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 | $0.01112 | $0.01112 |
| Opus 5 | $0.00556 | $0.00556 |
| Sonnet 5 | $0.00222 | $0.00222 |
| Haiku 4.5 | $0.00111 | $0.00111 |
Grade A, and why
world-class-web-design-os 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
World-Class Web Design OS — Codex Operating Rules
These instructions apply to the entire repository.
Continuation handoff
When CODEX_HANDOFF.md exists, read it before substantive continuation work. It records inherited state, completed research/experiments, pending milestones, and non-negotiable decisions. Preserve that context unless the user explicitly changes direction.
Mission
Produce web experiences that are distinctive, coherent, usable, accessible, fast, and technically maintainable. Optimize for design intent and user outcomes rather than fashionable effects or component-library assembly.
Required routing
For any task that designs, redesigns, builds, or materially polishes a web page/interface, start with $web-design-orchestrator unless the user explicitly requests a narrower skill.
Use the specialist skills only when relevant:
$design-discovery— business goal, audience, CTQs, IA, content priority, CTA.$reference-forensics— visual reference decomposition and principled remixing.$art-direction— point of view, composition, typography, imagery, visual energy, signature concept.$design-system— tokens, primitives, component/state rules, responsive and motion tokens.$component-source-router— choose native/custom/primitives/component registries intentionally.$interaction-design— state, feedback, gestures, navigation, affordance, interaction budget.$motion-engine— select Motion, Anime.js, GSAP, Lenis, or native motion by intent.$creative-web— 3D, WebGL/WebGPU, Rive, Spline, Theatre.js, SVG/canvas/shaders.$frontend-implementation— semantic, maintainable production implementation.$responsive-recomposition— redesign priority and composition across breakpoints.$a11y-performance— accessibility and performance hard gates.$visual-qa— Playwright screenshots, regressions, overflow/state/browser checks.$design-critic— independent macro/meso/micro critique and Design Quality scoring.$ai-smell-detector— detect generic AI aesthetics and unjustified effects.$visual-polish— focused high-craft typography, spacing, imagery, surface and micro-interaction polish.$continuous-learning— convert defects and lessons into evidence-backed improvement proposals.
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.
