Exam Generation Engine
Auto-generate exams with difficulty calibration, rubric generation, and anti-cheating variation.
Automated exam generation system that creates assessments from curriculum materials with precise difficulty calibration. Azure OpenAI generates questions across Bloom's taxonomy levels, produces detailed rubrics and answer keys, and creates anti-cheating question variations. Blob Storage manages curriculum documents and exam banks, Cosmos DB stores question metadata and difficulty analytics, and Functions orchestrate the generation pipeline with batch processing support.
Architecture Pattern
Curriculum → question generation → difficulty calibration → rubric + answer key → anti-cheat variations
Azure Services
DevKit (.github Agentic OS)
- agent.md — root orchestrator with builder→reviewer→tuner handoffs
- 3 agents — Exam Builder (gpt-4o), Reviewer (gpt-4o-mini), Tuner (gpt-4o-mini)
- 3 skills — deploy (203 lines), evaluate (129 lines), tune (245 lines)
- 4 prompts — /deploy, /test, /review, /evaluate with agent routing
- .vscode/mcp.json — FrootAI MCP with OpenAI key input + envFile
TuneKit (AI Config)
- config/openai.json — question generation and rubric prompts
- config/exam.json — difficulty distribution, question types, Bloom's levels
- config/guardrails.json — fairness, bias detection, content appropriateness
- evaluation/eval.py — Difficulty accuracy >85%, Rubric coverage >90%
Tuning Parameters
Machine evidence
FrootAI evidence lifecycle
This is an internal evidence maturity label, not third-party certification, accreditation, legal compliance, or a production guarantee. Missing or expired evidence demotes automatically; catalog claims cannot promote a play.
This play currently has design evidence only. A runnable scenario, endpoint evaluation, and build receipts are the next contiguous gates.
Repo Intelligence
v1A no-clone, revision-pinned map for agents and humans. Observed evidence is separated from inferred flow so the output stays useful without pretending to be a full call graph.
