In plain words
What is it for?

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

shopify-theme-builder 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 3d 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

Shopify Theme Builder (Cursor rule)

When the task involves building or designing a Shopify theme, follow the workflow in this repo. It is agent-agnostic and self-contained.

  • Read AGENTS.md (or SKILL.md) for the full workflow, phase gates, and the design-token vocabulary. Start there.
  • Open references/*.md only when the relevant phase needs them (progressive disclosure). Copy assets/theme-skeleton/ as the scaffold base and pattern-match every new section against examples/section-hero.liquid.

Three hard constraints you must not trade away:

  1. Shopify-compliant — valid {% schema %} on every section, theme-check clean, no deprecated Liquid, mirror Dawn when unsure.
  2. 100% theme-editor controllable — no hard-coded text/color/font/image/ layout; every value is a setting, block, or section group.
  3. Systemized — one token layer (settings_schema.json → CSS custom properties); sections read var(--token) only.

Phases (gated): 0 discovery interview (blocking) → 1 architecture plan (approval) → 2 scaffold → 3 build sections → 4 design pass → 5 i18n & RTL → 6 QA (shopify theme check + scripts/validate_theme.py + references/qa-checklist.md) → 7 package. Do not skip the interview; do not cross a gate early.

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.
