Spec Writer Skill

Purpose

Produce a structured SPEC.md before any design or implementation begins. This is Phase 0 of the feature lifecycle pipeline (spec --> design --> plan --> implement --> validate --> release). The spec defines WHAT to build and WHERE the boundaries are. It says nothing about HOW.

Instructions

Step 1: Gather Context

1. Read the repository CLAUDE.md if present
2. Ask the user what feature or capability they want to specify
3. Identify the target users/roles (who benefits?)
4. Identify existing related functionality (what already exists?)

GATE: You have a clear understanding of the feature intent and target users before writing any stories.

Step 2: Write SPEC.md
