# 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
```

3. Create/attach a session:

```bash
playwriter session new
```

4. 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());"
```

2. Collect page structure when needed:

```bash
playwriter -s <session> -e "console.log(await accessibilitySnapshot({ page }))"
```

3. Execute targeted actions (click/type/hover/fetch/evaluate).
4. Pull logs and structured state via `page.evaluate`.
5. 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.
