Worked on the chromaui/chromatic-cli repository to stabilize Storybook CSF detection in response to changes introduced by storybook-rsbuild. Addressed a critical bug by updating the module mapping logic, expanding the list of resolved modules, and explicitly adding './storybook-config-entry.js' as an entry point. This technical approach improved the reliability of automated story rendering and reduced pipeline failures for Chromatic CLI integrations. The work involved TypeScript and focused on build tools and configuration management, ensuring that CSF files are detected correctly and that the integration remains robust as Storybook evolves. All changes were thoroughly documented for traceability and reproducibility.
