Changelog #024

Hey everyone! Quiet week. Two things landed worth flagging.

We added deep research examples to the cookbook — full agent workflows you can fork and run. And the Files API docs got a long-overdue scrub: a few of the example endpoints and SDK calls were just wrong.

⭐ New

• Deep research with Claude Agent SDK subagents in the cookbook — a lead orchestrator dispatches parallel researcher subagents, each driving its own Steel browser, and synthesizes findings into a cited Markdown report. Source on GitHub: TS · Python.

🔧 Improvements

• Hermesforge Screenshot API added to awesome-web-agents.

🐛 Bug Fixes

• Files API docs corrections. Upload endpoints don't have a /upload suffix — it's POST /v1/sessions/{id}/files and POST /v1/files. Session archive is GET /v1/sessions/{id}/files.zip. List responses come back as { data: [...] }. The SDK method is client.sessions.files.downloadArchive(...), and global file uploads return path, not id. If the old examples sent you to a 404, sorry about that.
