- The catalog covers policy-version retrieval, customer-data isolation, and prompt injection, with listed exercises ranging from 14 to 30 test cases.
Field notes
The visible catalog groups three insurance-themed exercises under core and advanced levels, with estimated completion times of 20–40 minutes and 14–30 test cases. Scenarios cover policy-version retrieval, customer-data/cache isolation, and evidence injection that could authorize an unsafe tool call. The site explicitly says its insurer, policyholders, documents, and incidents are fictional; it also warns that early-release grading may change.
