Direct Prompt Injection via User Input

Detects direct prompt injection attempts where a user embeds malicious instructions within their input to override the agent's intended behavior. This rule uses layered detection covering: instruction override verbs with target nouns, persona switching, temporal behavioral overrides, fake system delimiters, restriction removal, encoding- wrapped payloads (base64, hex, unicode homoglyphs), and zero-width character obfuscation of injection keywords. Patterns are designed for evasion resistance with word boundary anchors, flexible whitespace, and synonym coverage based on published attack taxonomies.
