What is Reqvire?

Reqvire is a lightweight, Git-native Requirements-as-Context framework that turns specifications into structured, AI-ready context: enabling smarter development, traceability, and consistent change management.

It unifies system modeling, requirements management, context engineering and AI-assisted development into a single workflow—providing complete traceability, intelligent automation, and faster delivery while staying fully aligned with your codebase.

Key Features

Requirements-as-Context

Create a structured, canonical source of truth for your project.
Reqvire provides a consistent context layer that AI tools can reliably query—so they always understand what needs to be built, where changes belong, and how system components fit together.

Requirements-as-Code

Evolve requirements from static documents into version-controlled, executable artifacts.
Reqvire keeps your system model alive in Git—no more lost specs, outdated docs, or knowledge locked in transient tickets.

Intelligent Engineering

Bring Model-Based Systems Engineering (MBSE) directly into your Git workflow:

• Specification-Driven Development
  Develop from requirements. Enforce clear specifications and generate code that stays tied to its originating requirements.

• Automated Traceability
  Maintain instant, bidirectional links between requirements, code, tests, and artifacts.

• Verification & Validation
  Track verifications, ensure coverage, and validate that implementations meet intended behavior.

• Smart Change Propagation
  Identify impacted parts of the system and help propagate requirement changes consistently across the model and codebase.

• Seamless Integration
  Works naturally with branches, pull requests, reviews, and CI/CD. No workflow disruption—just added intelligence.
