@MatthewBerman — Anthropic's guide on building effective agents
Anthropic just dropped an incredible guide on "How To Build Effective Agents"
2025 will be the year of AGENTS 🤖
Here's everything you need to know: 🧵
The thread title is a bit much, but the underlying Anthropic guide is actually worth reading — it's one of the more grounded pieces on agentic system design, covering when to use single agents vs. multi-agent pipelines, how to handle tool use, and when not to reach for agents at all. The "year of AGENTS" framing will age poorly, but the guide itself won't.
@dshukertjr — Supabase auto-generates TypeScript types from your schema
Supabase can automatically generate TypeScript types for your database schema!
This allows you to write Supabase queries in a type-safe manner, keeping your client-side code in sync with the database!
Useful if you've been manually maintaining types or relying on the Supabase dashboard. The supabase gen types typescript command outputs a types file you can import directly — your query results get proper inferred types instead of any. Keeps the DB schema and client code in sync without any extra tooling layer.
@antonosika — two failed launches, then $5.3m ARR in 5 weeks
We failed 2 launches 2024. The third time was the charm – $5.3m ARR in 5 weeks.
This is the story:
//1
Anton Osika is the founder of Gpt-engineer (now Lovable), and this thread covers what actually changed between the launches that didn't land and the one that did. The $5.3m number in 5 weeks is genuinely unusual — not the "we launched on Product Hunt and got 1000 upvotes" kind of launch. Worth reading if you're building any kind of AI-native product right now.
@nandafyi — Interactive SVG Animations course is live
Interactive SVG Animations is now live!
Everything I know about SVGs, distilled into five modules covering everything from syntax, advanced SVG features, peformance characteristics and more!
You can preview the first lesson right here (desktop-only atm!) https://svg-animations.how/preview
SVG animation is one of those skills that looks intimidating until you learn that most of it is just path math and SMIL or CSS transitions. Five modules with a browser-based preview is a solid structure — you can see the output as you go. The performance module is the one I'd actually pay attention to: SVG animation performance traps are subtle and easy to ship to production.
@rauchg — UI pattern for showing model reasoning
Want to see this UI pattern applied to the thinking tokens of O-style models
More entertaining than "🌀Thinking"
Short take, but a real UX problem. The default "thinking" spinner on reasoning models is useless — you're waiting and seeing nothing. Exposing intermediate reasoning tokens as readable text (or even collapsed but expandable) would actually communicate that the model is working on something non-trivial, not just lagging. Guillermo's right that "🌀Thinking" is a placeholder waiting to be replaced.
@serafimcloud — 21st.dev adds "Copy Prompt" for AI app builders
Building modern apps just got easier! 🚀
With @lovable, @v0, and Bolt running on @stackblitz, the new 21st (dot) dev "Copy Prompt" feature is here to save you time.
📌 See something cool? 👉 Grab the prompt for your platform. 👉 Drop it in your chat.
Boom—you're up and
The "Copy Prompt" feature on 21st.dev is a small but sharp idea: see a UI component you like, click to get the prompt that would generate it in your platform of choice (v0, Lovable, Bolt). It collapses the "I saw this thing and want something like it" → "I have a working component" loop. Small friction reduction, but that's exactly the kind of thing that gets used.
@marclou — December 2024 revenue breakdown
I made $268,463 in December 2024.
🧑💻 CodeFast — $219.2K ⚡️ ShipFast — $43.1k 🍜 Indie Page — $1.9k 📈 DataFast — $1.1K 🚀 LaunchViral — $1K 💨 Zenvoice — $700 🎞️ YouTube — $455 🐥 Twitter — $353 🛡️ ByeDispute — $270 🌱 HabitsGarden — $253 💩 PoopUp — $84 📚 WorkbookPDF — $48
🟢
The interesting part isn't the total — it's the distribution. CodeFast alone is $219k, which means the entire portfolio is essentially one product with a long tail of experiments attached. ShipFast at $43k is the second engine. Everything else is noise by comparison. This kind of public breakdown is rare and useful: it shows what "diversified indie revenue" actually looks like in practice, which is usually "one thing that works and everything else is a rounding error."
@rileybrown — AI writing app built with Cursor Agent, zero code
I built an AI powered writing app with Cursor Agent without writing a single line of code in a little over an hour.
Features:
- AI powered autocomplete
- AI powered image search with autosuggestions based on what i'm writing
- Ai powered research based on what i'm writing
"Without writing a single line of code" claims age fast, but the demo is real — Cursor Agent can scaffold and wire up a working app with AI features in an hour if you're running on happy-path requirements. What this actually tests is the agent's ability to pick reasonable defaults, not your ability to build. Useful benchmark of where Cursor Agent is right now.
@ky__zo — snippet to save time in 2025
this little snippet will save you 128 hours in 2025.
bookmark for later.
The "128 hours" claim is made up — it's a marketing number for a code snippet. Still saved it because the underlying technique (based on the image in the thread) is worth knowing: it's a short shell alias or script pattern for a repetitive workflow. Whether it actually saves 128 hours depends entirely on how much you do that workflow. Classic overpromise on the packaging, possibly solid on the contents.
