Ralph Loop plugin: shell permission checker rejects --flags as 'multiple operations'

Bug

The ralph-loop plugin's /ralph-loop skill fails with a shell permission error when invoked with --completion-promise or --max-iterations flags. The permission checker interprets -- flags as separate shell operations rather than arguments to the script.

Reproduction

/ralph-loop:ralph-loop "Fix bugs" --completion-promise "PATCHED" --max-iterations 10

Error

Error: Shell command permission check failed for pattern "!
"/home/matt/.claude/plugins/cache/claude-plugins-official/ralph-loop/61c0597779bd/scripts/setup-ralph-loop.sh"
"Fix bugs"   --completion-promise "PATCHED" --max-iterations 10 ": This Bash command contains multiple operations. The following part requires
approval: --completion-promise "PATCHED" --max-iterations 10

What was tried

• Adding Bash(/path/to/setup-ralph-loop.sh:*) to permissions.allow in ~/.claude/settings.json — no effect, the error occurs before pattern matching
• Restarting the session after adding the permission
• Various quoting strategies for the prompt text

Expected behavior

The --completion-promise and --max-iterations flags should be recognized as arguments to the setup script, not as separate shell operations.

Environment

• Claude Code CLI
• Linux (Arch)
