I've worked with Vojta for four years He builds most of the code for my course sites, including: aihero.dev totaltypescript.com aicodingdictionary.com He knows a thing or two about frontend design And guess what, his skills are 🔥 (1/2)

Today's hot take: Agents are actually really good at strategic programming It's just they aren't RL'd to actually care about it "Just do the task at hand, don't do anything else" So all you need to do is to tell your agent to care about its own codebase. (1/2)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 12h

Starting to realise that to make agents strategic, they really just need a clear goal. I.e. they can hill climb anything (as long as they have the data), but they need to know where they're going. (1/2)

1. Oh shit, AI can do my job better than me 2. Software engineering is dead! 3. I can vibe code as much slop as I want! 4. Oh, things are not going well. Fable/Sol/Opus all suuuck 5. But what if I constrain the agent? Put it in a straitjacket? 6. Oh, the results are pretty good now. (1/2)

Prompt of the day: /writing-for-agents my AGENTS.md is a hot mess, propose a series of restructurings that: - Remove no-ops - Use progressive disclosure - Move instructions to CODING_STANDARDS.md Apply your work over three subagents, each more radical than the last. Create a single PR. (1/2)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 06/10/2026

IMO you should be specializing my skills to your work I.e. you should extend /grill-me to make sure it: 1. Holds you to a high standard of product design 2. Does a survey about security implications 3. Uses /show-me to preview the code for you

Thanks for 400K on YouTube pals 👌 Got recognised at my kids' local park the other day, things are getting mad

Having shipped the AI Coding Crash Course (largely for beginners/intermediates) means that the upcoming Cohort will be really quite advanced/in-depth Just recorded an 11-minute /grill-with-docs session about DDD, scenario testing, and sharpening language. It's so good

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 05/10/2026

Prompt of the day: /retro take a look at as many GitHub PR review comments as you have access to from my team. Create suggestions for updates to CODING_STANDARDS.md (breaking into multiple files as needed). Makes your PR comments inform the code going forward.

Oh shit I just realised that grilling is where the meat and the metal interact

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 05/10/2026

I've added /retro into the "Main Flow" of my skills - I consider it that important. Even running it on a 'successful' agent session can turn up inefficiencies and workarounds the agent is battling against. www.aihero.dev/skills-retro

Prompt of the day: 1. Re-check mattpocock/skills for the v1.3 release. Rename CONTEXT.md to GLOSSARY.md. Check /setup-matt-pocock-skills for any required changes. Perform a diff of the skills in my repository vs Matt's. (1/2)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 04/10/2026

By popular demand, I'm shipping v1.3 of my skills today. Too much hype behind /retro not to ship it. Enjoy going back through your old transcripts and figuring out improvements. Docs, video, and announcement post coming Monday. github.com/mattpocock/skills/releas…

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 03/10/2026

My hot take from chatting to @poteto is that we should use MORE abstractions in the AI age You can use them (combined with harsh lint rules) to reduce the design space available to the agent and constrain them only to good decisions. (1/3)

Prompt of the day - useful, or annoying?

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 02/10/2026

It's filming day for the new course. The ginger beard has reached a critical juncture. Do I keep it for my November cohort? I am genuinely ambivalent. It's itchy. Poll below.

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 02/10/2026

Prompt of the day: /retro read my last 10 coding agent sessions and find ways to make my repo easier to navigate. Find where agents take too long to find relevant information, or rely on out-of-date docs. Improving navigability is such an underrated way to save tokens.

GitHub actions are a super easy way to get started with software factories (1/3)

A: an agent with access to a debuggable/clickable dev server B: one without I'd argue that the difference between A and B is bigger than most models Fix the environment your agent runs in

Is anyone doing CRAP scoring in TypeScript with Vitest? Is it possible? What are you using?

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 01/10/2026

Started doing this. Very useful for when you're dictating out a bunch of stuff and you can only half-remember what you've said. I prefer a 5-word version: Restate my intent before continuing

Me, 2020: ugh this code sucks, let me fix it while I'm here Claude, 2026: let me copy the prior art in the repo so the codebase stays consistent

mattpocock/skills prompt of the day: /codebase-design Take a look in the repo for shallow modules, applying the deletion test and look for candidates for deletion. Helps kill unnecessary abstractions.

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 01/10/2026

Effect feels insanely good to use with agents: - Typed errors/dependencies power up your type checking - DI makes designing good codebases easy - Built-ins for EVERYTHING, no agent creativity required An outrageous advantage for any non-frontend TS code

Super excited to be interviewing @poteto, live, in ~48 hours on YouTube. We'll be nerding out about skills, high-velocity software factories, and learning SOTA techniques for shipping with agents. This Friday - 9AM PT. Don't miss it! youtube.com/live/MN9dGgmLyso

Opus 5.5 has been building animatics for me - draft versions of videos I'm about to film. It walks through the actual lessons, creates stills of what it thinks the learner should see, and narrates them with TTS. (1/2)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 29/09/2026

My top 3 skill makers: - @poteto - @dexhorthy - @emilkowalski Always learn a ton from reading their skills.

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 26/09/2026

Trying something new in my course creation process Animatics - AI-generated stills + speech (via TTS) that help me see what a video would look like once filmed I also get the agent to walk through the exercise as I would when I film it. (1/2)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 26/09/2026

This is really smart. There are definitely a set of rules that are too complex to lint deterministically that feel wasted on full-scale intelligence. - Using useEffect in sensible ways - Keeping good comments while killing bad ones QT: twitter.com/i/status/21038316535755…

Tons of folks ask me "how do I create a CODING_STANDARDS.md file?" My answer is that if you're using it right, it should only be empty for about 5 minutes. Every meaningful thing your agent gets wrong should be noted into CODING_STANDARDS. (1/2)

Watched a @poteto video this morning Shipped more work than I have done in weeks Sometimes correlation is causation

020

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 25/09/2026

Thinking about making a skill called /fix-one-thing: "Read CODING_STANDARDS.md. Find a violation in the codebase, and fix it. Make the PR small and easy to review, with a small blast radius." Run it whenever you've got a spare moment, or once an hour on a schedule.

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 25/09/2026

Here's the talk I gave at AI Engineer Paris: I announce /retro and /pr, and talk about how to get more PR's through your org faster by: - Stopping the slop - Making PR's easier to review (with /pr) www.youtube.com/watch?v=g0vqT_wZtXA…

Opus 5.5 generated this with a single prompt ⬇️

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 23/09/2026

This is mostly correct, but it assumes that 'unit' means 'the smallest possible unit' Testing larger units has ALWAYS been a good practice - it makes your tests less sensitive to structural changes So not "dead in the water", just software fundamentals coming back around (1/2)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 22/09/2026

I hear this a LOT from panic-stricken devs: "I've inherited a vibe-coded codebase, how do I save it?" Either from devs who have stopped caring, or non-technical folks trying to push AI beyond their abilities. A huge chunk of my next course will tackle this: (1/2)
