Use when the task requires automating a real browser from the terminal (navigation, form filling, snapshots, screenshots, data extraction, UI-flow debugging) via `playwright-cli` or the bundled wrapper script.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Playwright CLI Skill
Drive a real browser from the terminal using `playwright-cli`. Prefer the bundled wrapper script so the CLI works even when it is not globally installed.
Treat this skill as CLI-first automation. Do not pivot to `@playwright/test` unless the user explicitly asks for test files.
## Prerequisite check (required)
Before proposing commands, check whether `npx` is available (the wrapper depends on it):
```bash
command -v npx >/dev/null 2>&1
```
If it is not available, pause and ask the user to install Node.js/npm (which provides `npx`). Provide these steps verbatim:
```bash
# Verify Node/npm are installed
node --version
npm --version
# If missing, install Node.js/npm, then:
npm install -g @playwright/cli@latest
playwright-cli --help
```
Once `npx` is present, proceed with the wrapper script. A global install of `playwright-cli` is optional.
## Skill path (set once)
```bash
# Set SKILL_DIR to the directory containing this SKILL.md
export PWCLI="<path-to-skill>/scripts/playwright_cli.sh"
```
Replace `<path-to-skill>` with the actual skill installation directory (e.g. `.skills/playwright` or `~/.letta/skills/playwright`).
## Quick start

The line at the top of this page pins the label git:20260422.d32735f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
