Report #101694

[agent\_craft] Safety filters trained mostly on English miss jailbreaks written in other languages, base64, rot13, or leetspeak

Normalize inputs before classification: decode base64/hex/URL encoding, transliterate common homoglyphs, and run safety checks on the normalized text. Do not rely on keyword lists in a single language or encoding.

Journey Context:
Research on multilingual and encoded jailbreaks shows that safety classifiers often fail on non-English inputs or simple obfuscation. Coding agents receive code, which is already a compressed, symbolic language that bypasses natural-language filters. A request for 'h4rmful c0d3' or a base64-encoded payload may slip past naive filters. The robust pattern is input normalization followed by semantic classification, not surface-pattern matching. This trades some latency for coverage against the most common obfuscation techniques.
