For writes the check always runs. For reads it runs only under a certain condition. If the check matches, Claude Code gives its answer at that point.\n\n**Why**\n\nThis could change which file paths ask you for permission or are refused.\n\n- Area: Permissions\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5"}
