Here's my in-depth guide to getting the most out of Claude Fable 5, so you can build things as insane as my demos below. simplemarkdowneditor.com/pub/IbaCrTjLJT…↗

@humblyonline 90% of people can delete their AGENTS.md and their output will improve. Use it as an index of pointers to important files, and even then aggressively prune it for no-ops. How's that for vague↗

Fable 5 has been re-released with 50% weekly usage. Copy my output-optimized Fable stack that doesn't burn tokens like crazy: > [I explain the task] > explore - scout agent (Opus, low) > plan - Fable high > [I review the plan] > implement - Fable medium > diff review - Opus hig…↗

Give your agent its own computer to REALLY end to end test stuff.↗

a fun workflow for prepping a talk: > record a draft video without a script > have Claude Code turn the video into a Notion page with slides + transcript of what I said > ask people for feedback on the video; Claude processes their notes and attaches things as inline comments in…↗

TL;DR ELI5 of @trq212's new article: Claude isn't the bottleneck anymore. The stuff you forgot to tell it is. Your prompt is a map. The codebase is the actual road. Every pothole you didn't mention, Claude fills with its best guess, and the more work you hand it, the more it has…↗

figuring that out with Fable now, i first started by just brain dumping everything that i want to have agents running for i think this might turn into an Executor feature of 'Agents' where you store a: - name - goal - allowed toolset and then it just handles dispatching an API…↗

fable produced 60+ (!) ready to merge prs for @mainframe overnight. here's how you can set up a software factory using fable as an orchestrator. prompt included! 1. narrate your *entire* todo list — everything that's top of mind — using dictation. i used @usemonologue and my p…↗

i've got codex... - reading all my emails to figure out proposals to write, directly in google drive - auto-drafting contract redlines that i can check with my lawyer on - using computer use to add into docusign for me - reading slack feedback channels to auto-fix bigs - writing…↗

I wrote down how we made our codebase work for agents in remote machines. Orb setup, custom dev server tooling, /__dev endpoints for auth, log tricks, 41 AGENTS.md files. It's all in here.↗

Every time you think you need a dashboard to look at data, stop yourself. Do this instead: 1. Ask your agent to make sure that you have all the data to analyze something actually stored in the database. 2. Ask your agent to write a skill to gather that data. 3. Ask your agen…↗

Want to try GLM 5.2 in production but worried how it might change your product? Don’t worry, we got you: 1. Install Inference Gateway (docs.inference.net) 2. Keep sending traffic to your current provider 3. Gateway automatically starts sorting through your live data using an RL…↗

New skill: /animation-vocabulary Helps you get better animations from an AI by telling it exactly what you want by using the right words. "morph", "rubber-banding", "layout animation", and more.↗

Doing my first ever experiments with a personal, entirely agent-managed Karpathy-style wiki X, Discord, Gmail are all being ingested into it every few hours This is the knowledge base that will serve as the environment for all of my future loops↗

🌀 "loops" are nothing new, but they take thoughtful consideration to build durably. This is a quick look at how I'm thinking about loopcraft, building durable loops from scratch, and experimenting with Pi, Herdr, and @theo's Lakebed (a shitty cloud for shitty apps)↗

Human in the /loop What I like most about coding with agents right now is the room to leave a few runs going and still get on with other work. When something finishes or needs a call, I show up. This post is a short explainer of the setup I use, a definition of done the agent c…↗

Pro tip: when building complex workflow skills with codex, prompt your agent to leave feedback in a dedicated file in tmp as it runs into workflow papercuts. It makes iteration a lot easier!↗

5 steps to create amazing videos like the one below from HTML for free: Install @HyperFrames_ in your favorite coding harness (e.g., Codex or Claude Code). Then... 1. Gather your assets Create a project folder and add screenshots, logos, website captures, reference clips, and…↗

How I migrated to the new computer? Started a thread on previous, asked a bit of inventory for custom setup and code repos, etc... Copied Codex home (75 GB) on new computer. Launched Codex app, resumed the thread, asked Codex to rebuild my computer the same. Done.↗

Show Codex a workflow once. Reuse it as a skill. Record & Replay lets you show Codex a recurring task, like filing an expense report or submitting a time-off request. Codex turns that demo into an inspectable, editable skill. You control when recording starts and stops.↗

1. as a mental model it is more correct to think of fable+ class models as english -> code interpreters - converts your idea into code into "correct" code regardless of problem complexity and output complexity (diff size). Fable 5 will be the worst of this new class of models 2.…↗

My heuristic is that any diff an agent generates over ~1500 lines is too big and is indicative that the problem needs to be decomposed. This is my general pattern now for feature work: 1. Try to implement the whole feature, loosely guided. I call this the "draw the owl" prompt i…↗

Mastering Codex (Mobile) for Engineering How to turn your phone into a Codex control center?? At first glance, it looks like a way to check on a Codex task from your phone. That is useful, but it misses the bigger idea. The power of Codex Mobile is that it lets you start, direc…↗

Loops so hot right now Here are the loops I’m experimenting with: Planners - morning brief, orient and context switch back into the flow. This pulls from outside data sources and also checks past chat logs to figure out our current progress. - daily planning - what did you get d…↗

Claude Fable can run autonomously for days. This is the single highest-leverage prompt I use to stay on top of it: "Spin up a persistent HTML page. As you work, append clear, timestamped updates with screenshots/media so I can follow along." Literally a 10x better experience.↗

Lots of people asked how I used Fable to edit its own launch video so I made a video about that! TLDR it wrote a lot of code & tool calls to use transcription services, ffmpeg, do colorgrading, use the figma mcp, make remotion UI and render it. I didn't touch a video editor.↗
