Diverga HUD Skill

Configure and manage the Diverga HUD (Heads-Up Display) statusline.

Overview

The Diverga HUD provides a real-time statusline in your terminal showing:

• Current research project name
• Research stage progress
• Checkpoint completion status
• Memory/context health

The HUD is **independent** of oh-my-claudecode and works as a standalone component.

Commands

Status

/diverga-hud status

Show current HUD configuration and status:

• Whether HUD is enabled
• Current preset
• Project name and stage
• Checkpoint progress
• Memory health

Presets

/diverga-hud preset <preset_name>

Change HUD display preset:

| Preset | Description | Example Output | |--------|-------------|----------------| | `research` | Standard view (default) | `🔬 AI-Ethics │ Stage: foundation │ ●●○○○ (2/11) │ 🧠 95%` | | `checkpoint` | Detailed checkpoints | Multi-line with checkpoint details | | `memory` | Memory focus | Shows context and memory health | | `minimal` | Stage only | `🔬 foundation` |

Enable/Disable

/diverga-hud enable
/diverga-hud disable

Turn HUD display on or off.

Setup

/diverga-hud setup

Install or repair HUD statusline integration: 1. Creates `~/.claude/hud/diverga-hud.mjs` 2. Updates `~/.claude/settings.json` with statusLine command 3. Initializes `.research/hud-state.json` in current project

Installation

Automatic (Recommended)

Run `/diverga-hud setup` to automatically configure HUD.

Manual

1. Ensure the HUD script exists at `~/.claude/hud/diverga-hud.mjs`

2. Add to `~/.claude/settings.json`:

{
  "statusLine": {
    "type": "command",
    "command": "node ~/.claude/hud/diverga-hud.mjs"
  }
}

3. Restart Claude Code for changes to take effect.

State Files

HUD State

**Location**: `.research/hud-state.json`

{
  "version": "1.0.0",
  "enabled": true,
  "preset": "research",
  "last_updated": "2026-02-04T18:45:00Z",
  "cache": {
    "project_name": "AI-Ethics-HR",
    "current_stage": "foundation",
    "checkpoints_completed": 2,
    "checkpoints_total": 11,
    "memory_health": 95
  }
}

Project State

HUD reads from:

• `.research/project-state.yaml` - Project metadata
• `.research/checkpoints.yaml` - Checkpoint completion status

Protocol

When `/diverga-hud` is invoked:

1. **status** command:

• Read `.research/hud-state.json`
• Display current configuration
• Show live project status

2. **preset** command:

• Validate preset name (research, checkpoint, memory, minimal)
• Update `.research/hud-state.json`
• Confirm change

3. **enable/disable** command:

• Update `.research/hud-state.json` enabled flag
• Confirm change

4. **setup** command:

• Check if `~/.claude/hud/` exists, create if not
• Copy/update `diverga-hud.mjs` script
• Update `~/.claude/settings.json` statusLine
• Initialize `.research/hud-state.json`
• Display success message

Error Handling

| Error | Response | |-------|----------| | No project found | "No Diverga project detected. Initialize with `/diverga-setup`" | | Invalid preset | "Invalid preset. Available: research, checkpoint, memory, minimal" | | Settings write fail | "Could not update settings.json. Check file permissions." |

HUD Components

Progress Bar

●●○○○○○○○○○ (2/11)

• `●` = Completed checkpoint (green)
• `○` = Pending checkpoint (dim)
• `(X/Y)` = Completed/Total count

Memory Health

🧠 95%

Color coding:

• Green: 70%+ (healthy)
• Yellow: 40-70% (moderate)
• Red: <40% (needs attention)

Stage Indicator

Available stages:

• `foundation` - Research question, paradigm
• `theory` - Theoretical framework
• `methodology` - Research design
• `design` - Database, sampling
• `execution` - Data collection, screening
• `analysis` - Data analysis
• `validation` - Quality, peer review

Examples

Check Status

User: /diverga-hud status

Claude: 📊 **Diverga HUD Status**

| Setting | Value |
|---------|-------|
| Enabled | ✅ Yes |
| Preset | research |
| Project | AI-Ethics-HR |
| Stage | foundation |
| Checkpoints | 2/11 (18%) |
| Memory Health | 95% |

HUD is active and displaying in statusline.

Change Preset

User: /diverga-hud preset minimal

Claude: ✅ HUD preset changed to **minimal**.

New display: `🔬 foundation`

To switch back: `/diverga-hud preset research`

Setup HUD

User: /diverga-hud setup

Claude: 🔧 **Setting up Diverga HUD...**

1. ✅ Created ~/.claude/hud/diverga-hud.mjs
2. ✅ Updated ~/.claude/settings.json
3. ✅ Initialized .research/hud-state.json

🎉 HUD setup complete!

**Please restart Claude Code** to activate the statusline.

Your HUD will display:
`🔬 AI-Ethics-HR │ Stage: foundation │ ●●○○○○○○○○○ (2/11) │ 🧠 95%`

Troubleshooting

HUD Not Showing

1. Check if script exists:

   ls -la ~/.claude/hud/diverga-hud.mjs

2. Check settings.json:

   cat ~/.claude/settings.json | grep statusLine

3. Test script manually:

   node ~/.claude/hud/diverga-hud.mjs

4. Ensure you're in a Diverga project directory (has `.research/` folder)

Stale Data

Run refresh to update cache:

/diverga-hud status

Or manually trigger cache rebuild by editing `.research/hud-state.json`.

Integration with Diverga

The HUD automatically updates when:

• Checkpoints are completed
• Stage advances
• Project state changes

For manual sync, use `/diverga-memory sync`.
