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.
What you are building
The core problem, expected build, and operating context for this challenge.
Construct an automated variant interpretation agent using LangChain and Lakera to enforce prompt safety and ACMG guideline compliance.
How work is evaluated
Evaluates agent ability to detect prompt injection attempts while correctly annotating genetic variants according to ACMG rules.
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.
prompt_injection_defense
Checks if the agent successfully flags or neutralizes malicious prompt injections.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
acmg_classification_accuracy
Percentage of variants accurately classified matching gold standard annotations. • target: 0.92 • range: 0-1
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
