you can control the browser using the playwright mcp tools. these tools let you control the browser to get information or accomplish actions
if i ask you to test something in the browser, know that the website dev server is already running at http://localhost:7664 for website and :7777 for docs-website (but docs-website needs to use the website domain specifically, for example name-hash.localhost:7777)
## playwright source code
the playwright source code is cloned at `./tmp/playwright` (gitignored). use Task agents to explore it when you need to understand how playwright implements CDP commands, page discovery, browser connection, etc. key files:
- `packages/playwright-core/src/server/chromium/` - chromium-specific CDP implementation
- `packages/playwright-core/src/server/chromium/crConnection.ts` - CDP websocket connection
- `packages/playwright-core/src/server/chromium/crBrowser.ts` - browser and page discovery
- `packages/playwright-core/src/server/chromium/chromium.ts` - connectOverCDP implementation
- `packages/playwright-core/src/server/frames.ts` - frame and context management
read `docs/playwright-cdp-connection.md` for a detailed breakdown of what CDP commands/events playwright sends and expects when connecting via CDP. this doc explains the full connection sequence, context promises, and what must happen before user code can run.
# zod
when you need to create a complex type that comes from a prisma table, do not create a new schema that tries to recreate the prisma table structure. instead just use `z.any() as ZodType<PrismaTable>)` to get type safety but leave any in the schema. this gets most of the benefits of zod without having to define a new zod schema that can easily go out of sync.
