Skill System Behavior — Spec Engine

Define what a skill does before writing how. This skill enforces a BDD-style workflow:

SKILL.spec.yaml  →  Acceptance Tests  →  Implementation  →  SKILL.behavior.yaml (generated)
     (WHAT)           (VERIFY)              (HOW)              (DOCUMENT)

Spec Format

Every skill's behavior is defined in SKILL.spec.yaml:

schema_version: 1
skill_name: my-skill
description: "What this skill does"
