It can now add a second note under some conditions, separated from the first by a blank line. Before, only one note was added.\n\n**Why**\n\nClaude may get an extra hint after some failed commands, which can change how it responds to the failure.\n\n- Area: Bash Tool\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
