Change a studio app's price, or reconcile prices that have drifted apart, across every place a price is written — prices.json, the App Store IAP, the Lemon Squeezy product, both profiles, store metadata, media scripts and captions, the site copy, and the .storekit files in the app repos. Use when the user raises or lowers a price, says a price is wrong or out of date, asks what an app costs, mentions the direct and store prices disagreeing, or after any price change in App Store Connect or…
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
# Price sync — one price, many files A price in this studio is written in more than fifty files across four repos. Every rise so far has reached App Store Connect and one profile and left the rest behind: when this skill was written, three of four direct prices and five `.storekit` files were stale, some by a year. **`$APP_HUB/prices.json` is the source of truth.** Everything else quotes it. When a document disagrees, the document is wrong — unless reality moved, in which case `prices.json` is updated first and everything follows from there. This file is the method. What running it taught — the runs behind each rule — is in [LESSONS.md](LESSONS.md). ## Prerequisites - **Tools:** Python 3 (stdlib) for `verify_prices.py`; `fastlane` (`brew install fastlane`) or spaceship only to read a live App Store price by hand. - **Credentials:** none for the file scan. `--stores` resolves an App Store Connect API key through apple-track's shared credential resolver (`ASC_KEY_ID` / `ASC_ISSUER_ID` / `ASC_KEY_PATH`, or `credentials.json` under `$KEYS_ROOT`). Lemon Squeezy is a dashboard edit; no key is used. …

How to install
mdr add yybd/app-factory/price-sync@sha256:b280b2138e0308fcThe line at the top of this page pins the label git:20261014.d2eaaa9, 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.
