Usage

# Rebuild system
sudo nixos-rebuild switch --flake .#nixos

# Update flake inputs
nix flake update

# Enter a dev shell
nix develop .#base
nix develop .#go
nix develop .#evm
nix develop .#kucoin

macOS (with direnv)

1. Install Nix and enable flakes:

   echo 'experimental-features = nix-command flakes' >> ~/.config/nix/nix.conf

2. Install direnv and hook it into your shell (~/.zshrc):

   brew install direnv
   echo 'eval "$(direnv hook zsh)"' >> ~/.zshrc

3. In your project directory, create an .envrc:

   echo 'use flake /path/to/nixos-config#kucoin' > .envrc
   direnv allow

   Or to use a shell from this repo directly:

   echo 'use flake github:your-username/nixos-config#kucoin' > .envrc
   direnv allow

Skills

Custom Claude Code skills in skills/.

diff-to-sop

Converts a git diff into a step-by-step SOP with modified files, functions, and minimal code blocks.

Install into Claude Code — add to .claude/settings.json in your project:

{
  "pluginDirectories": ["/path/to/nixos-config/skills"]
}

Or pass it per-session:

claude --plugin-dir /path/to/nixos-config/skills

Usage:

# On the latest commit
git diff HEAD~1 HEAD | claude -p "Use diff-to-sop skill"

# With Chinese output saved to file
git diff -U10 master..feature | claude -p "Use diff-to-sop skill. Output in Chinese into a markdown file"
