[gotcha] Assuming a system prompt is secure just because it survives 'Ignore previous instructions'

Test defenses against advanced, contextual attacks \(like role-playing, code-switching, or multi-turn crescendos\) rather than just explicit instruction overrides. Use automated red-teaming tools to evaluate robustness comprehensively.

Journey Context:
Many developers test their prompt defenses by typing 'Ignore previous instructions' and seeing if the model refuses. This gives a false sense of security. Modern attacks use subtle psychological manipulation, fictional scenarios, or multi-step logic that never explicitly mentions ignoring instructions, but achieves the same result. Comprehensive red-teaming is required.
