# HUD Skill

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

## Quick Commands

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

## Auto-Setup

When you run `/hud` or `/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:
```bash
ls ~/.claude/hud/omc-hud.mjs 2>/dev/null && echo "EXISTS" || echo "MISSING"
```

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

**If NOT_BUILT**, the plugin needs to be compiled. Run:
```bash
cd ~/.claude/plugins/cache/omc/oh-my-claudecode/$PLUGIN_VERSION && npm install
```
This will install dependencies and build the TypeScript code automatically (via the `prepare` script).

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

First, create the directory:
```bash
mkdir -p ~/.claude/hud
```

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

```javascript
#!/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";

async function main() {
  const home = homedir();

  // 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().reverse()[0];
        const pluginPath = join(pluginCacheBase, latestVersion, "dist/hud/index.js");
        if (existsSync(pluginPath)) {
          await import(pluginPath);
          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(devPath);
        return;
      } catch { /* continue */ }
    }
  }

  // 3. Fallback
  console.log("[OMC] run /omc-setup to install properly");
}

main();
```

**Step 3:** Make it executable:
```bash
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:
```json
{
  "statusLine": {
    "type": "command",
    "command": "node ~/.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):
```bash
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

| Element | Description |
|---------|-------------|
| `[OMC]` | Mode identifier |
| `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 at: `~/.claude/.omc/hud-config.json`

## Manual Configuration

You can manually edit the config file:

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

## Troubleshooting

If the HUD is not showing:
1. Run `/hud setup` to auto-install and configure
2. Restart Claude Code after setup completes
3. If still not working, run `/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.*
