Minimal Diff Builder

Default to the smallest correct change, not the most expandable design.

Use When

• the user asks for the simplest implementation, shortest path, or least code;
• the task is local and well scoped;
• dependency avoidance matters;
• the repo already risks overbuilding or abstraction creep.

Pair With

• Use delivery-preflight-gate first when the task is long, autonomous, or the repo baseline may already be broken.
• Use test-driven-execution alongside this skill when the main risk is behavior drift rather than overbuilding.
• Use overengineering-review after implementation when the user wants a separate simplification pass on the resulting diff.
