What

When Claude Code decides whether to collapse a stretch of transcript into a summarized entry, and what that summary reports, it no longer takes REPL (read-eval-print loop, i.e. code execution) activity into account. Only search count and read count now factor into the decision and the resulting summary.

Why

This changes what causes a transcript to be summarized and what a collapsed summary mentions, so REPL activity alone will no longer trigger or appear in these condensed summaries.
