Challenge

Claude Agents SDK Urban Land Tender Bidding Assistant

Urban development authorities release prime land tender sites with complex zoning, plot ratio, and usage guidelines. Construct an autonomous land tender evaluation agent using Claude Agents SDK to calculate gross floor area, identify land use constraints, and estimate tender bids.

Delivery guide

How work is evaluated

Evaluation

Evaluates land tender metrics calculations and bid valuation accuracy.

Datasets

Shared data for this challenge

Review public datasets and any private uploads tied to your build.

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

gfa_math_validation

Ensures max_gfa_sqm equals site_area_sqm * gross_plot_ratio exactly.

Binary check

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

Dimension 2

bid_valuation_error

Percentage error between calculated residual land value and ground truth valuation. • target: 0.01 • range: 0-0.1

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 Claude Agents SDK with custom tool bindings for urban planning geometry

  • Parse site area, plot ratio, and allowable gross floor area (GFA) from URA releases

  • Enforce zoning overlay rules and transit-oriented development (TOD) requirements

  • Generate automated tender bid recommendation models based on land rate benchmarks
