I Turned Claude Opus 4.8 Into My Entire AI Operating System

Summary

Nate Herk walks through his “Herk 2” AI Operating System built around Claude Code + Opus 4.8. The key insight: context is king, not the model. Everyone has access to the same models — the moat is your knowledge architecture.

The Default Shift

Reach for Claude Code first before Chrome or any other app. If the use case is brainstorming, writing, thinking — not just coding — use Claude Code anyway. This builds up your context continuously and eliminates context switching.

“AI isn’t king. Opus 4.8 benchmarks — who cares? Everyone has access to the same models. If the AI is king, wouldn’t everybody be king? Context is king.

The Four C’s Framework

LayerWhat it means
ContextDoes it know your business? Open a fresh session → it should be able to describe what you do, who works there
ConnectionsWhat can it actually touch? Calendar, tasks, Slack, email, QuickBooks, CRM — via APIs / MCP servers
CapabilitiesHow does it do work? Skills = instruction files (writing guides, frameworks, SOPs)
CadenceThings that happen while laptop is closed — scheduled automations

Each layer depends on the previous one.

The Three M’s (Mindset)

  1. Mindset — Shift to “do everything through the AIOS”
  2. Method — The 4 C’s architecture
  3. Machine — The tools (Claude Code, Codex, etc.)

Building Skills

Two approaches:

  1. Build forward — Tell Claude Code “I want a skill for X” and iterate (~50 tries sometimes)
  2. Reverse engineer — Complete a task end-to-end, then have Claude Code look back at the conversation and extract the skill from what worked

Skills can be dead simple — even just a saved prompt you type repeatedly. Example: session handoff skill (summarize context, open decisions, key files — so you can clear context and pick up fresh).

The Bike Method (Trust Building)

Don’t hand the keys over immediately. Like teaching a kid to ride a bike:

  1. Walk with them, hold the handles
  2. Training wheels
  3. Let them ride down the street while you watch
  4. Eventually full autonomy

Each iteration builds trust. Instructions ≠ capabilities — if an email-sending tool is connected, the agent can use it even if you said “don’t.”

Real cautionary tale: An AI agent on his team proactively picked up a task and sent 3 promotional emails to 150K+ inboxes that weren’t supposed to go out. Permission layers matter.

Organization

  • Everything is files and folders — tool agnostic (works with Claude Code, Codex, OpenClaude)
  • agents/, skills/, other-worlds/ (separate Claude Code projects)
  • CLAUDE.md changes almost daily — don’t stress about getting it perfect
  • Quarterly reprioritization = folder restructuring is normal

No Dashboard Needed

Nate doesn’t use a visual dashboard (Obsidian knowledge graph etc.). He works directly in the terminal. Productivity isn’t hours worked — it’s “did I move the needle closer to my goal.”
