deprecation-and-migration is a Claude Code skill that encodes the workflows and best practices senior engineers use when managing deprecation and migrations across software projects. It guides structured decisions about whether to maintain or retire existing code, replace legacy APIs and systems, consolidate duplicates, and remove dead code. A key focus is deprecation planning at design time — embedding lifecycle decisions into new systems from the start rather than as an afterthought. The skill is part of Addy Osmani's agent-skills collection, installable via the Claude Code Marketplace or npx, and activates automatically in the relevant engineering context. It targets senior developers and team leads who need a consistent, systematic approach to feature sunsets, user migration between implementations, and long-term technical debt management.
