Compacting means replacing older messages with a summary so there is room to keep working. The instructions it uses to write that summary now accept an extra option. When the option is set, a further piece of text is added after the base instruction. If you have supplied your own summary prompt, the base instruction inside it is swapped as well.\n\n**Why**\n\nThis can change what ends up in the summaries Claude Code writes when it compacts a conversation.\n\n- Area: Compaction\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
