How to Install
These are Shopify inventory agent skills, not official Anthropic or OpenAI assets. They are designed to be GitHub-distributed building blocks that fit agentic workflows such as Claude Code, Codex, and similar toolchains where reusable instructions, scripts, and resources matter.
Each skill installs from its GitHub repo. Use the repo slug shown on the skill page, then run:
npx skills add useretrace/<repo>That is the install path for Claude Code, Codex, and similar skills-compatible workflows.

How to use the skills
Each skill is distributed through GitHub and can be installed independently. In practice, most merchants or operators start with one of two paths:
1. Clean the export first, then run analysis
Start with Inventory Export Cleaner if files are messy
2. Start with the inventory question first
Then add adjacent skills as needed

Why Retrace ships these for free
Retrace is building inventory tracking for Shopify. These free skills are useful on their own, but they also show the kinds of questions merchants need answered from real operational data: what to reorder, what to cut, what changed, and whether the export can be trusted in the first place.
Frequently asked questions
Practical details about the skill collection, install path, and where GitHub fits into the workflow.
What are Shopify inventory agent skills?
Shopify inventory agent skills are focused tools that process exports such as product and order CSVs to answer a specific operational question. In this collection, each skill handles one job like dead stock analysis, ABC analysis, replenishment, export cleanup, or period comparison.
Are these web apps or GitHub tools?
These are GitHub-distributed agent skills. The website explains what each one does and helps users choose the right one, while GitHub is the execution and install destination.
Are these Claude Code skills or Codex skills?
They are best described as Shopify inventory agent skills. They are structured so they can fit Claude Code, Codex, and similar agent workflows, but they are published by Retrace rather than by Anthropic or OpenAI.
How do I actually use one of these skills?
Choose the skill that matches your inventory problem, open the GitHub repo, and follow the install and usage instructions there. The website is the explanation layer; GitHub is the execution layer.
Which skill should I start with first?
If your files are messy, start with Inventory Export Cleaner. If your main question is about stale inventory, start with Dead Stock. If your main question is about ordering, start with Inventory Health.
Do I need Shopify exports for every skill?
Most of the skills are designed for Shopify exports first, but several also support generic sales CSVs with column overrides. The exact requirements are listed on each repo.
Why not just use a calculator?
Calculators work when you already know every input and only need one formula. These skills are more useful when you need to process real exports and produce a full report, classification, or cleanup result across many SKUs.
How do I install one of these skills?
Open the repo and run npx skills add useretrace/<repo> with the repo name shown on that page. These skills are designed to install cleanly in Claude Code, Codex, and similar skills-compatible workflows.
Do I need a special installer for each skill?
No. The install pattern is the same across the collection. Only the repo slug changes from skill to skill.
Start with the inventory question, not the tool taxonomy
Choose the skill that matches the problem you need to solve today, then install it from GitHub with the repo slug and run it on real Shopify exports.
