3Install it

Add it to Claude Code

◆ Claude CodePaste one message into Claude Code and it installs itself. No terminal needed.
  1. 1

    Download and unzip

    Click Download above, then double-click the file you get.

  2. 2

    Paste one message to Claude

    The walkthrough below has the exact wording. Claude installs the kit for you.

  3. 3

    Say yes when it asks

    Claude asks before running anything on your computer. Approve it and the install is done.

  4. 4

    Type / to check

    The kit's commands appear in the list. Plain English works too.

Never installed a skill before? Follow the walkthrough below — the same steps, one click at a time, with pictures.

4Install walkthrough

Step by step, with pictures

First time installing a skill? You paste one message into Claude Code and it installs itself. No terminal, no folders to make, about a minute.

  1. 1

    Download the file

    Scroll up and click the rust Download .zip button. It saves to your Downloads folder.

    The Download .zip button on a skill page
  2. 2

    Unzip it

    Double-click the file you just downloaded. It turns into a folder called claude-code-setup-kit. Leave it in Downloads.

  3. 3

    Paste this into Claude Code

    Open Claude Code and paste this in, exactly as it is, then press enter:

    Install my Claude Code plugin by running these two shell commands for me:
    claude plugin marketplace add ~/Downloads/claude-code-setup-kit
    claude plugin install claude-code-setup-kit@boss-of-prompts

    If you unzipped somewhere other than Downloads, change that path to match. This works anywhere you use Claude Code — the terminal, the desktop app or your editor.

  4. 4

    Say yes when it asks

    Claude asks permission before running anything on your computer. That's the safety net working — approve it, and it does the install for you. You'll get a line back confirming the kit is installed.

    One thing to note: the plugin's skills and commands typically become active after Claude Code reloads its configuration. If you don't see the new commands or skills right away, restart Claude Code (quit and reopen) and they'll be picked up.

    Check it worked

    Type / and you'll see the kit's commands in the list, each starting with claude-code-setup-kit:. Better still, just say what you want — "set up a CLAUDE.md for my project" — and it starts itself.

    Claude confirming the plugin is installed
Prefer the terminal?2 lines

Same install, run yourself from a terminal instead of asking Claude.

claude plugin marketplace add ~/Downloads/claude-code-setup-kit
claude plugin install claude-code-setup-kit@boss-of-prompts

Not sure what a terminal is? Ignore this box completely — the steps above do exactly the same job.

You never have to type a command. "Set up a CLAUDE.md for my project", "start my session" and "it broke, undo this" all work — the right skill recognizes the job and starts itself. The commands are just the fast path.

5Run it

Once installed, just type

Set up my guardrails
Start my session
It broke — undo this
What just happened?

Plain English is the way to drive it — Guardian recognises the job and starts itself. Prefer commands? `/claude-code-setup-kit:guard`, `:kickoff` and `:recover` do the same jobs.

Why it works

Every incident becomes a short walk back to a save point. Fences make the next one rarer.

Tips

  • Set up the guardrails before your first real work session
  • Write your CLAUDE.md first, or there's nothing to fence
  • Say what broke in your own words
  • Accept the fence it offers after a recovery
  • Needs Claude Code and git, not claude.ai

How to use it

  • Unzip the download
  • Paste the install message into Claude Code
  • Say yes when Claude asks to run it
  • Say "set up my guardrails" once, on day one
  • Say "start my session" at the start of each session
  • Say "it broke — undo this" when something breaks
