Your Business Brain
Write your business down once. Every session starts knowing it.
Bruno Ashford
The problem
On Monday it wrote in your voice. On Tuesday it had never heard of you.
Bruno Ashford
Why AI forgets
The context window is a desk
If it is not on the desk, Claude does not know it.
Every session starts with a clear desk
Files, messages and replies fill it
When it is full, quality drops
/context shows what is on it
Two kinds of memory
What carries over between sessions
CLAUDE.md
Auto memory
Who writes it
You
Claude
What it holds

Learnings and preferences

The handbook
What goes in your CLAUDE.md
1CompanyWho we are in one paragraph
2OffersWhat we sell and for how much
3ClientsWho we serve and who we do not
4VoiceConcrete rules, real examples
5Red linesWhat never happens
6Folder mapWhere everything lives
Guidance from Anthropic's docs
Keep the handbook lean
~200lines per CLAUDE.md, recommended ceiling
1rule per line
@imports for longer documents
Rules
Red lines, standards, quality bars
Three different jobs. Write them separately.
Red lines: must never happen
Standards: how we always do it
Quality bars: checked before you see it
Test every red line by breaking it
Guidance vs. enforcement
CLAUDE.md guides the agent. Permissions and hooks lock the door.
Bruno Ashford
Folders
If a new hire could find it, so can the agent
Structure is context you never have to type.
One folder per business area
Dates first: 2026-09-proposal.md
Originals never edited
A folder map in CLAUDE.md
Long sessions
Four commands that keep answers sharp
1/contextSee how full the desk is
2/compactSummarise and keep going
3/clearFresh start between tasks
4Handover noteSave decisions to a file
Your project
A tested company handbook
Write it, then prove it on three real tasks.
Loaded and visible in /context
Knows your client, offer and voice
Refuses two red-line tests
Under about 200 lines
Recap
Stop re-explaining your business. Write it down once, and let every session start from there.

Use ← → to move. The marker highlights text and the pencil draws on the slide; navigation locks while you annotate. Undo removes the last mark, Esc exits.
Stop re-explaining your business every morning. Write it down once and let every session start already knowing it.
