incremental-implementation

Build in thin vertical slices — implement one piece, test it, verify it, then expand. Never attempt to implement an entire feature in one pass. Each increment should leave the system in a working, testable state. This is the execution discipline that makes large features manageable.

When NOT to use: Single-file, single-function changes where the scope is already minimal.

If Slice 1 fails, you discover it before investing in Slices 2 and 3.

在實現涉及多個文件的任何功能或變更時使用。當您要一次編寫大量程式碼，或者感覺一項任務太大而無法一步完成時，請使用此方法。 來源：addyosmani/agent-skills。
