Challenge

Build a LangChain & Lakera Guardrailed Genomic Variant Annotation Agent

Clinical genomic pipelines risk reporting non-validated variant predictions and prompt injections from untrusted external text. Build a LangChain agent integrated with Lakera guardrails to parse ACMG evidence criteria, filter unsafe prompt inputs, and output validated JSON variant classification summaries.

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

prompt_injection_defense

Checks if the agent successfully flags or neutralizes malicious prompt injections.

Binary check

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

Dimension 2

acmg_classification_accuracy

Percentage of variants accurately classified matching gold standard annotations. • 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

What you should walk away with

  • Implement a LangChain agent framework capable of parsing missense variant effect predictions

  • Integrate Lakera AI guardrails to neutralize adversarial prompt injections in patient clinical notes

  • Structure variant outputs against American College of Medical Genetics (ACMG) standard criteria

  • Evaluate performance using exact precision-recall metrics on genomic benchmark datasets
