Feature Spec Writing

Purpose

Creates implementation-ready feature specifications that break down PRD requirements into detailed, actionable specs with comprehensive edge case coverage.

When NOT to Use This Skill

• Initial product requirements (use prd-writing instead)
• System architecture design (use technical-spec-writing instead)
• Reviewing existing specs (use feature-spec-reviewing instead)
• Bug fixes (no spec needed, just fix it)
• Minor enhancements < 1 day of work (overkill)
