# Playwright Browser Automation

Write and execute focused Playwright scripts for the user's request. Prefer the
skill's executor and helpers, but use the full Playwright API when needed.

## Path resolution

This skill can be installed in several locations, so resolve its directory
first. Set `SKILL_DIR` to the directory containing this SKILL.md file, then run
the commands below as written:

```bash
export SKILL_DIR=<absolute path of the directory containing this SKILL.md>
export TMP_DIR="$(node -p 'require("node:os").tmpdir()')"
```

If shell state does not persist between commands, substitute the literal paths
for `$SKILL_DIR` and `$TMP_DIR` in each command instead.

Common installation paths:

- Plugin system: `~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill`
- Manual global: `~/.claude/skills/playwright-skill`
- Project-specific: `<project>/.claude/skills/playwright-skill`

## Workflow

1. For localhost work, detect running servers before writing a URL:

   ```bash
   node -e "require('$SKILL_DIR/lib/helpers').detectDevServers().then(s => console.log(JSON.stringify(s)))"
   ```

   Use the only result automatically. Ask which URL to use when there are
   multiple results. Ask for a URL or offer to start a server when none exist.
2. Write reusable scripts to `$TMP_DIR/playwright-test-*.js` unless the user
   asks to save them in the project. Use `PW_SCRIPT_DIR` to preserve scripts.
3. Use a visible browser by default. Use `headless: true` only when requested
   or when the environment has no display.
4. Put the target URL in a constant or environment variable.
5. Run scripts with `node "$SKILL_DIR/run.js" <script.js>`.
6. Report actions, failures, and artifact paths. Do not claim success without
   checking the resulting page.

## Setup

Run once:

```bash
