Role-Readiness Proof / Capstone
Build a production prompt system for a real workflow: define system/developer/user contracts; create structured outputs and few-shot examples; add RAG grounding with citations and one tool/MCP integration; version the prompt library; build a human + automated eval set; compare prompt variants; track task success, groundedness, hallucination, latency and token cost; red-team injection/jailbreaks and document rollback/escalation.
Proof Rubric
- Prove reproducible prompt quality rather than clever wording: clear instruction hierarchy
- reliable structured outputs
- grounded responses
- measurable task success
- versioned test cases
- error analysis
- security boundaries
- safe tool behavior
- latency/cost awareness
- documentation of model limitations and tradeoffs
