What it does

Price Watch is an agent skill from amd/gaia. 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.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Build AI agents for your PC. The licence is MIT.

When your agent uses it

  • The user asks to watch a price
  • Tell them when something gets cheaper

Example prompts

  • “/price-watch”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Recall the history. recall(query="price:", limit=20) and
  2. Fetch the page. fetch_page(url).
  3. Extract the current price. Pull the number and its currency. Watch for
  4. Compare. Alert when the current price is below the recorded low (or below
  5. Record the observation.

What it can do on your machine

Read from SKILL.md and the folder at commit 05fb50b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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.

Context cost

Price Watch loads about 658 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 319 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~658

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.

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:

  1. Recall the history. recall(query="price:<product-slug>", limit=20) and take the lowest price previously recorded.
  2. Fetch the page. fetch_page(url).
  3. 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.
  4. 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.
  5. 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

<product> — now <price>, previously <old low> (<date>). Down <delta>. <url>

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.
