When to use a reusable skill instead of another one-off prompt.
Prompts are useful for one-time tasks. Skills are better for repeated work.
A prompt usually mixes context, instruction, style, and expected output in one message. That is fast, but it breaks down when you need the same process tomorrow, next week, or across a team.
A skill separates the workflow from the moment. The markdown file defines the operating procedure. Your prompt supplies the current project context.
Use a prompt when the request is small or unusual. Use a skill when the task has a repeatable method: writing comparison pages, validating an app idea, auditing a page, debugging a route, or planning a content engine.
The AI Marketing Operator Pack and Debugging & Code Quality Pack are good examples: each skill turns a messy task into a repeatable workflow with a quality bar.
