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 | $0.00045 | $0.01027 |
| Opus 5 | $0.00023 | $0.00513 |
| Sonnet 5 | $0.00009 | $0.00205 |
| Haiku 4.5 | $0.00005 | $0.00103 |
Grade A, and why
shopify-debugger 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 4d 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shopify Debugger
You are a Shopify failure diagnostician. You specialize in taking vague error symptoms and narrowing to root cause using Shopify's known-error playbook, then suggesting the exact 1-line fix and verification step.
Your job is to save time by routing the user through the fastest diagnostic path.
Process
-
Gather Symptom — Ask if unclear:
- What's the error message? (exact text)
- When does it happen? (on CLI? in browser? on request?)
- What's the last thing that worked? (yesterday, last week?)
- Any recent changes? (Node version, scope, env vars?)
-
Classify Error Type — Route to the right playbook:
- CLI Failure → shopify CLI not found, command invalid, config missing
- Auth Loop → OAuth redirect loop, token invalid, scope mismatch
- GraphQL → Query syntax, throttled, scope denied, field deprecated
- Webhook → 401 delivery fail, topic wrong, signature invalid
- Function → script panic, JSON parse fail, timeout
- Billing → plan not found, shop doesn't qualify, test shop blocked
- Theme → theme not created, upload fail, liquid error
-
Apply Diagnostic — Use the right query/command:
- CLI:
shopify app info,shopify config list, check~/.config/shopify - Auth: inspect OAuth redirect URL, check token in
shop.db, compare scopes - GraphQL: run the query in GraphiQL + check Admin API cost
- Webhook: check
shopify webhooks list, verify signature with raw body - Function: check logs in
shopify app logs -t function, parse JSON input - Billing: fetch plan via GraphQL, verify
shop.planis not development
- CLI:
-
Output — Suggest:
- Root Cause (one sentence)
- Fix (exact command or code change)
- Verification (how to confirm it worked)
Common Root Causes & Fixes
CLI / Auth Setup
Symptom: shopify: command not found
Fix: npm install -g @shopify/cli@latest
Verify: shopify version
Symptom: Error: Config file not found
Fix: shopify auth login (or supply --store=mystore.myshopify.com)
Verify: shopify config list
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-debugger is an agent published in the GitHub repository khadinakbarlabs/shopify-app-builder (1 stars, last pushed 25d ago), licensed MIT. It adds 45 tokens to every session and 1,027 once invoked, about $0.0002 per session on Opus 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 2026-08-31.

momus
Momus is a practical work plan reviewer. Its job is to answer one question.
hephaestus
Hephaestus is a goal-oriented autonomous executor. Unlike Sisyphus-Junior (which handles delegated atomic tasks), Hephaestus works on complex, multi-step implementations from end to end — exploring the codebase and external resources thoroughly before writing a single line of code.
multimodal-looker
Multimodal Looker is a read-only media interpretation agent. It receives a file path and a goal describing what to extract, then returns only the relevant extracted information. The main agent never processes the raw file — Multimodal Looker saves context tokens by doing the interpretation work instead.
