sdd-plan

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.
