personal agents, the end of friction, economic consequences of finally getting around to it

On Tuesday, Sierra announced Personal Agent Protocol with Meta, Genesys, Instinct, Rocket, Shopify, Stripe, and Walmart. The response has been incredible and today we’re publishing the first draft of the protocol at personalagentprotocol.org and announcing 35 new design partners.
As personal agents take on more, our goal is simple: consumers have choice and control, and companies know when they’re dealing with an agent and who it represents.
This draft is a starting point. We’d love for companies, developers, and personal agent builders to read it, give feedback, and help us build an open standard together.

Today we’re announcing Personal Agent Protocol — an open standard @Meta and @SierraPlatform are developing along with industry partners at @Genesys, @instinct, @RocketOTD, @Shopify, @stripe, and @Walmart. It will help define how personal agents interact with businesses and is open for anyone to implement. You can read more here - and if anyone is interested in joining let me know! sierra.ai/blog/introducing-p…
The new “iPhone” is not the Duo. Some thoughts on why: benhadden.com/posts/converge…

Translation: 2026 is the year of personal agents, aka Linux desktops in the cloud, and OpenAI is building one.

Asking Instinct to create an image of me in all of the clothes it recommends is my new favorite use case. I hate shopping for clothes (research, trying on, ordering), and this makes it so much easier.

Having a hard time articulating why I prefer Instinct (@noahrshinn) over Muse at the moment. I think it's a combination of personality and the fact that Instinct is not an app. Interacting with Instinct purely through iMessage feels simpler, more magical, and more natural.

Instinct would be a lot more useful if it became friends with @1Password. Not really a fan of giving my passwords to another service.

The delta between an Uber driver rated 4.98 and 4.91 is vast. Those 0.07 points reveal themselves almost immediately.

“Our bet is that these products become more like backends over time, with the agent as the primary interface.” So true. ❤️ Pinecone.

Why does Apple still charge $99 + TestFlight hoops to run an app you built for yourself? Shortcuts is too limited, the App Store is overkill. Where’s the tier in between?

Today, Sierra is releasing Ghostwriter, our agent for building agents. With Ghostwriter, you can create an AI agent for your customer experience — one that can chat, pick up the phone, speak dozens of languages, take action on your systems of record, and be protected with industry-leading guardrails — simply by having a conversation. No clicking, no forms, no menus.
Codex and Claude Code have transformed how we build software, making it possible for software engineers to orchestrate and review the work rather than doing all the work themselves. We think the same transformation will happen for all software. Rather than every enterprise app having a web app for humans and an API for automation, every software platform’s UI will be an agent that can do the work on your behalf.
I recorded a demo of my building and optimizing an agent with Ghostwriter so you can see how powerful and easy it is to use. It’s completely changed the way our early adopters build agents, and it’s changed the way I think about the software industry. Let me know what you think, and, if you’re interested in trying it out at your business, please reach out directly.
Thank you for the vertical tabs @googlechrome. Long time coming, and it's great. Now, please ship a keyboard shortcut to expand and collapse the side pane! 🙏

Can’t wait to see how @benthompson weaves together Block’s layoffs, Anthropic’s standoff, and OpenAI’s round into Monday’s post. The raw materials for next week’s content came fast and furious at the week’s end.

I know that pairing @claudeai (Code) and @obsdmd is the new hotness, but don't underestimate pairing Claude Code and @culturedcode (Things). They work together magically.
