Agent-Native OS / The Library

Six stages. From install to running while you sleep.

Every shelf is a stage in the journey. Pick where you are right now and see what to build, what to learn, and what comes next.

56 cards across 6 stages 4D & 8D paths

Stage 01

Get oriented.

13 cards

The vocabulary and shape of agent-native work. Read these in any order before you build anything.

What Is Claude Code?

Three ways to use Claude on your computer: the CLI, the desktop app, the VS Code extension. When to pick which one.

Your Brain File: CLAUDE.md

The persistent context file your agent reads every session. What goes in it, what doesn't, and how to keep it sharp.

Slash Commands and Skills

Two ways to give your agent a workflow. Slash commands run on your call. Skills auto-trigger when Claude spots the right context.

The /personalize Flow

Twenty-one questions about you, your work, and how you learn. Claude turns the answers into a CLAUDE.md tailored to you.

The Modes Claude Can Run In

Five modes for how much your agent does without asking, from asking before every action to running with no prompts. The autonomy ladder you climb as trust grows, and the two you have to turn on first.

Running Claude Safely

Permissions, backups, and the safety net. Stop worrying about accidentally deleting things. Set up the layers that make trust possible.

Secrets Management

Why your agent's API keys belong in a vault, not a chat or config file. The three paths (Infisical, 1Password, a locked .env) and why Infisical is the fast, safe default. The why before the build.

Upgrade to 8D Secrets

Make your vault live. Install the Infisical Agent and a machine identity so your agent can read vaulted keys headlessly, for scripts, MCPs, and scheduled jobs.

Stage 02

Connect your tools.

10 setup steps

Give your agent its senses. Install your first MCP, borrow a working CLI, and stand up a basic second brain. Everything in the next stage builds on these.

🔌
4DSetup

Install Your First MCP

Firecrawl as the cleanest useful first install: one free API key, no OAuth dance, no Google Cloud project. One command and you can verify the doors actually open before you move to Gmail or Calendar.

Borrow a Working CLI

Pre-built CLI tools you can install today: Slack, Zoom, Google Workspace, N8N, Firecrawl, MacWhisper. Inherit the plumbing, write your own skills on top.

Know When to Build a CLI

Some services already have great MCPs. Others need a custom CLI. This is the decision tree: when to build, when to use what's shipped.

The Cairns Three Tiers

One skill that takes anything you throw at it (links, voice memos, screenshots) and files it where it belongs. Raw preserved, card generated.

Stage 03

Ship your first agent.

7 small builds

Pick one. Small builds you can stand up in an afternoon, each wired to the tools and memory you just connected. Every one teaches a piece of the capstone.

Stage 04

Go deeper.

13 frameworks and builds

The advanced layer: sub-agent teams, custom CLI architecture, and a second brain that grows into real semantic and graph search.

🪄
4DFramework

Sub-Agents, Background Agents, and Agent Teams (Oh My!)

One agent isn't always enough. Three primitives plus four named patterns from Hunter's merge-2-main library. Six agents running from a single prompt becomes the new normal.

Build Your First CLI

Four phases: scrape the API docs, build the tool, write per-method skills, cache the full spec for everything else. The Slack CLI walkthrough ships 306 methods this way.
