## What's changed
- Added Claude Mods: plugins may now modify deeper behavior
- 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)
- Added an `n:<text>` filter to the agents view that matches session names and tasks; a filter now shows matches in collapsed sections and Enter opens the first match
- Added `prompt_text` to the OpenTelemetry `user_prompt` event, a copy of `prompt` for backends that nest dotted keys; drop or mask it wherever you drop or mask `prompt` (anthropics/claude-code#70763)
- Added URL prompts from MCP servers on the 2025-11-25 protocol, for example to sign in. If a server no longer connects after this update, add "bareElicitationCapability": true to its MCP config entry
- Windows: Added a startup warning when denying the Bash tool also turns off the PowerShell tool, so Claude has no shell tool
- Self-hosted runner: Added a built-in `gh api` (REST only) for sessions that use Anthropic-managed git on macOS and Linux machines where the GitHub CLI is not installed
- Fixed fast mode staying off in remote sessions owned by an agent with no user account, even when the organization allows it
- Fixed Remote Control not receiving messages for minutes at a time when a reconnect request got no response; it now gives up after 30 seconds and retries
- Fixed hooks configured with `asyncRewake` waking Claude over and over with "found issues" notifications when the hook's script file is missing; the broken hook is now reported once
- Fixed tool heartbeats not reaching SDK hosts while the model's respons
