Lesson 4 of 5 · 10 minutes · Module 2: Put Claude to work
Keep your instructions in one place
If you write the same kind of thing again and again, you shouldn’t have to explain yourself every time. In this lesson you’ll write instructions once, see what changes, and find out where Claude keeps them.
You need
- A Claude account
- A job you do often, like a notice, an email or a post
- About ten minutes
A narrated walkthrough of this lesson is coming. The steps below cover everything in it.
Step 1 of 6
Do the job with no instructions
First, let’s see what Claude does on its own. We asked for a short notice for the allotment gate, and it gave us a cheerful notice, in capitals, with no sign-off.

Step 2 of 6
Write your instructions
Instructions are just how you want every reply done. Ours has three rules: plain British English and under 70 words, a fixed sign-off, and never invent a date, time or price. Write yours for your own job. Keep them short, and about the general job, not one task.
The prompt · works in Claude (Instructions for Claude, or project instructions)You help the committee of Maple Street Allotment Society write notices for members. - Write in plain British English, friendly and short: under 70 words. - Sign off every notice "The Committee". - Never invent a date, time or price. If a detail is missing, write [TO CONFIRM] in its place.CheckpointYou’ve got a short set of instructions for your own job.
Step 3 of 6
See where Claude keeps instructions
Claude has two places for them. “Instructions for Claude” is account-wide, so click your initials in the lower left corner, choose Settings, and write them under Instructions for Claude. They apply to all your conversations. Project instructions only apply to chats inside one project, which suits a single job like ours.

- Project instructions: only chats in that project
CheckpointYou know the difference between account-wide and project instructions.
Step 4 of 6
Make a project
A project is a workspace with its own chats and knowledge, where you can upload documents, give context and set instructions. Claude’s help page says free accounts can create up to five. Its plans page lists Projects under Pro, so if you can’t find them on your account, just use Instructions for Claude, or paste your instructions at the top of a chat as we do next.

CheckpointYou’ve made a project and added your instructions, or you’ve got them ready to paste.
Step 5 of 6
Do the job again
Now run the same job with your instructions in place. We pasted ours at the top of the chat as a stand-in for a project, which gives every chat in it the same instructions. The notice came back shorter, signed “The Committee”, just as the instructions said.
The prompt · works in ClaudeInstructions for this chat: You help the committee of Maple Street Allotment Society write notices for members. - Write in plain British English, friendly and short: under 70 words. - Sign off every notice "The Committee". - Never invent a date, time or price. If a detail is missing, write [TO CONFIRM] in its place. Task: Write a short notice for the allotment gate about the autumn work day on Saturday 24 October, 10am to 1pm. Bring gloves.The reply we got on 2026-10-09, unedited. Read our reply.
Screenshot captured 9 October 2026. - No instructions: no sign-off, a long cheerful notice
- The committee’s instructions
- Signed "The Committee", as the instructions say
CheckpointThe reply follows your instructions.
Step 6 of 6
Test a job with gaps
Now give it a job with details missing. We left out the time, the order deadline and the price for a compost order. Claude put [TO CONFIRM] in each gap, as we asked, but it also added a line telling people to say who’ll collect their bags if they can’t come, which we never gave it. Delete anything you didn’t say, or add a rule against it.

Steps 3 and 4 are Anthropic’s public help pages; step 5 is our own page built from the real prompts and replies. The chat, Settings and project screens are behind a login, so they have no screenshot yet. For step 5 and step 6 we pasted the instructions at the top of the chat rather than using a project; the replies are in outputs/.
