Your portable context system for any AI.
The difference between an AI trained on all the worlds data and one thats trained on yours.
Context isn't a feature inside your AI.
🐿️ It's the layer underneath it.
Take your context with you between agents and sessions. Store it in files you can read and own for life. Your world of context will start growing as soon as you make this choice.
Context is everything you hear, say and do to make things happen in your life.
Your AI is powerful. It just doesn't know what you're trying to do, who you're working with, or what you decided last week. That's not an AI problem. That's a your context problem.
A walnut is a unit of structured context.
We didn't force this metaphor. The kernel of a walnut is shaped like a brain. Vascular bundles act as transport networks. Nature already built it.
my-startup/Every walnut is different
Plain markdown. Frontmatter links everything. On your machine. Portable between any AI.
A squirrel runtime that orients your agent to your world
We inject [email protected] into every session. It reads your walnut, loads your context, and teaches the agent how to work with you — not just for you.
Load
Every session starts with your context. The squirrel reads your walnut — key.md, now.md, tasks — and frontloads it into the agent. No re-explaining.
▸ key.md identity loaded ▸ now.md state loaded ▸ tasks.md 3 active, 1 urgent ▸ log.md last entry 2h ago 🐿️ ready — what are we working on?
Work
Use the skills during your session or the agent calls them itself. The squirrel catches decisions, tasks, and insights in a running stash — nothing gets lost.
Save
#1 featureSave is the whole point. It gives every session a checkpoint. Routes decisions to the log, updates state, dispatches context to other walnut. Your walnut compounds.
🐿️ saved — checkpoint 3 4 decisions → log 2 tasks added 1 dispatch → [[simon-beard]] next: updated zero-context: ✓
Each ecosystem application varies slightly. The runtime is open source — fork it and refactor it for your own agent stack.
