After this course
After this course you can point an AI assistant at real files on your own computer and stay in control of what happens next. You install Claude Code and Codex, run them inside a practice folder that holds nothing you would mind losing, read a proposed plan before approving any of it, and check the result in the place it was supposed to land. You write prompts that carry a goal, the context, the constraints and the output shape you want, and you repair a weak answer where it stands. Your standing rules live in an AGENTS.md file and your decisions live in an Obsidian vault, so the next session starts where the last one finished.
What you will be able to do
- Run a complete Claude Code session in read only mode and prove nothing changed, by comparing file timestamps taken before and after.
- Write a prompt carrying a goal, context, constraints and a named output shape, then repair a weak answer by pointing at the exact line that is wrong.
- Give Codex a written work order, choose its sandbox and approval level, and move your standing rules into an AGENTS.md file so you stop retyping them every session.
- Install the beginner skill pack, list what actually loaded, read a skill's instructions before you trust it, and run Prompt Engineer on a fictional brief.
- Build an Obsidian vault with a Brain note and an External References note, so an agent arriving cold knows where everything is and what to read first.
- Prove a finished task in its destination using links, counts and file states, so completion becomes something a stranger could check.
Who this is for
- You run a small business and everything you have tried with AI so far has been typing into a chat box.
- You work in marketing, your team keeps saying Claude Code, and you have never opened a terminal.
- You installed an AI tool once, felt nervous about what it could reach, and quietly stopped using it.
- You want the channel courses next and would rather have the setup done properly before you start them.
Who should skip it
- You already run Claude Code daily and write your own CLAUDE.md and permission rules. Start with Agentic Engineering instead.
- You want marketing done for you. Every lesson here ends with an artifact you build yourself and save.

Questions
I have never opened a terminal. Can I really do this?
Yes, and the course is built on that assumption. Module 5 explains what Claude Code is, walks you through the official install page, then has you run pwd and ls and read the answers yourself before the assistant does anything at all. Your first session is deliberately read only, and it ends by comparing file timestamps so you can see with your own eyes that nothing moved.
What software do I need, and does it cost extra?
Obsidian is free. Claude Code and Codex are paid products billed by the companies that make them, and lesson 5.2 has you read the current official plans and prices before you install anything, so you decide with real numbers in front of you. Those subscriptions are separate from the price of this course. Modules 1 through 4 need nothing installed.
Are the AI agents included?
Five agents come free with any purchase on this site: prompt-engineer, meta-ad-creative-engine, keyword-research-agent, klaviyo-flow-builder and playwriter-browser-operator. The other 76 in the library are sold separately, or come included with the Skool community. Separately from that, lesson 7.5 gives you the beginner skill pack to download and install, and lesson 9.5 the Obsidian memory helper.
Should I buy this course alone or take the bundle?
This course is $99 on its own. The bundle is $497 for all 16 courses, which is roughly what five courses cost when bought one at a time, against $1,584 for all 16 separately. If you already know you want more than five of them, the bundle is the cheaper path.
Is there a refund?
Access is granted the moment payment completes, and these are digital goods, so a purchase is final once access has started. That is stated on the refund page, and on the 特定商取引法 page for buyers in Japan. If checkout fails or you are charged twice, write to support@murasaki.ai and we will sort it out.
How long does it take?
11 modules and 44 lessons, about 5.2 hours of video. The exercises take longer than the watching, because most lessons end with something you save in your practice folder: a session note, an access map, a verification checklist, a vault health report.
