Worked on the nektos/act repository to address a critical issue in reusable workflow input propagation, focusing on improving reliability in workflow automation. Implemented a targeted fix in Go and YAML that ensures workflow_dispatch inputs are only applied when workflows are triggered directly, preventing unintended input overrides during workflow_call invocations. This adjustment guards against mis-delivery of parameters across chained workflows, maintaining consistent and predictable behavior for both standalone and reusable workflows. The solution was carefully scoped to minimize changes to existing logic, demonstrating a precise approach to workflow orchestration and bug resolution using GitHub Actions and Go development best practices.
