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 | $0.00077 | $0.04167 |
| Opus 5 | $0.00039 | $0.02083 |
| Sonnet 5 | $0.00015 | $0.00833 |
| Haiku 4.5 | $0.00008 | $0.00417 |
Grade A, and why
shopify-liquid-kona-standards scanned grade A with 1 finding 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 12d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

CSS, JS & HTML Standards
Core Principles
- Progressive enhancement — semantic HTML first, CSS second, JS third
- Tailwind utility-first — use utility classes directly in markup; extract to
@applyonly when reused - Island hydration — zero JS by default; interactive components hydrate on demand
- Design tokens — all values flow through Tailwind's
@themeblock or CSS custom properties - No external JS dependencies — native browser APIs only
CSS Architecture
Where CSS Lives
| Location | Purpose |
|---|---|
theme/frontend/styles/theme.css |
@theme block — design tokens (colors, spacing, fonts) |
theme/frontend/styles/base.css |
@layer base — element resets and global styles |
theme/frontend/styles/components.css |
@layer components — reusable component classes via @apply |
theme/frontend/styles/utilities.css |
@layer utilities — custom utility classes |
theme/frontend/entrypoints/theme.css |
Entry point — imports all layers (don't add styles here) |
Inline class="" in Liquid |
Primary styling method — Tailwind utility classes |
{% style %} in Liquid |
Dynamic CSS needing Liquid values (section settings) |
No {% stylesheet %} tags — this theme uses Vite + Tailwind, not Shopify's built-in bundling.
Tailwind Utility-First Approach

What ships with it
2 files 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.
