Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

unslop-ui 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.

What it actually says

Un-slop the UI

AI-built UIs are "recognizable on sight" — a homogeneous look from a handful of default choices. Before finishing UI work, remove these tells. Run yoke design-scan . for the statically detectable ones, then apply judgement for the structural ones the scanner can't see.

The ranked tells (and the fix)

  • AI-purple gradients (the #1 tell) — purple/violet gradients and #6c5ce7-family accents. → Choose one real brand color with intent; avoid purple-by-default.
  • Gradient hero textbg-clip-text text-transparent rainbow headings. → Solid color + type weight/scale for emphasis.
  • Neon glow0 0 Npx colored box-shadows / shadow-[0_0_...]. → Subtle, neutral elevation (small offset, low blur, low opacity).
  • Emoji-as-icons — 🚀✨🔥 in buttons/nav/feature lists. → A real icon set (lucide, etc.), consistent stroke + size.
  • Untouched shadcn/Tailwind defaults — default radius, default slate everywhere. → Set deliberate tokens (radius, spacing scale, one accent) so it doesn't look boilerplate.
  • Centered hero + three feature cards — the canonical AI landing layout. → Vary rhythm: asymmetry, a real product shot, content density that fits the product.
  • Homogeneous spacing / no hierarchy — everything the same size and gap. → Establish a type scale and spacing rhythm; make the primary action obviously primary.

Rule

Treat yoke design-scan . as a gate (it exits non-zero over budget). Fix findings, then eyeball the structural tells above. Distinctive, intentional > generic-but-safe.

Rubric informed by the MIT-licensed research in vibecoded-design-tells (© Carter Johnson). Yoke implements the idea natively; no code/data copied.

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.
