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 | $0.00020 | $0.00262 |
| Opus 5 | $0.00010 | $0.00131 |
| Sonnet 5 | $0.00004 | $0.00052 |
| Haiku 4.5 | $0.00002 | $0.00026 |
Grade A, and why
frontend-design 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 yesterday.
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.
This is a copy
98% identical to frontend-design — 50 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Frontend Design
Build working interfaces with a visual direction grounded in the user's purpose, audience, and existing brand. Choose one coherent direction and carry it through composition, typography, color, imagery, and interaction. Preserve a supplied design or established system unless the requested change includes redesigning it.
Focus effort where it changes the experience: clear hierarchy, useful density, readable copy, recognizable actions, and responsive composition. Distinctive fonts, asymmetry, texture, and motion are tools, not universal requirements. Check available assets and dependencies instead of assuming a font or animation package exists.
Implement real behavior and the relevant loading, empty, error, disabled, and success states. Keep semantic structure, keyboard access, focus visibility, contrast, and text scaling. Support reduced motion and keep essential content usable if animation fails. Label mock data; never invent testimonials or product claims as facts.
Match complexity to the brief. Reuse project tokens and components, and split cohesive responsibilities according to repository limits. Inspect the result at relevant sizes and fix material visual or interaction defects before reporting completion.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

frontend-design is a skill published in the GitHub repository tutur3u/platform (53 stars, last pushed today), licensed Apache-2.0. It adds 20 tokens to every session and 262 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 98% identical to frontend-design, differing in 50 lines, and is treated as a copy.
