Worked on packaging tooling across the forcedotcom/packaging and salesforcecli/plugin-packaging repositories, focusing on dependency graph capabilities and visualization enhancements. Developed a core engine for generating and processing package dependency graphs, introducing a new CLI command for displaying dependencies and improving visualization with node highlighting and version emphasis. Leveraged TypeScript and Node.js to implement GraphViz-based DOT output for visualizing package dependencies, adding configurable options and comprehensive unit and integration tests. Updated package version management to reflect release readiness and addressed visualization accuracy for specific API versions. These contributions enabled faster dependency analysis and more reliable packaging decisions for Salesforce CLI users.
