#### Playwright Agents

Introducing Playwright Agents, three custom agent definitions designed
to guide LLMs through the core process of building a Playwright test:

- **🎭 planner** explores the app and produces a Markdown test plan
- **🎭 generator** transforms the Markdown plan into the Playwright Test
files
- **🎭 healer** executes the test suite and automatically repairs failing
tests

Run `npx playwright init-agents` with your client of choice to generate
the latest agent definitions:

```bash

### Generate agent files for each agentic loop
### Visual Studio Code
npx playwright init-agents --loop=vscode

### Claude Code
npx playwright init-agents --loop=claude

### opencode
npx playwright init-agents --loop=opencode
```

> \[!NOTE]
> VS Code v1.105 (currently on the VS Code Insiders channel) is needed
for the agentic experience in VS Code. It will become stable shortly, we
are a bit ahead of times with this functionality!

Agents](https://playwright.dev/docs/test-agents)

#### New APIs

- New methods
[page.consoleMessages()](https://playwright.dev/docs/api/class-page#page-console-messages)
and
[page.pageErrors()](https://playwright.dev/docs/api/class-page#page-page-errors)
for retrieving the most recent console messages from the page
- New method
[page.requests()](https://playwright.dev/docs/api/class-page#page-requests)
for retrieving the most recent network requests from the page
- Added [`--test-list` and
`--test-list-invert`](https://playwright.dev/docs/test-cli#test-list) to
allow manual specification of specific tests from a file

#### UI Mode and HTML Reporter

- Added option to `'html'` reporter to disable the "Copy prompt" button
- Added option to `'html'` reporter and UI Mode to merge files,
collapsing test and describe blocks into a single unified list

will return an empty list

#### Miscellaneous

- Aria snapshots render and compare `input` `placeholder`
- Added environment variable `PLAYWRIGHT_TEST` to Playwright worker
processes to allow discriminating on testing status
