| Term | Primary Question It Answers | Example in Lesson Planning |
|---|---|---|
| Prompt | What should be done this time? | Prepare a 40-minute lesson plan for first-year middle school students, including discussion activities |
| Skill | What approach should be used for this type of task? | First verify student baseline, then allocate time, and finally check materials and final products |
| Tool | What specific operations can be performed? | Read data, create files, render presentation pages |
| Model Context Protocol (MCP) | How do applications connect to external services according to shared rules? | Connect to a service that provides course material query capabilities |
These concepts can be used together, and which ones are needed for each task depends on the goal, existing capabilities, and data sources. When several blocks of material are provided directly, an additional MCP connection is usually unnecessary.
An Agent can organize model judgment and tool operations to advance tasks; a Workflow describes the steps and their sequence. Skills provide methods, and MCP standardizes communication, but neither replaces tools or execution permissions.
