What it is
A chat window forgets you. A workspace is Claude Code or Codex working inside a folder of your own documents: it reads them first and writes down what it learns.
| Compare | Chat window | AI workspace |
|---|---|---|
| Knows your business | Only what you paste in | Reads your folders |
| Learns from corrections | Forgets next chat | Writes the lesson down |
| Does the work | Text to copy | Files the finished document |
The folder structure
Plain folders and markdown files. Numbered stages set the order; a table of contents tells the AI where everything is.
- your-business/
- ├── CLAUDE.md
- The rules
- ├── INDEX.md
- Table of contents
- ├── 00_inbox/
- New documents
- ├── 01_knowledge/
- One page per client, process and product
- ├── 02_drafts/
- Work in progress
- ├── 03_review/
- Waits for a person
- ├── 04_final/
- Approved
- └── .env
- Keys, never read
Rules that make it improve
Loads at the start of every session. One line turns every correction into a permanent lesson.
# Rules- Read INDEX.md first.- When I correct you, add the lesson below.- Nothing moves to 04_final without me. # Lessons- Client emails: first names, no exclamation marks.
Skills
Saved routines the AI runs on request.
/tidy
Files loose documents, fixes names and updates the table of contents.
/train
Reads your new work and updates its knowledge and lessons, for you to approve.
/draft-reply
Drafts a client email from your templates and leaves it for review.
Connections
Reach the systems you already use.
MCP connectors
Let the AI use an app you have, like email, files or a CRM, with your approval.
Public data
SEC filings, FDIC bank data, Federal Reserve rates, pulled on request.
A small database
Your clients, jobs or prices in one table the AI can query.
API keys
Passwords for programs, kept in a .env file the AI is blocked from opening.
Gates and checks
Rules ask; gates enforce.
- PermissionsIt asks before editing, sending or running anything new.
- HooksScripts that always run: block .env, stop a draft with an SSN.
- Review foldersNothing reaches a client until a person moves it.
- Version historyEvery change saved, so anything can be undone.
Where it runs
Whichever editor you use, only your company's Claude or Codex account does the AI work.
Our default
VS Code
Free, from Microsoft, and usually already approved by IT.
- Official Claude Code or Codex extension only
- Workspace Trust on, as it ships
With its AI off
Cursor
Fine with its own AI switched off: left on, it sends code to Cursor's servers.
- Tab, chat and indexing off
- Workspace Trust turned on: it ships off
Simplest
Claude app
The Code tab in the Claude desktop app. Nothing else to install.
- No editor to approve
Ask your IT provider before installing anything on a company computer.
Where the method comes from
- Interpretable Context Methodology: Folder Structure as Agentic Architecture (opens in a new tab)Jake Van Clief and David McDermott, arXiv, March 2026Numbered folders and plain markdown files can stand in for complicated agent frameworks on step-by-step work, and keep every step readable by the people reviewing it.
- LLM Wiki (opens in a new tab)Andrej Karpathy, April 2026Let the AI compile your raw sources into a markdown wiki it maintains itself, with an index it reads first and a log of every change, so knowledge compounds instead of being found again each time.
- STAIR: Structure Aware Information Retriever (opens in a new tab)IBM Research, arXiv, September 2026Using a document's table of contents as the map found the right section 82.6% of the time, ahead of every other method tested; keyword search managed 59.5%.
Questions
- Do we need to know how to code?
- No. You talk to it in plain English, and the folders and rules are ordinary documents.
- Is our client data safe in it?
- On a business plan nothing trains on your data, full SSNs, bank, account and card numbers, and health information stay out, and nothing leaves without a person approving it.
- What does it cost to run?
- The AI seat you'd buy anyway: Claude Team from $20 a person a month includes Claude Code. VS Code is free.
