When that request arrives from the API cut short, Claude Code now logs a dedicated error starting \"API tool-call block cut off\", instead of the general API error line.\n\n**Why**\n\nA cut-off tool call now has its own message, which makes it easier to tell apart from other API errors.\n\n- Area: API Errors\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
