Risk Level: MEDIUMCOMMAND_EXECUTIONPROMPT_INJECTION
Full Analysis
  • [COMMAND_EXECUTION]: The skill obtains a {target_root} path via the AskUserQuestion tool and then directly interpolates it into a shell command: python3 .plan/execute-script.py ... --value {target_root}. A user or an automated process providing a path containing shell metacharacters (e.g., ;, &, or backticks) could achieve arbitrary command execution.
  • [PROMPT_INJECTION]: The skill is designed to recursively read and analyze a corpus of markdown files, which constitutes a surface for indirect prompt injection.
  • Ingestion points: All SKILL.md and markdown files within the user-specified {target_root} directory are read into the agent's context.
  • Boundary markers: The instructions lack delimiters or explicit warnings to the agent to disregard instructions potentially embedded within the audited markdown files.
  • Capability inventory: The skill possesses the Bash tool and executes project-specific management scripts, providing a pathway for malicious instructions to influence the system.
  • Sanitization: There is no evidence of sanitization or validation of the content retrieved from the target skill corpus before it is processed by the agent.
