Profile-guided optimisation skill for C/C++ with GCC and Clang. Use when squeezing maximum runtime performance after standard optimisation plateaus, implementing two-stage PGO builds, collecting profile data, or applying BOLT for post-link optimisation. Activates on queries about PGO, profile-guided optimization, fprofile-generate, fprofile-use, instrumented builds, or BOLT.
C++ and Rust memory model skill for concurrent programming. Use when understanding memory ordering, writing lock-free data structures, using std::atomic or Rust atomics, diagnosing data races, or selecting the correct memory order for atomic operations. Activates on queries about memory ordering, acquire-release, seq_cst, relaxed atomics, happens-before, memory barriers, std::atomic, or Rust atomic ordering.
Rust profiling skill for performance analysis. Use when generating flamegraphs from Rust binaries, measuring monomorphization bloat with cargo-llvm-lines, analysing binary size with cargo-bloat, microbenchmarking with Criterion, or interpreting inlined frames in profiles. Activates on queries about cargo flamegraph, cargo-bloat, cargo-llvm-lines, Criterion benchmarks, Rust performance profiling, or binary size analysis.
Rust cross-compilation skill. Use when building Rust binaries for a different target architecture or OS, using cross or cargo-zigbuild for hermetic cross-compilation, configuring .cargo/config.toml for cross targets, or targeting embedded and bare-metal systems. Activates on queries about Rust cross-compilation, rustup targets, cross tool, cargo-zigbuild, aarch64-unknown-linux-gnu, thumbv7m-none-eabi, or building for embedded.
Rust compiler skill for systems programming. Use when selecting RUSTFLAGS, configuring Cargo profiles, tuning release builds, reading assembly or MIR output, understanding monomorphization, or diagnosing compilation errors. Activates on queries about rustc flags, Cargo.toml profiles, opt-level, LTO, codegen-units, target-cpu, emit asm, MIR, or Rust build performance.
Rust unsafe code skill for systems programming. Use when writing or reviewing unsafe Rust, understanding what operations require unsafe, implementing safe abstractions over unsafe code, auditing unsafe blocks, or understanding raw pointers, transmute, and extern. Activates on queries about unsafe Rust, raw pointers, transmute, unsafe blocks, writing safe wrappers, UnsafeCell, unsafe trait impl, or auditing unsafe code.
Rust FFI skill for C interoperability. Use when calling C libraries from Rust, generating Rust bindings with bindgen, exporting Rust functions to C with cbindgen, writing safe wrappers around unsafe FFI, or linking system and vendor libraries. Activates on queries about bindgen, cbindgen, extern "C", unsafe FFI, Rust C bindings, linking C from Rust, or sys crates.
CPU cache optimization skill for C/C++ and Rust. Use when diagnosing cache misses, improving data layout for cache efficiency, using perf stat cache counters, understanding false sharing, prefetching, or structuring AoS vs SoA data layouts. Activates on queries about cache misses, cache lines, false sharing, perf cache counters, data layout optimization, prefetch, AoS vs SoA, or L1/L2/L3 cache performance.
NestJS framework for building efficient, scalable Node.js server-side applications. Use when working with NestJS apps, controllers, modules, providers, dependency injection, pipes, guards, interceptors, or building REST/GraphQL APIs.
