Why Plan Cascade?

Traditional AI coding assistants hit a wall with large, complex projects:

Challenge	Conventional AI	Plan Cascade
Complexity	Gets lost in large codebases	Decomposes into manageable units
Parallelism	Sequential, one-at-a-time	Independent tasks run in parallel
Context	Lost during long sessions	Design docs + durable context survive compaction
Quality	Manual verification needed	Automated testing & linting at each step
Control	Black box execution	Transparent, inspectable workflow

The Solution: Cascading Decomposition
