Feels like you could start being productive in Effect | TypeScript at Scale with only 10-15 functions, but I have no idea yet which of the 500 or so of them I should choose. Still, my investigations continue.

I was today years old when I learned you can do CMD-SHIFT-L to select all occurrences of a piece of text in VSCode. How many hours have I wasted repeatedly hitting CMD-D 😬

gql.tada is just nuts. Instant type inference from graphql strings. It's like tRPC for GraphQL.

Cursor shipped a /thermo-nuclear-code-review for the TOUGHEST AI code review possible. But is it any good? Let's dive in:

/grill-me is my most popular skill ever. I get 5-10 messages a day about how it’s changed people’s workflows for the better But… I’ve stopped using it for code. Here’s the improved version:

Anthropic has given us a "dedicated monthly credit" Which, in effect, slashes AFK usage limits of Claude Code by ~5-20X Here's how it affects you:

I built my own software factory, and I open-sourced it. It's called Sandcastle. Here's how to use it:

Things people get wrong with my grill-* skills: - Being too passive - Not grilling in parallel - Not prototyping - Going into the dumb zone - Grilling too hard - Grilling too large a topic - Using too dumb a model - Clearing the context too soon Here's the breakdown:

You asked for it, so here it is: a deep-dive on my new /handoff skill. It's an alternative to /compact that gives you WAY more flexibility with your context window. - Think of an idea, handoff to another agent to implement - Grill, handoff to prototype, handoff BACK Enjoy:

Two new skills this week! - /handoff compacts your current session to a markdown file - /prototype helps you prototype anything - UI or backend And a bunch more updates. Here's the changelog:

For weeks, folks have been asking me to make a video building a feature with Claude Code in a real codebase So here you go: - From idea to AFK agent to QA - Every single step explained - No slop allowed

My Ralph Wiggum breakdown went viral. It's a keep-it-simple-stupid approach to AI coding that lets you ship while you sleep. So here's a full explanation, example code, and demo.

Here's my AI coding workflow and all the skills I'm using: Idea -&gt; /write-a-prd -&gt; PRD PRD -&gt; /prd-to-issues -&gt; Kanban Board Kanban -&gt; ralph​.sh -&gt; Ralph Loop Ralph Loop -&gt; Manual QA Links below to skills

My 'grill-me' skill went viral. mattpocock/skills is up to 9K stars. Quote tweets of it are doing numbers. It's the most useful skill I've written, and I use it even outside of coding:

Never run claude /init It'll burn tokens, go out of date in days, and bloat your system prompt. Here's why:

AI helps you move faster, but it just accelerates software entropy. Here's how to de-slop a codebase ruined by AI, with one skill:

As soon as your software gets any users, you'll need to deal with every veteran developer's nemesis: ...the backlog Here's a skill I made (/triage) for burning through your backlog at record speed:

claude --worktree is so good I'm making it my new default. Don't know why you should care? Couldn't follow the Anthropic announcement? (way too technical IMO) Here's a demo:

This weeks' skills changelog: - /ubiquitous-language deprecated, use /grill-with-docs instead - /grill-with-docs for codebases, /grill-me everywhere else - Skills can now be used with any issue tracker - Experimental /diagnose and /triage skills

Frontend is WAY harder for AI than backend. That's because it's flying blind. It can't test the code in the environment where it's running - the browser. Here's how to hook up AI to your browser:

Claude Code: "npm add ..." You: "Use pnpm, you idiot!" *adds it to CLAUDE​.md* Claude: "npm add ..." There's a better way:

Everyone who's worked with AI a lot agrees: LLM's hallucinate. A LOT. But to this day, I see friends and family trusting ChatGPT blindly, whether it's is working off retrieved data or not. So, I made this. Share it with anyone who you think trusts AI too much.

I'm building an app from the ground up, and I'm filming every part of it. It's called Slopwatch. It's a great way to pick up tips for using AI Coding tools like a real engineer. First step is choosing the language. Rust/Go? Node/Bun? Only way to find out is to /grill-me.
