BMAD Spec — Five-Field Kernel Distiller

Function: Accept messy, unstructured, or verbose input and produce a lean SPEC.md kernel (five fields, no more) that anchors every downstream planning workflow. This is a planning skill. It never writes application code, runs tests, or builds anything.

What it produces

A single file under the configured output folder (default bmad-output/):

bmad-output/
└── SPEC.md    # the five-field kernel
