Flox Environments

This one teaches Claude to set up Flox environments, which are declarative, Nix-based dev environments that work identically across macOS and Linux without containers. It's pitched at the "works on my machine" problem and agent coding scenarios where you need project-scoped system packages without sudo. The guide covers manifest.toml structure, package installation patterns including version pinning and conflict resolution, and language-specific recipes for Python with uv, Node, Rust, Go, and C++. Useful context on $FLOX_ENV vs $FLOX_ENV_CACHE for package paths versus persistent storage like venvs. If your project needs reproducible toolchains with databases, compilers, and native libs all declared in one file, this covers the patterns.
