Real-Time EV Subsidy Compliance Streaming Agent with Vercel AI SDK

Automating incentive eligibility under national clean energy initiatives requires high-throughput stream processing of telematics and compliance documentation. Build a streaming analytics agent using the Vercel AI SDK in Next.js to stream real-time battery usage validation and claim compliance results for EV manufacturers.

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

pli_threshold_check

Ensures claims with <50% domestic addition are rejected.

Binary check

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

Dimension 2

streaming_first_token_latency_ms

Latency in milliseconds before first response token. • target: 400 • range: 0-1500

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

  • Leverage Vercel AI SDK `streamText` and `generateObject` for real-time streaming interfaces.

  • Integrate tool calling with streaming JSON payloads in TypeScript/Next.js.

  • Implement PLI (Production Linked Incentive) scheme rule validators for clean energy logistics.
