PRD Schema Implementation Plan

[ForestMars]

Overview

Following ADR-001 (#12), we need to implement the complete PRD processing pipeline. This issue tracks the implementation plan and dependencies.

Implementation Steps

1. PRD Schema Definition

• Define schema requirements
  • Required top-level fields
  • Standardized subobjects
  • User story format
  • Validation rules
• Create YAML schema definition
  • Use JSON Schema draft-07
  • Include all required fields
  • Add validation rules
  • Document schema

2. Example and Documentation

• Create example PRD
  • Follow defined schema
  • Cover all schema features
  • Include edge cases
• Publish schema and example
  • Version the schema
  • Create documentation
  • Add usage examples

3. Validation Strategy

• Evaluate validation options
  • Self-hosted validator
  • Third-party solutions
  • Integration with existing tools
• Implement chosen solution
  • Create validation pipeline
  • Add error reporting
  • Document validation process

4. AST Implementation

• Define AST schema
  • Map PRD concepts to AST nodes
  • Define relationships
  • Add validation rules
• Implement PRD to AST parser
  • Create parser logic
  • Add error handling
  • Add validation

5. TypeSpec Generation

• Implement AST to TypeSpec transformer
  • Map AST nodes to TypeSpec
  • Handle relationships
  • Add validation

Technical Considerations

Schema Definition

• Need to decide on user story format (Given/When/Then vs. As a/I want/So that)
• Need to define required vs optional fields
• Need to handle versioning

Validation

• Consider using existing JSON Schema validators
• Need to decide on validation error format
• Consider real-time validation in editors

AST Design

• Need to ensure AST can represent all PRD concepts
• Need to handle edge cases and invalid inputs
• Need to consider future extensibility

TypeSpec Generation

• Need to ensure generated TypeSpec is valid
• Need to handle all PRD concepts
• Need to consider TypeSpec best practices
