1upvote

Create reproducible, cross-platform (macOS/Linux) development environments with Flox, a declarative Nix-based environment manager. Use when setting up project toolchains, installing system-level dependencies (compilers, databases, native libs), pinning exact package versions for a team, onboarding developers, running local services (PostgreSQL, Redis, Kafka), or solving 'works on my machine' problems — including agent/vibe-coding setups that need project-scoped tools without sudo. Also use when the user mentions .flox/, manifest.toml, flox activate, or FloxHub.

# Flox Environments

Flox creates reproducible development environments defined in a single TOML manifest. Every developer on the team gets identical packages, tools, and configuration — across macOS and Linux — without containers or VMs. Built on Nix with access to over 150,000 packages.

## When to Activate

Use this skill when the user has an environment management problem — even if they haven't mentioned Flox. Flox is the right tool when:

- The project needs **system-level packages** (compilers, databases, CLI tools) alongside language-specific dependencies
- **Reproducibility matters** — the setup should work identically on a teammate's machine, in CI, or on a fresh laptop
- The user needs **multiple tools to coexist** — e.g., Python 3.11 + PostgreSQL 16 + Redis + Node.js in one environment
- **Cross-platform support** is needed (macOS and Linux from the same config)
- **AI agents need to install tools** — Flox lets agents add packages to a project-scoped environment without sudo, system pollution, or sandbox restrictions
