๐ŸŽฏ Introduction

Running claude once is coolโ€”but the real magic happens in interactive mode. This is where Claude transforms from a simple question-answering tool into your AI pair programmer ๐Ÿค–, maintaining context across conversations, understanding your project deeply, and executing complex multi-step workflows.

What Makes Interactive Mode Different? ๐ŸŒŸ

| One-Shot Mode | Interactive Mode | |---------------|------------------| | Single question โ†’ answer โ†’ done | Continuous conversation with memory | | No context between commands | Context builds with each exchange | | Start from scratch every time | Resume where you left off | | Good for quick tasks | Perfect for complex workflows |

In this Claude CLI interactive mode guide, you'll master the commands and workflows that separate casual users from power users. You'll learn slash commands that control your sessions, keyboard shortcuts that save hours, and conversation strategies that get better results from Claude.

By the end of this tutorial, you'll work with Claude CLI like a seasoned pro, building context strategically and solving problems faster than ever. ๐Ÿ’ช

Let's dive into interactive mode mastery.


๐Ÿš€ Launching Interactive Mode

Interactive mode is your default workspace when using Claude CLI. It's where you'll spend most of your time.

Starting a Session

Navigate to your project directory and launch Claude:

cd ~/projects/my-app
claude

You'll see the Claude Code welcome screen:

Understanding the Interface

Your interactive session has three key areas:

๐Ÿ“Š Status Line (top):

  • Current model (Claude Sonnet 4.5)
  • Project name (from your directory)
  • Session start time

๐Ÿ“ Recent Conversations:

  • Quick access to previous sessions
  • Resume with /resume command
  • Automatic conversation history

โŒจ๏ธ Prompt (>):

  • Type questions, commands, or requests
  • Multi-line input supported (Shift+Enter)
  • Paste images directly (Ctrl+V)

Exiting Interactive Mode (Three Clean Ways)

| Method | Keyboard | When to Use | |--------|----------|-------------| | ๐ŸŸข Recommended | Ctrl+D at empty prompt | Normal exit | | ๐Ÿ”ต Command | /exit | Explicit shutdown | | ๐Ÿ”ด Emergency | Ctrl+C twice | Cancel operation first, then exit |

Pro Tip ๐Ÿ’ก: Always use Ctrl+D or /exit for clean shutdowns. This saves your conversation history properly.

  3. โœ๏ธ Text Editing: Ctrl+A/E/W/U, Opt/Alt+F/B - Edit prompts

๐Ÿ’ฌ Multi-Turn Conversation Strategies

Interactive mode shines when you build context strategically across multiple turns. Think of it like pair programmingโ€”the more Claude understands your project, the better the solutions. ๐Ÿค

Strategy 1: Progressive Context Building

Start broad, then narrow down:

Turn 1: > What does this project do?
Turn 2: > How is authentication handled?
Turn 3: > The JWT tokens are expiring too quickly. Why?
Turn 4: > Fix the expiration time to 7 days

Pattern: Project overview โ†’ Subsystem โ†’ Specific issue โ†’ Precise fix

Why this works: Claude builds a mental model of your project, with each turn adding specificity for more accurate final requests.

Strategy 2: Reference Previous Responses

Claude remembers the conversation. Reference earlier exchanges:

> Analyze the authentication flow
> Can you write tests for the flow you just described?

Key phrase patterns:

  • "Based on what you found earlier..."
  • "Like you explained before..."
  • "Following the same pattern you showed..."
  • "Using the approach from your previous suggestion..."

Strategy 3: Iterative Refinement

Don't expect perfection on the first try. Iterate in layers:

Turn 1: > Create a user profile component
Turn 2: > Add form validation
Turn 3: > Make the error messages more user-friendly
Turn 4: > Add loading states during form submission

Pattern: Feature โ†’ Enhancement โ†’ Refinement โ†’ Polish

Strategy 4: When to Start Fresh

Sometimes you need to clear context and start over:

Clear context when:

  • Switching to completely unrelated task
  • Claude seems confused by old conversation
  • You've gone down the wrong path
  • After solving a complex problem
  • Nearing token limits
> /clear
> Let's start fresh. I need to build a new feature for...

Token Management Strategies

Long conversations consume tokens. Manage them wisely:

Check usage periodically:

> /cost

Compact when nearing limits:

> /compact

Clear after completing tasks:

> /clear

Strategic summarization:

> Summarize what we've accomplished so far
> /clear
> Here's the context: [paste summary]
Now let's continue with...

Conversation Strategy Quick Reference

Five key strategies:

  1. ๐Ÿ“Š Progressive Context - Complex investigations, builds deep understanding
  2. ๐Ÿ”— Reference Previous - Iterating on solutions, maintains continuity
  3. ๐Ÿ”„ Iterative Refinement - Creating features, layers improvements
  4. ๐Ÿงน Start Fresh - Switching tasks, clears confusion
  5. ๐Ÿ’ฐ Token Management - Long sessions, avoids limits

๐Ÿ“ Working with Files in Interactive Mode

Claude CLI understands your project structure and can work with files intelligently. No more copying and pasting between terminal and editor! ๐ŸŽ‰

Reading Files (Three Approaches)

| Method | Syntax | When to Use | |--------|--------|-------------| | ๐Ÿค– Automatic | Ask naturally | Let Claude find relevant files | | ๐ŸŽฏ @-mention | @src/auth.js | Explicitly specify file | | ๐Ÿ“ฆ Multiple | @file1 @file2 | Compare or analyze together |

Automatic reading: Claude automatically reads relevant files when you ask questions:

> Explain what src/auth.js does

Claude reads src/auth.js and explains...

Explicit @-mentions: Reference files directly for precise control:

> Review @src/auth.js for security issues

Claude focuses specifically on that file...

Multiple files:

> Compare @src/auth.js and @src/api/auth.ts

Claude analyzes both files...

Editing Files Interactively (The Review Workflow)

Ask Claude to modify code, then review before applying:

> Add error handling to src/auth.js

Claude proposes changes:

Would you like me to apply these changes to src/auth.js?
(y/n/edit):

Your three options:

| Option | What Happens | When to Use | |--------|--------------|-------------| | โœ… y | Apply immediately | Changes look good | | โŒ n | Reject changes | Not what you wanted | | ๐Ÿ“ edit | Review in editor first | Want to see full context |

Creating New Files

> Create a utility function file at src/utils/dates.js
  with functions to format dates

Claude generates the file and writes it:

โœ“ Created src/utils/dates.js
Added functions:
  - formatDate(date, format)
  - parseDate(string)
  - isValidDate(date)

Would you like me to write tests as well?

File Path Handling (All Forms Work)

Claude understands multiple path formats:

| Path Type | Examples | When to Use | |-----------|----------|-------------| | ๐Ÿ“ Absolute | /Users/dev/projects/my-app/src/auth.js | Unambiguous | | ๐Ÿ“‚ Relative | src/auth.js or ./src/auth.js | From project root | | ๐ŸŽฏ @-mention | @src/auth.js | Explicit reference | | ๐ŸŒ Glob | src/**/*.test.js | Multiple files |

Glob patterns for bulk operations:

> Review all TypeScript files in src/api
> Analyze @src/**/*.test.js

File Operations Quick Reference

Five common operations:

  • Read single file: Explain @src/auth.js
  • Read multiple: Compare @src/auth.js @src/api/auth.ts
  • Edit existing: Add error handling to src/auth.js
  • Create new: Create utility file at src/utils/dates.js
  • Bulk analysis: Review all test files

๐ŸŽฎ Real-World Workflow Example

Let's walk through a complete debugging session to see these concepts in action. This is how you'll actually use Claude CLI in daily work. ๐Ÿ”ง

Scenario: React Component Re-rendering Bug

You have a performance issue in your app. Let's solve it with Claude CLI using proper multi-turn strategy.

Turn 1: Start the Investigation ๐Ÿ”

> I have a React component that's re-rendering too often.
  Let me show you the component file.

Claude: I'd be happy to help! Please share the component file, and I'll analyze the rendering behavior.

> @src/components/UserProfile.js

Claude reads the file and responds:

Looking at UserProfile.js, I can see several potential causes:

1. Line 15: useEffect with no dependency array runs on every render
2. Line 23: Inline arrow function in onClick creates new function each render
3. Line 31: Object literal in style prop creates new object each render

These are causing unnecessary re-renders. Would you like me to fix them?

What happened: Progressive context buildingโ€”Claude now understands the problem deeply.

Turn 2: Apply Fixes โš™๏ธ

> Yes, please fix all three issues

Claude: I'll optimize the component to prevent unnecessary re-renders.

โœ“ Applied changes to src/components/UserProfile.js

Changes made:
1. Added dependency array to useEffect
2. Wrapped click handler with useCallback
3. Moved style object outside component
4. Added React.memo for props comparison

Would you like me to show you the diff?

> Yes

Claude shows before/after diff...

> Looks good. Can you also add comments explaining the optimizations?

Claude: Adding explanatory comments...

โœ“ Updated src/components/UserProfile.js with comments

What happened: Iterative refinementโ€”started with fix, then enhanced with comments.

Turn 3: Verify the Fix โœ…

> Now help me verify this actually fixed the performance issue.
  What should I look for?

Claude: Here's how to verify:

1. Open React DevTools Profiler
2. Record a session while interacting with UserProfile
3. Look for reduced render count

Let me also create a simple performance test:

โœ“ Created src/components/UserProfile.test.js

This test verifies:
- Component only re-renders when props actually change
- Callbacks maintain stable references
- Style objects don't cause re-renders

Run: npm test -- UserProfile.test.js

What happened: Reference previous workโ€”Claude builds on the fixes to create tests.

Turn 4: Run Tests and Document ๐Ÿ“

Ctrl+B npm test -- UserProfile.test.js

โœ“ Command running in background

> While tests are running, can you document these optimizations
  in the component file as JSDoc comments?

Claude: Adding comprehensive JSDoc...

โœ“ Updated with JSDoc comments explaining:
  - Performance considerations
  - When re-renders occur
  - Memoization strategies

> /cost

Token Usage: 15,420 tokens
Remaining: 184,580 (92%)

> Perfect. Let me check the test results.

Claude: The tests passed! Your component is now optimized.

โœ“ All tests passed (3/3)
  - Prevents unnecessary re-renders
  - Maintains stable callback references
  - Style objects properly memoized

Would you like me to apply similar optimizations to other components?

What happened: Background execution + token managementโ€”worked efficiently.

Session Summary: In 10 minutes, you:

  • โœ… Identified 3 performance issues
  • โœ… Applied fixes with explanations
  • โœ… Created performance tests
  • โœ… Added documentation
  • โœ… Verified the solution

All without leaving your terminal.

โ“ FAQ

How do I see my conversation history?

When you start claude, recent conversations appear on the welcome screen. Use /resume to continue any previous conversation with full context restored.

Can I save and resume conversations?

Yes! Claude CLI automatically saves conversations. Use /resume to see recent sessions and continue where you left off. Conversations persist across terminal sessions.

What happens when I hit token limits?

Claude CLI will warn you when approaching limits. Options:

  1. Use /compact to summarize and compress context
  2. Use /clear to start fresh
  3. Start a new session with a summary of previous work

Check current usage anytime with /cost.

How do I clear context and start fresh?

Use the /clear command to remove all conversation history from the current session. Claude will have no memory of previous exchanges, giving you a clean slate for new tasks.

Can I use Claude CLI with multiple projects simultaneously?

Yes, but each terminal window is one session. Open multiple terminals for multiple projects:

# Terminal 1
cd ~/projects/frontend
claude

# Terminal 2
cd ~/projects/backend
claude

Each maintains separate context and conversation history.

How do keyboard shortcuts work on Windows vs macOS?

Most shortcuts are the same. Key differences:

  • macOS: Use Opt+F/B for word jumping
  • Windows/Linux: Use Alt+F/B for word jumping

What's the difference between /clear and /exit?

  • /clear - Removes conversation history but keeps session active. You stay in Claude CLI.
  • /exit - Ends the session entirely and returns to your shell.

Use /clear when switching tasks. Use /exit when you're done working.

Practice Challenge

Before moving on, try this 15-minute exercise:

  1. Start claude in one of your projects
  2. Use /status to check your setup
  3. Ask: "What does this project do?"
  4. Ask a follow-up question referencing Claude's response
  5. Try Ctrl+R to search your conversation
  6. Check /cost to see token usage
  7. Use /compact to compress the conversation
  8. Continue with a new question

Notice how context builds and Claude's responses become more precise. That's the power of interactive mode.
