Types of add-ons

Plugins: Bundles of skills, commands, agents, hooks, MCP servers, and mods
MCP servers: Give Claude tools to reach outside systems
Skills: Saved instructions Claude uses when relevant
Mods: Code that changes how Claude Code looks and behaves
Hooks: Scripts that run on events, such as after an edit

Add what removes real friction. Every add-on costs a little context and trust.

29 · Token Weather: a sample mod that shows context usage
30 · Blast Radius: a sample mod that holds risky commands

Mods need Claude Code v2.1.287 or later in the terminal. They are not sandboxed, so install only from sources you trust.

Hooks and status lines

31 · A format-on-edit hook that runs your formatter after every change
32 · A notification hook that alerts you when Claude needs input
33 · A custom status line showing model, branch, and context

Editors and GitHub

34 · The VS Code extension
35 · The JetBrains plugin

The Claude GitHub app adds Claude to pull requests and issues. Check what GitHub usage it needs before turning on automations.

How to install

Run /plugin to browse and install plugins and mods
Run claude mcp add or use /mcp for MCP servers
Put skills in your project’s .claude/skills folder or install them in a plugin
Configure hooks and the status line in your settings

Keep it lean and safe

Start with three to five add-ons
Remove what you have not used in a month
Check /context to see what uses space
Read the code of third-party plugins and mods
Never store API keys in plugin files

The golden rule

Do not install all 35. Pick the few that fit your daily work, and remove anything that does not earn its place.

Plugins
MCP
Skills
Mods
Hooks
Editors
Lean

Install one plugin, one MCP server, and one skill that match your current project, and use them for a week.
