GSI-Protocol is an AI-powered SDD workflow that transforms any requirement into production-ready code through four structured phases — powered by Gherkin, Structure, and Implement.
// Features
Every aspect of GSI-Protocol is designed to eliminate the friction between idea and production code.
Works seamlessly with your existing AI assistant. No lock-in, no migration required.
Architecture design is independent of programming language — TypeScript, Python, Go, Rust — it works everywhere.
Execute the complete 4-phase development cycle with a single /sdd-auto command.
Built-in Gherkin support turns business requirements into living documentation and executable specs.
GSI-Protocol automatically detects your project's tech stack, conventions, and existing patterns. Architecture decisions adapt to what you already have — no manual configuration needed.
Mirrors real team workflow: PM → Architect → Engineer → QA, each phase with a clear responsibility.
// 4-Phase Workflow
Each phase has a clearly defined role, input, and output. No ambiguity, no guesswork.
Converts your requirement into a structured Gherkin feature file with Given/When/Then scenarios.
Designs a language-agnostic architecture document from your Gherkin spec, defining modules and interfaces.
Generates production-ready source code based on the architecture document, respecting your project's conventions.
Verifies the implementation against every Gherkin scenario and generates a conclusion report.
