How SDD, Skills, and OmO Are Redefining Software Development in the AI Era

In the AI era, the author argues that developers should mitigate the influence of individual large models to increase controllability, much like reducing the role of luck in personal growth.

1. OmO – Oh My OpenAgent AI Programming Assistant

OmO (formerly oh‑my‑opencode) is an open‑source plugin for the OpenCode AI coding tool that turns it into a virtual development team composed of eleven specialized AI agents. The processing model changes from a single request handled by one AI to a request that OmO automatically schedules across multiple agents in parallel, dramatically improving efficiency.

2. Skills – Agent Plugins for Expert Knowledge

Skills, translated as “agent skills,” function like VS Code extensions: they are markdown files that can include executable scripts or templates, allowing AI agents to reuse expert knowledge without generating everything from scratch. Well‑crafted Skills save tokens by avoiding redundant generation.

3. SDD – Spec‑Driven Development

Spec‑Driven Development (SDD) – also called specification‑driven or normative‑driven development – means structuring all specifications. For AI, the more precise and standardized the natural‑language description, the better the model’s understanding and output.

The development focus shifts from line‑by‑line coding to designing and describing precise specifications, allowing AI to generate optimal solutions automatically.

4. Impact on Developers and Management

Experienced architects benefit because they can encode their expertise into Skills, offsetting speed disadvantages against younger developers. The need to concentrate on low‑level implementation diminishes, while attention moves to designing standards and specifications. This is advantageous for technical management but poses a threat to junior developers.

5. Remaining Barriers

AI safety : Financial institutions hesitate to adopt AI without robust security guarantees.

Model cost : Large‑model expenses remain high; small companies may use external APIs (e.g., Deepseek), whereas large enterprises must build internal deployments, sometimes costing more than hiring humans.

Recent price reductions for models like Deepseek are expected to alleviate these obstacles.

Conclusion

The clear path forward is to quickly master AI tools and develop multidimensional Skills to stay competitive in the evolving software development landscape.
