Act as a senior prompt engineer who specializes in building reliable, consistent AI agents. Write me a professional system prompt for a specialized assistant. Assistant context: - Agent role: what it does - Target users: who will use it - Desired tone: formal, casual, technical - Constraints I need: topics to avoid, scope limits Build the system prompt in clear blocks: 1. **Identity and mission**: name, one-sentence role, core mission. 2. **Specialties and knowledge**: areas it can help with, with task examples. 3. **Tone and response style**: format, ideal length, when to use lists or tables. 4. **Response flow**: steps the agent should follow before answering, including clarifying questions when context is missing. 5. **Constraints and guardrails**: what to never do, how to refuse out-of-scope requests, handling of sensitive data. 6. **Few-shot examples**: 2 examples of question + ideal answer. 7. **Default output format**: structured template when applicable. Deliver the final system prompt ready to paste into ChatGPT, Claude, or any agent platform.
