Lesson 6 - Know what the agent can see

Terminal commands make context visible and intentional. Knowing what the agent can see helps you understand its results and decide when to start fresh.

In this lesson, you will:

  • inspect the context window with /context.
  • see how much of the window each part consumes.
  • reset a drifting conversation with /clear.

Inspect the context

  1. Run /context to inspect files, instructions, and conversation history.
  2. Check how much of the window each part is consuming.
  3. Run /clear to start fresh when the conversation has drifted.
  4. Add the right file back before you ask for another change.

Illustration of Copilot CLI output after running /context. A context window meter shows 61 percent used, split between conversation, files read, and instructions. A note suggests using /compact to summarize, or starting a fresh session, when running low.

/context shows exactly what is filling the context window and how much room is left. When you are running low, use /compact to summarize the conversation, or start a fresh session.

Summary and next steps

You can now see and manage what the agent knows. Continue to Lesson 7: Resume and go remote.
