The premise
Feed the model snapshot files plus the components they cover; it groups them by signal and proposes a delete/keep/replace verdict.
What AI does well here
- Detect snapshots that mostly capture noise (dates, IDs)
- Spot duplicate snapshots across files
- Suggest behavior tests as replacements
What AI cannot do
- Know which UI states actually matter to your users
- Run the tests to confirm coverage
- Replace human design intent
