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 | $0.00530 |
| Opus 5 | $0.00032 | $0.00265 |
| Sonnet 5 | $0.00013 | $0.00106 |
| Haiku 4.5 | $0.00006 | $0.00053 |
Grade A, and why
aibvf-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 10d 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
Read the README.md file within this skill, and explore the other available files. If creating visual artifacts (slides, mocks, throwaway prototypes, etc), copy assets out and create static HTML files for the user to view. If working on production code, you can copy assets and read the rules here to become an expert in designing with this brand. If the user invokes this skill without any other guidance, ask them what they want to build or design, ask some questions, and act as an expert designer who outputs HTML artifacts or production code, depending on the need.
Quick orientation
- One accent (copper
#B87333) on deep navy (#0F1E35). No other decorative colour. RAG (green/amber/red) is functional signal only — Accelerate / Fix / Stop. - Type: Playfair Display (serif — headings, KPI values, quotes; upright, no italics), DM Sans (body/UI), IBM Plex Mono (EUR figures, scores).
- Themes: dark navy by default; add
data-theme="light"to<html>for the warm-ivory light theme. Same copper accent both ways. - Tone: executive/advisory, measured, "holds up the mirror." No emoji, no hype. See README → Content Fundamentals.

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.

aibvf-design is a skill published in the GitHub repository Craig-Horton/ai-bvf (0 stars, last pushed 8d ago), licensed MIT. It adds 64 tokens to every session and 530 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 2026-08-31.
