When Claude Code loads these transcripts for a session, it now starts reading all of them at once. Before, the work went through a helper that limited how many ran together.\n\nIf one transcript fails to load, it is still skipped and the others carry on.\n\n**Why**\n\nIn a session that used many subagents, Claude Code now opens many files at the same moment. That can be faster, but it uses more resources in one burst.\n\n- Area: Elsewhere\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
