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 | $0.00504 | $0.00504 |
| Opus 5.5 | $0.00202 | $0.00202 |
| Sonnet 5.5 | $0.00101 | $0.00101 |
| Haiku 4.5 | $0.00050 | $0.00050 |
Grade A, and why
design-system-generator-skill AGENTS.md 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.

Design System Generator — Agent Instructions
This file enables the Design System Generator skill for OpenAI Codex and similar agents.
https://github.com/XINGANLIU/design-system-generator-skill
Skill: Design System Generator
When the user asks to create a design system, generate a color palette, build a theme, create UI tokens, or set up brand styles, follow the workflow defined in:
Main instructions: skills/design-system-generator/SKILL.md
Quick Reference
This skill generates a complete, production-ready design system from a single brand color:
- Brand Input → Collect brand color (hex/rgb/oklch), font family, border radius style
- Color System → OKLCH palettes: primary (10 steps), neutral (10 steps), semantic (success/warning/error/info)
- Tokens → W3C Design Tokens JSON + CSS custom properties with Light/Dark theme support
- Components → Button, Card, Input, Badge, Alert, Avatar, Skeleton, Tooltip, Modal, Navbar, Divider
- Preview → Self-contained HTML preview page with theme toggle

Output Structure

├── tokens.json # W3C Design Tokens
├── tokens.css # CSS Custom Properties
├── components.css # Component styles
└── preview.html # Visual preview page
Key Constraints
- All colors MUST use OKLCH color space
- Components MUST only use
var(--token-name)— no hardcoded values - WCAG 2.2 AA contrast compliance required
- Support Light and Dark themes via
light-dark()+[data-theme] - Follow phases in order, confirm with user between phases
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.

design-system-generator-skill AGENTS.md is an instructions file published in the GitHub repository XINGANLIU/design-system-generator-skill (1 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 504 tokens to every session, about $0.0020 per session on Opus 5.5. A static security scan graded it A with 0 findings.
