This one is for new parents. My latest app is now in the AppStore. Wake Wise. A Baby Sleep Tracker with suggested bedtimes. Built whilst our latest family member is asleep 😴 And @chloebulmer1705 loves it 😂 #buildinpublic https://t.co/26TEfsiIwR

If I were hiring today, I’d ask how you scale yourself with agents. By 2027, defining work, delegating it and checking the results will matter more than recalling framework trivia. Should interviews test the engineer alone or the engineer with their agents?

Fable 5.1 is incredible for maintaining design systems. I've been on teams that built and deployed design systems used across many apps. That work collectively probably took thousands of developer hours. Today I had Fable build a complete Storybook and component library with zero regressions.

Some of my agent skills were over a year old, written for models I no longer use. When models change, your skills need retesting too. I tested them with Promptfoo and Warps Skill Doctor.

One of the easiest ways to spot an AI-generated video is to just mute it. Without the audio distracting you, the unnatural mouth movements, awkward posture and strange facial expressions become obvious.

You know when you have an idea and you know it’s a good idea. I have that right now. I can feel it in my bones.

Boomers will say it’s “just summer” and that it was worse during the 1976 heatwave. But imagine a once-in-a-century heatwave like 1976 happening again, only this time on top of our much hotter summer baseline. www.bbc.co.uk/news/live/cm...

If Opus 6 releases same day as GTA6. What’s your game plan

Anytime someone mentions web components I think back to that time I tried to build a house out of twigs

I’ve been building on iOS with an App Intents-first architecture for a while. It’s not well documented and articles advocate patterns like MVVM or VIPER. With Apple’s latest Siri integrations, everything has just clicked into place. Best practices are useful, but first principles win always.

I never use plan mode with Codex. Plan mode exists in Claude because it’s over-eager and jumps straight to implementation too quickly. Codex actually takes the time to understand the codebase first and makes holistic changes based on its findings.

If you wondered… X is still full of plebs and apparently I’m a bad actor. I mean I never did drama but come on… I don’t need to be called out on it.

No AI model drop will beat evanescence releasing a song in 2026. youtu.be/ak4Ti54Y6rY?...

Claude Design is cool but GPT Image Gen 2 is even better. My workflow 1. Sign up to Mobbin 2. Use the Mobbin MCP in Codex and prompt what you’re building 3. Ask Codex to use the official GPT Image Gen skill to generate 4 UI mockups 4. Pick the best design and feed it back into Codex to build

I’ve got Codex /goal on my Raspberry Pi executed from my iPhone triaging 250 backlog items refining them to create a cohesive story on how to deliver my app from 0 to 1. It’s like having a product owner in my pocket and I’m the VP of Product 😵‍💫🤩

Agents, a Raspberry Pi, tailscale, tmux and a smartphone with a MOSH client is all you need to ship now.

I can’t imagine using AI to write code without TDD. Tests aren’t just safety nets anymore. They are the steering wheel on the race car.

Happy Pokemon day. 2026 Christmas Day will be my personal 30th Pokemon day. I remember receiving the game from my grandad and having no idea what it was and spending weeks trying to defeat Brock because I only had Charmander on my team 😂

I caught Mewtwo with a standard Pokeball as a kid. That kind of dedication has followed me into adulthood and everything I do 😏

pick 👏 the 👏 right 👏 tool 👏 for 👏 the 👏 right 👏 job. Say it together now.

The human touch will be the thing that drives downloads on the AppStore. I’ve seen a bunch of competitor apps appear recently and they all look the same. What makes your app stand out amongst the vibe coded slop will be the difference between success and failure.

Hello Opus 4.6

I’ve been using AI for things I consider myself an expert at and using time saved to level up other skills using my brain like SEO, Graphic design and marketing.

When your TV remote has too many buttons, you can’t change the channel. There’s a lesson in that.

Goodbye loyal customer 🫡

Agent Skill directories that let you install arbitrary skills and scripts, That's an attack vector waiting to be exploited surely?

MRR is a funny metric. I’ve been measuring my apps success in bills paid. My energy bill is now paid by my apps every month 😆 Next goal: the mortgage.

Claude Long Term Memory spec-kit, bmad, task-master, beads, beans. It doesn't matter which one you pick. They all do the same thing Just use one and get familiar with it - don't get stuck in that loop of switching tools every week because someone on Bluesky recommended it.

AI has turned my iPhone into a dev workstation. A user reported a bug for an app I’ve built. I shared a screenshot + high-level architecture via Codex on iOS. It found the issue, fixed it, and deployed - entirely from my phone. 12 months ago I was just doomscrolling and reading memes 😂

After watching a video Ali Abdaal created on the “GPS Method” I created a Claude skill to help me set my 2026 goals. Works a treat 👌 and here is a top tip; you can zip skills up and upload them to Claude web. github.com/mintuz/claud...

LLMs, autonomous agents, and “vibe coding” reward system thinkers. Models think locally. Slop happens when humans do too. Your value is the bigger picture and to guide them along the path.

My 2026 Indie dev goals - Reach £1000 MRR - Release a new unannounced app I’ve been building for the last month. - Start posting on TikTok behind the scenes of my indie app development process.

Have we not always been spec-driven development 🤔

My favourite 2025 app is “How We Feel” fantastic app for mental health, beautifully designed and completely free. No subscription required. A rarity in 2025 howwefeel.org/get

Web dev in 2015 was more enjoyable and easier than web dev in 2025. This my 1000th post

My christmas holiday hackathon is here 🫡 openai.com/index/develo...

Fun fact. codex has experimental skill support github.com/openai/codex...
