Claude Code: The AI Operating System for Product Teams

Most product teams are using AI inefficiently - copying files into claude.ai (or ChatGPT), uploading the same research docs again and again, losing context between conversations.

Meanwhile, a smaller group has discovered something different: AI that lives in your file system, not your browser.

Think of it this way: claude.ai is where you talk to AI. Claude Code is where AI actually works with your files, folders, and real deliverables. It's not replacing chatbots - it's the layer underneath that makes them useful for actual product work.

I won’t cover how to install it - there are plenty of YouTube videos on that as well as the official Anthropic quick start guide.

Let’s dive into what the change is, and how it could help you.

Why this shift matters now

Few people know how to integrate AI into work that touches real deliverables - PRDs, research synthesis, competitive analysis, data, in a effective manner.

The shift happening now isn't from "no AI" to "AI assistant." It's from AI as app to AI as operating system.

Claude Code is the first mainstream example. It runs locally on your computer, connected to your actual files. It reads your PRDs, analyzes your research, edits documents, and remembers context across sessions.

Claude Code helps you do things. Think of it like this:

• Chat layer - Conversation and intent (your internal assistant, copilots, claude.ai)

• Workflow layer - Execution and action on real files (Claude Code)

• Governance layer - Context, access controls, compliance (your company's knowledge systems)

This newsletter issue is about that middle layer - the one that's quietly changing what "using AI at work" actually means.

What changes when AI moves into your workspace

Claude Code looks like a developer tool. But really, it requires a mindset shift.

Instead of uploading files to a cloud chatbot, you point Claude at your local folders. That single change unlocks capabilities PMs and execs should care about:

• File operations: Read, write, and edit documents directly. No more manual upload.

• Parallel processing: Run multiple Claude instances at once. One analysing competitor pricing, another synthesising interviews, another building a dashboard. All simultaneously.

• Custom reviewers: Build sub-agents that critique your work from different perspectives: UX, Engineering, Executive. Get feedback before you share with your team.

• Image analysis: Paste screenshots and mockups. Get instant design feedback.

If you can describe what you want in plain English, Claude Code can do it.

Chat + Code in action

Let me show you three real workflows: 1, synthesising user research, 2, getting multi-perspective PRD reviews, and 3, turning data into presentations. All running locally on my laptop with Claude Code working directly on the files.

1. Synthesising user research

Ask Claude AI: "Summarise this user feedback." It gives you broad themes from whatever you pasted.

With Claude Code, you point it at your entire folder and say:

"Read all files and create a table of the top 5 user frustrations, grouped by theme, with sample quotes."

It analyses every document - PDFs, text notes, screenshots - and outputs a structured summary ready for your strategy deck. No copying. No pasting. No context lost.

I ran this on some interview notes in my folder. To begin, Claude Code first established which interviews were in scope, then created top 5 user frustrations from that content.

So, the key point here is we achieved all of this by pointing Claude Code to a folder and guided it to complete these tasks - no loss of context and no need to upload attachments and file. It then created these docs and auto-saved them to the folder on my laptop.

2. Writing a PRD with multiple reviewers

Let’s assume we have a PRD, we want to have reviewed by three roles (UX, Eng and Execs). We can create a reusable agent that can be called to do this for you. You draft your PRD in claude.ai or Google Docs. Get the structure right, flesh out the details etc.

Then you open Claude Code and create three sub-agents. This is surprisingly easy.

The key point here is you can then use these over and over again for other tasks.

• UX_Reviewer - focuses on clarity and user flow

• Eng_Reviewer - checks technical feasibility and dependencies

• Exec_Reviewer - rewrites for strategic alignment

Once you have created the agents - task them with providing feedback on your document.

You prompt: “Each of you review the PRD and provide your feedback…”

Claude edits your actual file and shows you changes with different highlights. It's like having three expert reviewers - instantly, locally, before you share with stakeholders.

This is the difference between showing up to reviews with a first draft versus a fifth draft. Same time investment. Completely different level of confidence.

You can additionally prompt: "Each reviewer, add feedback inline to the PRD. Merge into one version with comments grouped by role."

3. Turning data into a presentation

If we have a data file, with some data on experiments we are running and want to see this reflected more visually.

You can tell Claude Code: "Use /Data/Q3_Experiments.csv to generate an interactive dashboard."

Claude builds the dashboard, converts it to slides, and saves everything to your folder. You open it in your browser - ready for your meeting.

The mindset of using AI like an operating system is important. This is where "AI for work" stops being a novelty and starts being really powerful.

Why this matters for PMs and execs

This is exactly what agentic work looks like in its early form.

Claude Code teaches a new skill - not coding, but AI orchestration. You're not writing commands. You're directing a team of digital colleagues.

For PMs, it's a glimpse of the next craft:

• Persistent memory replaces repetitive prompting

• Sub-agents replace ad-hoc reviews

• Context-rich file actions replace endless Google Docs chaos

For executives, it's an early signal:

• Chat interfaces will stay the front end

• Execution layers like Claude Code become the back end

• AI systems will integrate with your internal knowledge, compliance, and governance stacks

The teams who learn to manage both layers - interface and infrastructure - will shape how AI-native organisations actually work.

Not sure where to start or want to learn more?

I've been helping product teams set up Claude Code workflows - not as a coding tool, but as an AI operating system for product work.

I focus on your specific challenges: research synthesis, PRD reviews, competitive intelligence, data analysis.

AI work is becoming layered. Chatbots are how we talk to AI. Systems like Claude Code are how we work with it.

The PMs who learn both layers now will shape how AI-native organisations work tomorrow.
