The Foundation of Success: Universal Best Practices

Before we explore the team-specific strategies, it’s crucial to understand the fundamental principles that underpin successful collaboration with Claude Code:

• The Art of the Prompt: The quality of your output is directly proportional to the quality of your input. Be clear, specific, and provide as much context as possible. Think of yourself as a project manager delegating a task to a talented but literal-minded assistant.
• Iterative Collaboration: Don’t expect a perfect solution on the first try. Treat Claude Code as an iterative partner. Start with a simple prompt, review the output, and then refine your request with additional instructions. This back-and-forth process is where the magic happens.
• Embrace Autonomous Workflows: For many tasks, you can set Claude Code to work autonomously and check in periodically. This is especially effective for prototyping, writing tests, and other non-critical path activities. You’ll be amazed at what it can accomplish while you focus on other priorities.

Team-Specific Strategies for Maximum Impact

Data Infrastructure: Automating and Securing Your Data Pipelines

The Data Infrastructure team at Anthropic relies on Claude Code to manage the massive datasets that fuel their research and development. Their best practices are a masterclass in efficiency and security:

• The Power of Claude.md: Create a comprehensive Claude.md file in your project directory. This file should act as a “user manual” for Claude, outlining your team’s specific workflows, preferred tools, and coding conventions. A well-crafted Claude.md can transform Claude from a general-purpose assistant into a specialized team member.
• Security First: When dealing with sensitive data, always prioritize security. The Data Infrastructure team recommends using MCP servers instead of the BigQuery CLI to ensure that you have granular control over data access and permissions.
• Knowledge Sharing is Key: Regularly hold team sessions to share and demonstrate new Claude Code workflows. This not only helps to disseminate best practices but also sparks new ideas for how to leverage the tool in innovative ways.

Product Development: Building a Self-Sufficient Development Loop

The Claude Code team is at the forefront of using their own product to build, test, and deploy new features. Their best practices are a testament to the power of “dogfooding”:

• The “Test-First” Approach: One of the most effective ways to ensure code quality is to have Claude generate tests before it writes the actual code. This forces a clear definition of the desired functionality and makes it easier to verify the final output.
• Task Triage: Sync vs. Async: Develop an intuition for which tasks are best suited for asynchronous work and which require your direct supervision. Prototyping a new feature? Let Claude run wild. Fixing a critical bug in your core business logic? Keep a close eye on its work.
• Clarity is King: When working in a complex codebase with multiple components that have similar names, be extra specific in your prompts. The more context you provide, the less likely Claude is to get confused and the more you can trust it to work independently.

Security Engineering: Hardening Your Defenses with AI

The Security Engineering team at Anthropic uses Claude Code to proactively identify and mitigate security vulnerabilities. Their strategies are a blueprint for building a more secure software development lifecycle:

• Custom Slash Commands for the Win: Don’t be afraid to create your own custom slash commands to automate repetitive security tasks. The Security Engineering team has created over 50 custom commands to streamline everything from dependency scanning to vulnerability patching.
• Let Claude Take the Wheel: For complex security investigations, resist the urge to micromanage. Instead, provide Claude with a high-level goal and let it work autonomously. You might be surprised by the creative and effective solutions it comes up with.
• Documentation on Autopilot: Claude Code is a powerful tool for generating and synthesizing documentation. Provide it with a few writing samples and your preferred formatting, and it can create high-quality documentation that you can use in your wikis, READMEs, and other internal resources.

Data Science and ML Engineering: From Raw Data to Production-Ready Dashboards

The Data Science and ML Engineering teams use Claude Code to bridge the gap between research and production. Their best practices are a guide for anyone looking to turn data into actionable insights:

• The “Slot Machine” Strategy: For complex refactoring tasks, don’t be afraid to take a chance. Save your current state, let Claude work its magic, and if the result isn’t what you’re looking for, simply roll back and try again. Sometimes a fresh start is the fastest path to a solution.
• The Power of “Simpler”: If Claude provides a solution that is overly complex or difficult to understand, don’t hesitate to ask for a simpler approach. The model is often capable of generating more elegant and efficient solutions when prompted to do so.

API Knowledge: Navigating the Unknowns of a Large Codebase

The API Knowledge team is responsible for ensuring that Claude has access to the information it needs to answer user queries accurately. Their best practices are a must-read for anyone who works in a large and complex codebase:

• Embrace the “Beginner’s Mind”: When tackling a bug or investigating an incident in an unfamiliar part of the codebase, let Claude be your guide. It can help you ramp up quickly and make meaningful contributions without a lot of prior knowledge.
• Start Small, Think Big: Instead of overwhelming Claude with a massive amount of information upfront, start with the bare minimum and let it ask for more context as needed. This more natural, conversational approach can often lead to better results.

Growth Marketing: Automating Your Way to Success

The Growth Marketing team uses Claude Code to automate repetitive tasks and create sophisticated, multi-step workflows. Their strategies are a goldmine for anyone looking to do more with less:

• Identify Your Automation Opportunities: Look for tasks that are repetitive, rule-based, and involve tools that have APIs. These are the low-hanging fruit for automation with Claude Code.
• Divide and Conquer: For complex workflows, break them down into smaller, more manageable sub-tasks and create specialized sub-agents for each one. This makes it easier to debug problems and improves the overall quality of the output.
• Plan Before You Prompt: Before you write a single line of code, take the time to map out your entire workflow. This will help you to create a more comprehensive and effective prompt for Claude Code.

Product Design: From Static Mockups to Functional Prototypes

The Product Design team uses Claude Code to bridge the gap between design and engineering, turning static mockups into interactive prototypes with unprecedented speed. Their best practices are a game-changer for any design team:

• Don’t Go It Alone: The initial setup for Claude Code can be a bit challenging for non-developers. Don’t be afraid to ask for help from your engineering colleagues. A little bit of upfront investment will pay huge dividends down the road.
• The Power of the Paste: One of the most powerful features of Claude Code is the ability to paste images directly into the prompt. This allows you to turn static mockups into functional code with just a few clicks.
• Custom Memory for the Win: Create a Claude.md file with specific instructions on how you want Claude to behave. This is especially helpful if you have little to no coding experience, as it can help to guide the model and improve the quality of its responses.

RL Engineering: Supercharging Your Reinforcement Learning Workflows

The RL Engineering team uses Claude Code for everything from writing small features to debugging complex reinforcement learning algorithms. Their strategies are a must-read for anyone working in this cutting-edge field:

• The One-Shot Approach: For many tasks, it’s worth giving Claude a quick prompt and letting it attempt the full implementation in one shot. If it works, you’ve saved yourself a ton of time. If not, you can always switch to a more collaborative, back-and-forth approach.
• Checkpoint Your Work: When you’re experimenting with new ideas, it’s always a good idea to commit your work frequently. This makes it easy to roll back to a known good state if things go wrong.
