What probably matters to youSection of the release
Unclear Whether how the setting is enforced also changed, or only its description, is not clear.
What
Workflows are Claude Code's multi-step automated runs. Managed settings are settings an administrator puts on a machine that users cannot override. Claude Code now checks managed settings for disableWorkflows, or for CLAUDE_CODE_DISABLE_WORKFLOWS in their env block, and refuses to start a workflow when either is set.
Refusals now say why. One message covers workflows turned off by the machine's administrator, for example "Code review did not run: workflows are turned off in this machine's managed settings". Another covers managed settings that could not be read.
The setting's description now reads "Disable the Workflows feature." It adds that Code Review and /ultrareview run in the cloud and are not stopped by it.
The policy check now also takes into account where the session's event came from. It can skip resuming a launch that needs that information.
Why
Administrators get a central way to switch workflows off, and users get a message explaining why a launch was refused. Admins should know the limit: cloud-run Code Review and /ultrareview are not covered by this switch.
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 sinceA small documentation edit on Code Review touched a line naming /ultrareview after this was published.To run a cloud review from a script or CI job, use the [`claude ultrareview` subcommand](/docs/en/ultrareview#run-ultrareview-non-interactively), which waits for the findings and prints them to stdout.code-reviewsee the edit
Confirmed sinceAnthropic's documentation has since written up /ultrareview, on Claude Code changelog.* Removed the browser link from `/ultrareview` and `claude ultrareview` outputchangelogsee the edit
