Kakarot CI - Stop writing tests. Start shipping code.

Kakarot CI generates unit tests that actually run. No more copy pasting into ChatGPT or fixing broken imports. It uses AST analysis to detect changed functions and create accurate Jest or Vitest tests. Tests are executed, failures are automatically corrected, and results follow your TypeScript and linting rules. Runs in GitHub Actions or locally. Works with any LLM provider. Your API key, your CI runner, your data.
