nix-toolkit

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:

1. package-diffing — package-diffing.md
2. build-debugging — build-debugging.md
3. closure-analysis — closure-analysis.md
4. dependency-forensics — dependency-forensics.md
5. flake-maintenance — flake-maintenance.md
6. eval-performance — eval-performance.md
7. ifd-remediation — ifd-remediation.md
8. 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.
