Fixed
This release fixes a long-standing Snowflake schema issue and makes Claude AI dramatically more useful when queries fail. Date: May 24, 2026
🎉 New
Claude AI sees your errors automatically. The chat panel now reads the last 5 query errors with timestamps and SQL snippets. Ask Claude "what happened?" after a failed query and it analyzes the actual error in context of your schema. A new red error context chip appears alongside the SQL/Python/Schema chips when recent errors are present.
Snowflake error messages now show what Snowflake actually said. Instead of cryptic "HTTP 422" responses, QueryFlow parses the full Snowflake JSON error response. Codes, SQL state, and statement handles are all surfaced. Errors are selectable, copyable with one click, and have retry buttons.
14-day trial paywall redesigned. Prominent "14 DAYS FREE" hero card on the paywall with green trial badges on price cards. Dynamic "Try Free for 14 Days" button label.
🚀 Improved
Error copy infrastructure. New universal copy buttons across error states. Bug reports can now include full structured error reports with one click — message, JSON, SQL, statement handle.
System prompt for Claude. Now includes "Recent execution errors (most recent first)" block when applicable.
🐛 Fixed
Snowflake INFORMATION_SCHEMA queries under PAT auth. The 391918 "must specify database" error for user-created Snowflake databases. Schema explorer queries are now fully qualified (e.g.,
FROM <DATABASE>.INFORMATION_SCHEMA.COLUMNS).DBExplorer error handling. New
missingDatabaseerror case with a clear message when no database is configured on a connection.
Available now on the Mac App Store.
