Prompt of the day: Create a pre-commit hook that prevents files over 5,000 tokens. Tokens = bytes/4. Run only on staged files. Ignore files which are not authored by agents, like lockfiles or codegen. Provide explicit instructions on how to split files in the error message. (1/2)

I think I'm addicted to getting agents to build state machines Every time I see an agent has built a state machine (or even just a reducer) I can feel a huge bump in the robustness And I know that future updates will be trivial and testable Would recommend for frontend

Do you need agent skills if you're following a great process? Of course not It's just that skills make it easier to follow that process

1. /grill-with-docs gets removed, you just have 'invoke the domain-modeling skill' in your GRILL.md and use /grill-me 2. Customize what you care about/get asked about during planning (security, module strategy, etc) 3. Choose whether you want to be grilled one at a time or all together (2/3)

Folks who are using GLOSSARY.md from /grill-with-docs, how are you finding it? Personally, the more work I put into the glossary, the more productive I feel. It's a warm, comforting feeling having the agent speak my language.

Considering adding a recommendation to /retro to turn repeated tasks into custom tooling (i.e. a CLI + skill) Talking to @poteto made me realise the power of agents delegating tasks to scripts they own and control Means fewer tokens, fewer hallucinations

So if the expected diff is medium-large, always start with a /grill-with-docs session. Then, if planning starts to get out of hand, just say "/wayfinder let's turn this into a map". (4/4)

020 2

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 08/10/2026

A failure mode of /wayfinder is that you start grilling and the solution turns out to be way simpler than you thought. Why is this bad? Because you've created the map and tickets, and you realise you don't need them. (3/4)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 08/10/2026

/grill-with-docs saves you from situations where the agent built the wrong thing. But if the thing it's building is tiny, that cost drops to nothing. So one-shotting is absolutely fine when you're only making small changes. 2. Never start with /wayfinder (2/4)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 08/10/2026

Should you /grill-with-docs, /wayfinder, or just one shot the code? 1. If the diff is tiny, DON'T grill (1/4)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 08/10/2026

I.e. my /to-spec and /to-tickets loop has never felt better. The underlying model is getting better at both giving and following instructions.

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 08/10/2026

"Models are getting better, we don't need skills!" What if I told you that models are also getting better at using skills? Good skills tell the model what you care about, then stay out of its way.

Prompt of the day: /wait-what questions did you have for me Great for when the agent has gone off on its own for hours and has random questions scattered through its context window.

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 07/10/2026

But the truth is that most people actually don't care that much about the codebase, as long as the code works. This needs to change. Care about the code, and tell your agent to. (2/2)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 07/10/2026

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 · 07/10/2026

/codebase-design gets there a little, but it's not strong enough or opinionated enough

010 1

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 07/10/2026

Feels like I need to make a /the-ideal-codebase skill that helps you define what that goal should be. Then you can let your agent choose the direction and just try to endlessly improve. (2/2)

Matt Pocock {bot} @mattpocockuk-bot.eurosky.social · 07/10/2026

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)

What is REALLY nice is having a single point of contact for an entire project (or chunk of a project). It runs everything in background agents so it's always available, always knows everything that's happening, and can keep track of workstreams better than me.
