SUPABASE HARDENS AI STORAGE GUIDANCE, CLI SHEDS LAST GO BINARIES

By RepoJournal · Filed · About Supabase

The Assistant now blocks dangerous RLS patterns on public buckets while the CLI completes its TypeScript migration, eliminating the final Go proxy layer.

Supabase shipped a critical update to its AI Assistant that teaches it to recognize and block overly permissive RLS policies on storage buckets [1]. Public buckets with broad read access can accidentally expose sensitive data like profile pictures or private files; the new evals catch this before deployment and guide users toward restrictive patterns. This closes a gap where developers could unknowingly grant world-readable access to bucket contents. Meanwhile, the analytics SQL safety series crossed the finish line [2], with every analytics query now flowing through branded SafeLogSqlFragment inputs. On the CLI front, three major command families completed their TypeScript port: network-bans [3], vanity-subdomains [5], and snippets [6], eliminating the last Go proxy handlers that powered Phase 0 operations. Version 2.102.0 [4] also restored shell completion in legacy environments and silenced CI identity spam. The CLI is now native TypeScript end-to-end.
