price-watch

Check product pages for a price drop, comparing against the lowest price seen before and alerting only on a new low. Use when the user asks to watch a price, track a deal, or tell them when something gets cheaper.

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.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by amd on GitHub. Read the source before you install it.

Installation

Install the Price Watch 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/amd/gaia/tree/main/hub/skills/price-watch
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/amd/gaia.git /tmp/gaia
mkdir -p .claude/skills
cp -r /tmp/gaia/hub/skills/price-watch .claude/skills/price-watch

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

Use it in TypingMind

Enable Price Watch 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 Price Watch 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 Price Watch 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.

Price Watch

A fork of source-watch where the "item" is a product and "interesting" means cheaper than it has ever been. It shows the shape worth copying: memory holds a running extreme, not just a list of things already seen.

Configure

Products — a list of product URLs the user cares about.
Memory key — price:<product-slug>, one per product.
Floor (optional) — alert only below this price regardless of history.

Procedure

For each product URL:

Recall the history. recall(query="price:<product-slug>", limit=20) and take the lowest price previously recorded.
Fetch the page. fetch_page(url).
Extract the current price. Pull the number and its currency. Watch for the traps: a struck-through list price next to the real one, a subscription price next to the one-time price, and a per-unit price on a multipack. If you cannot find a price with confidence, say so — do not guess, and do not record a guessed number, because a wrong low poisons every future comparison.
Compare. Alert when the current price is below the recorded low (or below the configured floor). Otherwise report the current price and the delta in one line.
Record the observation. remember(fact="price:<product-slug>: <amount> <currency> on <YYYY-MM-DD> — <url>", category="fact"). Record every observation, not only the lows, so the history is a real series.

Report format

— now , previously (). Down .

Honest limits

Runs on demand, not on a schedule — the scheduler cannot run skills yet (see source-watch for the detail).
Many retailers vary price by region, login state, or bot detection. The price a fetched page shows may not be the price the user is offered. Say which page you read.
Needs memory enabled for the history to survive between runs.

Fork this

Swap "lowest price" for any running extreme — highest rating, largest discount, shortest lead time — and the same three steps (recall the extreme, extract the current value, alert on a new record) carry over unchanged.

Frequently asked questions

What does the Price Watch AI skill do?

Why use Price Watch on TypingMind?

Because you install it once and use it with any model. Price Watch 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 Price Watch in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/amd/gaia/tree/main/hub/skills/price-watch. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Price Watch?

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 Price Watch?

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

Is the Price Watch AI skill free?

Yes. It is published on GitHub by amd 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.
