name	nix-toolkit
description	Nix operational workflows for package diffs, build failures, closure analysis, dependency forensics, flake maintenance, and evaluation performance. Use for diagnosing Nix builds or outputs; use writing-nix for expression and module authoring.

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. activation-verification: activation-verification.md
9. nix-authoring: delegate to writing-nix

If intent is unclear, ask before proceeding.

NixOS Privilege Wrappers

If sudo resolves outside /run/wrappers/bin, use /run/wrappers/bin/sudo. Nix store binaries lack setuid privileges. Diagnose with type -a sudo, then prepend the wrapper directory for that command. Never chmod a store path or replace the wrapper.

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.
