Automating product deprecation

This post introduces Meta's Systematic Code and Asset Removal Framework (SCARF), a new internal tool designed to automate the complex process of product and feature deprecation. It details the challenges of safely removing code and data in a large organization, the failure modes that can arise without proper guidance, and how SCARF addresses these issues through workflow management, dependency analysis, and the creation of a deletion roadmap. The post highlights SCARF's ability to guide engineers, automate cleanup of unused assets, and work in conjunction with manual intervention to ensure efficient and safe deprecation.
