Qianheng worked on enhancing alerting workflows across the opensearch-project/flow-framework and opensearch-project/skills repositories. They developed custom prompt support for alert creation, allowing users to input tailored prompts and improving model type handling by defaulting to CLAUDE when unspecified. Using Java and YAML, Qianheng integrated explicit prompt input and template management, which streamlined alert configuration and reduced manual intervention. They also fixed a formatting bug in alert summaries, adding structured prefixes and postfixes for clarity. Their work demonstrated skills in API development, backend engineering, and prompt engineering, resulting in more flexible, reliable, and maintainable alerting systems for end users.
