Challenge

Claude Agents SDK & Langfuse MHS Device Control Auditor

Operating physical devices via autonomous AI agents creates safety risks if hardware commands lack verification and observability. Build a Claude Agents SDK system integrated with Langfuse telemetry to safely issue Model Hardware Standard (MHS) device commands, intercept policy violations, and maintain full step-level audit trails.

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

zero_unsafe_execution

Ensures no commands exceeding hardware safety limits were executed.

Binary check

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

Dimension 2

audit_trace_coverage

Percentage of agent tool calls captured in Langfuse traces • target: 1 • range: 0.99-1

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

  • Implement safe physical device control tools conforming to the MHS specification

  • Use Claude Agents SDK extended thinking and tool-use capabilities for command planning

  • Integrate Langfuse for full trace observability, payload capture, and latency tracking

  • Enforce hardware safety boundary checks prior to transmitting actuator signals
