Casualty Litigation Risk & Nuclear Verdict Forecasting with Google ADK and OpenHands
Nuclear verdicts exceeding $10M increased by 40.7% in recent commercial liability litigations. You will build an automated litigation trajectory forecaster using Google ADK (Agent Development Kit) integrated with Gemini 1.5 Pro and OpenHands code agent execution. The agent must predict nuclear verdict probability with AUC-ROC > 0.85 and forecast damages within 15% error.
What you are building
The core problem, expected build, and operating context for this challenge.
Develop an automated legal risk trajectory predictor using Google ADK and OpenHands agent execution to project potential nuclear verdict exposures.
How work is evaluated
Evaluate nuclear verdict probability forecasting accuracy on 200 historical commercial auto liability cases.
Shared data for this challenge
Review public datasets and any private uploads tied to your build.
How submissions are scored
These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.
valid_prob_range
Probability must be strictly between 0.0 and 1.0.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
auc_roc
Area under ROC curve for nuclear verdict classification. • target: 0.85 • range: 0.5-1
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
What you should walk away with
Build a Google ADK agent using Gemini 1.5 Pro to parse legal dockets and claim files.
Integrate OpenHands runtime environment to execute complex statistical regression scripts.
Analyze key nuclear verdict predictors like jurisdiction severity, plaintiff counsel history, and injury type.
Output structured litigation reserve adjustment recommendations for claims officers.
Reference links and supporting material
