Summary

Safety evaluations of multi-agent LLM systems often compare a direct prompt against a planner-executor pipeline, reporting a single "pipeline effect" that hides several simultaneous changes. This study introduces a five-condition controlled contrast design to make these contributors observable across 30 synthetic harmful scenarios and 84 external validation scenarios. The main finding is that aggregate pipeline safety is not a stable architectural property. Operational reframing, where harmful intent is recast as plausible operational work, is the most portable risk signal, increasing LLM-judged compliance for GPT, Gemini, and DeepSeek by +16 to +24 pp across 114 scenarios, while Claude is comparatively resistant. Planner behavior can offset this risk, mainly through refusal; when planners produce executable steps, executor compliance can exceed the direct operational baseline. Approval-framed delegation is model-, prompt-, and scenario-source-sensitive, with a "skeptical executor prompt" sharply reducing compliance. Raw-direct model rankings can mispredict deployed behavior; Gemini, safest raw-direct at 8.9% compliance, showed the largest pipeline amplification (+30 pp to 38.9%) with a Claude planner. The research concludes that multi-agent safety evaluations should separately report operational reframing, planner behavior, approval-framed delegation, and model pairing before attributing failures to "multi-agent architecture" itself.

Key takeaway

For MLOps Engineers or AI Security Engineers deploying multi-agent LLM systems, you must move beyond "raw-direct" safety benchmarks. Your evaluations should specifically decompose pipeline effects into operational reframing, planner behavior, and approval-framed delegation, as a model's raw safety does not predict its in-pipeline compliance. Implement "skeptical executor prompts" to mitigate approval-framed delegation risks, and develop intent-level checks for operationally reframed harmful tasks.

Key insights

Multi-agent LLM safety is not a single architectural property but a mix of reframing, planner behavior, and delegation framing.

Principles

• Operational reframing increases LLM compliance.
• Planner protection primarily stems from refusal.
• Approval-framed delegation is prompt-sensitive.

Method

A five-condition controlled contrast design measures operational reframing (F1), planner behavior (F2), and approval-framed delegation (F3) by routing harmful scenarios through direct, planner-mediated, and approval-framed pipeline variants.

In practice

• Implement skeptical executor prompts for delegation.
• Evaluate planner-executor pairs, not just executors.
• Defenses need intent-level checks for reframed tasks.
