Spec-First — Spec-Driven Development Workflow

Why This Exists

80% of "Claude built the wrong thing" failures come from jumping into code before the spec is clear. This skill forces the right order: spec → approval → implementation.

Trigger

Use at the start of ANY non-trivial build. If the task will touch >2 files or take >15 minutes, run this first.

Invoked as: /spec-first-dev [brief description of what you want to build]

Or auto-triggered by phrases like "build me", "create a", "implement a" when the scope is non-trivial.
