Screenshot of an excerpt from a Buzz press release that says: “Building on Nostr We chose Nostr because it solves the most fundamental problem in multi-agent collaboration: identity. Every participant, human or agent, holds a cryptographic keypair that belongs to them, not to the platform they happen to be using. Agent identity isn't tied to a platform account or an API key managed by a vendor. It's portable, verifiable, and independent. The agents you build and configure in Buzz aren't locked in. They can participate across any Nostr-compatible system, and their identity, their history, their reputation, travels with them.”

My LinkedIn 🤢 post that says: In a world where "anyone can just build something", I'm a lot less interested in whether you *can* build something with an AI tool, and a lot more interested in *why* you built it, and why you built it *this way*. I want to know... 👤 Who this is for (users) ❤️ What fundamental set of problems it solves for them (scope) ⭐ How it's uniquely valuable (differentiation) 💗 How you'll expand on that value (growth) 🧭 What you hope it will become (vision) 🎯 What you said no to (focus) ⚖️ How you balanced constraints (tradeoffs) 💰 How you'll benefit (business model) 🏡 How it will serve your users and society (responsibility) 🗺️ How you'll methodically evolve it over time (roadmap)
A screenshot of an interaction with Claude, where I say “lol shush claude” and it responds with “Fair. You know where I stand. Do your thing.”
A screenshot of the Claude.ai interface showing a conversation on the left and a React artifact preview on the right. The artifact displays a "Topics & takeaways" tracker with a nested card-based layout — topic cards with status badges (blue "Active" and green "Resolved") are indented to show parent-child relationships, connected by vertical lines along the left edge. Each card shows an outcome summary and inline sections for decisions (with green checkmarks), next steps (with checkboxes and blue "Copy" buttons), and open questions (with red question marks and blue "Ask" buttons). A Topics/Takeaways toggle sits in the upper right of the artifact. The conversation pane on the left shows Claude's change notes for this version.

A text post in large gray serif typography on a light background that reads: “When people tell me, ‘I love Bluesky, and I’m glad you’re involved,’ I sometimes answer, ‘I love it too—and did you know that Bluesky is one app of many in a network called the Atmosphere?’ This has gotten me 100% blank stares. But yes, it’s true. There are lots of other apps in the Atmosphere. Expect me to talk a lot more about that in the coming weeks and months.“​​​​​​​​​​​​​​​​
A large framed wall advertisement for Appian, taglined “the process company,” in what appears to be an office or conference center hallway. The ad reads “Modernize mission systems with AI-powered process technology.” in white text over a dark gray background, with a photo-realistic fighter jet (appears to be an F-16) on the right side. A curved white swoosh graphic connects the text area to a darker semicircle containing the Appian logo at bottom left. Drop ceiling with fluorescent lighting visible reflected in the glass. Commercial carpet tile floor.​​​​​​​​​​​​​​​​

Screenshot of a music player interface with a black background. At the top, there are status icons for time, battery, and connectivity. Below, tabs labeled "Now Playing," "Details," and "Bookmark" are visible, with "Now Playing" selected. The album cover features a stylized illustration of a person wearing sunglasses and a cap on an orange background with the text "HEAVYWEIGHT." Below the cover, the track title "#66 Deborah" and artist "Heavyweight" are displayed. A progress bar shows the song duration from 41:18 to -05:14, with a white play button in the center. Control icons for skipping back 10 seconds, pausing, and skipping forward 10 seconds are positioned below the progress bar. At the bottom, a navigation bar includes icons for notifications, favorites, upload, checkmark, and more options.

Screenshot of a Bluesky profile page with a photo of a man wearing a green cap and glasses. The background shows a cozy room with a window, a bench with colorful pillows, and a patterned armchair (it’s the set from Mr. Rogers Neighborhood). The profile displays the name "Peter Lewis" with the handle "@peterlewis.design," along with follower and following counts and the number of posts. Below, there's a bio describing him as a principal software designer in healthcare.
Black text on a white background reads "Conclusion" followed by a paragraph. The paragraph reads "Stop thinking about agents as if they're just an LLM. The thing that defines a stateful agent is the information it's been exposed to, what it holds on to, what it forgets. All that changes the direction that it evolves into. Stateful agents are self-referential information processors. They're highly complex for that reason."

Screenshot of text from an article by Dave Kiss that says: Watch how experienced engineers actually work with these tools. They rarely type a prompt and accept whatever comes back; they plan first. They tell the LLM to ask clarifying questions before writing any code. They request architectural diagrams, implementation plans, a clear breakdown of the approach. They use something like beads to track the work in epics and tasks, blocking things based on what needs to happen sequentially. They define the shape of the solution before the agent writes a single line. This is the opposite of vibes. This is structure, intention, a very clear definition of the approach the LLM should take, the constraints it should work within, the patterns it should follow. The planning itself is the work now, and the execution is what the agent handles.
Screenshot of text that reads: "Here’s the thing though: the more I actually use AI tools, the less I believe the sensational narratives. Both the utopian ones AND the dystopian ones. Remember when computers were going to take all the jobs? When ATMs would eliminate bank tellers? It turns out inventing new tools doesn’t typically result in mass unemployment - it just changes what work looks like. And if my year on a team heavily using AI has taught me anything, it’s that there will always be more work to do. There is no “end of the backlog.” Doing work begets more work."

Screenshot of an article excerpt about Threads' growth strategy, showing text with yellow highlighting on a quote from Hayes (the head of Threads) explaining the goal is to "get people off of being dependent on those promotions and wake up in the morning and just want to open the app." The surrounding text describes Meta's playbook of surfacing personalized Threads content in Instagram and Facebook feeds to drive downloads, then weaning users off those nudges.
