Spec Writing (Spec Writer)

Overview

This is a specialized skill for product specification and strategy. It supports product managers (PRD, feature specifications, prioritization, roadmaps) and AI strategy (AI/ML adoption strategy, digital transformation roadmap).

Grant program and R&D project applications are outside the scope of this skill. For general government grant programs (startup, small business, SME business plans, applications), moai-business:kr-gov-grant, and for academic/R&D and research funding projects (NRF, IITP, KIAT), moai-research:grant-writerroute to.

Trigger Keywords

PRD, feature specification, spec, product planning, AI strategy, digital transformation, product manager

Workflow

Load and execute strategy guide

Receive user request → determine the relevant strategy guide → references/{id}.md(product-manager / ai-strategy) load → execute according to the strategy guide → request user review after generating the output

For complex strategic judgments, if the sequential-thinking MCP is installed, mcp__sequential-thinking__sequentialthinkingand if not, ultrathink substitute with keyword-based deep reasoning.

If a grant program or R&D project request comes in

For general government grant programs (startup, small business, SME business plans, applications), moai-business:kr-gov-grant, and for academic/R&D and research funding projects (NRF, IITP, KIAT forms), moai-research:grant-writeris responsible. This skill routes such requests to the two skills and does not possess application writing guidelines.

Usage Examples

  • "Write a PRD for a new SaaS service"
  • "Write an AI-based recommendation system adoption strategy report"
  • "Organize product feature priorities"
  • "Establish a digital transformation roadmap"

Output Format

  • PRD (Product Requirements Document)
  • Feature Specification
  • AI/ML Adoption Strategy Report
  • Roadmap and Milestones

Precautions

Situation Solution
Conflicting stakeholder requirements We help with MoSCoW classification based on prioritization criteria (business impact vs development complexity)
Unclear prioritization criteria We design feature priorities together using the RICE scoring framework
Difficulty defining technical specifications We present points for discussion with the development team as a non-functional requirements checklist
Grant program or R&D project application request moai-business:kr-gov-grant(general government grant programs) or moai-research:grant-writer(R&D/research funding)

2026 PRD Writing Trends

AI-based PRD writing (2026 standard)

  • Using ChatPRD: Automatically generates engineer-friendly specification documents from meeting notes and user feedback
  • AI draft generation: After writing a PRD draft with LLMs such as Claude and GPT, the PM reviews and supplements it
  • Prompt design: Include "product name, user problem, solution, success metrics" in the prompt

Essential PRD components (Korean PM standard)

Item Description
Background & purpose Why this feature is needed (business impact)
User story "As a user, I want ~ because ~"
Functional requirements Specific feature list, priorities (Must/Should/Could)
Non-functional requirements Performance, security, accessibility criteria
UX wireframe Layout draft or reference URL
Success metrics (KPI) Metrics to measure after launch (DAU, conversion rate, NPS, etc.)
Out of scope What is not included in this release
Schedule MVP launch date, milestones

Korean PM ecosystem

  • Naekarakubae: Refer to the PM competency standards of Naver, Kakao, Line, Coupang, and Baemin
  • Agile/Scrum: Writing PRDs by sprint is the standard. Define feature scope based on 2-week sprints
  • PM communities: Product Manager Korea, PM study groups, LinkedIn networks

Post-processing chain

After completing narrative documents such as PRDs and AI strategy reports, finish with the following chain (excluding tables and numerical data; applies only to the narrative body text):

moai-product:spec-writer → moai-core:ai-slop-reviewer → moai-content:humanize-korean

  • moai-core:ai-slop-reviewer: Check and refine AI-specific clichés, exaggeration, and redundancy.
  • moai-content:humanize-korean: Final polish into natural Korean sentences.
