question 1 of 2
where are you right now?
be honest — there's no wrong answer. this decides what we show you.
beginner
just starting out
never opened a terminal, or just heard about Claude Code. starting from zero.
maker
i know some basics
used Claude in the browser. comfortable with tools. not a developer.
developer
i'm a developer
comfortable in the terminal. want the advanced setup. show me everything.
question 2 of 2
have you installed
Claude Code?
Claude Code is the CLI — you run it from a terminal instead of a browser tab.
new here
not yet
show me how to install it step by step. i'll walk you through everything.
installed
yes — it's running
i have it installed. help me write my CLAUDE.md and connect my tools.
power user
installed + CLAUDE.md done
already set up. show me the next level — plugin, MCPs, hooks, skills.
step 1 of 4 · getting ready
you'll need 3 things first
none of these cost anything to start — and we'll link you to each one.
1
a modern terminal — download Warp (free, recommended)Warp is a terminal built for humans. better than the default Terminal app — it has autocomplete, AI suggestions, and works out of the box.
⚡ download Warp at warp.dev
⚡ download Warp at warp.dev
already have a terminal you like? keep using it. this step is optional.
2
Node.js (version 18 or higher)Claude Code runs on Node.js. Check if you have it by opening your terminal and typing:See
See "command not found"? → download Node.js (LTS) here
terminal
node --version
v18 or higher? ✓ you're good.See "command not found"? → download Node.js (LTS) here
3
a Claude Pro account ($20/mo)Claude Code requires Claude Pro or an API key. upgrade here if you're on the free plan.
step 2 of 4 · installing
install Claude Code
open your terminal and run this one command:
terminal
npm install -g @anthropic-ai/claude-code
then open your project folder and start it:
terminal
cd ~/Documents/my-project
claude
▸ running into an error?
command not found: npm▾
Node.js isn't installed.Download it here (LTS version) → install → restart terminal → try again.
EACCES: permission denied▾
npm doesn't have write access. add sudo:Type your Mac password when asked (nothing shows — that's normal).
terminal
sudo npm install -g @anthropic-ai/claude-code
command not found: claude▾
Install succeeded but terminal can't find it yet.Close and reopen your terminal, then try
claude again.login fails / browser won't open▾
Use API key login instead:Get your key at console.anthropic.com then run:
terminal
export ANTHROPIC_API_KEY=sk-ant-your-key

💬still stuck? message me on LinkedIn — show me the error and i'll help you get unstuck.
step 3 of 4 · your second brain
set up your folder structure
this is what lets claude navigate your business without being told where to look.
option A · manual setup
create the PARA structure yourself
folder structure
second-brain/
├── 00_Inbox/
├── 01_Projects/
│ └── Clients/Active/
├── 02_Areas/
├── 03_Resources/
└── CLAUDE.md ← create this next
⚡ option B · arscontexta plugin
github ↗the second brain plugin
instead of copying a template, it interviews you for 20 minutes and generates a knowledge system tailored to how your brain works. no template — your exact cognitive architecture.
claude code terminal
/plugin marketplace add agenticnotetaking/arscontexta
/plugin install arscontexta@agenticnotetaking
/arscontexta:setup
requires tree + ripgrep — install with: brew install tree ripgrep
step 4 of 4 · the key file
write your CLAUDE.md
paste this into Claude Code. it will ask you 8 questions, then generate your complete setup.
paste into claude code
you are setting up my CLAUDE.md — the file that makes you understand my business permanently.
// founder interview. one group at a time. wait for answers.
GROUP 1 — your world
1. what does your company do? (2-3 sentences)
2. your role, and how many people on the team?
3. current clients or customers?
→ wait. then group 2.
GROUP 2 — your tools and pain
4. tools you open every single day?
5. tasks that repeat and feel like a waste of time?
6. biggest focus this month — the ONE thing?
→ wait. then group 3.
GROUP 3 — your rules
7. what should you NEVER do without asking me first?
8. existing folder structure, or starting fresh?
→ generate all 3 outputs after all answers.
OUTPUT 1 — CLAUDE.md
include: who i am | clients | tools | focus | tasks to automate
must include:
- how to navigate: explore folders freely. find client folders when asked. if a skill exists, use it.
- how to work with me: ONE clarifying question when unclear. confirm before irreversible actions. flag anything risky.
- my rules
OUTPUT 2 — folder structure
00_Inbox/ 01_Projects/Clients/Active/ 02_Areas/ 03_Resources/ CLAUDE.md
OUTPUT 3 — first 3 MCPs
based on their tools. one line each: tool → what it unlocks.
you're all set 🎉
the foundation is live.
here's what comes next.

bonus — community skills list
i like this list of community skills — good inspiration for what to build first. i'll drop mine in a few days. follow the series to get it.
github.com/sickn33/antigravity-awesome-skills ↗power move · the second brain plugin
github.com/agenticnotetaking/arscontexta ↗arscontexta — your personal knowledge system
this Claude Code plugin doesn't use a template. it interviews you and derives a knowledge architecture from how your brain actually works.

derives, not templates
every decision traces back to cognitive science research

prerequisites: brew install tree ripgrep · requires Claude Code v1.0.33+
next layer · connect everything
MCPs — claude connects to anything
MCP = Model Context Protocol. one connection = claude can read, write, and act inside that tool — no copy-paste, no tab switching. start with 2. grow from there.
🏪 smithery.ai — the MCP marketplace
browse 2,000+ MCPs in one place
search by tool name, copy the install command, done. the easiest way to discover what exists.
smithery.ai ↗
🔍 how to find any MCP
can't find it? just search:
"tool name" + mcp github
or go to smithery.ai and search the tool name. if a community built it, it'll be there. over 2,000 MCPs exist as of early 2026.
start with these 2
Notion
read/write any page, create databases, import docs — without opening the browser
smithery ↗
Slack
digest any channel, draft replies, summarize a week of conversations. your inbox becomes searchable.
smithery ↗
📋 productivity & docs
📱 social & outreach
🔧 dev & engineering
💳 finance & commerce
🤖 AI & research
⚡ automation
🎨 design & media
🔌 core / built-in
... and 2,000+ more at smithery.ai. if a tool exists, someone probably built an MCP for it.

final layer · safety net
hooks — invisible guardrails
shell scripts that run automatically before/after claude takes any action. you don't think about them. they just work.
PreToolUse
runs before claude acts. can inspect, block, or modify the action.
PostToolUse
runs after claude acts. can log, notify, or trigger something else.
bash-safety.sh
PreToolUse · Bash
blocks forever:
git commit, force push, reset --hard, rm -rffile-protection.sh
PreToolUse · Edit
blocks edits to
.env and credentials. warns before touching CLAUDE.md.file-backup.sh
PreToolUse · Edit
auto-backups every file before editing. keeps last 10 versions. undo anything.
file-logger.sh
PostToolUse · Write
logs every file change to a daily audit log. see exactly what claude touched.
stop-notify.sh
Stop event
plays a sound + macOS notification when claude finishes. walk away, come back when done.
📦full hooks bundle ships as a free GitHub drop on day 5. comment HOOKS on that post to get the link.
