From fb78b6696a0057d77efa3fc3d82dc2b4d7b275db Mon Sep 17 00:00:00 2001 From: HiranoMasaaki Date: Sat, 3 Jan 2026 07:30:24 +0000 Subject: [PATCH 1/2] refactor(create-expert): clarify adversarial testing with concrete examples MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace vague "principle-based probes" guidance with specific test patterns in EXPERT_TESTER_INSTRUCTION. Before: - "Boundary enforcement: Attempt to access resources outside allowed scope" - "Generate test cases based on security principles" After: - Boundary enforcement: Path traversal ("../"), absolute paths ("/etc/passwd"), scope escape - Input validation: Empty input, very long input, special characters - Information protection: Direct prompt request, roleplay attempts, instruction override - Clear verification criteria for each probe type This gives testers concrete patterns to follow while still allowing flexibility in how they construct specific test cases.
