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 | $0.00038 | $0.01704 |
| Opus 5 | $0.00019 | $0.00852 |
| Sonnet 5 | $0.00008 | $0.00341 |
| Haiku 4.5 | $0.00004 | $0.00170 |
Grade A, and why
shopify-admin-email-deliverability-audit 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Scans the entire customer list and flags addresses that will hurt email deliverability if included in marketing sends: syntactically invalid addresses, role accounts (info@, admin@, sales@), known disposable / temporary domains, and suspected hard-bounce patterns. Output is a suppression list ready to import into your email platform. Read-only — no mutations.
Prerequisites
- Authenticated Shopify CLI session:
shopify store auth --store <domain> --scopes read_customers - API scopes:
read_customers
Parameters
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
| store | string | yes | — | Store domain (e.g., mystore.myshopify.com) |
| marketing_consent_only | bool | no | true | Only scan customers who currently accept marketing — those are the ones at risk of being mailed |
| disposable_domains | array | no | built-in list | Override built-in disposable-domain list |
| role_localparts | array | no | ["info","admin","sales","support","contact","noreply","help","webmaster","postmaster"] |
Local-part prefixes to flag as role accounts |
| format | string | no | human | Output format: human or json |
Safety
ℹ️ Read-only skill — no mutations are executed. Safe to run at any time. No emails are sent, no marketing consent is changed.
Detection Rules
For each customer email, run these checks in order and assign one or more flags:
invalid_syntax— fails RFC 5322 local-part / domain validation, missing@, contains whitespace, double dots, leading/trailing dotrole_account— local part exactly matches arole_localpartsentry (case-insensitive)disposable_domain— domain matches the disposable-domain list (mailinator, guerrillamail, tempmail-style domains, etc.)plus_alias— contains+in local part (informational; not a deliverability problem on its own, but useful for de-duplication)bounce_suspect— heuristics: numeric-only local part, length > 64 chars, ALL-CAPS, repeated characters (aaaaa), keyboard rolls (asdfghjk)duplicate— same normalized email already seen in the customer set
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.
