Installation

Why local installation

Claude Code running on your machine gives you capabilities unavailable in the browser:

• Edit files in your repository directly
• Run tests, linters, and build tools
• Connect to local MCP servers (databases, APIs, internal tools)
• Use shell commands and scripts
• Install and use Agronod plugins for team workflows

If you want Claude working in your terminal and your repo, you need local installation.

Prerequisites

Before installing Claude Code, ensure you have:

• macOS or Linux (Windows support via WSL)
• Node.js 18+ installed (download)
• A Claude.ai account with Claude Code access

Install Claude Code

Recommended (installer script):

curl -fsSL https://claude.ai/install.sh | bash

Homebrew (macOS):

brew install --cask claude-code

npm (fallback — requires Node 18+):

npm install -g @anthropic-ai/claude-code

Verify Installation

# Launch Claude Code
claude

# Check version
claude --version

If you see version output, you're ready. If not, see Troubleshooting below.

Add the Agronod marketplace (optional)

The Agronod marketplace provides curated plugins for team workflows. This is optional — Claude Code works without it.

In a Claude Code session, run:

/plugin marketplace add agronod/claude-plugins

The /plugin command manages plugins in Claude Code. You can list installed plugins with /plugin list and explore the marketplace with /plugin marketplace search.

See Agronod Plugins for details on available plugins.

Troubleshooting

"Command not found" after installation

• Add npm global bin to your PATH, or restart your terminal session.

Authentication fails

• Ensure you have Claude Code access on your account.
• Try claude, then /logout, then claude again.
