Digital Speed advocates moving beyond risky vibe coding—where developers simply prompt AI to generate code—toward Spec-Driven Development (SDD). This method uses GitHub's open-source Spec Kit to enforce detailed specifications before any implementation. The tool generates structured markdown files like a Constitution and Specification to establish clear intent, aiming to prevent the bugs and maintainability issues inherent in vague AI prompting.

SDD separates intent from code, creating a shared context for teams and AI agents. The process involves a strict sequence: generating a spec, clarifying ambiguities, planning technically, and breaking down tasks. Digital Speed uses this with Claude Code and GitHub's CLI, creating pull requests with full documentation before implementation. This ensures every decision is explicit and reviewable, unlike vibe coding's assumption-driven chaos.

The result is a directory of generated artefacts, from a Checklist to a detailed Plan, culminating in an `implement` command for the LLM. Teams then deploy the feature branch through CI/CD for QA. While SDD requires upfront documentation work, proponents argue it yields more predictable, maintainable output than purely generative approaches. The method formalizes an industry best practice for successful product launches.
