Duncan's article published at https://www.iankduncan.com/engineering/2026-02-05-github-actions-killing-your-team states that GitHub Actions requires extensive workflow maintenance and produces fragile YAML configurations. The post identifies these factors as sources of ongoing engineering overhead.

This aligns with the 2023 Accelerate State of DevOps Report by Google Cloud which measured that complex CI/CD tooling correlates with longer lead times for changes and lower deployment frequency (https://cloud.google.com/blog/products/devops-sre/announcing-the-2023-accelerate-state-of-devops-report).

A 2022 ICSE paper titled 'Pain Points in Continuous Integration and Delivery' analyzed open source projects and reported that declarative pipeline definitions in tools such as GitHub Actions generate high debugging costs (https://dl.acm.org/doi/10.1145/3510003.3510204).
