Developer explains differences between Skill, MCP, Workflow, Rules, and Memory

On 2026-10-31, an article titled 'Skill、MCP、Workflow、Rules、Memory 有什么区别' appeared on Juejin. The author, who moves between Claude Code, Codex, and Pi-Bolt on a regular basis, describes running into a recurring problem: sometimes all you want is help writing a page, yet the configuration surfaces a row of concepts before anything gets done, as if you had to pass an exam before visiting a service counter. The piece was written to disentangle these frequently conflated configuration terms. It works through real development tasks, such as implementing a page from a Figma design file, and explains what Skill, MCP, Workflow, Rules, and Memory each take responsibility for. This is the only report available so far, so the specific division of labor among the concepts and the article's conclusions remain to be fleshed out by later coverage.
