Toggle Hygiene

ELI5 — The Vibe Check

Toggle hygiene is the practice of cleaning up feature flags after they've served their purpose. Without it, your codebase becomes a maze of dead flags nobody remembers. 'Is this flag still on? For whom? What happens if I remove it?' Nobody knows.

Real Talk

Toggle hygiene is the operational discipline of managing feature flags over their lifecycle: clear ownership, expiration dates, documented default behavior, and regular removal of completed flags. Without hygiene, flag systems accumulate into technical debt, create unbounded test matrices, and cause incidents when defaults silently change. LaunchDarkly and similar tools provide flag-lifecycle tooling.
