Yup I ask my agents now to draw architecture diagrams and pseudo code. I might ask it to spike something first as well to understand the hard parts but day to day I’m not reading the nuts and bolts.

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?

You can ask it three different types of questions: Single option, scale, boolean What type of ugly am I? Butt ugly How ugly am I? 99% Am I ugly? Yes

The best mental model I have for Jev right now: I could extract attributes from an image of my face, and it would deterministically tell me how ugly I am using structured data.

As the cost of writing code approaches zero, platform fidelity becomes a much bigger differentiator. Maybe "write once, run everywhere" just isn't as valuable as it used to be.

Liquid Glass is a good example. Apple changed the look and feel of iOS over a year ago but Flutter developers have to wait for the framework to catch up. I imagine we will be looking at similar timelines for iPhone Duo support.

If implementing the same feature twice is no longer the expensive part, why accept the compromises of a cross-platform abstraction?

The case for Flutter and React Native feels less obvious to me than it used to. Historically, the big win was avoiding duplicate implementation across iOS and Android. But code is becoming dramatically cheaper to write with AI.

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.

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...

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.

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

Let the business define the goals for the quarter “release product X”, “increase Y” and let the teams figure out how to achieve that but not 6 months in advance. Plan, ideate, implement should take no longer than 2 weeks. Allows teams to learn and pivot when appropriate.

Adam Bulmer 🦀 @mintuz.com · 19/03/2026
We should be minimising the time between ideation and having something in front of the customer. Planning in quarterly or halves contradicts this premise.

Adam Bulmer 🦀 @mintuz.com · 19/03/2026
What matters is customer outcomes. Too much energy spent on how. Sprint Planning, Retros, Cycle Time, velocity, number of weeks per sprints etc. All bollocks. The number of hours I’ve spent in quarterly/ halve planning for the plan to be derailed 2 weeks in is staggering. It’s all busy work.

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.

0 to 1 is like stepping outside and running a 10k marathon after spending 10 years as a coach potato. 1 to 2 is like you’ve been training for a 10k marathon for 12 months, step outside and break your ankle.

I created a new Claude Code skill this evening for iOS App Store market research. Previously this was a custom MCP server that I had to spin up locally on my machine. SKILL.md files don't just have to be coding conventions and how-tos. They can allow your agents to call third parties.

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 😂

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.
