Get Started with your PM OS — connect Claude Code in minutes

Connect Claude Code to mySecond so it knows your company, your users, and your competitors — and remembers them.

When to use this

  • You just signed up and want to start working
  • You're setting up on a new machine
  • You got disconnected and want to reconnect

Setup

  1. Make a folder for your PM work (call it "PMOS") and open it in Claude Code. On Desktop, open the folder from Claude Code. In a terminal, run cd pmos && claude. Tip: you can open your product's repo instead — skills can then read your code.
  2. Go to mysecond.ai/connect and copy the message shown there.
  3. Paste the message into Claude Code. It installs your PM OS on its own — about a minute.
  4. Approve the connection when Claude Code asks. A browser tab opens, and one click links your account. If you don't see the tab, check your other browser windows.
  5. Quit and reopen Claude Code so it loads mySecond.
  6. Run /welcome. Claude spends about five minutes learning your company, product, and personas.

How it works

The message you paste installs 70+ PM skills and links Claude Code to your mySecond account. /welcome then builds your five context files — company, product, personas, competitors, and goals. From then on, every skill uses your context. Your outputs sync to mySecond after each session, so you can read and edit them in the Files tab.
