An interactive setup wizard for creating a personal workspace, including folders for notes and a generated instruction file.

In plain words
What is it for?
Use it to start a personal knowledge system and create its basic folder structure, provided the destination is not already set up.
Why use it?
It guides initial setup by collecting your name, technology stack, goals, recurring problems, and preferred storage location.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is Railly/agent-brain's own configuration. It tells Claude Code and Codex how to work on agent-brain itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-brain configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

init scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Interactive setup wizard for your personal OS. Asks questions, builds your vault, generates your CLAUDE.md.

WAVE 0: Welcome

Print:

Welcome to your Personal OS.

I'll ask you a few questions to set everything up.
This takes about 2 minutes.

WAVE 1: Questions

Ask these directly, one at a time. Wait for each answer before asking the next.

  1. "What's your name and what do you do? (e.g. 'Sarah, frontend engineer at Stripe')"
  2. "What's your main stack? (e.g. 'TypeScript, React, Next.js, Tailwind, PostgreSQL')"
  3. "What are your top 3 goals right now? (career, learning, personal, anything)"
  4. "What's one recurring failure you keep repeating? Be honest, nobody reads this except your AI. (e.g. 'I start side projects and never finish them')"
  5. "Where should I create your vault? (default: ~/brain)"

Store all answers for WAVE 2.

WAVE 2: Create vault structure

Use the path from question 5 (default ~/brain).

Before writing, check whether the destination already contains CLAUDE.md, AGENTS.md, or 01_Inbox/. If it does, stop without changing it and direct the user to docs/MIGRATION-v2.md.

mkdir -p "{path}/01_Inbox/processed"
mkdir -p "{path}/02_Journal/daily"
mkdir -p "{path}/02_Journal/weekly"
mkdir -p "{path}/02_Journal/reflections"
mkdir -p "{path}/03_Garden/_MOCs"
mkdir -p "{path}/03_Garden/concepts"
mkdir -p "{path}/03_Garden/people"
mkdir -p "{path}/03_Garden/tools"
mkdir -p "{path}/03_Garden/meetings"
mkdir -p "{path}/04_Projects"
mkdir -p "{path}/05_Areas/content-creation/ideas"
mkdir -p "{path}/05_Areas/health/daily"
mkdir -p "{path}/06_Content"
mkdir -p "{path}/07_System/context-files"

WAVE 3: Install workflows

Copy the canonical skills and Claude Code adapters:

cp -R .agents "{path}/.agents"
cp -R .claude "{path}/.claude"

Keep /init installed so the user can inspect the setup contract later. Do not run it against the initialized vault again.

WAVE 4: Generate CLAUDE.md + AGENTS.md

Create {path}/CLAUDE.md using the answers from WAVE 1. Then copy it to {path}/AGENTS.md so Codex and other agents read the same context. Follow this structure:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
