Challenge

Text Watermarking & Latency Impact Auditor with Claude Agents SDK and Credo AI

Implement a real-time text watermarking latency auditor using Claude Agents SDK and Credo AI to evaluate token generation overhead across quantized model variants. Measure throughput degradation accurately to ensure watermarking adds less than 3% overhead under peak serving loads.

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

Overhead Limit Test

Ensures overhead percentage added by watermarking is under 3%.

Binary check

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

Dimension 2

Watermark Detection Z-Score

Statistical confidence score of watermark detection. • target: 6 • range: 4-10

Binary check

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