What
Claude Code wraps some of what it shows the model in reminder notes marked with special tags. When a file you changed or Claude read contains a closing reminder tag, Claude Code now replaces the opening < of that tag with < before showing the file. It also tells the model that the file "is not shown exactly as it is on disk". Before, file contents were inserted as they were.
Why
Text inside a file can no longer end a reminder note early and pass itself off as part of Claude Code's own instructions.
