pi-playwright

Playwright browser automation skill package for pi.

It adds the playwright-browser skill so pi can open pages, inspect the DOM, click, fill forms, capture screenshots, watch console/network output, and save auth state through the local @playwright/cli.

CLI-first. Token-efficient. Built for coding agents.

Included skill

• playwright-browser — browser automation via @playwright/cli

Why

This package keeps browser automation simple and inspectable:

• local CLI execution instead of a large remote tool surface
• project-scoped browser sessions
• artifact-friendly workflows for screenshots, PDFs, and snapshots
• minimal context overhead for coding agents

Install

Install into pi

pi install npm:pi-playwright

To install only for the current project:

pi install -l npm:pi-playwright

Pi installs the package dependencies automatically.

If your machine does not already have a compatible browser available, install Chromium once:

npx playwright install chromium

Add to pi config

Global config (~/.pi/agent/settings.json):

{
  "packages": ["pi-playwright"]
}

Explicit npm source:

{
  "packages": ["npm:pi-playwright"]
}

If you want to pin a specific release, use npm:pi-playwright@<version>.

Project-local config (.pi/settings.json) works the same way.

Usage

Ask pi to use the skill naturally, or force it explicitly:

/skill:playwright-browser

Example prompts:

• Use the playwright browser skill to test http://localhost:3000 login flow.
• Open the app in a browser, take a full-page screenshot, and inspect console errors.
• Use playwright-browser to fill the signup form and save auth state.

What the skill provides

Wrapper scripts live in skills/playwright-browser/scripts/:

• pw.js — local playwright-cli wrapper with auto session selection
• artifact-dir.js — prints a stable artifact directory for the current session
• detect-dev-servers.js — probes common localhost dev server URLs

Default behavior:

• session derived from the current git repo or cwd
• artifacts stored under /tmp/pi-playwright/<session>/
• uses the package-local Playwright CLI dependency

Override the session explicitly if needed:

PLAYWRIGHT_CLI_SESSION=my-session node skills/playwright-browser/scripts/pw.js open https://example.com
