Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
1 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by abracadabra50 on GitHub. Read the source before you install it.

Installation

Install the Grocery Api AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/abracadabra50/open-supermarkets/tree/main/skills/api
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/abracadabra50/open-supermarkets.git /tmp/open-supermarkets
mkdir -p .claude/skills
cp -r /tmp/open-supermarkets/skills/api .claude/skills/grocery-api

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Grocery Api in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Grocery Api on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Grocery Api is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Grocery API Skill

Use this skill when the user asks about Sainsbury's groceries, favourites, searching products, adding/updating/removing basket items, or viewing the basket.

The local API must already be running on port 7876:

bash
GROC_API_PORT=7876 npm run api

Commands

Run from the repo root:

bash
node skills/api/wrapper.js fav-search "milk"
node skills/api/wrapper.js search "milk"
node skills/api/wrapper.js favourites
node skills/api/wrapper.js basket
node skills/api/wrapper.js add <product-id> [qty]
node skills/api/wrapper.js remove <item-id>
node skills/api/wrapper.js update <item-id> <qty>

All commands return JSON from the local API.

Add-to-basket workflow

When the user asks to add an item to the basket:

First search favourites:

bash
node skills/api/wrapper.js fav-search "USER ITEM"

If there is a clear favourite result that matches the user's intent, add it directly:

bash
node skills/api/wrapper.js add <product-id> [qty]

If there are multiple plausible favourite results, ask the user which one to add. Include names, prices, and product IDs.

If there are no good favourite matches, or if the user explicitly asks to look outside favourites, use regular search:

bash
node skills/api/wrapper.js search "USER ITEM"

For regular search results, always confirm with the user before adding anything to the basket.

After adding, show or summarize the basket:

bash
node skills/api/wrapper.js basket

Remove/update workflow

When the user asks to remove or update an item:

First inspect the basket to get basket item IDs:

bash
node skills/api/wrapper.js basket

Use the basket item_id, not the product ID:

bash
node skills/api/wrapper.js remove <item-id>
node skills/api/wrapper.js update <item-id> <qty>

If the item to change is ambiguous, ask the user which basket item they mean.
After removing or updating, show or summarize the basket.

Notes

Prefer favourites over regular search for add requests.
Do not add ambiguous items without asking.
Do not use regular search additions without confirmation.
Use the product_uid as the product ID for add.
Use the basket item_id for remove and update.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Grocery Api AI skill do?

Use the local groc HTTP API to search Sainsbury's groceries, search favourites, add/update/remove basket items, and view basket.

Why use Grocery Api on TypingMind?

Because you install it once and use it with any model. Grocery Api is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Grocery Api in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/abracadabra50/open-supermarkets/tree/main/skills/api. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Grocery Api?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Grocery Api?

As many as you like. As long as a model supports skills, you can use Grocery Api with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Grocery Api AI skill free?

Yes. It is published on GitHub by abracadabra50 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
