OpenGauss is a project-scoped Lean workflow orchestrator that gives coding agents a command-line interface for managing formal proof and formalization tasks. It is used with Lean projects to coordinate agents, tooling, backend sessions, and workflows supplied by lean4-skills. The catalogue add-ons operate these Gauss-native workflows.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.00737 |
| Opus 5 | $0.00017 | $0.00368 |
| Sonnet 5 | $0.00007 | $0.00147 |
| Haiku 4.5 | $0.00003 | $0.00074 |
Grade A, and why
openhue scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

91% identical to openhue — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenHue CLI
Control Philips Hue lights and scenes via a Hue Bridge from the terminal.
Prerequisites
# Linux (pre-built binary)
curl -sL https://github.com/openhue/openhue-cli/releases/latest/download/openhue-linux-amd64 -o ~/.local/bin/openhue && chmod +x ~/.local/bin/openhue
# macOS
brew install openhue/cli/openhue-cli
First run requires pressing the button on your Hue Bridge to pair. The bridge must be on the same local network.
When to Use
- "Turn on/off the lights"
- "Dim the living room lights"
- "Set a scene" or "movie mode"
- Controlling specific Hue rooms, zones, or individual bulbs
- Adjusting brightness, color, or color temperature
Common Commands
List Resources
openhue get light # List all lights
openhue get room # List all rooms
openhue get scene # List all scenes
Control Lights
# Turn on/off
openhue set light "Bedroom Lamp" --on
openhue set light "Bedroom Lamp" --off
# Brightness (0-100)
openhue set light "Bedroom Lamp" --on --brightness 50
# Color temperature (warm to cool: 153-500 mirek)
openhue set light "Bedroom Lamp" --on --temperature 300
# Color (by name or hex)
openhue set light "Bedroom Lamp" --on --color red
openhue set light "Bedroom Lamp" --on --rgb "#FF5500"
Control Rooms
# Turn off entire room
openhue set room "Bedroom" --off
# Set room brightness
openhue set room "Bedroom" --on --brightness 30
Scenes
openhue set scene "Relax" --room "Bedroom"
openhue set scene "Concentrate" --room "Office"
Quick Presets
# Bedtime (dim warm)
openhue set room "Bedroom" --on --brightness 20 --temperature 450
# Work mode (bright cool)
openhue set room "Office" --on --brightness 100 --temperature 250
# Movie mode (dim)
openhue set room "Living Room" --on --brightness 10
# Everything off
openhue set room "Bedroom" --off
openhue set room "Office" --off
openhue set room "Living Room" --off
Notes
- Bridge must be on the same local network as the machine running Gauss
- First run requires physically pressing the button on the Hue Bridge to authorize
- Colors only work on color-capable bulbs (not white-only models)
- Light and room names are case-sensitive — use
openhue get lightto check exact names - Works great with cron jobs for scheduled lighting (e.g. dim at bedtime, bright at wake)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

openhue is a skill published in the GitHub repository math-inc/OpenGauss (1,260 stars, last pushed 5mo ago), licensed MIT. It adds 35 tokens to every session and 737 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 91% identical to openhue, differing in 16 lines, and is treated as a copy.
