[Mahmoudgalalz]

• feat: Database introspection, AI context & BYOC settings

Architecture diagram (high level)

Implementation

1. Personal AI provider credentials and model selection
2. Suggest faster ways to write queries and show how much quicker they’ll run
3. Ask questions in normal English and get instant answers
4. Spot errors in failed queries and suggest quick fixes
5. Run queries in sandbox [ Very Important move ]

• Add sandbox query execution (POST /query/sandbox, transaction + rollback)
• Add suggest-fix for failed queries (structured errors, POST /chat/suggest-fix, UI)
• Support OpenAI/Anthropic/Gemini in settings and chat (provider, model, optional API keys)
• Auto-run chat SQL in sandbox and show result inline
• Add query analyze (EXPLAIN) and suggest-optimization with timing comparison in runner
• Fix proxy adapter calls (createOpenaiChat/createAnthropicChat model, apiKey order)
• Fix query route chaining, ApiErrorType 400|500, ExecuteQueryResult types

@husamql3, your AI roadmap is done, smart boy

I suggest more enhancements on it using RAG and more context awareness, but this does the job for now, and it could be easily enhanced in the future.

Thanks a lot for the contribution, I can see a huge progress here ❤️

It's kinda a big one so it's taking a bit to merge, I'm on it
