Have been trying for weeks to make AI better at course planning Tried a new method today. Notecards, pen, paper, scissors. Turns out not using AI is pretty good guys↗

I've been trying to use AI for knowledge work (course planning). Here's what seems to work so far: 1. Give each 'deliverable' a Karpathy-style LLM-wiki (for me, a deliverable is a course, or a talk. A sizeable piece of work, more than 1 day's labour) 2. Split the deliverable i…↗

mattpocock/skills v1.1 is out! - /wayfinder helps you plan more ambitious work than ever - /to-spec and /to-tickets replace /to-prd and /to-issues - /implement + /code-review complete the whole lifecycle - /research and /prototype help support wayfinder, or can be used independe…↗

Here's a step-by-step process to kill all the bloat from your Claude Code system prompt: 1. Run a proxy so you can see exactly what gets sent to Claude Code (included in the article) 2. "Fuck, there is so much cruft in there" 3. Use my settings.json to kill all the bloat Down t…↗

Getting sick of setting up third-party services So I built a skill for it /wizard builds you an interactive CLI for the task you're currently doing, and takes as much work off your hands as possible #1 is how the agent described the wizard, #2-3 is what it looks like:↗

Just recorded my AIE SF talk remotely, and I'm sad that I won't get to have a corridor Q&A. My talk's called "The Missing Manual: How To Write Great Skills" So, AMA. What do you want to know about writing better skills?↗

Take a look at your favourite skill. Go on, take a look. Check for lines like: - "Make the commit message very detailed" - "Be thorough" - "Make the implementation easy to read" What do these lines have in common? They're no-ops. They do nothing to change the agent's behavio…↗

I have a deep distrust of almost any 'self-improvement' loop in coding agents I.e. automatically created memories, CLAUDE.md suggestions applied after every session Often the suggestions themselves are shit But even if they're good, the agent often over-indexes on them in a wa…↗

I poured my 10 years of teaching experience into a skill. It's called /teach, and it can teach you anything. Here's how it taught me to solve a Rubik's cube:↗

One thing people underrate about the smart zone: It's a great way to save on tokens. When you're in the dumb zone, sending 600K tokens on every request gets expensive FAST Yes, you get charged for cache hits. Less, but it still adds up.↗

This is the clarity we've been crying out for. But it's a poisoned chalice. This is a 10X cut to claude -p disguised as a monthly bonus. Anthropic is discouraging any kind of programmatic usage. And that's fine - no subsidy lasts forever. But it's time to try Codex.↗

The more I replace plans with prototypes, the better the outputs Who'd have thought that low fidelity prototypes were better than walls of spec Oh yeah, the entire industry for 20 years Stop going against decades of knowledge because someone in SF shipped it as a 'mode'↗

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.↗

Personal software is INSANE in the age of AI I use mine to: - Manage my course videos/material - Use AI to help me write accompanying text - Use AI to transcribe my videos WHILE RECORDING Folks who know how to build have a crazy advantage↗

Instead of markdown files, I've been getting my AI to save plans in GitHub issues. Claude Code is AWESOME at using the GitHub CLI. Means you don't have endless THROWAWAY_PLAN.md files spamming the repo.↗
