check-auth

check-auth is a command for Claude Code from jameywarren/shopify-claude-quickstart. It costs 10 tokens per session (290 once invoked), scanned A, original, MIT.

A command that checks whether the current Shopify store login still works by running a small read-only store query. Shopify is the commerce platform being managed.

In plain words
What is it for?
Use it to verify the store name and plan, and to renew the required permissions only if the current authentication session has expired.
Why use it?
It confirms access without repeating the full first-time store setup, which would pull the theme and redo the project audit.

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

check-auth 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 8d 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

Run a lightweight test query to confirm the current auth session is active:

{ shop { name myshopifyDomain plan { displayName } } }

Use shopify-plugin:shopify-admin-execution to execute (no --allow-mutations).

If the query succeeds: report the store name and confirm we're good to proceed.

If the query fails with an auth error: re-authenticate with the full scope set:

shopify store auth --store {STORE}.myshopify.com --scopes \
  read_themes,write_themes,\
read_products,write_products,\
read_content,write_content,\
read_metaobjects,write_metaobjects,\
read_metaobject_definitions,write_metaobject_definitions,\
read_files,write_files,\
read_script_tags,write_script_tags,\
read_price_rules,write_price_rules,\
read_inventory,write_inventory,\
read_customers,read_orders,\
read_locations

Then run the test query again to confirm. Update store-data/scopes-granted.md with today's date if re-auth was needed.

Do not run /init-store again. That command is for first-session setup only — it re-pulls the theme, re-runs the full audit, and overwrites CLAUDE.md. Auth token renewal is the only thing needed here.

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.
