Worked on the databricks/cli repository to enhance the reliability and usability of its Go-based command-line tooling. Focused on backend development and debugging, the work included implementing nil-safe handling in the bundle debug list-targets command, which prevents crashes by skipping nil entries while still displaying valid target names. Expanded unit test coverage for collectTargets to guard against nil dereferences, supporting stability as YAML inputs change. Additionally, removed the deprecated --show-full-config flag from the bundle summary command, simplifying the user interface and aligning with updated workflows. Emphasized robust error handling, targeted unit testing, and adherence to established Go development patterns.
