HUD Skill

Configure the OMC HUD (Heads-Up Display) for the statusline.

Quick Commands

Auto-Setup

When you run /oh-my-claudecode:hud or /oh-my-claudecode:hud setup, the system will automatically:
1. Check if ~/.claude/hud/omc-hud.mjs exists
2. Check if statusLine is configured in ~/.claude/settings.json
3. If missing, create the HUD wrapper script and configure settings
4. Report status and prompt to restart Claude Code if changes were made

IMPORTANT: If the argument is setup OR if the HUD script doesn't exist at ~/.claude/hud/omc-hud.mjs, you MUST create the HUD files directly using the instructions below.

Setup Instructions (Run These Commands)

Step 1: Check if setup is needed:

ls ~/.claude/hud/omc-hud.mjs 2>/dev/null && echo "EXISTS" || echo "MISSING"

Step 2: Check if the plugin is built (CRITICAL - common issue!):

# Find the latest version and check if dist/hud/index.js exists
PLUGIN_VERSION=$(ls ~/.claude/plugins/cache/omc/oh-my-claudecode/ 2>/dev/null | sort -V | tail -1)
if [ -n "$PLUGIN_VERSION" ]; then
  ls ~/.claude/plugins/cache/omc/oh-my-claudecode/$PLUGIN_VERSION/dist/hud/index.js 2>/dev/null && echo "BUILT" || echo "NOT_BUILT"
fi

⚠️ CRITICAL: If NOT_BUILT, the plugin MUST be compiled before the HUD can work!

WHY THIS HAPPENS: The dist/ directory contains compiled TypeScript code and is NOT stored on GitHub (it's in .gitignore). When you install the plugin from the marketplace, the build step happens automatically via the prepare script during npm install. However, if the plugin wasn't properly installed or the build failed, you'll get this error.

THE FIX: Run npm install in the plugin directory to build it:

cd ~/.claude/plugins/cache/omc/oh-my-claudecode/$PLUGIN_VERSION && npm install

This will:
1. Install all dependencies
2. Run the prepare script which executes npm run build
3. Generate the dist/hud/index.js file that the HUD wrapper needs

DO NOT try to download dist/hud/index.js from GitHub raw URLs - it doesn't exist there!

Step 3: If omc-hud.mjs is MISSING or argument is setup, create the HUD directory and script:

First, create the directory:

mkdir -p ~/.claude/hud

Then, use the Write tool to create ~/.claude/hud/omc-hud.mjs with this exact content:

#!/usr/bin/env node
/**
 * OMC HUD - Statusline Script
 * Wrapper that imports from plugin cache or development paths
 */

import { existsSync, readdirSync } from "node:fs";
import { homedir } from "node:os";
import { join } from "node:path";
import { pathToFileURL } from "node:url";

// Semantic version comparison: returns negative if a < b, positive if a > b, 0 if equal
function semverCompare(a, b) {
  const pa = a.replace(/^v/, "").split(".").map(Number);
  const pb = b.replace(/^v/, "").split(".").map(Number);
  for (let i = 0; i < Math.max(pa.length, pb.length); i++) {
    const na = pa[i] || 0;
    const nb = pb[i] || 0;
    if (na !== nb) return na - nb;
  }
  return 0;
}

async function main() {
  const home = homedir();
  let pluginCacheDir = null;

  // 1. Try plugin cache first (marketplace: omc, plugin: oh-my-claudecode)
  const pluginCacheBase = join(home, ".claude/plugins/cache/omc/oh-my-claudecode");
  if (existsSync(pluginCacheBase)) {
    try {
      const versions = readdirSync(pluginCacheBase);
      if (versions.length > 0) {
        const latestVersion = versions.sort(semverCompare).reverse()[0];
        pluginCacheDir = join(pluginCacheBase, latestVersion);
        const pluginPath = join(pluginCacheDir, "dist/hud/index.js");
        if (existsSync(pluginPath)) {
          await import(pathToFileURL(pluginPath).href);
          return;
        }
      }
    } catch { /* continue */ }
  }

  // 2. Development paths
  const devPaths = [
    join(home, "Workspace/oh-my-claude-sisyphus/dist/hud/index.js"),
    join(home, "workspace/oh-my-claude-sisyphus/dist/hud/index.js"),
    join(home, "Workspace/oh-my-claudecode/dist/hud/index.js"),
    join(home, "workspace/oh-my-claudecode/dist/hud/index.js"),
  ];

  for (const devPath of devPaths) {
    if (existsSync(devPath)) {
      try {
        await import(pathToFileURL(devPath).href);
        return;
      } catch { /* continue */ }
    }
  }

  // 3. Fallback - HUD not found (provide actionable error message)
  if (pluginCacheDir) {
    console.log(`[OMC] HUD not built. Run: cd "${pluginCacheDir}" && npm install`);
  } else {
    console.log("[OMC] Plugin not found. Run: /oh-my-claudecode:omc-setup");
  }
}

main();

Step 3: Make it executable:

chmod +x ~/.claude/hud/omc-hud.mjs

Step 4: Update settings.json to use the HUD:

Read ~/.claude/settings.json, then update/add the statusLine field.

IMPORTANT: The command must use an absolute path, not ~, because Windows does not expand ~ in shell commands.

First, determine the correct path:

node -e "const p=require('path').join(require('os').homedir(),'.claude','hud','omc-hud.mjs');console.log(JSON.stringify(p))"

Then set the statusLine field using the resolved path. On Unix it will look like:

{
  "statusLine": {
    "type": "command",
    "command": "node /home/username/.claude/hud/omc-hud.mjs"
  }
}

On Windows it will look like:

{
  "statusLine": {
    "type": "command",
    "command": "node C:\\Users\\username\\.claude\\hud\\omc-hud.mjs"
  }
}

Use the Edit tool to add/update this field while preserving other settings.

Step 5: Clean up old HUD scripts (if any):

rm -f ~/.claude/hud/sisyphus-hud.mjs 2>/dev/null

Step 6: Tell the user to restart Claude Code for changes to take effect.

Display Presets

Minimal

Shows only the essentials:

[OMC] ralph | ultrawork | todos:2/5

Focused (Default)

Shows all relevant elements:

[OMC] ralph:3/10 | US-002 | ultrawork skill:planner | ctx:67% | agents:2 | bg:3/5 | todos:2/5

Full

Shows everything including multi-line agent details:

[OMC] ralph:3/10 | US-002 (2/5) | ultrawork | ctx:[████░░]67% | agents:3 | bg:3/5 | todos:2/5
├─ O architect    2m   analyzing architecture patterns...
├─ e explore     45s   searching for test files
└─ s executor     1m   implementing validation logic

Multi-Line Agent Display

When agents are running, the HUD shows detailed information on separate lines:
- Tree characters (├─, └─) show visual hierarchy
- Agent code (O, e, s) indicates agent type with model tier color
- Duration shows how long each agent has been running
- Description shows what each agent is doing (up to 45 chars)

Display Elements

Color Coding

• Green: Normal/healthy
• Yellow: Warning (context >70%, ralph >7)
• Red: Critical (context >85%, ralph at max)

Configuration Location

HUD config is stored at: ~/.claude/.omc/hud-config.json

Manual Configuration

You can manually edit the config file:

{
  "preset": "focused",
  "elements": {
    "omcLabel": true,
    "ralph": true,
    "prdStory": true,
    "activeSkills": true,
    "lastSkill": true,
    "contextBar": true,
    "agents": true,
    "backgroundTasks": true,
    "todos": true,
    "showCache": true,
    "showCost": true
  },
  "thresholds": {
    "contextWarning": 70,
    "contextCritical": 85,
    "ralphWarning": 7
  }
}

Troubleshooting

If the HUD is not showing:
1. Run /oh-my-claudecode:hud setup to auto-install and configure
2. Restart Claude Code after setup completes
3. If still not working, run /oh-my-claudecode:doctor for full diagnostics

Manual verification:
- HUD script: ~/.claude/hud/omc-hud.mjs
- Settings: ~/.claude/settings.json should have statusLine configured

The HUD updates automatically every ~300ms during active sessions.
