flags is an official React repository agent skill that inspects, compares, and debugs feature flag states across OSS and React Native release channels for developers tracing channel-specific behavior.
About
flags is an agent skill from facebook/react for checking feature flag states, comparing release channels, and debugging why features behave differently across builds. Options include showing all flags across channels, --diff between two channels, --cleanup grouped by cleanup status, and --csv CSV export. Documented channels span www and www-modern for Meta internal, canary, next, and experimental for OSS, plus rn, rn-fb, and rn-next for React Native. A legend marks enabled, disabled, __VARIANT__, and profiling-only flags. Developers reach for flags when a React or React Native feature works on one channel but not another and they need a structured flag inventory instead of manual source grep.
- Shows all flags across www, canary, next, experimental, rn and other channels
- Supports --diff to compare any two channels and highlight meaningful differences
- Includes --cleanup view to surface flags ready for removal
- Outputs CSV format for spreadsheet analysis when needed
- Explains output and common mistakes such as forgetting __VARIANT__ flags
