## Design

Each skill follows the [SKILL.md format](https://github.com/anthropics/skills). The body stays under 500 lines; detailed reference material lives in `references/` and is loaded only when needed (progressive disclosure).

Skills cross-reference each other where workflows overlap (e.g., `rust-profiling` + `linux-perf`, `zig-cinterop` + `zig-build-system`, `sanitizers` + `fuzzing`, `embedded-rust` + `linker-scripts`, `ebpf` + `ebpf-rust`).
