Worked on the aws/amazon-q-developer-cli repository to enhance the stability of transport-type configuration validation. Addressed a critical issue in the JSON schema by updating the schema reference from '#/$definitions' to '#/definitions', which resolved parsing and validation errors in the configuration flow. This fix, implemented using JSON and leveraging skills in configuration management and schema validation, directly reduced user-reported issues and improved the reliability of CLI transport operations. The work was tracked through a dedicated pull request, ensuring traceability and context for future maintenance. The focus remained on backend stability rather than feature development during this period.
