ACTUI Follow-Up: Submenus and Image Management

Quick Follow-Up After publishing the initial ACTUI article, I kept developing the tool. I started using it regularly and shared it with my team. Some feedback came in, and I naturally improved things during my free time. This is a quick update on what changed. What Changed Submenu Structure The original flat menu worked for a demo but felt cluttered with more features. I restructured the interface into three main sections: ...

Testing Spec-Kit: Building a Functional Container TUI in 2.5 Hours

Introduction: Theory Meets Practice In my previous article about GitHub Spec-Kit, I explored the theoretical foundations of spec-driven development: why structured AI workflows matter for compliance, auditability, and team collaboration. I discussed the high-level concepts of audit trails, liability, and how spec-kit transforms “vibe coding” into a rigorous, documented process. Today, I’m sharing something different: a raw, unfiltered hands-on experience building a real tool from scratch using spec-kit. This is a chronological journey documenting what actually happened when I let spec-kit drive the development process from constitution to working code. ...

GitHub Spec-Kit: Why Structured AI Development Beats Vibe Coding

Introduction: Spec-Driven Development vs. Vibe Coding If you’ve been working with AI coding assistants, you’ve probably experienced what some call “vibe coding”, throwing prompts at an LLM and hoping for the best. Sometimes it works brilliantly. Other times, you end up with code that technically runs but doesn’t align with what you actually needed, or worse, introduces architectural decisions that create technical debt down the road. Spec-Driven Development (SDD) flips this approach on its head. Instead of starting with code and documenting later (if at all), you begin with comprehensive specifications that define the what and why before anyone, human or AI, writes a single line of code. The specification becomes the single source of truth, guiding implementation and ensuring alignment across the entire team. ...
