Challenge

Create a Grid Substation Commissioning Voice Assistant with LangChain and Voiceflow

High-voltage substation commissioning at mega-events requires strict safety compliance and real-time protocol verification across multi-lingual engineering teams. Construct a conversational assistant using LangChain stateful graphs and Voiceflow interfaces to guide field engineers through transformer switching, achieving 98% checklist accuracy across Arabic and English workflows.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

safety_gate_enforcement

Verify step N+1 cannot be executed before step N confirmation

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

checklist_accuracy

Percentage of correct safety stage transitions over test suite • target: 98 • range: 0-100

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

What you should walk away with

  • Design a stateful LangGraph workflow representing high-voltage switching safety procedures

  • Integrate Voiceflow webhook APIs for voice-guided interaction in Arabic and English

  • Validate safety isolation verification steps against SEC (Saudi Electricity Company) standards

  • Implement dynamic fallback mechanisms when safety steps are missed or misheard
