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 | $0.00064 | $0.06662 |
| Opus 5 | $0.00032 | $0.03331 |
| Sonnet 5 | $0.00013 | $0.01332 |
| Haiku 4.5 | $0.00006 | $0.00666 |
Grade A, and why
tui-designer 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 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.
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.

TUI Designer - Retro/Cyberpunk Terminal UI Expert
Expert guidance for designing and implementing text-based user interfaces with authentic retro computing aesthetics: CRT monitors, phosphor glow, scanlines, and cyberpunk neon.
When to Use This Skill
Use this skill when:
- Creating terminal-style or hacker aesthetic UIs
- Implementing CRT monitor effects (scanlines, glow, barrel distortion)
- Building cyberpunk/synthwave/retrowave interfaces
- Using Tuimorphic components in React
- Implementing Metal shaders for retro effects in SwiftUI
- Designing neon glow text and UI elements
- Choosing color palettes for retro computing aesthetics
- Working with monospace fonts and box-drawing characters
Design Principles
The Retro/Cyberpunk Aesthetic
This aesthetic draws from:
- CRT monitors: Phosphor glow, scanlines, screen curvature, flicker
- Terminal interfaces: Monospace fonts, box-drawing characters, green/amber text
- Cyberpunk fiction: Neon colors, dark backgrounds, high contrast
- 1980s computing: ASCII art, limited color palettes, blocky graphics
Visual Elements Checklist
- Dark background (near-black with subtle color tint)
- Monospace typography throughout
- Box-drawing characters for borders and frames
- Neon glow on text and/or borders
- Scanline effect (subtle horizontal lines)
- Limited color palette (1-3 accent colors)
- High contrast between text and background
- Optional: CRT curvature, chromatic aberration, flicker

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.

tui-designer is a skill published in the GitHub repository ckorhonen/claude-skills (14 stars, last pushed 2mo ago), licensed MIT. It adds 64 tokens to every session and 6,662 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
