What
Claude Code groups shell commands that only read, search or list files into a collapsed summary on screen. A command that would normally count, but also contains <<, is no longer put in that group. << starts a heredoc, a block of text written inline and passed to a command.
Why
A heredoc can feed text to a command, so such a command might do more than read. It is now shown on its own instead of folded into the summary.
