## 📣 Playwright CLI+SKILLs 📣
We are adding a new token-efficient CLI mode of operation to Playwright with the skills located at [playwright-cli](https://github.com/microsoft/playwright-cli). This brings the long-awaited official SKILL-focused CLI mode to our story and makes it more coding agent-friendly.
> It is the first snapshot with the essential command set (which is already larger than the original MCP!), but we expect it to grow rapidly. Unlike the token use, that one we expect to go down since snapshots are no longer forced into the LLM!

Thanks to [@cpAdm](https://github.com/cpAdm) for contributing these improvements!
## Miscellaneous
[browserType.connectOverCDP()](https://playwright.dev/docs/api/class-browsertype#browser-type-connect-over-cdp) now accepts an `isLocal` option. When set to `true`, it tells Playwright that it runs on the same host as the CDP server, enabling file system optimizations.
