aiskillstore PRD to App Spec Converter
Transform Product Requirements Documents (PRDs) into structured XML application specifications optimized for AI coding agents.
When to Activate This Skill
- Convert a PRD to app spec format
- Generate XML specification from requirements document
- Transform technical PRD for agent consumption
- Prepare documentation for AI coding agent
- Create app_spec.txt from existing PRD
What This Skill Does
Converts developer-focused PRDs (with code snippets, TDD plans, implementation details) into declarative XML specifications that AI coding agents can consume more effectively.
Input: PRD with technical details, code examples, architecture decisions
Output: Structured app_spec.txt in XML format
How to Execute
Run the /convert-prd workflow, which provides:
- PRD file location (prompts if not provided)
- Section-by-section extraction and transformation
- Pydantic models → database schema conversion
- Implementation code → feature descriptions
- Epics/tasks → numbered implementation steps
- Test assertions → success criteria
- Final XML output with validation
Core Transformations
| PRD Has | App Spec Gets |
|---|---|
| Function implementations | Feature descriptions |
| Pydantic field validators | Data constraints in prose |
| Try/except patterns | Error handling requirements |
| Test assertions | Success criteria |
| CLI commands | API/command summaries |
| Directory structure | Technology stack context |
Output Template Structure
<project_specification>
<project_name>...</project_name>
<overview>...</overview>
<technology_stack>...</technology_stack>
<core_features>...</core_features>
<database_schema>...</database_schema>
<api_endpoints_summary>...</api_endpoints_summary>
<implementation_steps>...</implementation_steps>
<success_criteria>...</success_criteria>
</project_specification>
Key Principle
- PRD: Shows HOW (implementation details)
- App Spec: Describes WHAT (requirements and expectations)
The app_spec tells an agent WHAT to build without dictating exact implementation.
