How Luna Works
Spec-Driven Development

Spec-Driven Development:
Build Software Right from the Start

Luna Base transforms requirements into precise technical specifications, then orchestrates 20 AI agents to build production-ready software with complete traceability.

Why We Choose a
Spec-Driven Approach?

Traditional software development fails because of the "translation gap" between human ideas and machine implementation. We built Luna Base on the philosophy of Spec-driven development to eliminate this ambiguity.

Precision over Guesswork

Instead of AI "hallucinating" code based on vague prompts, Luna operates on strict blueprints derived from your PRD. Every decision is intentional, every implementation is deliberate.

End-to-End Traceability

Every line of code, every infrastructure decision, and every test case can be traced back to a specific requirement. You know exactly why a piece of software exists and what purpose it serves.

Scalable Consistency

Whether you have one developer or a hundred AI agents, Spec-Driven Coding ensures uniform standards and logic across the entire codebase, making software delivery predictable and reliable.

How Luna Base Orchestrates Spec-Driven Development

Our 6 specialized Copilots work in harmony, guided by executable specifications to deliver production-ready software.

1
Requirements Analysis

Generating Technical Specifications

The Blueprint

Luna starts by ingesting raw Product Requirement Documents (PRD) and User Stories. It refines this input, automatically translating business needs into detailed technical specifications. These act as immutable blueprints for the engineering agents, ensuring no context is lost.

Business Analyst Agent: Validates logic and identifies gaps in PRD
Spec Writer Agent: Converts user stories into strict API schemas and data models
2
System Design

Architecture Driven by Requirements

Design Based on Validated Requirements, Not Assumptions

Every architectural decision is mathematically derived from the specifications. System architecture is designed based on validated requirements, ensuring optimal patterns and technology choices.

System Architect Agent: Evaluates design patterns against technical specifications
Technology Selection Agent: Chooses tech stack that best meets specified constraints
Infrastructure Design Agent: Plans server resources for stated performance needs
3
BDD Implementation

Spec-Driven Coding

Execution with Behavior Driven Development (BDD)

Six development agents write code that precisely implements the blueprints. Agents don't just "write code"; they translate specifications into behavior. Using principles of Behavior Driven Development (BDD), the agents understand what the code must do before writing how to do it.

Frontend Agent: Builds UI components exactly as specified in design specs
Backend Agent: Implements business logic strictly per requirement docs
API Agent: Creates interfaces that match generated Swagger/OpenAPI specs
4
TDD Quality Assurance

Validation & Traceability

Validation via Test-Driven Development (TDD)

QA agents employ Test-Driven Development (TDD) where test cases are derived directly from the requirements before or during the coding phase. Nothing gets deployed without validation. The specifications act as the "Test Oracle." If the code doesn't match the spec, the build fails.

Test Strategy Agent: Generates test scenarios from technical specifications
Automation Engineer Agent: Writes automated scripts to validate all endpoints
Quality Validator Agent: Ensures strict requirement compliance
5
Infrastructure as Code

Spec-Driven DevOps

Infrastructure Defined by Software Requirements

Just as code is driven by specs, your infrastructure is provisioned based on the strict requirements of the application, ensuring security and performance are never afterthoughts.

DevOps Engineer Agent: Generates Infrastructure as Code (IaC) scripts (Terraform/K8s) that match architectural blueprints
Security Compliance Agent: Scans infrastructure against security specs defined in requirement phase
Cloud Resource Agent: Optimizes resource allocation based on performance specifications
6
Orchestration

Orchestrated for Success

Keeping the Context Alive

The Orchestration Copilot coordinates all 20 agents, ensuring requirements flow through every phase without loss of context or intent. Every decision is preserved throughout the lifecycle.

Project Coordination Agent: Manages workflow across all copilots
Context Management Agent: Maintains traceability links between PRD, Spec, Code, and Tests
Decision History: Preserves every choice throughout the lifecycle

Frequently Asked Questions

Everything you need to know about Spec-Driven Development and how it powers Luna Base

Is Spec-driven development different from "Vibe Coding"?

Yes, they are fundamentally different. Vibe Coding (often associated with LLMs) relies on intuition, iterative prompting, and "feeling" out the code, which is great for prototyping but prone to errors. Spec-driven development, utilized by Luna Base, relies on strict technical specifications and blueprints. It creates a structural, deterministic process suitable for enterprise software delivery, ensuring that the final output matches the initial business intent precisely.

Which Luna Base products use Spec-driven development?

Spec-driven development is the core engine behind the entire Luna Studio platform. It starts with the Requirements Copilot for generating specifications and flows through the Architecture, Coding, Testing, and DevOps Copilots. This unified approach allows teams to utilize Luna for the entire SDLC or specific phases, always backed by the power of specification-first engineering.

How does Spec-Driven Development improve Software Traceability?

Spec-driven development creates an unbreakable link between business goals and code. By deriving every artifact (architecture, code, tests) from a central technical specification, teams achieve 100% Traceability. This means you can instantly track a line of code back to the User Story that requested it, or see which tests validate a specific business requirement, significantly reducing technical debt and compliance risks.

Can Spec-Driven Development work with Agile and BDD/TDD?

Absolutely. Spec-driven development acts as the high-level strategy that empowers Agile, Behavior Driven Development (BDD), and Test-Driven Development (TDD). In Luna Base, the specs define the "Behavior" (BDD) and generate the "Tests" (TDD) automatically. This allows Agile teams to move faster because the "Definition of Done" is mathematically defined by the specs, removing ambiguity from sprints.
