-# RxReactor — Claude Notes
-
-## Working style
-
-Always confirm with the user before making any changes.
-
-## Danger / danger-kotlin notes
-
-The project uses `danger/kotlin@1.3.4` (Docker-based) via `.github/Dangerfile.df.kts`.
-
-Plugins in use:
-- `io.github.ackeecz:danger-kotlin-lint` — detekt inline comments (requires `basePath` set in root `build.gradle` detekt block)
-- `com.gianluz:danger-kotlin-android-lint-plugin` — Android lint inline comments
-- `io.github.ackeecz:danger-kotlin-testing` — JUnit test result reporting
-
-Kotlin compiler warnings are parsed from `build.log` (captured via `tee` in CI) using the
-K2 compiler format: `w: <file>:<line>:<col> <message>`.
-
-The `danger/kotlin` action uses the built-in `GITHUB_TOKEN`; no separate PAT is required.
