HUD Skill

The OMX HUD uses a two-layer architecture:

1. Layer 1 - Codex built-in statusLine: Real-time TUI footer showing model, git branch, and context usage. Configured via [tui] status_line in ~/.codex/config.toml. Zero code required.

2. Layer 2 - omx hud CLI command: Shows runtime orchestration state and turns. Legacy names in its output identify existing records for inspection, not workflows to activate.

Use Layer 2 only on a supported attached OMX CLI surface. In Codex App outside tmux, inspect supported native status/configuration instead of launching or fabricating a HUD.

Quick Commands

Command	Description
omx hud	Show current HUD (modes, turns, activity)
omx hud --watch	Live-updating display (polls every 1s)
omx hud --json	Raw state output for scripting
omx hud --preset=minimal	Minimal display
omx hud --preset=focused	Default display
omx hud --preset=full	All elements

Presets

minimal

[OMX] ralph:3/10 | turns:42

focused (default)

[OMX] ralph:3/10 | ultrawork | team:3 workers | turns:42 | last:5s ago

full

[OMX] ralph:3/10 | ultrawork | autopilot:execution | team:3 workers | pipeline:exec | turns:42 | last:5s ago | total-turns:156

Setup

omx setup automatically configures both layers:

• Adds [tui] status_line to ~/.codex/config.toml (Layer 1)
• Writes .omx/hud-config.json with default preset (Layer 2)
• Default preset is focused; if HUD/statusline changes do not appear, restart Codex CLI once.

Layer 1: Codex Built-in StatusLine

Configured in ~/.codex/config.toml:

[tui]
status_line = ["model-with-reasoning", "git-branch", "context-remaining"]

Available built-in items (Codex CLI v0.101.0+): model-name, model-with-reasoning, current-dir, project-root, git-branch, context-remaining, context-used, five-hour-limit, weekly-limit, codex-version, context-window-size, used-tokens, total-input-tokens, total-output-tokens, session-id

Layer 2: OMX Orchestration HUD

The omx hud command reads these state files:

• .omx/state/ralph-state.json - Ralph loop iteration
• .omx/state/ultrawork-state.json - Ultrawork mode
• .omx/state/autopilot-state.json - Autopilot phase
• .omx/state/team-state.json - Team workers
• .omx/state/pipeline-state.json - Pipeline stage
• .omx/state/ecomode-state.json - Ecomode active
• .omx/state/hud-state.json - Last activity (from notify hook)
• .omx/metrics.json - Turn counts

Configuration

HUD config stored at .omx/hud-config.json:

{
  "preset": "focused"
}

Color Coding

• Green: Normal/healthy
• Yellow: Warning (ralph >70% of max)
• Red: Critical (ralph >90% of max)

Troubleshooting

If the TUI statusline is not showing:

1. Ensure Codex CLI v0.101.0+ is installed
2. Run omx setup to configure [tui] section
3. Restart Codex CLI

If omx hud shows "No active modes":

• This is expected when no workflows are running
• Do not start a workflow merely to populate the HUD; report the idle state.
