ralph-wiggum plugin: Multi-line bash in command markdown files causes 'Command contains newlines' error

Description

The official ralph-wiggum plugin's Skill commands fail with a security error when invoked via the Skill tool:

Bash command permission check failed for pattern "...": Command contains newlines that could separate multiple commands

Steps to Reproduce

1. Install the ralph-wiggum plugin from claude-plugins-official
2. Try to invoke the skill:

``
/ralph-loop Test prompt --max-iterations 1
``

1. Error occurs before command execution

Root Cause

The command markdown files (commands/ralph-loop.md and commands/cancel-ralph.md) use multi-line bash scripts inside `! blocks:

ralph-loop.md (lines 12-43):

\`\`\`!
"${CLAUDE_PLUGIN_ROOT}/scripts/setup-ralph-loop.sh" $ARGUMENTS

# Extract and display completion promise if set
if [ -f .claude/ralph-loop.local.md ]; then
  PROMISE=$(grep '^completion_promise:' ...)
  # ... 25+ more lines
fi
\`\`\`

cancel-ralph.md (lines 9-16):

\`\`\`!
if [[ -f .claude/ralph-loop.local.md ]]; then
  ITERATION=$(grep '^iteration:' .claude/ralph-loop.local.md | sed 's/iteration: *//')
  echo "FOUND_LOOP=true"
  echo "ITERATION=$ITERATION"
else
  echo "FOUND_LOOP=false"
fi
\`\`\`

Claude Code's Bash security check rejects commands containing newlines to prevent command injection. This check happens before the allowed-tools permission is evaluated.

Workaround

Calling the script directly works:

"/path/to/plugins/ralph-wiggum/.../scripts/setup-ralph-loop.sh" /tmp/project

Suggested Fix

1. Move multi-line logic into the shell scripts (e.g., add completion promise display to setup-ralph-loop.sh)
2. Keep command markdown files as single-line script invocations:

\`\`\`!
"${CLAUDE_PLUGIN_ROOT}/scripts/setup-ralph-loop.sh" $ARGUMENTS
\`\`\`

1. Create a cancel-ralph.sh script for the cancel command

Environment

• Claude Code version: Latest
• Platform: macOS
• Plugin source: claude-plugins-official marketplace

Files Affected

• commands/ralph-loop.md - has multi-line bash
• commands/cancel-ralph.md - has multi-line bash
• scripts/setup-ralph-loop.sh - needs completion promise display logic added
• scripts/cancel-ralph.sh - needs to be created
