Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

diagram-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 12d 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.

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 doom or block
  • Long text works better with compact fonts like small or mini

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"

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.
