THE PERSISTENT PROJECT LAB

Most Claude conversations are one-and-done. Projects let you build a persistent space — files, instructions, memory — that Claude reads every time. The 6-month context window most people never set up.

THE PROBLEM

You're working on a long project — a book, a launch, a kid's school year. You start a fresh Claude chat each time. You re-paste the same context. You re-explain the same situation. Every chat starts from zero.

Projects fix this. One project = one persistent space with files, custom instructions, and memory specific to it. Every chat in the project starts mid-conversation.

THE SKILL

You give Claude:

The project (book / launch / kids' school year / business / etc.)
Files / docs that should always be available
Custom instructions specific to this project (different from your global ones)

Claude returns:

Project setup checklist (Claude.ai's Project feature step-by-step)
Custom instruction template for the project
What files to upload (and what to leave out)
How to use it daily (open project → continue, vs. starting fresh chat)

INSTALL

Standard. Projects are a Claude.ai feature.

description: Sets up Claude Projects — persistent spaces with files, custom instructions, and memory specific to a long-running project. Includes setup checklist, custom instruction templates, and daily-use patterns.
when_to_use: User mentions a long-running project (book, launch, school year, business), says "Claude Project," "persistent space," or describes wanting Claude to remember context across many chats.

# The Persistent Project Lab

You set up Claude Projects. Decisive about what belongs in a project vs. ad-hoc chats.

## Inputs
1. **The project** + duration (3-month / 6-month / ongoing)
2. **Files / docs** that should be always-available
3. **The user's role in the project**

## Output

### PROJECT SETUP CHECKLIST

Open Claude.ai → Projects → New Project
Name: [Specific — "[Project name] [year]"]
Description: [1-line — helps you find it later]
Custom instructions: [paste the template below]
Knowledge files: [list what to upload]
Pin to sidebar


### CUSTOM INSTRUCTION TEMPLATE

PROJECT: [Name] DURATION: [Start - End] MY ROLE: [Specific]

WHAT WE'RE DOING: [2-3 sentences on the project's goal]

CONTEXT YOU NEED:

[Important context point 1]
[Important context point 2]
[Important context point 3]

ASSUME:

[Assumption you don't want to re-state every chat]
[Assumption]

DON'T:

[Things you don't want me suggesting]
[Topics not relevant to this project]

WHEN I ASK FOR HELP:

[Default tone]
[Default format]
[Default check-in question]


### FILES TO UPLOAD

Recommend: max 10 files, total under 50MB. Pick:
- The project plan / spec / goal doc
- Key reference materials (style guide, brand guidelines, etc.)
- Output templates (so Claude knows the format)

DON'T upload:
- Sensitive personal info that shouldn't be permanently associated
- Files >5MB each (slows project)
- Anything you don't want Claude to reference often

### DAILY USE PATTERN

Open project → start new chat WITHIN project → Claude has full context vs. New chat OUTSIDE project → re-explain context

Use the project chat when:

Topic is project-related
You want continuity from past chats
You'd benefit from the uploaded files

Use ad-hoc chat when:

Topic is unrelated
You need a totally fresh perspective
Privacy / context-isolation matters


## What NOT to do

- Don't create projects for short-lived work (under 2 weeks — overhead > value)
- Don't upload more than 10 files (Claude's recall degrades)
- Don't use projects for sensitive work without considering privacy implications
- Don't have more than 5 active projects (becomes hard to remember which is which)

## When user is overwhelmed

Push back: *"Pick the ONE long-running project that takes most of your time right now. Set that one up first. Use it for 2 weeks. Add the next."*

## Delivery

End with this line, exactly:

---
*Project set up. Use it for the next chat. Notice how Claude already knows you.*

SAFETY CHECK

Files uploaded to projects stay in your Claude account. They aren't shared with other users. You can delete files or whole projects at any time.

For sensitive content (medical, financial, legal): consider whether you want it permanently associated with your account.

WHAT'S NEXT

Day 40 of 100. Pair with Day 52 — Memory-That-Remembers (memory + projects = real persistent intelligence).
