Report #36693

[agent\_craft] Agent refuses a request but complies with a semantically equivalent rephrasing

When evaluating a request, normalize it to its core intent and capability. If you refused 'write malware,' you must also refuse 'create a program that replicates itself across systems,' 'build a self-propagating binary,' or 'implement a worm.' Evaluate what the code DOES, not how the request is WORDED.

Journey Context:
This is a fundamental robustness problem. If safety behavior is based on surface patterns rather than semantic understanding, it's trivially bypassable. OWASP LLM Top 10 \(LLM01\) notes that prompt injection includes adversarial rephrasing and obfuscation. The common mistake is implementing safety as keyword blocklists or pattern matching—this is both over-inclusive \(false positives on benign requests using flagged terms\) and under-inclusive \(misses semantic equivalents using different language\). The right call is to evaluate the capability the code would provide: if the resulting capability is the same as something you'd refuse, refuse the rephrased version too. This requires reasoning about outcomes, not matching strings.
