  "title": "The Implications of Linguistic Illegibility for LLM Security",
  "why_included": "Language-based monitoring cannot fully reveal an agent’s internal computation, the paper argues. Secure agent runtimes still need isolation and data-flow controls independent of self-reporting.",
  "summary": "The paper defines **linguistic illegibility** as a mismatch between model computation and the language emitted or recovered through probes. This weakens guarantees based on chain-of-thought monitoring, self-critique, or linguistic feature vectors.",
  "practical_implication": "Treat those signals as detection aids, not containment. Put tool-running agents behind **taint tracking**, robust virtualization, and policies that prevent model-produced data from influencing protected state.",
  "agent_context": "The paper defines **linguistic illegibility** as a mismatch between model computation and the language emitted or recovered through probes. This weakens guarantees based on chain-of-thought monitoring, self-critique, or linguistic feature vectors.\n\nTreat those signals as detection aids, not containment. Put tool-running agents behind **taint tracking**, robust virtualization, and policies that prevent model-produced data from influencing protected state.\n\nThis is a security argument rather than a reported empirical comparison. Taint tracking is presented as promising, while implementation costs and coverage are not quantified in the supplied material.",

  "connected_context": {
    "meaning": "This sharpens the case for external security boundaries: containment is needed not only because agents may exceed task intent, but because their visible reasoning and probe-derived features may not faithfully expose the computation driving an action. It therefore narrows chain-of-thought monitoring and self-critique to detection roles, while leaving the cost and completeness of taint-based enforcement unresolved.",
