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 A, and why

ascii-art scanned grade A with 0 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

ASCII / Terminal Art

Local, keyless terminal art. Detect tools first: command -v figlet toilet lolcat chafa jp2a 2>/dev/null (Unix) / Get-Command figlet, chafa (Windows). Install: brew install figlet lolcat chafa jp2a / apt install figlet toilet lolcat chafa jp2a.

Big text banners

figlet "Deploy OK"
figlet -f slant "ChatCLI"          # other fonts: big, banner, standard
toilet -f mono12 -F metal "BUILD"  # toilet adds colors/filters

List figlet fonts: figlet -I2 shows the font directory; showfigfonts previews them.

Colorize

figlet "Done" | lolcat            # rainbow gradient

Image → ASCII / terminal preview

chafa image.png                   # high-fidelity terminal graphics (truecolor/sixel)
chafa --size 60x30 image.png
jp2a --colors image.jpg           # classic ASCII conversion

Rules

  • Banners are great for CLI/agent output; in messaging gateways (Telegram/WhatsApp), monospaced ASCII often breaks on phones — prefer plain text there, or send a rendered image.
  • Keep banners short; wide figlet output wraps badly in narrow terminals.
Changes

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.
