Now
you can work on your own

Free on the Mac App Store.
A MacBook normally sleeps when closed, and then cannot be reached remotely.
A small utility that keeps it awake even with the lid closed.

Terminal → move to the working folder → enter claude remote
→ The session appears as a chat in the Mac app. Continue giving instructions there.

Benefit: easy to continue the same session on mobile; terminal, Mac app and phone form one workflow.
⚠ I have not tried Cursor remote. Paid remote tools were slow, so I use them only in emergencies.

Shared across iPad, Mac and iPhone. Like KakaoTalk.

My use: simple questions, writing fiction with Projects, and researching personal-website examples.

In your code folder (or the parent folder containing web/server projects), set up remote access → it appears in the Claude iPad/iPhone app.

Queue up small instructions and check progress during drives or tea breaks.

Not a direct connection to Cowork itself: go to the folder Cowork is working in, set up remote access, then it appears in the iPad/iPhone app for small instructions.

My use: presentation drafts and technical reviews of lecture content and slides.

— Session 1

“When you wake up, step out of the shower, or return from coffee, has something been made?
A report, a spreadsheet summary, something organized? Probably not.”

— Mitchell Hashimoto · 2026.2.5 · My AI Adoption Journey

“Whenever an agent makes a mistake, design a mechanism that prevents the same mistake from happening again.”

The creator of Terraform and Vagrant. Officially adopted by OpenAI within 2 weeks; Anthropic and Martin Fowler followed with publications.

The core equation

Agent = Model + Harness

If the model (Claude/GPT) is the brain, the harness is the environment that makes it work properly: ① constraints against going off task, ② limiting it to the few tools it should use, ③ specifying what it must and must not do.
AGENTS.md, tool connections, automated tests and error-recovery loops: a vast set.

My own work in progress

I am refining harness and agent concepts in my Grimoire project. The central effect: instead of the developer fixing Claude’s mistakes directly, Claude checks and critiques its own code and documents.

Developers already apply parts of this, knowingly or not. How many have built it systematically enough for Hashimoto or Martin Fowler to say “You are really doing it properly” is unclear. Knowing these two terms and their roadmaps is what enables a work environment where humans do little and AI works precisely.

Recognize the limits

Even with dozens of documents and a well-established canonical source, a moment comes when Claude turns stupid.

Remember the developer-chat screenshot from session 3: “Claude has gone crazy. Where did the old one go?”

Harnesses and agents, in plain language

Instead of me telling Claude “Do it again”,
Claude checks, corrects and retries its own work.

A loop where AI checks and corrects its output without a human stepping in every time. That is the essence of Hashimoto’s “mechanism that prevents the same mistake twice.”

My route

Before dawn, leave on the motorcycle with iPad and iPhone
→ Reach Onam Lake Park in Namyangju and stare at the lake
→ Review Claude’s report on my phone and plan the next instructions
→ Ride alone to the Seoul Museum of Craft Art in Anguk
→ Catch my breath under the night sky → give Claude more work.

The workflow in one line

Terminal → working folder → claude remote → a chat appears in Mac/mobile apps → continue instructions there.

What they are doing

Remotely restoring a classic fighting game from 20 years ago.
Uses all tokens on Claude’s top plan. Company work stays in a separate company Claude account.
Checks the Mac mini and Windows PC only after work; during weekdays, monitors remote tasks in progress.

Now

Moved from business support at a spatial-design firm to head of an AX team.
AX means AI Transformation: AI strategy departments Korean large and midsize companies began creating in 2024–2026, following digital transformation (DX).

A friend, in week 3 of vibe coding

He cannot distinguish Claude-generated HTML from a web developer’s web project. Two hours of tutoring did not clarify canonical sources and references. He even raised technically impossible objections about iOS push notifications.

But he is automating his own job. He is building a webpage that calculates and organizes overseas-goods quotes for an exporter, work previously done by several field staff and team leads measuring dimensions and accounting for damage.

Where he gives instructions: cafés, bars, anywhere — iPhone/iPad + Amphetamine + remote.

① CRUD practice: try different things

CRUD = Create, Read, Update, Delete, the backbone of nearly every web service.
Try building small things: a guestbook, simple reservations, a site for your designs or photos.

② Vercel/Supabase self-check

“Can my entire service be built with Vercel and Supabase?”
If not: “What should I use for the server: Azure, AWS or GCP?”

③ Compare hosting and servers (good for CLI work)

“Among Cloudflare and Korean hosting providers, which can you work with best through CLI?”
“How do I connect my webpage to proper hosting and a server? Separate what I must do myself from what you can do through CLI.”

⚠ Key point when working on servers, infrastructure and hosting

If you click through AWS/Azure page by page, asking “What is this?” for every term, you will burn out.

Ask Claude about unfamiliar words, and tell it to perform the actual configuration and work through CLI. That is the way.

① Ask about the vocabulary

“What does native development mean?”
“What does web hybrid mean?”
“Why use Flutter? How does it differ from web hybrid and native?”

② App-release process

“How do I create iOS/Android accounts and release an app?”
Have Claude guide each step: Apple Developer/Google Play Console signup, review and app submission.

⚠ Note: initial iOS/Android release setup is difficult

This is an area where outsourcing/turnkey vendors give online-shop owners guides longer than 10 pages.

If the owner cannot understand the guide, the vendor does it for them for a service fee. The process is that complex; Claude’s step-by-step guidance has real value.
