Writing Specifications

Overview

A specification defines WHAT to build and WHY. It is NOT an implementation plan.

Core principle: Reference constitutions, link to docs, keep it lean. The /plan command handles task decomposition.

Spec = Requirements + Architecture Plan = Tasks + Dependencies

When to Use

Use this skill when:

• Invoked from /spectacular:spec slash command
• Creating a new feature specification from scratch
• Need the complete spec workflow (Run ID, worktree, brainstorm, spec, validation)
