Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by garrytan on GitHub. Read the source before you install it.

Installation

Install the Repo Architecture AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/garrytan/gbrain.git /tmp/gbrain
mkdir -p .claude/skills
cp -r /tmp/gbrain/plugin-variants/gbrain-coding/skills/repo-architecture .claude/skills/repo-architecture

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Repo Architecture in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Repo Architecture on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Repo Architecture is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Repo Architecture — Filing Rules

Full filing rules: See skills/_brain-filing-rules.md

Contract

This skill guarantees:

Every new page is filed by primary subject (not format, not source)
The decision protocol is followed for ambiguous cases
Common misfiling patterns are caught

Phases

Identify the primary subject. What would you search for to find this page?
Walk the decision tree:
- About a person → people/{name-slug}.md
- About a company → companies/{name-slug}.md
- A reusable concept/framework → concepts/{slug}.md
- An original idea → originals/{slug}.md
- A meeting → meetings/{slug}.md
- Media content → media/{type}/{slug}.md
- Raw data import → sources/{slug}.md
Cross-link. Link from related directories.
Check notability. See skills/conventions/quality.md notability gate.

Output Format

Advisory: "File this at {type}/{slug}.md because the primary subject is {reason}."

Anti-Patterns

Filing by format ("it's a PDF so it goes in sources/")
Filing by source ("it came from email so it goes in sources/")
Creating pages without checking if one already exists
Using sources/ for anything except raw data dumps

Frequently asked questions

What does the Repo Architecture AI skill do?

Where new brain files go. Decision protocol for filing brain pages by primary subject, not by format or source. Reference for all brain-writing skills.

Why use Repo Architecture on TypingMind?

Because you install it once and use it with any model. Repo Architecture is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Repo Architecture in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/garrytan/gbrain/tree/master/plugin-variants/gbrain-coding/skills/repo-architecture. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Repo Architecture?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Repo Architecture?

As many as you like. As long as a model supports skills, you can use Repo Architecture with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Repo Architecture AI skill free?

Yes. It is published on GitHub by garrytan under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
