description	SpecCrew PM Requirement Modeling Skill. Applies ISA-95 Stages 1-3 for business domain analysis, WBS decomposition, and module ordering. Produces .module-design.md as interface contract for downstream PRD generation. Second step in PRD workflow.
tools	Read, Write, Glob, Grep

Skill Overview

ISA-95 business modeling and module decomposition. Produces .module-design.md as the interface contract for PRD generation.

Trigger Scenarios

• Clarification completed (.clarification-summary.md exists)
• Complex requirements requiring ISA-95 analysis
• Multi-module system requiring decomposition

Input Parameters

Parameter	Type	Required	Description
iteration_path	string	Yes	Path to iteration directory
clarification_file	string	No	Path to clarification summary (default: {iteration_path}/01.product-requirement/.clarification-summary.md)

Methodology Foundation

Applies ISA-95 Stages 1-3 as structured analysis framework:

Stage	Purpose	Output
Stage 1: Domain Description	Boundary, actors, glossary	Domain model
Stage 2: Functions in Domain	WBS decomposition	Function map
Stage 3: Functions of Interest	MoSCoW prioritization	MVP scope

PM Stage Content Boundary

DO NOT include: API definitions, DB structures, code snippets, technical terminology. These belong to Feature Designer or System Designer.

AgentFlow Definition

REQUIRED: Before executing this workflow, read the XML workflow specification: speccrew-workspace/docs/rules/agentflow-spec.md

---

Output Checklist

• .clarification-summary.md verified (prerequisite)
• ISA-95 Stage 1 complete (Domain Description)
• Checkpoint A passed (domain boundary confirmed)
• ISA-95 Stage 2 complete (Functions in Domain)
• ISA-95 Stage 3 complete (Functions of Interest)
• Checkpoint B passed (MVP scope confirmed)
• Checkpoint C passed (complete analysis confirmed)
• Module list defined
• Dependency matrix created
• Implementation phases determined
• Module decomposition confirmed with user
• .module-design.md created
• .checkpoints.json updated via script

---

Constraints

Must do:

• Verify .clarification-summary.md exists before starting
• Use 3 checkpoints (A/B/C) for progressive user confirmation
• Define clear module boundaries with minimal coupling
• Use update-progress.js for JSON files

Must not do:

• Skip user checkpoints in complex mode
• Include technical implementation details
• Create circular module dependencies
• Manually write JSON files

Diagram Format Rule (MANDATORY)

• All diagrams MUST use Mermaid syntax (graph TB, graph TD, graph LR, etc.)
• ASCII art diagrams are FORBIDDEN
• Reference mermaid-rule.md for compatibility

Template

• Module design document MUST follow templates/MODULE-DESIGN-TEMPLATE.md structure
• All 10 sections are required
• Fill template with analyzed data from ISA-95 stages
