Unclear It is not clear from this alone what switches the plugin on or what it shows through these hooks.

What

A new built-in plugin, cc-plugin-you-should-know, ships with Claude Code. A plugin is an add-on that extends Claude Code. While Claude works, a side agent (a separate helper running alongside the main conversation) may offer one learning topic above the prompt box.

  • The suggestion offers choices such as Learn more, Knew this already and Dismiss. Learn more can produce an explanation or a private learning page.
  • The plugin is registered with defaultEnabled: !1, meaning it is off until you turn it on.
  • It is not registered when Claude Code runs with the local-agent entrypoint.
  • An availability check leaves out HIPAA, ZDR and LDR accounts and also checks one more gate.
  • It hooks into prompt.submit, command.run, turn.step, ui.render and session.detach, the points where you send a prompt, run a command, Claude takes a step, the screen is drawn and a session is detached.
  • It reads the environment variables CLAUDE_CODE_YOU_SHOULD_KNOW_DEBUG and USER_TYPE, and keeps an aboutOpen state value. Setting CLAUDE_CODE_YOU_SHOULD_KNOW_DEBUG shows a debug row for each check.
  • /plugin disable cc-plugin-you-should-know@builtin turns it off.

Why

This is a complete feature with its own prompt, but it stays off unless enabled and depends on account type and a gate. If you do turn it on and find the suggestions distracting, /plugin disable cc-plugin-you-should-know@builtin removes them.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Added since A small documentation edit on Mods overview touched a line naming cc-plugin-you-should-know after this was published. | `cc-plugin-you-should-know` | Runs a side agent that watches your back while Claude works on longer tasks. When it finds something worth knowing that you might miss, it shows you a note above the prompt. | Disabled by default. Listed in … plugins/mods/overview see the edit
Confirmed since Anthropic's documentation has since written up cc-plugin-you-should-know, on Claude Code changelog. * Added You should know, an opt-in plugin where a side agent watches your back and flags things you or Claude might miss. Turn it on with `/plugin enable cc-plugin-you-should-know@builtin` (for first-party sessions with telemetry on) changelog see the edit
