  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 1 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by brianlovin on GitHub. Read the source before you install it.

Installation

Install the Playwriter AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/brianlovin/agent-config.git /tmp/agent-config
mkdir -p .claude/skills
cp -r /tmp/agent-config/skills/playwriter .claude/skills/playwriter
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Playwriter in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Playwriter on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Playwriter is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Playwriter

Use this skill to drive the user's active Chrome tab via Playwriter.

Full documentation is available here: https://playwriter.dev/

Quick Start

  1. Ensure the Playwriter extension is enabled (green) on the target tab.
  2. Ensure CLI is available:
bash
playwriter --version || npx -y playwriter --version
  1. Create/attach a session:
bash
playwriter session new
  1. Run commands against that session:
bash
playwriter -s 1 -e "console.log(await page.url())"

Core Workflow

  1. Confirm connection and correct tab:
bash
playwriter -s <session> -e "console.log(await page.url()); console.log(await page.title());"
  1. Collect page structure when needed:
bash
playwriter -s <session> -e "console.log(await accessibilitySnapshot({ page }))"
  1. Execute targeted actions (click/type/hover/fetch/evaluate).
  2. Pull logs and structured state via page.evaluate.
  3. Summarize findings with exact IDs, timestamps, and observed state transitions.

Useful Commands

Get list rows/options from current app UI:

bash
playwriter -s <session> -e "const rows = await page.getByRole('option').all(); console.log(rows.length);"

Read popup/hover content:

bash
playwriter -s <session> -e "const row = page.getByRole('option').nth(0); await row.hover(); await page.waitForTimeout(700); console.log(await page.locator('[data-side]').first().innerText());"

Run arbitrary in-page debug code:

bash
playwriter -s <session> -e "const out = await page.evaluate(() => ({ href: location.href })); console.log(out);"

Troubleshooting

  • If the session attaches to the wrong tab, click the extension icon on the intended tab and re-run playwriter session new.
  • If playwriter command is missing, use npx -y playwriter ... or install globally.
  • If execution errors suggest stale connection, create a fresh session.

Guardrails

  • Prefer read-only inspection unless the task requires mutation.
  • Announce destructive UI actions before running them.
  • When capturing logs, redact sensitive tokens/user data in summaries.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Playwriter AI skill do?

Control the user's currently open Chrome tab through the Playwriter CLI (no new browser launch). Use when you need to inspect live UI state, run scripted browser actions, capture console output, or reproduce frontend issues directly in the user's tab.

Why use Playwriter on TypingMind?

Because you install it once and use it with any model. Playwriter is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Playwriter in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/brianlovin/agent-config/tree/main/skills/playwriter. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Playwriter?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Playwriter?

As many as you like. As long as a model supports skills, you can use Playwriter with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Playwriter AI skill free?

It is published on GitHub by brianlovin. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
