When I first started learning Vibe Coding, there were three high-frequency concepts that were easy to confuse: System Prompt, Skill, and Workflow. Later, through practice, I gradually clarified that the essence of Vibe Coding is not about writing code, but about "leading a team." You can imagine that you have hired a remote programmer (AI), and these three elements are your management tools: System Prompt (Job Description) is the qualitative definition for the AI. You don't need to repeat "who you are" in every instruction, but rather set its technology stack preferences (e.g., only writing Python), coding style (e.g., enforced type checking), and communication principles through the System Prompt. Function: Reduce communication costs and establish behavioral benchmarks. Workflow (SOP/Workflow) is the process control for the AI. It’s not just about telling it "what to do," but also specifying "in what order to do it." For example: read the document > write tests > implement code > run validation. You can achieve your ultimate goal by calling multiple Skills. Function: Prevent the AI from skipping steps and ensure delivery quality. Skill is the specific execution permission granted to the AI (e.g., network access, file read/write, database queries). Why has Skill recently gained attention? On one hand, the capabilities of AI Agents are expanding daily, and on the other hand, the modular and shareable nature of Skills makes them more disseminable. Reusable: Once you write a Skill for "querying Etherscan," it can be directly mounted in any conversation or model. Shareable: Developers can package and share Skills, allowing users to use them without needing to understand the internal logic, plug-and-play. The essence of Skill is to transform the AI from a "text generator" into an "interface caller" that can interact with external systems. In fact, efficient Vibe Coding is essentially a process of system integration: Use System Prompt to standardize employee quality; ...
