Evolution Over Frameworks: Building Your Own Spec-Driven Development

Rather than adopting external SDD frameworks, the author advocates building custom implementations that evolve with your learning and changing needs. As LLM tools like Claude Code update frequently (new releases every 1-2 days), owning your methodology gives you the flexibility to adopt innovations on your own timeline rather than waiting for framework maintainers. For teams developing agentic software systems, this self-evolution capability becomes critical to staying aligned with fast-advancing tools and best practices.
