Setup Mac Dev

macOS Development Setup

Perform setup directly with tools. Do not offload commands to the user unless a GUI prompt or privileged approval is required.

Use non-interactive flags wherever supported (-y, --yes, NONINTERACTIVE=1).

Before starting, tell the user:

"Setting up this Mac for development now. This may require command-line tools installation and admin approval prompts."

Then execute each step and report concise progress updates.

Step 1: Preflight checks

Run checks first and record results.

uname -sm
which brew || true
which node || true
which npm || true
which npx || true
which uv || true
xcode-select -p || true

Interpretation:

• If required tools already exist, skip reinstallation and keep going.
• If xcode-select -p fails, treat missing Command Line Tools (CLT) as a likely blocker for git and Homebrew.

Step 2: Ensure Xcode Command Line Tools (mandatory)

If CLT is missing:

xcode-select --install

Immediately trigger the installer when missing. Do not defer this step.

If the goal is to avoid GUI approval prompts and sudo access is available, prefer a non-GUI install path:

CLT_LABEL="$(softwareupdate -l | awk -F'* ' '/Command Line Tools/ {print $2}' | sed 's/^ *//' | tail -n 1)"
if [ -n "$CLT_LABEL" ]; then
  sudo softwareupdate -i "$CLT_LABEL" --verbose
fi

Notes:

• This may open a system dialog and require user acceptance.
• xcode-select --install does not support a --yes auto-approve flag.
• Re-check with xcode-select -p after the install prompt is accepted.
• Continue with user-local installs when CLT remains unavailable.

Step 3: Install Homebrew when possible

Check whether Homebrew already exists:

which brew

If missing, attempt install:

NONINTERACTIVE=1 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

If Homebrew install fails due missing admin privileges or CLT, continue with no-admin fallback in Step 4.

Step 4: Install Node.js (preferred: Homebrew, fallback: user-local)

Preferred path when Homebrew is available:

brew install node

Fallback path without Homebrew:

mkdir -p "$HOME/.local" "$HOME/.local/bin"
curl -fsSL "https://nodejs.org/dist/v22.22.0/node-v22.22.0-darwin-arm64.tar.gz" -o "$HOME/.local/node-v22.22.0-darwin-arm64.tar.gz"
tar -xzf "$HOME/.local/node-v22.22.0-darwin-arm64.tar.gz" -C "$HOME/.local"
ln -sfn "$HOME/.local/node-v22.22.0-darwin-arm64" "$HOME/.local/node"
ln -sfn "$HOME/.local/node/bin/node" "$HOME/.local/bin/node"
ln -sfn "$HOME/.local/node/bin/npm" "$HOME/.local/bin/npm"
ln -sfn "$HOME/.local/node/bin/npx" "$HOME/.local/bin/npx"

Add local bin to current shell session when using fallback:

export PATH="$HOME/.local/bin:$PATH"

Step 5: Install uv and Python

Install uv:

curl -LsSf https://astral.sh/uv/install.sh | sh

Ensure uv is on PATH for the current session:

export PATH="$HOME/.local/bin:$PATH"

Install a managed Python:

uv python install

Step 6: Install skills packages

Use npx skills add with global scope when not inside a project repository:

GH_TOKEN=<token> npx skills add fwfutures/rome2rio-skills fwfutures/vibe-a-thon -g -y

If clone fails (often due CLT/git or auth issues), fallback to zipball workflow:

1. Download each repository zipball from GitHub API with GH_TOKEN.
2. Unzip into a temp folder.
3. Install from local extracted path:

npx skills add /path/to/extracted/repo -g -y

Security note:

• Keep tokens in environment variables.
• Do not echo tokens into logs or summaries.

Step 7: Verify tooling and skills

Run final verification commands:

export PATH="$HOME/.local/bin:$PATH"
which brew || true
node -v
npm -v
npx -v
uv --version
uv python list
npx skills list -g

Step 8: Report completion

Provide a concise final report including:

• Installed vs already-present tools (brew, node, npm, npx, uv, python)
• Skills installed successfully
• Any blockers that remain (for example, CLT still pending)
• Exact next command if one manual action is still needed

Troubleshooting quick guide

• npx: command not found: ensure Node is installed and ~/.local/bin is on PATH.
• Failed to clone repository with xcode-select message: complete CLT install or use zipball fallback.
• Homebrew installer asks for sudo/admin: switch to user-local Node path when admin access is unavailable.
• Agents: not linked in npx skills list -g: installation succeeded; linking depends on host agent runtime.
