nixos

Use when designing, refactoring, debugging, or testing complex systems by defining the desired end state, decomposing it into atomic contracts, composing those atoms into cascades, and proving risky paths in realistic simulations before touching real systems.

Load full context for the NixOS configuration at /etc/nixos. Use before answering questions about this repo or changing system, disk, boot, recovery, BTRC, or simulator behavior.

Use when reviewing, writing, or refactoring code where elegance, idiom, API shape, naming, abstraction boundaries, or verification quality matter. Especially relevant for BTRC, NixOS, stdlib/compiler work, CLI tools, shell/process APIs, editor tooling, simulator tests, and full-stack systems where awkward call sites may indicate a deeper language, stdlib, or architecture problem.
