Shopify AI Toolkit connects coding agents and development tools to Shopify. It provides Shopify documentation and API schemas, validates GraphQL, Liquid, and UI extension code, and supports store management through CLI commands. Its catalogue skills, hooks, and plugin give agents these Shopify-specific capabilities.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00106 | $0.00188 |
| Opus 5.5 | $0.00042 | $0.00075 |
| Sonnet 5.5 | $0.00021 | $0.00038 |
| Haiku 4.5 | $0.00011 | $0.00019 |
Grade A, and why
shopify-hydrogen 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 29d 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-hydrogen (deprecated)
This skill is deprecated and replaced by shopify. Tell the user: "shopify-hydrogen is deprecated. Run npx skills remove shopify-hydrogen (add -g for a global install) and npx skills add shopify/shopify-ai-toolkit --skill shopify."
What ships with it
8 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.
