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 | $0.00047 | $0.03052 |
| Opus 5 | $0.00023 | $0.01526 |
| Sonnet 5 | $0.00009 | $0.00610 |
| Haiku 4.5 | $0.00005 | $0.00305 |
Grade B, and why
ascii-art scanned grade B with 2 findings 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 10d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
### Usage (via terminal curl) This is a copy
97% identical to ascii-art — 17 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.

ASCII Art Skill
Multiple tools for different ASCII art needs. All tools are local CLI programs or free REST APIs — no API keys required.
Tool 1: Text Banners (pyfiglet — local)
Render text as large ASCII art banners. 571 built-in fonts.
Setup
pip install pyfiglet --break-system-packages -q
Usage
python3 -m pyfiglet "YOUR TEXT" -f slant
python3 -m pyfiglet "TEXT" -f doom -w 80 # Set width
python3 -m pyfiglet --list_fonts # List all 571 fonts
Recommended fonts
| Style | Font | Best for |
|---|---|---|
| Clean & modern | slant |
Project names, headers |
| Bold & blocky | doom |
Titles, logos |
| Big & readable | big |
Banners |
| Classic banner | banner3 |
Wide displays |
| Compact | small |
Subtitles |
| Cyberpunk | cyberlarge |
Tech themes |
| 3D effect | 3-d |
Splash screens |
| Gothic | gothic |
Dramatic text |
Tips
- Preview 2-3 fonts and let the user pick their favorite
- Short text (1-8 chars) works best with detailed fonts like
doomorblock - Long text works better with compact fonts like
smallormini
Tool 2: Text Banners (asciified API — remote, no install)
Free REST API that converts text to ASCII art. 250+ FIGlet fonts. Returns plain text directly — no parsing needed. Use this when pyfiglet is not installed or as a quick alternative.
Usage (via terminal curl)
# Basic text banner (default font)
curl -s "https://asciified.thelicato.io/api/v2/ascii?text=Hello+World"
# With a specific font
curl -s "https://asciified.thelicato.io/api/v2/ascii?text=Hello&font=Slant"
curl -s "https://asciified.thelicato.io/api/v2/ascii?text=Hello&font=Doom"
curl -s "https://asciified.thelicato.io/api/v2/ascii?text=Hello&font=Star+Wars"
curl -s "https://asciified.thelicato.io/api/v2/ascii?text=Hello&font=3-D"
curl -s "https://asciified.thelicato.io/api/v2/ascii?text=Hello&font=Banner3"
# List all available fonts (returns JSON array)
curl -s "https://asciified.thelicato.io/api/v2/fonts"
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.

ascii-art is a skill published in the GitHub repository math-inc/OpenGauss (1,260 stars, last pushed 5mo ago), licensed MIT. It adds 47 tokens to every session and 3,052 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). It is 97% identical to ascii-art, differing in 17 lines, and is treated as a copy.
