The Agent Skills Directory

[COMMAND_EXECUTION]: The skill references standard command-line tools for development, auditing, and testing.
cargo tree and cargo update are used for managing and verifying the versions of the jni crate dependencies.
llvm-nm is recommended for inspecting exported symbols to debug linkage errors.
adb shell commands are used to enable CheckJNI on Android devices for runtime verification.
gradlew is used to run instrumentation tests for binding verification.
[EXTERNAL_DOWNLOADS]: The skill provides links to well-known, official documentation for Android development.
It references the official Android NDK guides on developer.android.com for JNI tips and class loading behaviors.
[DYNAMIC_EXECUTION]: The instructions cover the necessary use of unsafe Rust features for FFI (Foreign Function Interface) operations.
The skill promotes safe practices by requiring SAFETY comments and explicit invariant checks when using from_raw pointers or mapping direct buffers.
It provides correct templates for JNI_OnLoad and panic guards to prevent native aborts, which is a key stability and security best practice when crossing the language boundary.
