A developer built a prompt injection detector for LLMs using a deterministic, signature-based approach rather than machine learning. This method aims to provide reliable and auditable security by avoiding the uncertainties of probabilistic models. The detector identifies 22 distinct injection patterns across seven languages, including fake system overrides, instruction ignores, role redefinitions, and encoded payloads. AI
