Practical Orchestration: Spec-Driven Development Examples

The ultimate evolution of an AI-Driven Engineer is the transition from "Vibe Coding" (guessing and checking) to Spec-Driven Development (SDD). In this paradigm, you treat the specification as the primary product, and the implementation as a deterministic byproduct. This lesson explores how to use native agent capabilities to achieve production-grade velocity with near-zero logic gaps.


Example 1: The Project Constitution (CLAUDE.md)

The Scenario

You are managing a high-scale TypeScript project. Without strict rules, different AI agents (and even different developers) might introduce inconsistent patterns—mixing Functional and Class components, varying naming conventions for hooks, or choosing different libraries for state management. This "Inconsistency Debt" eventually breaks the build or creates maintenance nightmares.

The SDD Solution

You establish a Project Constitution via CLAUDE.md. This file serves as the "Guardrail for Autonomy," ensuring that every agent or subagent that enters the environment operates under the same legal framework of the codebase.

The "How" (Establishing the Truth):

  1. Rule Definition: CLAUDE.md specifies exactly how to write code: "Use Tailwind for styling," "Hooks must go in /hooks," "No default exports."
  2. Environment Sync: It includes "Task Scripts" (npm run build, npm run lint) so the agent knows exactly how to verify its own work.
  3. Commanding Logic: When a new agent starts, its system prompt forces it to read this constitution first.

Detailed Analysis: This is Spec-First engineering at the foundational level. By defining the "laws" of the project, you remove the need for repetitive prompting and ensure that the agent's autonomy is focused on solving problems, not deciding on syntax.


Example 2: The Four-Phase SDD Lifecycle

The Scenario

You need to add a "Multi-Tenant Subscription Gallery" to your platform. This is a high-risk feature involving database migrations, third-party API integration (Stripe), and complex UI state.

The SDD Solution

Instead of saying "Build me a gallery," you follow the Four-Phase Workflow: Research, Specification, Refinement, and Implementation.

The "How" (The Engineering Loop):

  1. Research: You command the agent to: "Research our existing Prisma schema and the Stripe 'Product' API. List potential integration conflicts."
  2. Specification: Based on research, the agent writes a BILLING_SPEC.md. This document outlines the schema changes, the API routes, and the security protocols.
  3. Refinement (The Interview): The agent uses the ask_user_question tool: "How should we handle graceful degradation if the Stripe webhook fails?" You answer, and the spec is updated.
  4. Implementation: Only after the spec is approved does the agent start coding. It uses the task tool to break the spec into 5 atomic, testable steps.

Detailed Analysis: This workflow eliminates the "Assumption Drift" common in vibe coding. By separating "Thinking" (Phases 1-3) from "Doing" (Phase 4), you ensure the AI builds exactly what is needed, the first time.


Example 3: Parallel Orchestration with Subagents

The Scenario

Your project needs a massive "Dark Mode" overhaul across 50 different components. Doing this in a single thread would hit token limits and likely result in inconsistent quality.

The SDD Solution

You act as the Agent Commander, using a Lead Agent to orchestrate multiple Subagents to work on the UI, the Theme Logic, and the Testing suite concurrently.

The "How" (Massive Parallelism):

  1. Decomposition: The Lead Agent analyzes the THEME_SPEC.md and identifies three independent domains.
  2. Delegation: It creates three subagents:
    • Subagent A (The Stylist): Updates CSS variables in the globals.css and individual component files.
    • Subagent B (The Architect): Updates the ThemeProvider context and the useTheme hook.
    • Subagent C (The Tester): Writes Playwright tests to detect "Visual Regressions" in both light and dark modes.
  3. Synthesis: The Lead Agent reviews the work of all three subagents, runs the full test suite, and performs a final git commit.

Detailed Analysis: This represents the "Lead Engineer" mindset. You aren't just writing code; you are managing a team of Digital Developers. This parallel approach scales your output by 3-5x without sacrificing the architectural integrity of the project.


Key Takeaway

Spec-Driven Development is about Authority. In vibe coding, the "vibe" is the authority. In SDD, the Document is the authority. By mastering the constitution, the four-phase loop, and subagent orchestration, you transform from a coder into an Architect of Autonomous Systems.
