Load test Shopify integrations respecting API rate limits, plan capacity with k6, and scale for Shopify Plus burst events (flash sales, BFCM).

  • Works in 4 steps: Understand Capacity Constraints → k6 Load Test Script → Run Load Test → …
  • Preparing for high-traffic events
  • SKILL.md covers Overview, Prerequisites, Instructions and Output, plus 3 more sections
  • Calls curl, jq and brew; needs SHOPIFY_ACCESS_TOKEN

What it does

Shopify Load Scale is an agent skill from jeremylongshore/tons-of-skills-marketplace. Load test Shopify integrations respecting API rate limits, plan capacity with k6, and scale for Shopify Plus burst events (flash sales, BFCM). Use when preparing for high-traffic events, benchmarking API throughput, or sizing infrastructure for Shopify webhook volume. Trigger with phrases like "shopify load test", "shopify scale", "shopify BFCM", "shopify flash sale", "shopify capacity", "shopify k6 test".

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/bfcm-preparation.md` and `references/k6-load-test-script.md`). Compatibility notes: Designed for Claude Code

It sits in Backend & APIs, covering Load testing and Rate limiting. It works with Shopify. 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

  • Preparing for high-traffic events
  • Benchmarking API throughput
  • Sizing infrastructure for Shopify webhook volume
  • With phrases like shopify load test

Example prompts

  • “shopify load test”
  • “shopify scale”
  • “shopify BFCM”
  • “/shopify-load-scale”

Requirements

  • A credential in SHOPIFY_ACCESS_TOKEN
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(k6:*), Bash(curl:*)

Workflow steps

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

  1. Understand Capacity Constraints
  2. k6 Load Test Script
  3. Run Load Test
  4. BFCM / Flash Sale Preparation

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
    • Write
    • Edit
    • Bash(k6:*)
    • Bash(curl:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl
    • jq
    • brew

    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
    • k6.io
    • shopify.com

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SHOPIFY_ACCESS_TOKEN

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

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Shopify Load Scale loads about 1k tokens when it runs, and up to ~2.2k if it reads all its reference files. Until then it costs about 107 tokens; SKILL.md has 273 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~107
When it runs · the whole SKILL.md, loaded when a task matches
~1k
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 Load & Scale

Overview

Load test Shopify app integrations while respecting API rate limits. Plan capacity for high-traffic events like Black Friday / Cyber Monday (BFCM).

Prerequisites

  • k6 load testing tool installed (brew install k6)
  • Test store with API access (never load test production)
  • Understanding of Shopify rate limits per plan

Instructions

Step 1: Understand Capacity Constraints

Your app's throughput is bounded by Shopify's rate limits, not your infrastructure:

PlanGraphQL PointsRestore RateMax Sustained QPSBurst Capacity
Standard1,00050/sec~10 queries/sec1,000 points burst
Shopify Plus2,000100/sec~20 queries/sec2,000 points burst

A typical product query costs 10-50 points. At 50 points/query, Standard supports ~1 query/second sustained.

Step 2: k6 Load Test Script

k6 script with Shopify-specific custom metrics (throttle tracking, query cost trends, error rates) and automatic request pacing.

See k6 Load Test Script for the complete test script.

Step 3: Run Load Test
bash
# Against a test store — NEVER production
k6 run \
  --env SHOPIFY_STORE=dev-store.myshopify.com \
  --env SHOPIFY_ACCESS_TOKEN=shpat_test_token \
  shopify-load-test.js

# Output results to InfluxDB for Grafana dashboards
k6 run --out influxdb=http://localhost:8086/k6 shopify-load-test.js
Step 4: BFCM / Flash Sale Preparation

Pre-BFCM preparation including cache pre-warming, Storefront API offloading, bulk inventory sync, and Kubernetes HPA configuration for webhook processing.

See BFCM Preparation for application-level and infrastructure scaling patterns.

Output

  • Load test script calibrated to Shopify rate limits
  • Performance baseline documented
  • BFCM preparation checklist completed
  • Infrastructure scaling configured for webhook volume

Error Handling

IssueCauseSolution
k6 shows high error rateHitting rate limitsReduce VUs, increase sleep between requests
All requests THROTTLEDExceeding 50 points/secSpace queries further apart
Webhooks backing upSlow processingRespond 200 immediately, queue processing
Cache stampede on sale startAll caches expire at onceStagger cache TTLs, pre-warm

Examples

Quick Capacity Estimate
bash
# How many queries can you sustain?
# Standard plan: 50 points/sec restore
# Your query costs: check with debug header

curl -sf "https://$STORE/admin/api/${SHOPIFY_API_VERSION:-2025-04}/graphql.json" \
  -H "X-Shopify-Access-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -H "Shopify-GraphQL-Cost-Debug: 1" \
  -d '{"query": "{ products(first: 10) { edges { node { id title } } } }"}' \
  | jq '"Query cost: \(.extensions.cost.actualQueryCost) points. Max sustained: \(50 / .extensions.cost.actualQueryCost) queries/sec"'
