Our review
Checks React feature flag states, compares release channels, and exports data as CSV.
Strengths
- Single command overview of all flags across channels
- Accurate channel-to-channel diff with --diff
- Flags grouped by cleanup status for prioritization
- CSV export for external analysis
Limitations
- Requires a local React repo set up with yarn
- Does not cover dynamic or server-side flags
- __VARIANT__ flags can be ambiguous without additional context
When you need to diagnose why a feature behaves differently across React release channels or plan flag cleanup.
If you are working on a non-React project or lack access to React's flag infrastructure.
Security analysis
SafeThe skill instructs running a local 'yarn flags' command to query feature flag states, with no destructive, exfiltrating, or network-dependent actions. It poses no meaningful execution risk.

Instructions
- Run

- For --diff, highlight meaningful differences
Common Mistakes
- Forgetting
__VARIANT__flags - These are tested both ways in www; check both variants - Comparing wrong channels - Use
--diffto see exact differences
