Dev Swarm Stage Prd

Stage 05 - PRD (Product Requirements Document)

Create a comprehensive Product Requirements Document that defines the complete product behavior, including functional requirements, non-functional requirements, user flows, acceptance criteria, and all specifications needed to guide development.

When to Use This Skill

• User asks to start stage 05 (prd)
• User wants to define product requirements or acceptance criteria
• User asks about functional or non-functional requirements

Your Roles in This Skill

See dev-swarm/docs/general-dev-stage-rule.md for role selection guidance.

Role Communication

See dev-swarm/docs/general-dev-stage-rule.md for the required role announcement format.

Pre-Stage Check

Before starting, verify previous stages:

1. Check if 00-init-ideas/ through 04-tech-research/ folders have content (not just .gitkeep)
2. If any previous stage is empty and has no SKIP.md:
   • Ask user: "Stage {XX} is not complete. Would you like to skip it or start from that stage first?"

Instructions

Step 1: Context Review

Read all files to understand the project:

• ideas.md
• 00-init-ideas/*.md through 04-tech-research/*.md - All markdown files

Step 2: Create Stage Proposal

General Rules: See dev-swarm/docs/general-dev-stage-rule.md → "Create Stage Proposal Rules" section.

If this stage is skipped (has SKIP.md), execute the next non-skipped stage's agent skill. Otherwise, create the file 05-prd/README.md with the following content:

2.1 Stage Goal

Brief the goal in 2-3 paragraphs:

• What this stage aims to achieve
• Why a comprehensive PRD is critical for successful development
• How this builds upon previous stages
• What deliverables will be produced

2.2 File Selection

Select files from these options based on project needs:

Core Requirements:

• functional-requirements.md - Detailed functional requirements describing what the system must do
• non-functional-requirements.md - Performance, security, scalability, and other quality attributes

User Experience & Flows:

• user-flows/ - User interaction flow diagrams

Quality & Validation:

• acceptance-criteria.md - Clear, testable criteria for each feature
• error-handling-and-edge-cases.md - How the system handles errors and boundary conditions

Data & Analytics:

• analytics-and-events.md - Events to track and metrics to collect

Compliance & Legal:

• compliance-and-legal-notes.md - Regulatory requirements and legal considerations

Dependencies:

• dependencies.md - External services, APIs, and third-party integrations

For each selected file, provide:

• Short description
• Why it's essential for this project
• Key information it should include

2.3 Request User Approval

Ask user: "Please check the Stage Proposal in 05-prd/README.md. Update it directly or tell me how to update it."

Step 3: Execute Stage Plan

Once user approves 05-prd/README.md:

3.1 Create All Planned Files

Create each file listed in the approved README:

• For .md files: Write comprehensive content based on insights from all previous stages
• For diagram folders: Follow dev-swarm/docs/mermaid-diagram-guide.md to create related diagrams files

Quality Guidelines:

• Base requirements on personas, user stories, MVP scope, and tech research findings
• Write functional requirements that are specific and testable
• Define non-functional requirements with quantifiable targets
• Ensure acceptance criteria use clear Given/When/Then format
• Include both happy path and error scenarios in user flows
• Incorporate any constraints discovered during tech research

3.2 Request User Approval for Files

After creating all files:

• Provide a summary of what was created
• Highlight key requirements and critical dependencies
• Ask: "Please review the PRD documents. You can update or delete files, or let me know how to modify them."

Step 4: Finalize Stage

Once user approves all files:

4.1 Documentation Finalization

• Sync 05-prd/README.md to remove any deleted files
• Ensure all files are complete and well-formatted
• Check that all diagrams render correctly

4.2 Prepare for Next Stage

• Summarize key requirements for reference in UX and Architecture stages
• Identify requirements that will impact UX design decisions

4.3 Announce Completion

Inform user:

• "Stage 05 (PRD) is complete"
• Summary of deliverables created
• Key requirements and constraints identified
• "Ready to proceed to Stage 06 (UX) when you are"

Stage Completion Rules

See dev-swarm/docs/general-dev-stage-rule.md for stage completion, commit, and skip rules.

Key Principles

• Make requirements specific and testable
• Include clear acceptance criteria
• Cover both happy path and error scenarios
• Support smooth transition to UX design
