What it does
3D Brain is an agent skill from nateherkai/AIS-OS. Use when someone asks to build a 3D brain, visualize their AIOS or second brain, turn their knowledge into an interactive graph, or run /3d-brain or /3D brain.
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 30 other files, including scripts, reference files and assets (for example `README.md`, `agents/openai.yaml` and `assets/template/README.md`).
It sits in Knowledge Management, covering Second brain. The repository describes itself as: AI Operating System starter kit for Claude Code and Codex. Five skills: /onboard, /audit, /link, /level-up, and /3d-brain. Includes the Three Ms framework.
When your agent uses it
- Someone asks to build a 3D brain
- Visualize their AIOS
- Turn their knowledge into an interactive graph
Example prompts
- “/3d-brain”
Requirements
- Node.js
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Find the AIOS and the package
- Ask for the name and categories
- Scaffold the exact experience
- Preserve behavior and honest connections
- Verify and deliver
What it can do on your machine
Read from SKILL.md and the folder at commit ce9cb93. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (JavaScript, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
npmnode
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
3D Brain loads about 2.1k tokens when it runs, and up to ~4.9k if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 1,191 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,191 words (~2,139 tokens).
“Turn the user's actual AIOS files into a personalized, local 3D knowledge globe. Use the bundled working application, not a new interpretation of its appearance. Preserve its spherical composition, colored categories, central orb, restrained connection particles, Cinema mode, and interactive…”
