Playing around with clawdbot, calling mine Jeeves. What did you name yours?

Context doesn’t just help AI answer. It helps AI aim. Prompting is the workout. Context is the coaching.

If you prompt AI with only the “2,000m” equivalent (the task), you’ll get a decent result. But when you add context (settings, benchmarks, comparisons, constraints) you get a better result faster.

Real-world example of why context matters when working with AI 👇

Is it possible to vibe-code a legit million dollar SaaS?

@JohnnotJon Airpost

Today, we’re launching Airpost. I’m 46. That’s not a cool age to found a startup. At least according to Twitter. I still call it Twitter. I’ve loved advertising all my life. Since I was 19 and my mom told me about a movie called “Nothing in Common” with Tom Hanks where he plays an ad exec whose main job seems to be shooting hoops with his creative partner. That sounded fun. Since then, traditional advertising has stayed… traditional. From my 1st job out of college writing TV ads for Snapple and Fox Sports, to leading product marketing at Airbnb, I’ve seen a lot. Now the AI era is here and an entire $1T industry is about to change. Who will change it? Why not me? Why not us? Introducing Airpost: a platform and service where world-class creative strategists use custom-built AI to build video ads. Fast. If you’ve ever sat down to make an ad with AI and realized 20 minutes later you’re still wrestling with that same clip… that’s why we built Airpost. Growth teams are busy. They’re asked to do too many things as it is. They shouldn’t have to be AI experts as well. Creative strategists shouldn’t have to stare at a white box trying to decide what to prompt. They should have a partner. That’s what we aspire to be. And that’s what we’ve built our tech to do. AI ads shouldn’t have to mean only AI footage. We have an exclusive library of over 300,000 video clips we’ve shot ourselves. Our engine uses these, along with client footage and AI footage to make the ads we deliver each week. We’re funded by the best investors and humans we know. We bootstrapped our performance creative agency, Ready Set, to 200 people. I was always told VCs didn’t add value. If that’s true, it must be other VCs, because ours have been awesome. Thank you Zach Perret, Nate Abbott, Peter Hebert, Max Mullen and all of the firms and folks who’ve believed in us so far. We’ve gone from 0 to $1M ARR in the six months since we quietly started working with early clients like DoorDash, Dr. Squatch, Calm and more. So far, every customer has renewed. To celebrate the launch, we’re giving away a superagent where you: 1) Put in your product URL 2) Get snippets of what your real users are saying on Meta, TikTok, Reddit and X 3) Paste them into ad scripts Comment “Airpost” and I’ll DM you the private link. It feels (a little scary but) good to be out there. Here we go! 🚀

@rfgarcia See if @usehallway is headed in the right direction for you. We just hit 50 on our waitlist. Opening the beta soon.

Feeling bearish on agent frameworks as they are currently defined… 2025: an agent is an LLM calling tools in a loop. Lots of frameworks built around this concept. 2026: an agent is Claude Code (or equivalent) in a VM, with useful programs (CLIs, browser, MCP servers), and a bunch of markdown (skills, commands, AGENTS .md) I want a framework that treats this as the primitive—not the LLM-with-tools abstraction

@bprintco Sounds like you should @usehallway

I see a lot of people posting about replacing their CRM with something they vibe coded. That’s cool. I love it. But what I haven’t seen yet is someone actually reimagining what a CRM should be in an AI world. Right now everyone is just rebuilding Salesforce with prettier buttons. I don’t want a better interface. I don’t want more dashboards. I don’t want another place to click around. I want a completely different way to interact with my business. I don’t want to: - search for a customer - open their record - pull up their estimate - copy/paste my line items - checkbox attachments - click send I want to pull out my phone and say: “Send John Smith an estimate for 3 acres at tier 2 brush density and tier 1 terrain.” And it just does it. Or: “Follow up on all pending estimates for the next 30 minutes. Give me a quick summary of each job and connect the call.” Or: “Which customers haven’t paid in 14 days? Text them a reminder and flag the ones that don’t respond.” Or: “Who are my top 10 repeat customers? Draft a thank-you email and a referral offer.” Or: “What jobs next week need equipment mobilized? Notify the operators and update the schedule.” That’s the CRM I want. I don’t want a Salesforce clone. I want someone to take this to the next level. There are some absolute killers out there right now building insane things. Someone is going to crack this. Build that please.

The people who wait until AI is "ready" will be starting from zero. The people using it now, mistakes and all, are building judgment you can't shortcut.

Here's the catch: this skill only comes with repetition. The easiest way to start? Next time you reach for Google, ask ChatGPT or Claude instead. You'll get some great answers. You'll get some wrong ones. And slowly, you'll learn to tell the difference.

AI isn't perfect. That's exactly why you need to start using it.
