By name: nix-toolkit description: Nix operational playbooks for package diffs, build debugging, closure analysis, dependency forensics, flake maintenance, and evaluation performance tuning. Use when comparing Nix build outputs, diagnosing derivation failures, finding unexpected runtime/build dependencies, inspecting closure size, maintaining flakes, or profiling slow NixOS/Home Manager/Nixvim evaluation.
Nix Toolkit
Router for Nix operational/debugging workflows. For writing or refactoring Nix
modules, expressions, overlays, packages, or flake outputs, use writing-nix.
Route to one mode; load only that reference:
- package-diffing — package-diffing.md
- build-debugging — build-debugging.md
- closure-analysis — closure-analysis.md
- dependency-forensics — dependency-forensics.md
- flake-maintenance — flake-maintenance.md
- eval-performance — eval-performance.md
- ifd-remediation — ifd-remediation.md
- nix-authoring — delegate to
writing-nix
If intent is unclear, ask before proceeding.
Read scripts.md when a first-pass report or repeatable measurement can replace manual command assembly.
See operating-rules.md for cross-skill routing and reporting rules.
