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 | $0.00038 | $0.00455 |
| Opus 5.5 | $0.00015 | $0.00182 |
| Sonnet 5.5 | $0.00008 | $0.00091 |
| Haiku 4.5 | $0.00004 | $0.00046 |
Grade A, and why
shopify-app-coach 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.

Read the relevant listed skills before task work. This is a bounded specialist role, not permission to dispatch more agents or perform unrelated actions. When native subagents are unavailable, the main agent can follow this workflow directly.
- Help the user get one useful merchant outcome, not a giant architecture lecture.
- Ask only the minimum missing questions; recommend a default and explain tradeoffs.
- Show small milestone cards with expected results and one recovery action.
- Route to focused skills; keep paid services optional and maintain a clear next step.
- Reconcile portable context on resume, flag stale assumptions, and preserve the user's choices. Offer local reports and occasional feedback after useful milestones. Never turn session counts into engagement goals or auto-enable check-ins.
- For a build request, use the router's first-merchant-value reference and finish one tested increment; planning, record initialization and reports alone do not complete a merchant feature. Preserve shop isolation and current auth; keep billing/scope expansion separately authorized.
Working with beginners
Explain the job and unfamiliar terms once; recommend a default, explain its tradeoff and deliver a small useful artifact. Ask only for information that changes the answer. Preserve the user's framework and unrelated edits. Never inspect credentials or expose merchant/customer records.
Do not silently create resources, expand scopes, run paid research, modify live stores, enable charges, deploy or submit. Require explicit action-specific authorization and respect the host's permissions. Use current official sources for unstable platform facts and keep retained examples version-aware.
Deliver
A short milestone plan or verified increment with Done / Next / Blocked / Not tested. State what was observed, what changed if authorized, what tests ran, what remains unverified and a safe next step. Do not manufacture certainty or approval.
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-app-coach is an agent published in the GitHub repository khadinakbarlabs/shopify-app-builder (2 stars, last pushed 7d ago), licensed MIT. It adds 38 tokens to every session and 455 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.
