I am struggling to build a solid system instruction set for a financial advisory virtual assistant. The model frequently hallucinates policy details. Does anyone have an advanced template or structured workflow to optimize prompt engineering for chatbot development that blocks unsafe financial advice?

Forcing the model to cite specific system data sources fixes this issue completely.
In highly regulated sectors like finance, your prompt architecture must use isolated operational blocks. Do not combine instructions with raw data. Create a clear hierarchy: first, define a strict "Auditor Persona"; second, establish an immutable "Safety Rubric" detailing what cannot be said; third, inject a localized knowledge base payload. You must explicitly instruct the chatbot to state "I cannot answer" if a user query falls outside the provided reference text. This explicit negative constraint tuning is the absolute key to preventing hallucinations.
How are you validating user queries before they hit the LLM context? Are you passing unvetted user text straight into your core generation pipeline?
We actually set up a secondary, tiny classification prompt layer right at the gateway, Gregory. It scans the raw user input for injection attacks or out-of-bounds financial topics before the primary chatbot even sees it. This step keeps our main prompt clean and heavily reduces processing overhead.
That is a fantastic point, Douglas. Forcing a strict source citation workflow inside the prompt template ensures that the generation layers remain strictly anchored to verified data points, which naturally purges rogue logical assumptions from the final output text.
