+# Contributing
+
+## Choose an issue
+
+Playwright MCP **requires an issue** for every contribution, except for minor documentation updates.
+
+If you are passionate about a bug/feature, but cannot find an issue describing it, **file an issue first**. This will
+facilitate the discussion, and you might get some early feedback from project maintainers before spending your time on
+creating a pull request.
+
+## Make a change
+
+> [!WARNING]
+> The core of the Playwright MCP was moved to the [Playwright monorepo](https://github.com/microsoft/playwright).
+
+Clone the Playwright repository. If you plan to send a pull request, it might be better to [fork the repository](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo) first.
+
+
+```bash
+git clone https://github.com/microsoft/playwright
+cd playwright
+```
+
+Install dependencies and run the build in watch mode.
+```bash
+# install deps and run watch
+npm ci
+npm run watch
+npx playwright install
+```
+
+Source code for Playwright MCP is located at [packages/playwright/src/mcp](https://github.com/microsoft/playwright/blob/main/packages/playwright/src/mcp).
+
+```bash
+# list source files
+ls -la packages/playwright/src/mcp
+```
+
+Coding style is fully defined in [eslint.config.mjs](https://github.com/microsoft/playwright/blob/main/eslint.config.mjs). Before creating a pull request, or at any moment during development, run linter to check all kinds of things:
+```bash
+# lint the source base before sending PR
+npm run flint
+```
+
+Comments should have an explicit purpose and should improve readability rather than hinder it. If the code would not be understood without comments, consider re-writing the code to make it self-explanatory.
+
+## Add a test
+
+Playwright requires a test for the new or modified functionality. An exception would be a pure refactoring, but chances are you are doing more than that.
+
+There are multiple [test suites](https://github.com/microsoft/playwright/blob/main/tests) in Playwright that will be executed on the CI. Tests for Playwright MCP are located at [tests/mcp](https://github.com/microsoft/playwright/blob/main/tests/mcp).
+
+```bash
+# list test files
+ls -la tests/mcp
+```
+
+To run the mcp tests, use
+
+```bash
+# fast path runs all MCP tests in Chromium
+npm run mcp-ctest
+```
+
+```bash
+# slow path runs all tests in three browsers
+npm run mcp-test
+```
+
+Since Playwright tests are using Playwright under the hood, everything from our documentation applies, for example [this guide on running and debugging tests](https://playwright.dev/docs/running-tests#running-tests).
+
+Note that tests should be *hermetic*, and not depend on external services. Tests should work on all three platforms: macOS, Linux and Windows.
+
+## Write a commit message
+
+Commit messages should follow the [Semantic Commit Messages](https://www.conventionalcommits.org/en/v1.0.0/) format:
+
+```
+label(namespace): title
+
+description
+
+footer
+```
+
+1. *label* is one of the following:
+    - `fix` - bug fixes
+    - `feat` - new features
+    - `docs` - documentation-only changes
+    - `test` - test-only changes
+    - `devops` - changes to the CI or build
+    - `chore` - everything that doesn't fall under previous categories
+2. *namespace* is put in parentheses after label and is optional. Must be lowercase.
+3. *title* is a brief summary of changes.
+4. *description* is **optional**, new-line separated from title and is in present tense.
+5. *footer* is **optional**, new-line separated from *description* and contains "fixes" / "references" attribution to GitHub issues.
+
+Example:
+
+```
+feat(trace viewer): network panel filtering
+
+This patch adds a filtering toolbar to the network panel.
+<link to a screenshot>
+
+Fixes #123, references #234.
+```
+
+## Send a pull request
+
+All submissions, including submissions by project members, require review. We use GitHub pull requests for this purpose.
+Make sure to keep your PR (diff) small and readable. If necessary, split your contribution into multiple PRs.
+Consult [GitHub Help](https://help.github.com/articles/about-pull-requests/) for more information on using pull requests.
+
+After a successful code review, one of the maintainers will merge your pull request. Congratulations!
+
+## More details
+
+**No new dependencies**
+
+There is a very high bar for new dependencies, including updating to a new version of an existing dependency. We recommend to explicitly discuss this in an issue and get a green light from a maintainer, before creating a pull request that updates dependencies.
+
+## Contributor License Agreement
+
+This project welcomes contributions and suggestions.  Most contributions require you to agree to a
+Contributor License Agreement (CLA) declaring that you have the right to, and actually do, grant us
+the rights to use your contribution. For details, visit https://cla.opensource.microsoft.com.
+
+When you submit a pull request, a CLA bot will automatically determine whether you need to provide
+a CLA and decorate the PR appropriately (e.g., status check, comment). Simply follow the instructions
+provided by the bot. You will only need to do this once across all repos using our CLA.
+
+### Code of Conduct
+
+This project has adopted the [Microsoft Open Source Code of Conduct](https://opensource.microsoft.com/codeofconduct/).
+For more information see the [Code of Conduct FAQ](https://opensource.microsoft.com/codeofconduct/faq/) or

-# Examples
-
-Below are some examples of prompts to use with Playwright MCP. Draw inspiration from them to create your own. If you come up with a new prompt that works well, feel free to let us know in an issue or pull request.
-
-## Write a regression test for a bug report
-
-We have received a user report about a bug on our website https://debs-obrien.github.io/playwright-movies-app. I'd like you to verify if this bug exists by trying to follow the steps. If you see different behaviour, explain how it's different. If you see the same behaviour, please write me a Playwright regression test that encapsulates the buggy user flow. While writing the test, draw inspiration from the Playwright code you ran. Here's the user report:
-
-Howdy. I love your movies site, but there's something fishy going on. I'm looking at The Garfield Movie - a spectacular film - but somehow it's showing the wrong length. The movie is 90mins long, I measured myself yesterday! But somehow your site is claiming 101mins. Am I looking at it wrong, or is there a bug?
-
-**Output:**
-
-```ts
-import { test, expect } from '@playwright/test';
-
-/**
- * Regression test for bug: The Garfield Movie showing incorrect runtime
- * User reported actual runtime is 90 minutes, but site shows 101 minutes
- */
-test('verify The Garfield Movie runtime bug', async ({ page }) => {
-  // Navigate to the movies app home page
-  await page.goto('https://debs-obrien.github.io/playwright-movies-app');
-  
-  // Wait for page to load completely
-  await expect(page.getByRole('heading', { name: 'Popular', level: 1 })).toBeVisible();
-  
-  // Look for The Garfield Movie and click on it
-  const garfieldMovieLink = page.getByRole('link', { name: /poster of The Garfield Movie/i });
-  await expect(garfieldMovieLink).toBeVisible();
-  await garfieldMovieLink.click();
-  
-  // Verify we're on the correct movie page
-  await expect(page.getByRole('heading', { name: 'The Garfield Movie', level: 1 })).toBeVisible();
-  
-  // Check the runtime information
-  // The bug: Expected runtime should be 90 min, but site shows 101 min
-  const movieInfoText = await page.locator('text=English / 101 min. / 2024').textContent();
-  
-  // This test will fail because of the bug (which is what we want to demonstrate)
-  // Once fixed, this assertion should be updated to the correct runtime (90 min)
-  expect(movieInfoText).toContain('90 min');
-  
-  // Alternative assertion that verifies the incorrect runtime is still present
-  // Uncomment this and comment the above assertion to verify the bug exists
-  // expect(movieInfoText).toContain('101 min');

+# Playwright MCP Chrome Extension
+
+## Introduction
+
+The Playwright MCP Chrome Extension allows you to connect to pages in your existing browser and leverage the state of your default user profile. This means the AI assistant can interact with websites where you're already logged in, using your existing cookies, sessions, and browser state, providing a seamless experience without requiring separate authentication or setup.
+
+## Prerequisites
+
+- Chrome/Edge/Chromium browser
+
+## Installation Steps
+
+### Download the Extension
+
+Download the latest Chrome extension from GitHub:
+- **Download link**: https://github.com/microsoft/playwright-mcp/releases
+
+### Load Chrome Extension
+
+1. Open Chrome and navigate to `chrome://extensions/`
+2. Enable "Developer mode" (toggle in the top right corner)
+3. Click "Load unpacked" and select the extension directory
+
+### Configure Playwright MCP server
+
+Configure Playwright MCP server to connect to the browser using the extension by passing the `--extension` option when running the MCP server:
+
+```json
+{
+  "mcpServers": {
+    "playwright-extension": {
+      "command": "npx",
+      "args": [
+        "@playwright/mcp@latest",
+        "--extension"
+      ]
+    }
+  }
+}
+```
+
+## Usage
+
+### Browser Tab Selection
+
+When the LLM interacts with the browser for the first time, it will load a page where you can select which browser tab the LLM will connect to. This allows you to control which specific page the AI assistant will interact with during the session.
+
+### Bypassing the Connection Approval Dialog
+
+By default, you'll need to approve each connection when the MCP server tries to connect to your browser. To bypass this approval dialog and allow automatic connections, you can use an authentication token.
+
+#### Using Your Unique Authentication Token
+
+1. After installing the extension, click on the extension icon or navigate to the extension's status page
+2. Copy the `PLAYWRIGHT_MCP_EXTENSION_TOKEN` value displayed in the extension UI
+3. Add it to your MCP server configuration:
+
+```json
+{
+  "mcpServers": {
+    "playwright-extension": {
+      "command": "npx",
+      "args": [
+        "@playwright/mcp@latest",
+        "--extension"
+      ],
+      "env": {
+        "PLAYWRIGHT_MCP_EXTENSION_TOKEN": "your-token-here"
+      }
+    }
+  }
+}
+```
+
+This token is unique to your browser profile and provides secure authentication between the MCP server and the extension. Once configured, you won't need to manually approve connections each time.

+Playwright CLI with SKILLS
+
+### Playwright CLI vs Playwright MCP
+
+This package provides CLI interface into Playwright. If you are using **coding agents**, that is the best fit.
+
+- **CLI**: Modern **coding agents** increasingly favor CLI–based workflows exposed as SKILLs over MCP because CLI invocations are more token-efficient: they avoid loading large tool schemas and verbose accessibility trees into the model context, allowing agents to act through concise, purpose-built commands. This makes CLI + SKILLs better suited for high-throughput coding agents that must balance browser automation with large codebases, tests, and reasoning within limited context windows.
+
+- **MCP**: MCP remains relevant for specialized agentic loops that benefit from persistent state, rich introspection, and iterative reasoning over page structure, such as exploratory automation, self-healing tests, or long-running autonomous workflows where maintaining continuous browser context outweighs token cost concerns. Learn more about [Playwright MCP](https://github.com/microsoft/playwright-mcp).
+
+### Key Features
+
+- **Token-efficient**. Does not force page data into LLM.
+
+### Requirements
+- Node.js 18 or newer
+- Claude Code, GitHub Copilot, or any other coding agent.
+
+## Getting Started
+
+## Installation
+
+```bash
+npm install -g @playwright/cli@latest
+playwright-cli --help
+```
+
+## Demo
+
+```
+> Use playwright skills to test https://demo.playwright.dev/todomvc/.
+  Take screenshots for all successful and failing scenarios. 
+```
+
+Your agent will be running commands, but it does not mean you can't play with it manually:
+
+```
+playwright-cli open https://demo.playwright.dev/todomvc/ --headed
+playwright-cli type "Buy groceries"
+playwright-cli press Enter
+playwright-cli type "Water flowers"
+playwright-cli press Enter
+playwright-cli check e21
+playwright-cli check e35
+playwright-cli screenshot
+```
+
+### Skills-less operation
+
+Point your agent at the CLI and let it cook. It'll read the skill off `playwright-cli --help` on its own:
+
+```
+Test the "add todo" flow on https://demo.playwright.dev/todomvc using playwright-cli.
+Check playwright-cli --help for available commands.
+```
+
+### Installing skills
+
+Claude Code, GitHub copilot and others will let you install the Playwright skills into the agentic loop.
+
+#### plugin (recommended)
+```bash
+/plugin marketplace add microsoft/playwright-cli
+/plugin install playwright-cli
+```
+
+#### manual
+
+```bash
+mkdir -p .claude/skills/playwright-cli
+curl -o .claude/skills/playwright-cli/SKILL.md \
+  https://raw.githubusercontent.com/microsoft/playwright-cli/main/skills/playwright-cli/SKILL.md
+```
+
+## Headed operation
+
+Playwright CLI is headless by default. If you'd like to see the browser, pass `--headed` to `open`:
+
+```bash
+playwright-cli open https://playwright.dev --headed
+```
+
+## Sessions
+
+Playwright CLI will use a dedicated persistent profile by default. It means that
+your cookies and other storage state will be preserved between the calls. You can use different
+instances of the browser for different projects with sessions.
+
+Following will result in two browsers with separate profiles being available. Pass `--session` to
+the invocation to talk to a specific browser.
+
+```bash
+playwright-cli open https://playwright.dev
+playwright-cli --session=example open https://example.com
+playwright-cli session-list
+```
+
+You can run your coding agent with the `PLAYWRIGHT_CLI_SESSION` environment variable:
+
+```bash
+PLAYWRIGHT_CLI_SESSION=todo-app claude .
+```
+
+Or instruct it to prepend `--session` to the calls.
+
+Manage your sessions as follows:
+
+```bash
+playwright-cli session-list             # list all sessions
+playwright-cli session-stop [name]      # stop session
+playwright-cli session-stop-all         # stop all sessions
+playwright-cli session-delete [name]    # delete session data along with the profiles
+```
