7Brain
The shared knowledge base for the 7Mind engineering system. Published at brain.6mind.de.
What this is
7Mind Brain is a centralized wiki that gives everyone — engineers, AI agents, and new team members — a single place to understand how 7Mind’s system fits together.
Individual repositories contain the code. This wiki contains the context that code alone cannot explain: what each repo does, how repos connect, how the company positions its product, and how the infrastructure is wired.
Who reads it
Engineers use it to orient quickly when touching unfamiliar parts of the system.
AI agents (Claude Code instances running inside each repo) pull this wiki before tasks that require cross-repo context. Every repo has a CLAUDE.md that points here.
How it is organized
The wiki has two layers:
Business intelligence (business/)
Everything about the company and its product.
| Section | What it covers |
|---|---|
product/ | What 7Mind is, its markets, strategic direction |
brand/ | Visual identity, voice, and tone |
customers/ | B2C, B2B, and B2B2C segment notes |
processes/ | Internal workflows (release, oncall, etc.) |
Technical intelligence (tech/)
Everything about the engineering system.
| Section | What it covers |
|---|---|
repos/ | One note per repository — purpose, stack, deployment, integrations |
concepts/ | Architectural patterns and service configurations that span multiple repos |
packages/ | Shared NPM packages |
infrastructure/ | GCP, Cloudflare, Terraform, GitHub Actions |
integrations/ | Cross-repo data flows and connection patterns |
Where to start
- New to the product? Read product-overview.
- Touching the backend? Read elixir-backend.
- Touching the mobile app? Read 7mind-mobile-apps-monorepo.
- Touching the website? Read nuxt-website.
- Changing infrastructure? Read infra-overview first.
- Agent? Read STRUCTURE.md before doing anything else.
Seeding the business layer from Notion
Run this once to pull product, brand, customer, and process knowledge out of Notion and into the wiki. The prompt is stored at notion-onboarding-prompt.md.
Requirements: Notion MCP must be connected in your Claude Code session.
How to use it:
- Open a Claude Code session inside the brain repo with the vault at
content/. - Open
business/notion-onboarding-prompt.mdand copy everything below the second horizontal rule. - Paste it as your first message.
Claude will search Notion, fetch high-signal pages, and populate all business/ pages.
Onboarding a new repository
When a new repo joins the system, run the onboarding prompt to extract its knowledge into the wiki. The prompt is stored at repo-onboarding-prompt.md.
How to use it:
- Open a Claude Code session inside the target repository (not inside the brain repo).
- Open
tech/repo-onboarding-prompt.mdand copy everything below the second horizontal rule. - Paste it as your first message in the session.
- Claude will explore the codebase, populate the repo note, create concept pages, and commit the result.
Conventions
All conventions — naming rules, frontmatter schema, agent write protocol, commit message format — live in STRUCTURE.md. That file is the contract everyone follows.
Deployed version
This wiki is published as a static site at brain.6mind.de via Quartz and Cloudflare Pages. Every push to main triggers a rebuild.
