Structured Requirements Documents

Build Status Lint Status Go Report Card Docs Visualization License

A structured format for requirements documents with Go data types, JSON serialization, and markdown generation. Supports three document types that form a natural workflow:

MRD (Market Requirements) → PRD (Product Requirements) → TRD (Technical Requirements)

Overview

This library provides comprehensive, machine-readable formats for requirements documents:

  • MRD - Market Requirements Document: Market analysis, competitive landscape, buyer personas, positioning
  • PRD - Product Requirements Document: Personas, user stories, functional/non-functional requirements, roadmap
  • TRD - Technical Requirements Document: Architecture, technology stack, APIs, security design, deployment

Each document type supports:

  • Mandatory and optional sections for flexibility
  • JSON serialization with Go types
  • Markdown generation with Pandoc-compatible YAML frontmatter
  • Validation of required fields

Installation

go install github.com/grokify/structured-requirements/cmd/srequirements@latest

Or build from source:

git clone https://github.com/grokify/structured-requirements.git
cd structured-prd
go build -o srequirements ./cmd/srequirements

CLI Usage

The srequirements CLI provides commands for each document type:

# PRD commands
srequirements prd generate <file.json>      # Generate markdown from PRD
srequirements prd validate <file.json>      # Validate PRD structure
srequirements prd check <file.json>         # Check PRD completeness

# MRD commands
srequirements mrd generate <file.json>      # Generate markdown from MRD
srequirements mrd validate <file.json>      # Validate MRD structure

# TRD commands
srequirements trd generate <file.json>      # Generate markdown from TRD
srequirements trd validate <file.json>      # Validate TRD structure
Generate Options
srequirements prd generate input.json -o output.md    # Custom output path
srequirements prd generate input.json --no-frontmatter # Without YAML frontmatter
srequirements prd generate input.json --margin 1in    # Custom page margin
srequirements prd generate input.json --mainfont Arial # Custom font
Check Options (PRD only)
srequirements prd check input.json          # Human-readable completeness report
srequirements prd check input.json --json   # JSON output for programmatic use
Examples
# Validate and generate markdown
srequirements mrd validate examples/agent-platform.mrd.json
srequirements mrd generate examples/agent-platform.mrd.json

srequirements prd validate examples/agent-control-plane.prd.json
srequirements prd generate examples/agent-control-plane.prd.json
srequirements prd check examples/agent-control-plane.prd.json

PRD Completeness Check

The srequirements prd check command analyzes a PRD for completeness and quality, providing:

  • Overall score (0-100%) and letter grade (A-F)
  • Section-by-section breakdown for both required and optional sections
  • Specific recommendations prioritized by severity
Scoring

The completeness check evaluates:

Section Weight What's Checked
Metadata 10% ID, title, version, status, authors
Executive Summary 10% Problem statement depth, proposed solution, outcomes
Objectives 10% Business objectives, product goals, success metrics with targets
Personas 10% Number of personas, completeness of goals/pain points
User Stories 10% Acceptance criteria coverage, persona/phase linkage
Requirements 10% Functional/non-functional count, essential NFR categories
Roadmap 10% Phases with deliverables, success criteria, goals
Optional sections 30% Assumptions, out of scope, tech architecture, UX, risks, glossary
Example Output
