Fixes anthropics/claude-code#12170 The ralph-wiggum slash commands had multi-line bash scripts in their \`\`\`! blocks. Claude Code's security check blocks commands with newlines to prevent command injection, causing the error: "Command contains newlines that could separate multiple commands" Changes: ralph-loop.md: - Remove multi-line bash from code block - Keep single-line call to setup script - Keep scoped allowed-tools for security cancel-ralph.md: - Replace multi-line bash with step-by-step instructions - Add Read tool to allowed-tools (needed to read iteration count) setup-ralph-loop.sh: - Add completion promise display logic (moved from ralph-loop.md) - Uses COMPLETION_PROMISE variable directly instead of reading from file
