Claude Code changed how it treats a reply in which Claude made several calls to the same tool at once. If no thinking block follows those calls and every one of them succeeded, Claude Code removes the duplicate calls and their results and keeps only the first.\n\nThis step only runs when an internal condition allows it.\n\n**Why**\n\nThis can change what the conversation history sent to the model contains.\n\n- Area: Context Management\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
