What probably matters to youSection of the release
What
Claude Code ships with a built-in skill (a bundle of instructions and reference pages Claude can read when a task calls for it) about building with the Claude API. Its reference now includes a page, shared/message-threads.md, about message threads.
Why
When you ask Claude for help with code that uses the Claude API, its built-in guidance now covers message threads too.
