What problem does it solve?
This Skill prevents common AI development pitfalls like hallucinated APIs, context drift, and breaking existing functionality by enforcing a "plan-first" methodology. It ensures every development task begins with a detailed, validated specification, reducing rework and increasing reliability.
Core Features & Use Cases
- Staged Planning: For complex features, create high-level phase structures for early user approval before diving into detailed task breakdown.
- Detailed JSON Specifications: Generates precise JSON files with phases, file-level modifications, dependencies, and verification steps.
- Codebase Analysis Integration: Proactively uses codebase documentation (via
Skill(sdd-toolkit:doc-query)) for accurate, context-aware planning.
- Use Case: When starting a new feature like "Add JWT Authentication," use this skill to generate a comprehensive JSON spec, outlining database changes, service layer implementation, API integration, and testing, ensuring a clear roadmap before writing any code.
Quick Start
Verify sdd CLI is installed
sdd --help
Example: AI generates a markdown outline of phases for user approval.
(This is a conceptual step, the skill generates JSON based on user input)
After approval, generate the complete JSON specification
(This is the core output of the skill, e.g., specs/active/user-auth-001.json)
The specific command to generate the JSON is internal to the skill's logic.
