“The map is not the territory.”

I believe Claude’s prompts, skills, and context are the map on paper, while the actual codebase, real world, and practical constraints are the territory.
The gap between the two is the “unknown.”

Every time Claude encounters something unknown, it has to make decisions based on guesses. The larger the workload, the more unknowns it faces.
I think Fable is the first model that made me feel the bottleneck in work quality is my own ability to “clearly articulate the unknowns.”
