# Tap

Tap lets an agent perform tasks in your signed-in Chrome and save the interaction as a replayable flow. Use it for pages that require a login.

## What it does

Tap connects an agent to a Chrome session that is already signed in. The agent inspects a page once and produces a `.flow.json` program; later runs replay that program without another LLM call. Execution can use the Chrome extension or Playwright.

The server includes `tap verify`, which compares a page snapshot and reports changes that may break a saved flow. Open pages and APIs can run without the extension, while `--no-extension` uses a separate Playwright profile. The Chrome extension is required when Tap must reuse a live signed-in session, so its cookies and login remain available to the browser action.

## When to use it
- perform an action on a login-gated page
- save browser steps as a `.flow.json` program
- replay a flow without another LLM call
- check a page for changes with `tap verify`

## Example prompts
- Open the signed-in site and perform the action I need to repeat.
- Save this browser process as a replayable flow.
- Run `tap verify` on the saved flow and show what changed.
