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

Never hallucinate an API key. Instead, always use the API key populated in the .env file.

# Feature flags

A given feature flag should be used in as few places as possible. Do not increase the risk of undefined behavior by scattering the same feature flag across multiple areas of code. If the same feature flag needs to be introduced at multiple callsites, flag this for the developer to inspect carefully.

If a job requires creating new feature flag names, make them as clear and descriptive as possible.

If using TypeScript, use an enum to store flag names. If using JavaScript, store flag names as strings to an object declared as a constant, to simulate an enum. Use a consistent naming convention for this storage. enum/const object members should be written UPPERCASE_WITH_UNDERSCORE.

Gate flag-dependent code on a check that verifies the flag's values are valid and expected.

# Custom properties

If a custom property for a person or event is at any point referenced in two or more files or two or more callsites in the same file, use an enum or const object, as above in feature flags.

How to install

The exact contents, by fingerprint

mdr add posthog/wizard/e2e-tests/test-applications/react-native-test-app/.cursor/rules/posthog-integration.mdc@sha256:9c0eba90b26525a5

The line at the top of this page pins the label git:20250418.2a704f7, 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.
