What it does

Shopify Advanced Troubleshooting is an agent skill from jeremylongshore/tons-of-skills-marketplace. Debug complex Shopify API issues using cost analysis, request tracing, webhook delivery inspection, and GraphQL introspection. Use when encountering intermittent failures, throttling mysteries, or webhook delivery gaps. Trigger with phrases like "shopify hard bug", "shopify mystery error", "shopify deep debug", "difficult shopify issue", "shopify intermittent failure".

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/debug-intermittent-failures.md`, `references/layer-by-layer-diagnostic.md` and `references/webhook-status-query.md`). Compatibility notes: Designed for Claude Code

It sits in Backend & APIs, covering Failing and flaky tests, Webhooks and GraphQL. It works with Shopify and GraphQL. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Encountering intermittent failures
  • Throttling mysteries
  • Webhook delivery gaps
  • With phrases like shopify hard bug

Example prompts

  • “shopify hard bug”
  • “shopify mystery error”
  • “shopify deep debug”
  • “/shopify-advanced-troubleshooting”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Grep, Bash(curl:*), Bash(node:*)

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. GraphQL Cost Analysis
  2. Trace a Specific Request
  3. Webhook Delivery Inspection
  4. GraphQL Introspection for API Version Differences
  5. Systematic Isolation
  6. Debug Intermittent Failures

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Grep
    • Bash(curl:*)
    • Bash(node:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • shopify.dev
    • help.shopify.com
    • community.shopify.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    From compatibility in the SKILL.md frontmatter.

Context cost

Shopify Advanced Troubleshooting loads about 1.3k tokens when it runs, and up to ~2.2k if it reads all its reference files. Until then it costs about 101 tokens; SKILL.md has 470 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~101
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Shopify Advanced Troubleshooting

Overview

Deep debugging for complex Shopify API issues: cost analysis with debug headers, webhook delivery inspection, GraphQL query introspection, and systematic isolation of intermittent failures.

Prerequisites

  • Access to Shopify admin and Partner Dashboard
  • Familiarity with GraphQL and HTTP debugging
  • curl and jq available

Instructions

Step 1: GraphQL Cost Analysis

When queries THROTTLE unexpectedly, use the cost debug header by adding Shopify-GraphQL-Cost-Debug: 1 to your request. The response extensions.cost reveals why a query is expensive.

Key: requestedQueryCost is first multiplied through nested connections. 50 products * 20 variants * (1 + 5 metafields) = high cost even if actual data is small.

Step 2: Trace a Specific Request

Every Shopify response includes X-Request-Id. Capture it for support escalation:

bash
curl -v -X POST "https://$STORE/admin/api/2025-04/graphql.json" \
  -H "X-Shopify-Access-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"query": "{ shop { name } }"}' 2>&1 | tee /tmp/shopify-debug.txt

grep -i "x-request-id" /tmp/shopify-debug.txt
Step 3: Webhook Delivery Inspection

Inspect webhook delivery status in the Partner Dashboard, or query subscription health via API.

See Webhook Status Query for the complete query and common delivery failure patterns.

Step 4: GraphQL Introspection for API Version Differences

Use introspection queries to check if specific fields or mutations exist in your API version. Query __type for field lists or __schema for available mutations filtered by prefix.

Step 5: Systematic Isolation

Run a layer-by-layer diagnostic that tests DNS, TCP, TLS, HTTP, GraphQL, and rate limit state independently.

See Layer-by-Layer Diagnostic for the complete shell script.

Step 6: Debug Intermittent Failures

Wrap Shopify calls in a debug logger that captures timing, cost, and error data for pattern analysis.

See Debug Intermittent Failures for the complete TypeScript implementation.

Output

  • Query cost breakdown identifying expensive fields
  • Request IDs captured for Shopify support
  • Webhook delivery health verified
  • Layer-by-layer isolation identifying failure point
  • Debug log with timing patterns for intermittent issues

Examples

Diagnosing Intermittent 502 Errors

A store experiences random 502 errors on product sync queries. Use the debug wrapper to capture timing and cost data across 100 requests, then analyze the pattern.

See Debug Intermittent Failures for the complete TypeScript implementation.

Isolating a Webhook Delivery Gap

Orders are created but the fulfillment webhook never fires. Run the webhook status query to check subscription health and delivery success rates.

See Webhook Status Query for the complete query and common delivery failure patterns.

Pinpointing a Network Layer Failure

API calls fail sporadically from a specific server. Run the layer-by-layer diagnostic to test DNS, TCP, TLS, HTTP, and GraphQL independently.

See Layer-by-Layer Diagnostic for the complete shell script.
