Create and modify NixOS and Home-Manager modules
Hardens systemd services against security issues using sandboxing, capability restriction, and syscall filtering. Use when creating or modifying systemd services, writing NixOS modules with systemd.services, reviewing service security, or whenever a serviceConfig block is involved. Ensures services follow defense-in-depth principles with minimal privilege.
Write Nix code using repo conventions
Write and review Conventional Commits commit messages (v1.0.0) for semantic versioning and changelogs. Use when drafting git commit messages, PR titles, release notes, or enforcing conventional commit format like `type(scope): subject`, `BREAKING CHANGE`, footers, and `revert`.
Manages version control with Jujutsu (jj), including rebasing, conflict resolution, and Git interop. Use when tracking changes, navigating history, squashing/splitting commits, or pushing to Git remotes.
Manage background jobs, capture command output, and handle session multiplexing. Use when running long commands, capturing output from detached processes, or managing concurrent tasks in headless environments.
