The document lists the top 10 pipeline mistakes, including unsafe secrets, untraceable artifacts, environment-specific deploy packages, lack of testing, use of bleeding edge technology, overly complex builds, flaky builds, overuse of versioning, implicit assumptions, and reliance on dubious plugins. The author provides recommendations to address each mistake, such as using secret stores, adding versioning and links to artifacts, deploying the same packages to all environments, including quality checks, ensuring deployable technology and available agents, splitting processes, enabling reproducible builds, adding version specifications, checking tool requirements, and using autonomous pipelines.
