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 | $0.00165 | $0.00165 |
| Opus 5 | $0.00082 | $0.00082 |
| Sonnet 5 | $0.00033 | $0.00033 |
| Haiku 4.5 | $0.00016 | $0.00016 |
Grade A, and why
superui CLAUDE.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 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.
What it actually says
SuperUI for Claude
Use SuperUI when the task involves frontend UI creation, redesign, analysis, DESIGN.md, planning, implementation, responsive behavior, accessibility, or review.
Hard trigger: when the user explicitly says SuperUI, superui, $superui, this skill, use this skill, call SuperUI, or use SuperUI, load skills/superui/SKILL.md before answering.
Primary skill entry:
skills/superui/SKILL.md
The skill suite is platform-neutral. Claude should start from skills/superui/SKILL.md and let SuperUI route to child skills and shared references by need.
Do not eagerly load every file under skills/superui-shared/; those references are intentionally progressive.
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.

superui CLAUDE.md is an instructions file published in the GitHub repository HappyDoggyAI/superui (2 stars, last pushed 2mo ago), licensed MIT. It adds 165 tokens to every session, about $0.0008 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 2026-08-31.
