if state is stale (older than 24 hours)
  TIMESTAMP_RAW=$(jq -r '.timestamp // empty' "$STATE_FILE" 2>/dev/null)
  if [ -n "$TIMESTAMP_RAW" ]; then
    TIMESTAMP_EPOCH=$(iso_to_epoch "$TIMESTAMP_RAW")
    NOW_EPOCH=$(date +%s)
    STATE_AGE=$((NOW_EPOCH - TIMESTAMP_EPOCH))
  else
    STATE_AGE=999999  # Force fresh start if no timestamp
  fi
  if [ "$STATE_AGE" -gt 86400 ]; then
    echo "Previous setup state is more than 24 hours old. Starting fresh."
    rm -f "$STATE_FILE"
  else
    LAST_STEP=$(jq -r ".lastCompletedStep // 0" "$STATE_FILE" 2>/dev/null || echo "0")
    TIMESTAMP=$(jq -r .timestamp "$STATE_FILE" 2>/dev/null || echo "unknown")
    echo "Found previous setup session (Step $LAST_STEP completed at $TIMESTAMP)"
  fi
fi

If state exists, 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":

rm -f ".omc/state/setup-state.json"
echo "Previous state cleared. Starting fresh setup."

Save Progress Helper

After completing each major step, save progress:

# Save setup progress (call after each step)
# Usage: save_setup_progress STEP_NUMBER
save_setup_progress() {
  mkdir -p .omc/state
  cat > ".omc/state/setup-state.json" << EOF
{
  "lastCompletedStep": $1,
  "timestamp": "$(date -Iseconds)",
  "configType": "${CONFIG_TYPE:-unknown}"
}
EOF
}

Clear State on Completion

After successful setup completion (Step 7/8), remove the state file:

rm -f ".omc/state/setup-state.json"
echo "Setup completed successfully. State cleared."

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)

Note: If resuming and lastCompletedStep >= 1, skip to the appropriate step based on configType.

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")

# Backup existing CLAUDE.md before overwriting (if it exists)
if [ -f ".claude/CLAUDE.md" ]; then
  BACKUP_DATE=$(date +%Y-%m-%d)
  BACKUP_PATH=".claude/CLAUDE.md.backup.${BACKUP_DATE}"
  cp .claude/CLAUDE.md "$BACKUP_PATH"
  echo "Backed up existing CLAUDE.md to $BACKUP_PATH"
fi

# 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.

Note: If an existing CLAUDE.md is found, it will be backed up to .claude/CLAUDE.md.backup.YYYY-MM-DD before downloading the new version.

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, save progress and report:

# Save progress - Step 2 complete (Local config)
mkdir -p .omc/state
cat > ".omc/state/setup-state.json" << EOF
{
  "lastCompletedStep": 2,
  "timestamp": "$(date -Iseconds)",
  "configType": "local"
}
EOF

OMC Project Configuration Complete

• CLAUDE.md: Updated with latest configuration from GitHub at ./.claude/CLAUDE.md
• Backup: Previous CLAUDE.md backed up to .claude/CLAUDE.md.backup.YYYY-MM-DD (if existed)
• 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, clear state and STOP HERE:

rm -f ".omc/state/setup-state.json"

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")

# Backup existing CLAUDE.md before overwriting (if it exists)
if [ -f "$HOME/.claude/CLAUDE.md" ]; then
  BACKUP_DATE=$(date +%Y-%m-%d)
  BACKUP_PATH="$HOME/.claude/CLAUDE.md.backup.${BACKUP_DATE}"
  cp "$HOME/.claude/CLAUDE.md" "$BACKUP_PATH"
  echo "Backed up existing CLAUDE.md to $BACKUP_PATH"
fi

# 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

Note: If an existing CLAUDE.md is found, it will be backed up to ~/.claude/CLAUDE.md.backup.YYYY-MM-DD before downloading the new version.

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, save progress and report:

# Save progress - Step 2 complete (Global config)
mkdir -p .omc/state
cat > ".omc/state/setup-state.json" << EOF
{
  "lastCompletedStep": 2,
  "timestamp": "$(date -Iseconds)",
  "configType": "global"
}
EOF

OMC Global Configuration Complete

• CLAUDE.md: Updated with latest configuration from GitHub at ~/.claude/CLAUDE.md
• Backup: Previous CLAUDE.md backed up to ~/.claude/CLAUDE.md.backup.YYYY-MM-DD (if existed)
• 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, clear state and STOP HERE:

rm -f ".omc/state/setup-state.json"

Do not continue to HUD setup or other steps.

Step 3: Setup HUD Statusline

Note: If resuming and lastCompletedStep >= 3, skip to Step 3.5.

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

After HUD setup completes, save progress:

# Save progress - Step 3 complete (HUD setup)
mkdir -p .omc/state
