TL;DR: Anthropic shipped a built-in Claude Code plugin that scans Claude's output and flags important details developers might otherwise miss.
Summary: The Claude Devs team announced a new built-in plugin for Claude Code called 'You should know,' which scans Claude's output for important information and surfaces it to keep users in the loop. It can be enabled directly from the CLI with the command /plugin enable cc-plugin-you-should-know@builtin, making it a first-party addition rather than a third-party extension.
Why it matters: Long agentic coding sessions often bury critical warnings, assumptions, or breaking changes in walls of output, so an automatic high-signal scanner reduces silent mistakes. Worth enabling on any project running multi-step Claude Code tasks and watching whether the signal-to-noise ratio holds in practice.
