This repo is used by opensafely-core/research-action for testing. It should:

• [ ] be added to the Researcher Experience Team's list of repos
• [x] have a clear README.md
• [x] have a dataset definition (ehrQL) rather than a study definition (cohort-extractor)
• [x] have main rather than master
• [x] have branch protection rules

As the study within this repo is also a dependency of opensafely-core/research-action, then the study should be tested on a schedule to ensure that any changes to opensafely (i.e. the CLI) don't break it.

For testing on a schedule - (you probably already know) - GHA workflows allow a CRON-type syntax.

In cox-ipw we run our little test once a week with

on:
  pull_request:
  workflow_dispatch:
  schedule:
    - cron: '37 2 * * TUE'

(I don't know if there is a cleverer way to do it based on checking for new releases of the CLI)
