Fable is working excellent in my medium project with 250+ files and 60 odd thousand (and shrinking) lines of code. I am on MAX 5. However I don't permit the use of agents, use the /handoff method with compaction disabled. I never hit limits. Claude Code extension in VSCodium, with 5 MCP servers.

System prompt 19.9k System tools 11.8k Memory files 3.1k Skills 1.1k Compact buffer 3.0k

I should try using it too, just like you did. thanks!
