Every stage produces an artifact that can be reviewed and consumed by the next stage.Every stage includes a Human-in-the-Loop review gate.
01 — Governance Setup
INITIALIZATION
Establishes the project context, user information and governance connection.
Output: Project and governance configuration
02 — Manual Input Preparation
ELICITATION
Human stakeholders provide structured project information, features and design preferences using predefined templates.
Output: Structured project inputs
03 — Compliance Generation
AUDIT
The Compliance Agent analyzes the available project information, identifies applicable compliance conditions and generates the compliance artifact.
Output: Compliance document
04 — PRD Generation
SPECIFICATION
The PRD Agent analyzes project inputs and compliance requirements, identifies ambiguities and generates the Product Requirements Document.
Output: Product Requirements Document
05 — Design Documentation
SYNTHESIS
The Design Agent translates approved requirements into sitemap structures, mockups, UI concepts, components and CTA strategies.
Output: Design documentation
06 — UI Generation via Antigravity Stitch
INTEGRATION
Approved design documentation is passed through Antigravity Stitch via Model Context Protocol (MCP) to generate UI/HTML and related design assets.
Output: UI and design assets
07 — Data Flow Diagram Generation
TOPOLOGY
The DFD Agent converts the approved requirements and design context into a structured data-flow model and rendered DFD.
Output: Data Flow Diagram
08 — Architecture Generation
CORE ARCHITECTURE
The Architecture Agent uses the approved design and DFD inputs to generate the system architecture documentation.
Output: System architecture
09 — Module Generation
MODULARIZATION
The Module Agent decomposes the approved architecture into service and module definitions.
Output: Module definitions
10 — Task Breakdown
ORCHESTRATION
The Task Agent transforms the accumulated artifacts into an engineering execution plan.
Output: Development task plan
11 — Test Generation & Categorization
VERIFICATION
The Test Agent generates test cases and separates them into appropriate AI-executable and human-review categories.
Output: Test suite and test classification
12 — Change Analysis & Artifact Update
SOVEREIGN GATEWAY
When requirements change, the Update Analysis Agent assesses the potential impact and identifies affected artifacts.Human approval is required before the updated artifacts proceed through the workflow.
Output: Change-impact analysis and updated artifacts
13 — Code Generation
COMPILATION & SYNTHESIS
Once the preceding artifacts have been reviewed and finalized, the workflow hands the engineering context to Antigravity / Codex for code generation.
Output: Generated application code
