Learning check · before you start

What do you already have in place?

A few quick questions, so you can skip the steps you have already done. Each one has a line explaining what it means. Not sure, or never heard of it? Choose “Not yet / not sure”: that is where most firms start, and the playbook walks you through it.

  1. Have you named three jobs for Claude Cowork, a reviewer for each, and chosen which Claude plan the firm will use?

    Cowork is Claude working as an agent: it works through files, a browser and connected apps and hands back finished work, rather than chatting. Good first jobs are document-heavy and low-stakes. Team and Enterprise plans give an admin console and business data terms.

  2. Have you written down where client data stands, which single folder Cowork may use, and whether it must ask before each action?

    Client-data position: on business plans Anthropic's commercial terms apply; on personal plans you check the training setting. The working folder is one dedicated folder you copy work into, never the whole file server. Manual approval makes Cowork pause before each action.

  3. Is Cowork already installed and working in one folder, linked to no more than two low-risk apps?

    A connector links Cowork to another app. Start with low-risk ones such as your calendar or a scratch document folder, connected through a restricted login, and leave practice management, ledger write access and sending until much later.

  4. Have two people already run a pilot with a log of measured time saved?

    A pilot is a trial of about four weeks with two people, such as a manager and a senior, on two or three easy-to-review jobs. The log records each task, what was corrected and the time saved, timed rather than guessed.

  1. Step 1: Decide what Cowork is for in your firm

    Done when: You have three named jobs, a reviewer for each, and a plan chosen.

    Your task write down three document-heavy, low-stakes jobs Claude Cowork could take off your team, name who reviews the output of each, and choose a plan.

    How to do it, and what to read

    Be clear on what you are buying: Claude working as an agent through files, a browser and connected apps, then handing back finished work, not a chatbot. Write down three document-heavy, low-stakes jobs it would take off your team, and who would review the output of each. If you cannot name them, wait. For a firm, choose a Team or Enterprise plan rather than personal accounts, because those give you an admin console for connectors and business data terms. Check current pricing on Anthropic’s site before you commit.

    Claude Cowork is an AI agent: rather than answering questions in a chat, it works through files, a browser and connected apps and hands back finished work. A senior wants to buy it this week as a handy chatbot for quick questions. What do you do first?
    Three of your staff already pay for their own personal Claude accounts. You are now setting up Claude Cowork, Anthropic's AI agent, for the whole firm. Which plan do you choose?
  1. Step 2: Settle your data position before anyone logs in

    Done when: Your data position, working folder and approval mode are written down.

    Your task before anyone logs in, write down your client-data position, the one working folder Cowork may use, and who approves its actions.

    How to do it, and what to read

    Answer three questions in writing. What is your client-data position: on business plans Anthropic’s commercial terms apply, and on personal plans the training setting has to be checked. Which folders may it touch: create one dedicated working folder and copy work into it, never your whole client file server. Who approves actions: start on manual approval, so it pauses before each one. Then check the answers against your privacy obligations (the Privacy Act, UK GDPR or your US rules) and your engagement letters.

    AI agents like Claude Cowork can either pause for your approval before each action (manual approval) or act on their own. Which mode do you start the firm on?
    Before switching on Claude Cowork, an AI agent, you have written down three things: how client data is protected, which folder it may use, and who approves its actions. What do you check those answers against before anyone logs in?
  2. Step 3: Install it and connect only what is safe

    Done when: Cowork runs against the working folder with no more than two low-risk connectors.

    Your task install the Claude desktop app, connect your working folder, give Cowork one real first job (such as a comparison table from three PDFs), and add only low-risk connectors.

    How to do it, and what to read

    Install the Claude desktop app, connect the working folder, and give it one real first task, such as building a comparison table from three PDFs, so you see how manual approval works. Add connectors one at a time, starting with your calendar and a scratch document folder. A connector inherits the permissions of the account you connect it with, so use a restricted user. Leave your practice management system (Xero Practice Manager, FYI, AccountKit or whatever you run), ledger write access and any send permission until much later.

    You are connecting Claude Cowork, an AI agent, to the firm's calendar. A connector gets the same access as the user account you connect it with. Which account do you use?
  3. Step 4: Run a four-week pilot with two people

    Done when: The pilot log shows which jobs worked, with measured time saved.

    Your task pick two people and two or three easy-to-review jobs, run Cowork for about four weeks, and keep a shared log of what it did, what you corrected and the time it saved.

    How to do it, and what to read

    Pick two people, such as a manager and a senior, and two or three jobs that are easy to review: month-end prep packs, workpaper summaries, meeting notes turned into file notes, or letters drafted from your own templates. Run it for about four weeks. Keep a shared log for every task: what it did, what you corrected, and the time it saved, timed rather than guessed. When one job works reliably, write how you want it done as a skill, so every session follows your format.

    During your trial of Claude Cowork, an AI agent, it is getting workpaper summaries right every time. Cowork lets you save written instructions for a job, called a skill, so it follows your format every time. What do you do next?
  4. Step 5: Write a one-page policy from what the pilot found

    Done when: A one-page Cowork policy exists and Cowork is on your AI tools register.

    Your task once the trial is done, write a one-page Cowork policy from what it found, and add Cowork to your firm's register of AI tools.

    How to do it, and what to read

    Write the policy after the pilot, once you know the real questions. Keep it to one page: what data may go in, which connectors are approved, the approval mode required, and the review rule that nothing Cowork produces reaches a client until a person has read it end to end. Add Cowork to your AI policy’s tools register, and check your engagement letter tells clients you use AI tools and how the work is reviewed.

    You have written a one-page policy for using Claude Cowork, an AI agent, in your firm. What else should you check about what clients are told?
  5. Step 6: Train the rest of the team on proven jobs

    Done when: Everyone has used Cowork on a proven job, and the first usage review is done.

    Your task train the rest of the team on the jobs the trial proved, using the skills you wrote, and book a usage review for a month after rollout.

    How to do it, and what to read

    Onboard everyone else on the jobs the pilot proved, using the skills you built, rather than letting each person experiment from scratch. Run one “watch me do it” session for anyone who wants it, and expect a spread: some will run with it, some will need more time. Keep the whole firm on manual approval until the team has months of supervised use behind it. A month in, review usage: who uses it, for which jobs, and whether the review rule is holding.

Frequently asked questions

What plan does a firm need for Claude Cowork?

Cowork comes with every paid Claude plan, but a firm should use Team or Enterprise. Personal plans have no central admin, so you cannot control which connectors staff switch on or see what has been connected. Check Anthropic’s current pricing before you buy.

Is client data safe in Cowork?

It depends on the setup. Cowork only reaches the folders and connectors you grant, so the risk is mostly over-broad access, over-permissioned connectors and skipped review. A business plan, one dedicated working folder, manual approval and a review rule deal with most of it.

How long does a Cowork rollout take?

The technical setup is an afternoon. Settling your data position, a pilot of about four weeks, the policy and training the rest of the team take six to eight weeks in all.
