What It Does

Helps you migrate from nix-shell to devenv or create new devenv projects with:

• Migration guidance: nix-shell → devenv conversion patterns
• Language configs: Python (uv/poetry/venv), JavaScript, Go, Rust, Elm
• Services: PostgreSQL, Redis, MySQL, MongoDB, Elasticsearch
• Process orchestration: Health checks, dependencies, restart policies
• Ready-to-use templates: From basic to full-stack setups
• Platform-specific solutions: Linux patchelf, macOS frameworks, WSL

---

Usage

Claude Code automatically triggers this skill when you:

You: "Migrate my nix-shell setup to devenv"
You: "Set up devenv with Python and PostgreSQL"
You: "Why is my devenv build failing?"

Real-World Example

Based on real-world migration experience:

Before (nix-shell):

• 150+ line default.nix with manual setup
• Complex patchelf logic for Linux
• Manual process orchestration

After (devenv):

• 80-100 line devenv.nix
• Automatic platform handling
• Declarative processes with health checks
