Risk Level: SAFEPROMPT_INJECTIONCOMMAND_EXECUTION
Full Analysis
  • [PROMPT_INJECTION]: The skill provides a surface for indirect prompt injection by interpolating untrusted task descriptions and codebase context directly into agent instructions.
  • Ingestion points: The variables {{TASK_DESCRIPTION}} and {{ADDITIONAL_CONTEXT}} are used in references/loop-coordinator-prompt.md to define worker tasks.
  • Boundary markers: The prompt templates lack explicit delimiters or instructions to prevent agents from obeying commands embedded within the input data.
  • Capability inventory: Agents have access to the teams tool for delegation and the git tool for modifying the local codebase.
  • Sanitization: No validation or sanitization of the provided task description is performed.
  • [COMMAND_EXECUTION]: The skill instructs agents to execute arbitrary build and test commands from the local working directory.
  • Evidence: In references/loop-coordinator-prompt.md, sub-agents are directed to "run build, tests, linting -- actual commands" and "Run tests to verify they pass". This results in the execution of scripts defined in the repository, which could be malicious if the repository content is untrusted.
