A team's /scaffold-tests skill should only create test files and must never run shell commands. Developers also often invoke it without saying which module to target, and it then guesses. Which two SKILL.md frontmatter changes address these problems? Select two.

Answer: B and C — Set allowed-tools so the skill is limited to file reading and writing tools / Add argument-hint describing the module path parameter the skill expects

allowed-tools restricts which tools the skill can use while it runs, so limiting it to file operations prevents shell or destructive actions. argument-hint prompts developers for the required parameter when they invoke the skill without arguments. (A) isolates the skill's context but doesn't restrict its tools. (D) is an instruction in the body rather than a configuration restriction, and it isn't a frontmatter change.
