# Copilot Instructions — oncall-mobile-android This file is a pointer, not a content store. For real docs, read in order: 1. `AGENTS.md` — role of the app, single-config bootstrap, package layout, key Kotlin entry points. 2. `README.md` — build + run instructions. 3. `TESTING.md` — local test setup. 4. `flake.nix` — Nix dev shell (Android SDK + JDK pinning). Package namespace is `com.centralcloud.oncall` (post-rename — `io.heckel.ntfy` is gone from the source tree). SMS-relay subsystem lives under `com.centralcloud.oncall.sms.*`; see those files' inline docstrings.
