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 | $0.00042 | $0.00613 |
| Opus 5.5 | $0.00017 | $0.00245 |
| Sonnet 5.5 | $0.00008 | $0.00123 |
| Haiku 4.5 | $0.00004 | $0.00061 |
Grade A, and why
app-framework 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 25d 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 — 35 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build a foundation you can maintain
A framework supplies routing, rendering and Shopify integration. A database stores app-owned data; a background job processes work outside a page request.
Start here
For a new embedded app, follow the current official Shopify CLI scaffold and React Router integration, including current App Home/Polaris web component setup. Do not make a beginner choose a custom stack unless a concrete requirement needs it. For an existing app, inspect package versions, route layout, session storage, tests and hosting. Preserve a supported existing framework rather than forcing a migration.
Guided workflow
- Define one merchant task, inputs, output and failure states. Propose the smallest architecture with cost/maintenance tradeoffs.
- Use shopify-cli, app-auth, app-bridge and polaris-ui for the first authenticated embedded page.
- Model data ownership by shop, input validation, database constraints and query authorization. Every read/write must use the authenticated shop, not a client-supplied shop ID alone. Use parameterized access and avoid mass assignment.
- Add migrations and test fixtures; rehearse migrations with backup/recovery. Keep app configuration/secret injection separate from browser code and public source. Do not inspect local credentials to configure an app.
- Put slow syncs in durable jobs with deduplication, bounded retries, observable status and cleanup on uninstall. Authenticate callbacks; fail safely when dependencies are unavailable.
- Test before expanding features: unit rules, auth and shop-isolation integration tests, error handling and the primary end-to-end dev-store journey.
- Choose hosting only when needed; explain Shopify deploy manages configuration/extensions, while the app server/database need their own host. Obtain approval before provisioning or changing production.
Check it worked
A new merchant can install, reach first value, recover from an error and reopen saved state. A second shop cannot read the first shop's data. Tests cover denied/invalid requests, duplicate jobs and migration boundaries. Build/type checks and live dev-store QA are separate evidence.
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.

app-framework is a skill published in the GitHub repository khadinakbarlabs/shopify-app-builder (2 stars, last pushed 17d ago), licensed MIT. It adds 42 tokens to every session and 613 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-02.
