1. **Interactive mode** is for exploration and iteration - context carries forward. It's like having a conversation with someone who remembers what you've said up to that point.
2. **Plan mode** is normally for more involved tasks. Review before implementation.
3. **Programmatic mode** is for automation. No interaction needed.
4. **Four essential commands** (`/help`, `/clear`, `/plan`, `/exit`) cover most daily use.

As you add files and conversation, Copilot CLI's [context window](https://github.com/github/copilot-cli-for-beginners/blob/main/GLOSSARY.md#context-window) fills up. Several commands are available to help you stay in control:

```bash
copilot

> /context
Context usage: 45,000 / 128,000 tokens (35%)
Context usage: 62k/200k tokens (31%)

> /clear
# Wipes context and starts fresh. Use when switching topics
# Abandons the current session (no history saved) and starts a fresh conversation

> /new
# Ends the current session (saving it to history for search/resume) and starts a fresh conversation

> /rewind
# Opens a timeline picker allowing you to roll back to an earlier point in your conversation
```

> 💡 **When to use `/clear`**: If you've been reviewing `books.py` and want to switch to discussing `utils.py`, run `/clear` first. Otherwise stale context from the old topic may confuse responses.
> 💡 **When to use `/clear` or `/new`**: If you've been reviewing `books.py` and want to switch to discussing `utils.py`, run `/new` first (or `/clear` if you don't need the session history). Otherwise stale context from the old topic may confuse responses.

> 💡 **Made a mistake or want to try a different approach?** Use `/rewind` (or press Esc twice) to open a **timeline picker** that lets you roll back to any earlier point in your conversation, not just the most recent one. This is useful when you went down the wrong path and want to backtrack without starting over entirely.

#### Best Practices for Large Codebases

1. **Be specific**: `@samples/book-app-project/books.py` instead of `@samples/book-app-project/`
2. **Clear between topics**: Use `/clear` when switching focus

> **What if Copilot could automatically apply your team's best practices without you having to explain them every time?**

In this chapter, you'll learn about Agent Skills: folders of instructions that Copilot automatically loads when relevant to your task. While agents change *how* Copilot thinks, skills teach Copilot *specific ways to complete tasks*. You'll create a security audit skill that Copilot applies whenever you ask about security, build team-standard review criteria that ensure consistent code quality, and learn how skills work across Copilot CLI, VS Code, and the Copilot coding agent.
