Set up a project development environment with wrapper scripts and/or a Nix flake.

Parameters

• location: Desired location for setup artifacts.

• "machine-local": Inside .my/ (ignored by git, good for personal tools).

• "project-local": Root level (e.g., bin/ , flake.nix ).

• setup_types: What to set up ("wrapper", "flake", or "both").

If these parameters are not explicitly provided in the request, infer them from context or ask the user for clarification before proceeding.

Process

For each setup type selected:

Wrapper Scripts

Determine paths based on location:

• Machine-local: .my/bin/ with my- prefix

• Project-local: bin/ , ask about naming:

• Generic: test , lint , fmt , build , dev

• Prefixed (default): <project-name>-test , etc.

Invoke the code-analyze-project skill to:

• Detect project type

• Recommend wrappers (test, lint, fmt, build, dev commands)

Present recommended wrappers and ask which to create

Create wrapper directory if needed

If machine-local: Create .my/.gitignore with content *

Create wrapper scripts with template:

#!/usr/bin/env bash set -euo pipefail <command>

• Make executable: chmod +x <dir>/*

Nix Flake

Determine path based on location:

• Machine-local: .my/flake.nix

• Project-local: flake.nix

Check for existing flake at the determined path

Detect project type and required packages:

• Node.js: package.json → nodejs, npm/pnpm/yarn

• Python: pyproject.toml, setup.py → python3, pip/poetry/uv

• Go: go.mod → go, gopls

• Rust: Cargo.toml → cargo, rustc

• Ruby: Gemfile → ruby, bundler

• Other: check for Makefile, CMakeLists.txt, etc.

Generate flake using the template in templates/flake.nix

• Use buildInputs (not packages ) for dependencies

• No shellHook unless absolutely necessary

• Keep it simple and minimal

• If updating existing flake, preserve custom inputs/outputs but simplify structure

If machine-local: Create .my/.gitignore with content * if not exists

Verify the flake: nix flake check path:.

• If verification fails, fix issues and re-verify

Output

• Project type detected

• Wrapper/flake location created

• Scripts/flake created (with descriptions)
