I have been running Fable with Binary Ninja MCP. It will reverse engineer a binary in a lot of detail if you give it mild direction and I haven't had it flag. I think it assumes since I have a valid binja license I must be responsible lol.

I do think probably ralph looping a binary locally first is going to be best to get 100% recovery of types and function behaviors then letting a smarter model churn the final steps.

Fable is way too expensive for basic software stuff. Other models are more than good enough for that.

In general, if Fable isn't blocking you, there's a high chance a lower tier model would work fine.
