10 Claude Code Commands Every Beginner Should Know

Claude Code can do far more than answer coding questions. It can understand your codebase, review changes, modify files, and help manage complex development tasks directly from your terminal.

The challenge for new users isn’t learning Claude Code itself — it’s knowing which commands actually improve your workflow. A small set of commands can dramatically reduce repetitive work, provide better project context, and make AI-assisted development significantly more effective.

In this article, we’ll explore 10 Claude Code commands every beginner should know and how each one fits into a real-world development workflow.

Starting Every Project with /init

One of the first commands you should learn is:

/init

This command creates a CLAUDE.md file in your project.

The file acts as persistent project memory and provides Claude with important context about your codebase. Rather than repeatedly explaining architectural decisions, coding standards, naming conventions, or framework preferences, you can define them once inside this file.

A typical CLAUDE.md might contain instructions such as:

- Use SwiftUI for all UI development.
- Follow MVVM architecture.
- Prefer async/await over completion handlers.
- Add documentation comments to public APIs.

Prior to using project instructions, developers often had to repeat the same context every session. The /init command eliminates that repetition and ensures Claude consistently follows project-specific guidelines.

Discovering Available Commands with /help

When learning Claude Code, it’s useful to explore the available command set.

/help

This command displays supported commands and their usage information.

For beginners, it serves as a quick reference guide whenever you encounter unfamiliar functionality.

Instead of searching documentation, you can immediately view command descriptions directly inside the terminal.

Customizing Your Workspace with /statusline

Claude Code allows you to customize the terminal status line.

/statusline

One particularly useful configuration is:

/statusline show model name and context percentage with a progress bar

This transforms the status area into a live dashboard.

You can monitor which model is currently active, track remaining context capacity, and observe session usage without interrupting your workflow.

For long coding sessions, visibility into context consumption becomes increasingly valuable.

Understanding Stored Project Context with /memory

As Claude learns project-specific instructions, it is useful to inspect what information has been stored.

/memory

This command displays project memory and active instructions.

At this point, Claude may already be following rules defined through your CLAUDE.md file.

Using /memory allows you to verify that important project conventions are present and correctly configured.

This is particularly useful when working across multiple repositories with different coding standards.

Reviewing Your Codebase with /code-review

One of the most powerful beginner-friendly commands is:

/code-review

This command asks Claude to analyze your code and provide actionable feedback.

At a high level, Claude can identify:

• Potential bugs

• Security concerns

• Code smells

• Maintainability issues

• Performance bottlenecks

Consider a SwiftUI project containing complex state management logic.

Running:

/code-review

may uncover unnecessary view updates, duplicated business logic, architectural inconsistencies, or opportunities to simplify your implementation.

Prior to AI-assisted reviews, developers typically relied solely on peer reviews or manual inspection. The /code-reviewcommand provides immediate feedback directly within your development workflow.

Rather than replacing human code reviews, it acts as an additional layer of analysis that can catch issues early and help maintain code quality as projects grow.

Monitoring Usage with /cost

AI-assisted development often involves significant token consumption.

To monitor usage, Claude Code provides:

/cost

This command displays session usage statistics and associated costs.

For developers using Claude extensively throughout the day, cost visibility helps identify workflows that may be consuming excessive context or generating unnecessary requests.

Tracking usage also helps teams better understand AI development expenses over time.

Switching Models with /model

Different tasks benefit from different models.

Claude Code allows model selection through:

/model

This command displays available models and allows you to switch between them.

For example, a larger reasoning model may be ideal for:

• Architecture design

• Refactoring strategies

• Complex debugging

A lighter model may be sufficient for:

• File generation

• Documentation updates

• Simple coding tasks

Choosing the appropriate model helps balance capability, speed, and cost.

Clearing Context with /clear

As conversations grow, context can become cluttered with information that is no longer relevant.

When switching tasks, use:

/clear

This command clears the current conversation context while keeping you inside the project.

For example, after spending an hour debugging networking code, you may begin working on UI animations.

Rather than carrying unrelated debugging context into the next discussion, /clear provides a clean slate.

This often improves response quality and reduces unnecessary context consumption.

Troubleshooting with /doctor

If Claude Code behaves unexpectedly, the diagnostic command can help identify issues.

/doctor

This command performs environment checks and verifies that your Claude Code installation is functioning correctly.

Common issues it can help diagnose include:

• Authentication problems

• Configuration errors

• Environment setup issues

• Missing dependencies

For beginners, it is often the fastest way to identify setup problems without manually inspecting configuration files.

Configuring Terminal Integrations with /terminal-setup

The final command every beginner should know is:

/terminal-setup

This command assists with terminal integration and environment configuration.

Depending on your shell and operating system, Claude Code can enable additional workflow enhancements and improve terminal interactions.

Running this command early in your setup process helps ensure you are taking advantage of available integrations.

A Recommended Beginner Workflow

Once you become familiar with these commands, a typical development session might look like this:

/init
/statusline
/code-review
/cost
/clear

First, initialize project instructions. Next, configure your status line for visibility into model and context usage. Review your codebase for improvements, monitor session costs, and clear context whenever switching to a new task.

This workflow establishes a strong foundation for productive AI-assisted development.

Summary

Claude Code becomes significantly more effective when you understand the commands that shape your development workflow.

Commands such as /init and /memory help establish project context. /code-review provides automated code analysis. /statuslineand /cost offer visibility into usage and resource consumption. Meanwhile, /clear, /doctor, and /terminal-setup help maintain an efficient development environment.

Rather than treating Claude as a simple chat interface, these commands allow you to integrate it directly into your daily engineering workflow and maximize the value of AI-assisted development.
