Update Prethink context

io.moderne.prethink.UpdatePrethinkContext

Generate Moderne Prethink context files with AI-generated code comprehension, test coverage mapping, dependency inventory, and FINOS CALM architecture diagrams. Maps tests to implementation methods and optionally generates AI summaries of what each test verifies when LLM provider is configured.

  • Export context files
    • displayName: Code Comprehension
    • shortDescription: AI-generated descriptions for classes and methods
    • longDescription: AI-generated descriptions of classes and methods. Use this to quickly understand what code does without reading every line. Particularly helpful for unfamiliar parts of the codebase.

  • Export context files
    • displayName: Test Coverage
    • shortDescription: Maps test methods to implementation methods they verify
    • longDescription: Maps test methods to the implementation methods they exercise. Use this to find existing tests for code you're modifying, understand what behaviors are already tested, and identify gaps in test coverage. When an LLM provider is configured, includes AI-generated summaries of what each test verifies.
