HUD Skill

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

Note: All ~/.claude/... paths in this guide respect CLAUDE_CONFIG_DIR when that environment variable is set.

Quick Commands

Command Description
/oh-my-claudecode:hud Show current HUD status (auto-setup if needed)
/oh-my-claudecode:hud setup Install/repair HUD statusline
/oh-my-claudecode:hud minimal Switch to minimal display
/oh-my-claudecode:hud focused Switch to focused display (default)
/oh-my-claudecode:hud full Switch to full display
/oh-my-claudecode:hud status Show detailed HUD status

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:

node -e "const p=require('path'),f=require('fs'),d=process.env.CLAUDE_CONFIG_DIR||p.join(require('os').homedir(),'.claude');console.log(f.existsSync(p.join(d,'hud','omc-hud.mjs'))?'EXISTS':'MISSING')"

Step 2: Verify the plugin is installed:

node -e "const p=require('path'),f=require('fs'),d=process.env.CLAUDE_CONFIG_DIR||p.join(require('os').homedir(),'.claude'),b=p.join(d,'plugins','cache','omc','oh-my-claudecode');try{const v=f.readdirSync(b).filter(x=>/^\d/.test(x)).sort((a,c)=>a.localeCompare(c,void 0,{numeric:true}));if(v.length===0){console.log('Plugin not installed - run: /plugin install oh-my-claudecode');process.exit()}const l=v[v.length-1],h=p.join(b,l,'dist','hud','index.js');console.log('Version:',l);console.log(f.existsSync(h)?'READY':'NOT_FOUND - try reinstalling: /plugin install oh-my-claudecode')}catch{console.log('Plugin not installed - run: /plugin install oh-my-claudecode')}"

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

First, create the directory:

node -e "require('fs').mkdirSync(require('path').join(process.env.CLAUDE_CONFIG_DIR||require('path').join(require('os').homedir(),'.claude'),'hud'),{recursive:true})"

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 dev paths, plugin cache, or npm package
 */

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

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

  // 1. Development paths (only when OMC_DEV=1)
  if (process.env.OMC_DEV === "1") {
    const devPaths = [
      join(home, "Workspace/oh-my-claudecode/dist/hud/index.js"),
      join(home, "workspace/oh-my-claudecode/dist/hud/index.js"),
      join(home, "projects/oh-my-claudecode/dist/hud/index.js"),
    ];

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

  // 2. Plugin cache (for production installs)
  // Respect CLAUDE_CONFIG_DIR so installs under a custom config dir are found
  const configDir = process.env.CLAUDE_CONFIG_DIR || join(home, ".claude");
  const pluginCacheBase = join(configDir, "plugins", "cache", "omc", "oh-my-claudecode");
  if (existsSync(pluginCacheBase)) {
    try {
      const versions = readdirSync(pluginCacheBase);
      if (versions.length > 0) {
        // Filter to only versions with built dist/hud/index.js
        // This prevents picking an unbuilt new version after plugin update
        const builtVersions = versions.filter(version => {
          const pluginPath = join(pluginCacheBase, version, "dist/hud/index.js");
          return existsSync(pluginPath);
        });

        if (builtVersions.length > 0) {
          const latestVersion = builtVersions.sort((a, b) => a.localeCompare(b, undefined, { numeric: true })).reverse()[0];
          pluginCacheVersion = latestVersion;
          pluginCacheDir = join(pluginCacheBase, latestVersion);
          const pluginPath = join(pluginCacheDir, "dist/hud/index.js");
          await import(pathToFileURL(pluginPath).href);
          return;
        }
      }
    } catch { /* continue */ }
  }

  // 3. npm package (global or local install)
  try {
    await import("oh-my-claudecode/dist/hud/index.js");
    return;
  } catch { /* continue */ }

  // 4. Fallback: provide detailed error message with fix instructions
  if (pluginCacheDir && existsSync(pluginCacheDir)) {
    // Plugin exists but dist/ folder is missing - needs build
    const distDir = join(pluginCacheDir, "dist");
    if (!existsSync(distDir)) {
      console.log(`[OMC HUD] Plugin installed but not built. Run: cd "${pluginCacheDir}" && npm install && npm run build`);
    } else {
      console.log(`[OMC HUD] Plugin dist/ exists but HUD not found. Run: cd "${pluginCacheDir}" && npm run build`);
    }
  } else if (existsSync(pluginCacheBase)) {
    // Plugin cache directory exists but no built versions found
    console.log("[OMC HUD] Plugin cache found but no built versions. Run: /oh-my-claudecode:omc-setup");
  } else {
    // No plugin installation found at all
    console.log("[OMC HUD] Plugin not installed. Run: /oh-my-claudecode:omc-setup");
  }
}

main();

Step 3: Make it executable (Unix only, skip on Windows):

node -e "if(process.platform==='win32'){console.log('Skipped (Windows)')}else{require('fs').chmodSync(require('path').join(process.env.CLAUDE_CONFIG_DIR||require('path').join(require('os').homedir(),'.claude'),'hud','omc-hud.mjs'),0o755);console.log('Done')}"

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

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

IMPORTANT: Do not use ~ in the command. On Unix, use $HOME to keep the path portable across machines. On Windows, use an absolute path because Windows does not expand ~ in shell commands.

If you are on Windows, first determine the correct path:

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

IMPORTANT: The command path MUST use forward slashes on all platforms. Claude Code executes statusLine commands via bash, which interprets backslashes as escape characters and breaks the path.

Then set the statusLine field. On Unix it should stay portable and look like:

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

On Windows the path uses forward slashes (not backslashes):

{
  "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):

node -e "const p=require('path'),f=require('fs'),d=process.env.CLAUDE_CONFIG_DIR||p.join(require('os').homedir(),'.claude'),t=p.join(d,'hud','omc-hud.mjs');try{if(f.existsSync(t)){f.unlinkSync(t);console.log('Removed legacy script')}else{console.log('No legacy script found')}}catch{}"

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] branch:main | 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] repo:oh-my-claudecode branch:main | ralph:3/10 | US-002 (2/5) | ultrawork | ctx:[████░░]67% | agents:3 | bg:3/5 | todos:2/5

├─ 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

Element Description
[OMC] Mode identifier
repo:name Git repository name (cyan)
branch:name Git branch name (cyan)
ralph:3/10 Ralph loop iteration/max
US-002 Current PRD story ID
ultrawork Active mode badge
skill:name Last activated skill (cyan)
ctx:67% Context window usage
agents:2 Running subagent count
bg:3/5 Background task slots
todos:2/5 Todo completion

Color Coding

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

Configuration Location

HUD config is stored in ~/.claude/settings.json under the omcHud key (or your custom config directory if CLAUDE_CONFIG_DIR is set).

Legacy config location (deprecated): ~/.claude/.omc/hud-config.json

Manual Configuration

You can manually edit the config file. Each option can be set individually - any unset values will use defaults.

{
  "preset": "focused",

  },
  "staleTaskThresholdMinutes": 30,
  "contextLimitWarning": {
    "threshold": 80,
    "autoCompact": false
  }
}

safeMode

When safeMode is true (default), the HUD strips ANSI codes and uses ASCII-only output to prevent terminal rendering corruption during concurrent updates. This is especially important on Windows and when using terminal multiplexers.

agentsFormat Options

  • count: agents:2
  • codes: agents:Oes (type-coded with model tier casing)
  • codes-duration: agents:O(2m)es (codes with duration)
  • detailed: agents:[architect(2m),explore,exec]
  • descriptions: O:analyzing code | e:searching (codes + what they're doing)
  • tasks: [analyzing code, searching...] (just descriptions)
  • multiline: Multi-line display with full agent details on separate lines

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:omc-doctor for full diagnostics

Legacy string format migration: Older OMC versions wrote statusLine as a plain string (e.g., "~/.claude/hud/omc-hud.mjs"). Modern Claude Code (v2.1+) requires an object format. Running the installer or /oh-my-claudecode:hud setup will auto-migrate legacy strings to the correct object format:

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

Node 24+ compatibility: The HUD wrapper script imports homedir from node:os (not node:path). If you encounter SyntaxError: The requested module 'path' does not provide an export named 'homedir', re-run the installer to regenerate omc-hud.mjs.

Manual verification:

  • HUD script: ~/.claude/hud/omc-hud.mjs
  • Settings: ~/.claude/settings.json should have statusLine configured as an object with type and command fields

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