Hermes Agent is an AI assistant that learns from its use by creating and improving skills, retaining knowledge, searching past conversations, and adapting to its users. It is for people who want to run an agent through a terminal or messaging platforms while connecting it to different AI models and scheduled tasks.
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.

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 | $0.00015 | $0.03915 |
| Opus 5 | $0.00008 | $0.01958 |
| Sonnet 5 | $0.00003 | $0.00783 |
| Haiku 4.5 | $0.00002 | $0.00392 |
Grade A, and why
shopify 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 2d 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.

How it starts
The opening of the file, as written. The whole thing — 374 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shopify — Admin & Storefront GraphQL APIs
Work with Shopify stores directly through curl: list products, manage inventory, pull orders, update customers, read metafields. No SDK, no app framework — just the GraphQL endpoint and a custom-app access token.
The REST Admin API is legacy since 2024-04 and only receives security fixes. Use GraphQL Admin for all admin work. Use Storefront GraphQL for read-only customer-facing queries (products, collections, cart).
Prerequisites
- In Shopify admin: Settings → Apps and sales channels → Develop apps → Create an app.
- Click Configure Admin API scopes, select what you need (examples below), save.
- Install app → the Admin API access token appears ONCE. Copy it immediately — Shopify will never show it again. Tokens start with
shpat_. - Save to
${HERMES_HOME:-~/.hermes}/.env:SHOPIFY_ACCESS_TOKEN=shpat_xxxxxxxxxxxxxxxxxxxx SHOPIFY_STORE_DOMAIN=my-store.myshopify.com SHOPIFY_API_VERSION=2026-01
Heads up: As of January 1, 2026, new "legacy custom apps" created in the Shopify admin are gone. New setups should use the Dev Dashboard (
shopify.dev/docs/apps/build/dev-dashboard). Existing admin-created apps keep working. If the user's shop has no existing custom app and it's after 2026-01-01, direct them to Dev Dashboard instead of the admin flow.
Common scopes by task:
- Products / collections:
read_products,write_products - Inventory:
read_inventory,write_inventory,read_locations - Orders:
read_orders,write_orders(30 most recent withoutread_all_orders) - Customers:
read_customers,write_customers - Draft orders:
read_draft_orders,write_draft_orders - Fulfillments:
read_fulfillments,write_fulfillments - Metafields / metaobjects: covered by the matching resource scopes
API Basics
- Endpoint:
https://$SHOPIFY_STORE_DOMAIN/admin/api/$SHOPIFY_API_VERSION/graphql.json - Auth header:
X-Shopify-Access-Token: $SHOPIFY_ACCESS_TOKEN(NOTAuthorization: Bearer) - Method: always
POST, alwaysContent-Type: application/json, body is{"query": "...", "variables": {...}} - HTTP 200 does not mean success. GraphQL returns errors in a top-level
errorsarray and per-fielduserErrors. Always check both. - IDs are GID strings:
gid://shopify/Product/10079467700516,gid://shopify/Variant/...,gid://shopify/Order/.... Pass these verbatim — don't strip the prefix. - Rate limit: calculated via query cost (leaky bucket). Each response has
extensions.costwithrequestedQueryCost,actualQueryCost,throttleStatus.{currentlyAvailable, maximumAvailable, restoreRate}. Back off whencurrentlyAvailabledrops below your next query's cost. Standard shops = 100 points bucket, 50/s restore; Plus = 1000/100.
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.

shopify is a skill published in the GitHub repository NousResearch/hermes-agent (241,505 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 3,915 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
