What problem does it solve?

Spec-First SDLC provides a structured approach to transform human intent into traceable software artifacts. It reduces ambiguity, ensures design-before-code discipline, and provides a clear path from requirements to implemented software with review gates at each phase.

Core Features & Use Cases

• Intent-to-design flow: Claude produces High-Level Design (HLD), ADR-Lite, and executable implementation specs from an initial intent document.
• Traceability through artifacts: Links requirements to ADRs, design decisions, and implementation.
• Code generation & validation: Generates code and tests from the EIS and validated outputs.
• Use Case: A new project starts with a requirements document; the Skill guides through HLD, ADR-Lite, EIS, and code, with human reviews at each stage.

Quick Start

Prepare your Intent & Constraints document and optional design artifacts, then run this Skill. Claude will generate the High-Level Design, ADR-Lite, revised HLD, Executable Implementation Specification, and from that, code in src/ and tests in tests/. Review each phase before proceeding.
