CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.90). The skill includes a "Companion check" that instructs the agent to run local shell commands (ls) and suggest installing packages (npx), which is unrelated to the game's design-pattern help and asks the agent to access/modify the user's system—a hidden/out-of-scope behavior.

MEDIUM W013: Attempt to modify system services in skill instructions.

• Attempt to modify system services in skill instructions detected (high risk: 0.70). The companion-check instructs the agent to run local shell commands to enumerate hidden skill directories and to offer/install missing companions using an npx skills add ... command, which encourages executing filesystem commands and installing remote code that can modify the host environment.
