schema: spec-driven

context: |
  Project: SmsReceive
  Primary platform: Android
  Reference build environment: Weather reference project
  Target device: Xiaomi 12S, HyperOS 3, Android 15
  Primary goal: build a personal Android app that can receive and surface SMS verification codes on the user's own phone.
  Audience: an experienced Android engineer who wants a practical Android implementation plan before coding.

rules:
  proposal:
    - Write in Chinese
    - Always include Why, What Changes, Capabilities, Impact, Validation
    - Make the recommended SMS capture path explicit instead of listing only generic options
    - Keep Android Studio, Gradle, and JDK setup out of scope; reuse the Weather project build environment as reference
  design:
    - Write in Chinese
    - Include API strategy, Android 15 permission constraints, Xiaomi/HyperOS validation risks, parsing strategy, diagnostics, privacy boundaries, and test strategy
    - Treat implementation as a personal sideload/debug app, not a Play Store compliance exercise
  tasks:
    - Write in Chinese
    - Break work into actionable engineering steps
    - Separate spec/design validation from implementation and device validation
    - Include checks for unintended EOF newline changes before commit or push
