  • Engineer — Learn: Research showing that annotating tool descriptions with privilege class reduces over-privileged selection significantly; a cheap design pattern worth adopting when building agentic pipelines — combine privilege labels with explicit least-privilege instructions in system prompts for best results.
  • SOC/IR — Skip
  • Leader — Learn: Establishes that LLM agents default to over-privileged tool use and that prompt-level controls can partially mitigate this; useful context when evaluating AI agent deployment risk or setting policy for agentic tooling in the enterprise.
