Worked on the Maestro repository to address a critical issue with nested sub flow printing when the --no-ansi option was used. The solution involved introducing unique keys for nested commands, enabling accurate tracking and output of complex command structures without affecting user-facing performance. This approach improved the reliability and maintainability of Maestro’s printing subsystem, particularly for advanced command flows. The work was implemented using Kotlin and focused on back end development, with comprehensive unit tests added to verify the new functionality. By resolving this bug, the developer enhanced output consistency and reduced user-visible inconsistencies in complex command scenarios.
