General instructions

These are general instructions for agentic AI usage shared across many systems

Command availability

• The system has access to nix, but only uses nix flakes, not channels.
• If you attempt to run a shell command but it isnt available, try finding the nix package and using a nix shell to run it instead.

Command output / log output

J-Swift

{ pkgs, ... }:

{
  cachix.enable = false;

  languages.python = {
    enable = true;
    venv.enable = true;
    venv.requirements = ''
      pillow

J-Swift

Devenv / nix

The project uses devenv and has access to nix. If a tool is not available, check if its provided via the devenv packages or reference it using a nix shell.

When running commands, you usually will want to do so through devenv shell to ensure bundler and gems are setup properly.

If a tool is used frequently, suggest adding it to the devenv packages.

Sonarr 4

Current nix packages only supports Sonarr 3. It also downloads the release artifact instead of compiling from source.

NOTE(jpr): this version expects nix-npm-buildpackage to be accessible via its overlay.

filename = 'iterm_colors.json'

  "black",
