# Why Do You Need Training Input?

Training Input is your agent's "job description." Through training input, you tell the agent who it is, what it should do, and how to do it. This information is permanently retained, so you don't need to repeat it in every conversation.

Training Input typically includes:

- Role definition: what role the agent plays (e.g., "content operations assistant," "competitive analyst")
- Task scope: what the agent is responsible for
- Output format: structure and length of each output
- Style preferences: tone, vocabulary, voice
