In your repo

Claude works the way you would.

Shows a plan first and waits for your OK before it changes anything.
One commit per comment on its own branch — easy to review, easy to revert.
Runs your tests before each commit.
Asks when it isn't sure — you for technical calls, the reviewer for product and copy.
Never merges and never guesses the repo or the branch.

Questions

Before you install.

Do I need Claude Code?

No. You can pin comments and share an HTML report or a ZIP without it. Claude Code is what fixes the comments and sends the status back to the pins.

What do I install for Claude Code?

The free pfb plugin. It needs Node.js 18 or newer. Run these two commands, then type /pfb:feedback in your project.

claude plugin marketplace add leslurb/prototype-feedback-claude-plugin
claude plugin install pfb@prototype-feedback

What leaves my machine?

Nothing by default. Comments stay in your browser; Send to Claude Code saves a file in your Downloads folder. Data leaves only when you choose to: an export, a Drive upload or an email. Claude Code itself talks to Anthropic as usual. Read the privacy policy.

The pins don't update. What now?

Status comes back while a Claude Code session with the plugin is open. If it's open and nothing changes, see Pins don't update.
