Build MSME Credit Underwriter with Claude Agents SDK and o3 Reasoning

MSME credit decisioning requires accurate risk assessment across non-standardized bank statements and tax filings. Build an autonomous underwriting agent using Claude Agents SDK and o3 deep reasoning models to calculate risk scores and credit limits with complete regulatory transparency.

What you are building

Build an MSME credit assessment engine combining Claude Agents SDK tools and o3 model reasoning for Account Aggregator financial records.

How work is evaluated

Evaluation

Evaluates underwriting decision accuracy and transparency against benchmark MSME loan histories.

Datasets

Public datasets, plus the private datasets you have access to.

How submissions are scored

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

audit_trail_exists

Checks that complete audit trail reasoning was generated

Binary check

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

Dimension 2

underwriting_accuracy

Accuracy relative to gold standard credit outcomes • target: 0.92 • range: 0-1

Binary check

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

Learning goals

  • Construct multi-turn financial document reasoning workflows with Claude Agents SDK

  • Leverage OpenAI o3 model reasoning capabilities for complex cash flow analysis

  • Generate explainable credit score outputs aligned with RBI lending standards
