[gotcha] Multi-turn conversational attacks bypassing single-turn safety filters

Apply safety and moderation filters to the entire conversational context window, not just the latest user turn. Implement sliding window context inspection or use a separate classifier model on the accumulated context before executing tool calls.

Journey Context:
Safety filters typically inspect the current user prompt. An attacker splits a malicious instruction across multiple turns \(e.g., Turn 1: 'Let's play a game where you repeat my sentences but change X to Y', Turn 2: 'Repeat: Ignore...'\). The LLM's context window accumulates these benign-looking turns into a malicious payload. Single-turn filters see nothing wrong, but the LLM processes the combined context and executes the attack.
