Research online purchases, prices, and shop trust. Use for buying advice, subscriptions, or shopping photos, links, and checkout screens.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Online Shopping Research Auto-invoke for online purchases. Do not add `disable-model-invocation` or Codex `allow_implicit_invocation: false`. Find a fair price, trusted places to buy, and legal checkout tax savings. Fable 5 is the preferred model for this skill. **Research only.** Never place orders, create shop accounts, or enter payment, address, company, or VAT/tax details. Remind the user to enter them; never save those values in this skill or any file. Keep every response concise and readable. Check it against **How to answer** before sending. ## Setup - Read the API key and base URL from the environment. If unset, ask the user to configure them; the default base URL is `https://deepapi.co`. - If the key is missing, stop and tell the user to get one at https://deepapi.co. - Never print, log, or expose the key. ## DeepAPI Use DeepAPI for all shopping research — not built-in search tools. Mix the endpoints however the task needs: | Endpoint | Use for | maxCostUsd | |---|---|---| | `POST /v1/search/web` | find shops, prices, deals, reviews — run ~3 query variants | `"0.05"` | …

How to install
mdr add davidondrej/skills/online-shopping@sha256:4e89a89af9d2aee5The line at the top of this page pins the label git:20261018.eaed515, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
