Fixesanthropics/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
