vercel-labs/agent-browser v0.42.0 on GitHub

Added saved flows (experimental): record a browser task once, then replay its requests. A run tries direct HTTP first, then the same request from the page, then a replay of the recorded commands, and saves the tier that worked. Runs send requests only to public addresses, and saving waits for in-flight requests and follows redirects to the end (#2236, #2397, #2432, #2433, #2444)
MCP tools now list only the shared arguments each tool uses (#2311)

Fixed session reuse and relaunch, now decided in one place in the daemon. A connection target is kept only after an attach succeeds, and security settings persist across daemon restarts (#2396, #2418, #2429)
Fixed Safari and iOS WebDriver sessions being dropped (#2385)
Fixed fill and type altering literal text, and mouse and element coordinates losing fractional values (#2394, #2393)
Fixed percent-encoded proxy credentials not being decoded (#2389)
Fixed downloads moving local files from an attached Chrome (#2392)
Fixed MCP tool results that repeated JSON stdout (#2390)
Fixed unknown commands and cookie operations, now rejected, and misplaced global options in batch commands (#2383, #2386)
Fixed errors output to print page error text, and labeled storage clear as storage rather than the request log (#2427, #2428)
Fixed macOS Chrome discovery for apps installed in the user's Applications folder (#2388)
Fixed Windows recording opening ffmpeg console windows (#2382)
Skipped a repeat Browser.getVersion call after the outdated-browser check (#2420)

The core skill now tells agents to prefer snapshots: screenshot only when asked or for content the DOM cannot represent, and wait and snapshot again when an expected element is missing (#2453, #2461)
The package now declares a Node 22 minimum and drops engines.pnpm (#2404)
Docs and dashboard chat use openai/gpt-6-luna-fast (#2440)
Upgraded the repository to TypeScript 7
