Make your prompt earn your trust. One convincing answer can hide a weak workflow. Try giving your prompt five chances to fail: a normal question, a boundary case, missing information, a disallowed case, and an instruction hidden in the input. Starter challenge: pick one repeatable task. Write one example where the answer is obvious—and one where the only honest answer is “I need more information.” Decide what a failure would look like BEFORE asking AI. Then stop tweaking by feel. The full AI Anonymous guide shows a five-case Promptfoo setup, two deliberate mistakes, and the checks that catch them. Start without an API key; connect your own model only when you are ready. Full walkthrough + downloadable exercise: https://jabsystems.io/ai-anonymous/promptfoo-earn-your-trust We tested the evaluation harness with hand-written answers, not an AI model. Five checks are a starting point, not proof of accuracy or security. AI Anonymous by JABSystems #AIAnonymous #PromptEngineering #OpenSource #AITools #JABSystems
