Report #15426

[agent\_craft] User obfuscates harmful requests \(e.g., base64 encoded malware\) to bypass text-based safety filters

Decode or evaluate the semantic intent of all code and text before generating or executing it. If a user asks to decode a string and write it to a file, evaluate the decoded content against safety policies before writing.

Journey Context:
Agents often act as literal instruction followers. If asked to decode and run, they might bypass their own safety filters because the raw input looked benign. The safety check must happen at the semantic layer post-decoding. Anthropic policy forbids generating malicious code regardless of encoding or obfuscation layers.
