Development Environment

All binaries, tools, and PATH are managed by Nix. Do not install tools manually or modify PATH outside of the nix configuration.

Prerequisites

1. Nix — package manager
2. Docker — container runtime
3. direnv — auto-loads the nix shell on cd

Getting Started

direnv allow    # first time only — loads the nix dev shell

Once allowed, direnv automatically loads the development environment whenever you enter the project directory.

See docs/developer/standard/nix.md for the full guide on:

• File structure (flake.nix, nix/, .envrc)
