OpenSpec (Spec-Driven Development) Failed My Experiment — Instructions.md Was Simpler and Faster
📰 Dev.to AI
OpenSpec's Spec-Driven Development approach failed an experiment due to complexity, while a simpler Instructions.md file achieved faster results
Action Steps
- Evaluate the complexity of your project to determine the best approach
- Consider using a simple Instructions.md file for smaller projects
- Experiment with Spec-Driven Development frameworks like OpenSpec for larger projects
- Assess the results and adjust your approach accordingly

There’s a lot of discussion right now about how developers should work with AI coding tools. Over the past year we’ve seen the rise of two very different philosophies: 1. Vibe Coding — just prompt the AI and iterate quickly 2. Spec-Driven Development — enforce structure so AI understands requirements Frameworks like OpenSpec are trying to formalize the second approach. Instead of giving AI simple prompts, the w
