Here's how Week 3 goes
For two weeks you've packed the window by hand; this week you build a place that comes pre-packed.
Week 0's tour marked the Projects door "Later" and promised you'd build one in Week 3. This is that week: a Project is a place, and you build yours today.
The re-explaining tax
Every fresh chat starts empty, so the setup falls on you, again and again.
Tap everything you find yourself typing or re-attaching each week, and watch the minutes add up.
What do you retype? Tap all that apply.

Tap items on the left and watch what the re-explaining costs you.
Your Week 1 instructions carry a few lines into every chat. A Project carries a whole lane's worth into every chat you open inside it.
Anatomy of a Project
The place holds exactly two things, and each does a different job.
How to behave in this lane
You met the system prompt in Week 1. This is yours: voice, audience, format, and standing rules, written once for one slice of your work.
What to know
Reference files every chat inside can read: the partner list, a style sample, the program one-pager. Each file gets checked before it goes in: nothing that identifies a scholar or family.
Every chat inside starts with both already in the window.
Build one
Pick the lane where you pay this tax most often and build the place today.
- Pick one lane of your work. A program, a partner cycle, a report you own. Coaches: a campus-support lane works well (office contacts, resource guides, style samples; never scholar records). One lane, one Project.
- Create the Project. In Claude, open Projects in the left sidebar, choose New Project, and name it for the lane.
- Write the instructions. Fill the template below and paste it into the instructions box on the Project's own page.
- Add 2–3 knowledge files, checked first. Upload them from the same Project page, and open each one before it goes in: aggregates and internal material only, nothing identifying a scholar or family, and nothing confidential to a partner or funder. No files handy? Build with instructions only and add them later; the Project works without them.
- Run your first task inside it. Two more before the week ends; the Your turn box below shows how.
Fill the brackets, paste it into your Project's instructions, and keep the last line word for word.
You support [your role] at DC CAP, a college-access nonprofit in Washington, DC.
Work in this Project is [the lane: what you produce here and who it serves].
[Audience: who most drafts are for.]
[Voice: two or three plain adjectives, or point at a knowledge file that shows it.]
[Format: what done looks like, including length and what to lead with.]
[Standing rules: anything true of every task in this lane.]
Never include anything that could point to one scholar or family; describe situations without identifying details.
Here is a Project built for a lane that really exists: updates on this AI program to KPMG, the funder behind it. You briefed this same update by hand in Week 2; here the setup is already standing. Its instructions read, in part: "Drafts here are for our funder's program team. Voice: warm, professional, direct. Format: short email that leads with what shipped." Knowledge holds the program one-pager and the last two updates. Watch what a two-line ask gets back.
Hello [contact name],
Week 3 opened Monday: every DC CAP team is building its first Claude Project, week three of the eight-week program. Weeks 0 through 2 stay open for anyone catching up after the July pause, and the capstone window closes September 25. Happy to walk you through the site any time.
[Your name]
The ask was two lines. The audience, the voice, the program dates, and the format came from context already standing in the Project. Your lane works the same way: a report you own, a partner cycle, a recurring update.
- Open your new Project and bring a real task from your lane.
- Ask in two lines, the way you'd ask a colleague who already knows the background.
- Read the draft against your instructions and knowledge. Where it missed, sharpen the instructions once, and every future chat inherits the fix.
Keep it true
A Project keeps whatever you put in it, including the parts that stop being true.
Claude reads an old file with the same confidence as a fresh one, and nothing in the answer looks wrong.
Say a knowledge file saved last cycle still lists last year's preference deadline. What happens to the drafts in this Project?
Show what happens →
Every draft cites last year's deadline, confidently, until someone notices. Nobody typed the wrong date this month; the file did, in every window the Project opened. The fix takes a minute: delete the old file, add the current one, and date-stamp it.
Four habits keep a Project honest:
What you can do now
A Project is a place. Next week you write a Skill, a method you load on demand, and you'll use the two together.
Two of the 4Ds carried this week:
Delegation
You chose the lane, and the knowledge worth handing over, and left the rest out.
Diligence
You gated every file, named an owner, and set the rhythm that keeps the place true.
This is your own check that the week landed. It stays in your browser — nobody else sees it.
Support, whenever you need it
Bring your Project to Preston's office hours, 9–10 AM ET any weekday: the instructions you wrote, or the draft that came back better because of them. Extension exercises land on this site every few Fridays.
Under the hood
Skip it and lose nothing. Three questions people usually ask about Projects.
What exactly loads into the window inside a Project?
The Project's instructions and knowledge files sit in the window before your first message arrives, alongside Claude's own standing instructions and your personal ones. The rest fills the way you learned in Weeks 1 and 2: your messages, your attachments, the conversation so far. Knowledge takes up room in the window, so a lean set of current files serves you better than a big archive. Load a big archive anyway and Claude stops loading everything and starts searching your files, pulling in only the parts that look relevant to each ask.
How is a Project different from my instructions for Claude?
Your instructions for Claude travel into every chat: a few lines about who you are and how you like output. Project instructions apply only inside their lane and go much deeper, and since Claude sees both inside a Project, keep the personal ones general and let the Project carry the specifics. Memory is different again: a few stable facts about you in every chat, while a Project carries a whole lane, only inside its own door.
Can my team share one?
Where the workspace allows shared Projects, several people can work inside the same standing context, and the whole team stops re-explaining at once. Sharing multiplies the payoff and the stale-file risk together, which is why Week 5 treats curation as a team job with a named owner. For now, build yours solo and get the habits down.
