FonteOS gives Claude Code persistent memory, project awareness, and session continuity — through a vault structure you clone, not a service you subscribe to.
You're re-explaining your world every time you open a new conversation. That's not a workflow — that's overhead.
Your mission, your projects, your priorities, your decisions. Every conversation starts cold. You spend the first 10 minutes rebuilding what Claude should already know.
No isolation means Claude mixes concerns between ventures, clients, or products. A question about one project pulls in noise from another. Signal degrades.
Dumping your notes into every session is expensive and slow. You're paying to re-teach, not to work. There's no structure — just bulk paste and hope.
FonteOS is a vault structure and a set of behavioral rules — written in plain markdown. Claude loads it automatically every session.
It's just markdown files and a CLAUDE.md. No install, no dependencies, no configuration wizard. Open the folder as an Obsidian vault or any markdown editor. Done.
git clone → open → doneClaude reads your world: mission, active projects, last session state. It cross-references your task manager, surfaces what's relevant, scopes to one project. The first run walks you through setup. Every run after that is instant.
/start → context loaded → work beginsAt the end of each session, /end saves your state: decisions made, work done, what's next. The next session reads that state and starts where you left off. No recap needed.
/end → state saved → cold start eliminatedEvery piece of context has a home. The structure tells Claude exactly what to load — and what to leave alone.
No feature bloat. Everything here exists because running multiple projects with Claude, without it, is painful.
Last session state is saved and reloaded automatically. Cold starts eliminated. Pick up exactly where you left off, every time.
Each project lives in its own spring with its own index and streams. Claude scopes to one project per session. No bleed-over, no mixed context.
Stream insights that recur 3+ times get promoted to Intelligence files — permanent, confidence-rated reference knowledge that outlives any session.
Claude writes freely to streams and inbox. Everything permanent — source, intelligence, spring indexes — requires human approval. You control what crystallizes.
The hierarchy means Claude loads ~5k tokens of context, not your entire vault. Targeted loading. 90% of the window stays free for actual work.
Works standalone. Gets more powerful with Asana or Linear for task sync, Perplexity for deep research, Gemini for document analysis, Figma for design files.
FonteOS is a working context for Claude Code — a structured environment, not a conversation interface. It assumes you're already in the terminal.
No vectors. No embeddings. No similarity search. Just markdown files loaded strategically through a hierarchy Claude knows how to navigate.
No server, no account, no subscription, no API key to manage. It lives in a folder on your machine. You own it entirely.
It's a file structure. Clone it and open it. No npm install, no setup.sh, no wizard. If you can read markdown, you can understand every part of it.
First run walks you through setup. Every run after that loads your world in seconds.
