Go performance optimization guidelines for profiling, allocation, GC tuning, concurrency, PGO, and I/O. This skill should be used when writing, reviewing, or optimizing Go code for performance. Triggers on tasks involving slow services, high latency, high memory usage, memory leaks, goroutine leaks, GC pressure, CPU profiling, pprof analysis, allocation reduction, sync.Pool, mutex contention, HTTP client tuning, Profile-Guided Optimization, GOMEMLIMIT tuning, Go 1.24 features, Swiss Tables, or any Go performance investigation.

Expert-level Rust performance optimization guidelines for build profiles, allocation, synchronization, async/await, and I/O. This skill should be used when writing, reviewing, or optimizing Rust code for performance. Triggers on tasks involving slow Rust code, large binary size, long compile times, LTO configuration, release profile tuning, allocation reduction, clone avoidance, lock contention, BufReader/BufWriter, flamegraph analysis, async runtime issues, Tokio performance, spawn_blocking, parking_lot vs std sync, or any Rust performance investigation.

TypeScript performance optimization guidelines for build times, type-checking, declaration emit, and editor responsiveness. This skill should be used when writing, reviewing, or optimizing TypeScript code and tsconfig settings. Triggers on tasks involving slow builds, slow type-checking, CI timeouts, editor lag, tsserver memory issues, monorepo configuration, project references, incremental builds, declaration emit, isolatedDeclarations, --noCheck flag, TypeScript 5.6+ features, TypeScript 7 migration, or any TypeScript performance investigation.
