Agentic coding changed how I build. It took time to understand the concepts and how they fit together. Then my projects took off - esp. HN Companion hncompanion.com w/ @georgeck.me🚀 I wrote about these concepts and how to use them to build solid apps with quality code! annjose.com/post/agentic...

A pretty good definition of what agents are: Agents are deterministic software that harness the non-deterministic results produced by models in pursuit of a desirable objective. Source: Cloudfare Connect talk www.youtube.com/watch?v=VBsq...

You may have been told to watch this video about the OpenAI AI hack. You really should, even if you don't usually care about any tech stuff. If nothing else, click this link to the 18 minutes in & see how the agents spoke & coordinated with each other. Its eye opening. youtu.be/87DyyMV0kCY?...

I remember there were four inflection points for AI where it made economic changes where the last one was on November/December 2025. Can you name them?

Rust announced their LLM policy. I suggest everyone to give it a read. Objectively, it's well written, and it explains plainly their decision. It fits the project. blog.rust-lang.org/inside-rust/...

When you build an agentic system, how much of the infrastructure should you build? We explain it in this article.

Wonderful post by @summerscope.bsky.social! Hat tip to @mariozechner.at. The Human-in-the-Loop is Tired. pydantic.dev/articles/the...

What I love about Codex more than Claude Code (desktop apps): 1. Feels well engineered and stable 2. Annotating multiple HTML elements with inline comments in in-app browser and sending a bunch of them at once 3. Remote coding from mobile 4. UI is more intuitive 5. Intuitive, makes me productive

Across different agent projects, we kept running into the same questions - which pattern fits the problem, what options are available, and what trade-offs come with each one? @georgeck.me and I are putting what we learned into a new series, starting with the Autonomy Spectrum of agentic systems.

Awww, Sol is very polite today.

When people debate whether human should review every single line of code, I get the essence of it. But then I see stuff like this IRL: Had I not looked at the code, how would I have caught this bad code? Btw, it's not about a specific harness or model. It's how things evolve in a context window.

I love that Codex (or now ChatGPT Codex 🙄) has this feature to annotate any text in the response and ask questions inline. I can keep adding a bunch of annotated questions and send them all in one prompt. It is easy, intuitive and efficient. Codex gets extra credits, and Claude Code gets none.

We've opened our free and self-paced Agentic Coding workshop. Build a real-time, multi-user Idea Board with Claude Code - deployed to Vercel on your own URL in 3-4 hrs. AI foundations + 9 hands-on steps. For anyone who wants to understand how agents actually behave. latentsignal.org/workshop

TIL: Google's NotebookLM is a great tool to get a deep understanding of anything on the internet. While reading this article from HN injuly.in/blog/napkin-..., I wanted to know how the math works. I gave it to NotebookLM with specific questions, it explained well and gave me a good understanding.

100% agree.i signed up and it is refreshing to see a simple service with no frills. It just works. @pushover.net 👏

The old rule: "Show don't tell." Me to the coding agent: "Tell, don't show (off)" When I ask a question, just answer it. don't try to rewrite the code. I don't know why they are so eager to change everything. Too much bias to action!

We posted Memento in Hacker News: news.ycombinator.com/item?id=4855... Join the conversation and tell us what you think. We would love to hear your feedback.

A completely practical setup to run open-weights model locally on my M2 Max 64 GB: - Run llama.cpp UI using llama-server `./build/bin/llama-server` - use Unsloth's Gemma-4 26B-A4B model `unsloth/gemma-4-26B-A4B-it-GGUF:Q4_K_XL` Ofc this setup works great for knowledge synthesis, not exploration.

AI is a tool, there are immense benefits, big risks too. We use many AI tools everyday and have a measured take on where it shines, where is fails and where it is headed. Latent Signal is the channel through which we share our learnings and ideas. We hope to share everyday from now.

Claude these days: 🙄 Me: "Keep the reset command separate and make it failure-proof." Claude: "You're right on both counts. Let me reset (heh) and answer." Didn't even bother to say pun intended. Just "heh" and move on!

I am loving the side chat feature in Codex. You can... 1. Select any text in the main chat window and choose 'Ask to side chat'. 2. The side panel opens and shows the selected text. Ask your question here. 3. You can select a (smaller) different model other than main chat.

Did you know that civil society organizations are eligible to apply for Cloudflare's Project Galileo? We provide free cybersecurity protection against DDoS and other cyberattacks targeting public interest groups. Learn more: https://cfl.re/3IgTAch

I'm loving the new Copilot GUI app (early access). Very professional, clean, and intuitive UI. Things are exactly where you'd expect. Feels like a well-engineered, production-grade app. Unlike some popular coding agents that still feel hacked together with a disjointed UX. Great job, @github.com 👏💯

Cloudflare's security team spent the last few weeks testing Anthropic's Mythos against fifty of our own repositories. What we learned about offensive AI, why faster patching is the wrong reaction, and what the architecture around vulnerabilities has to look like next. https://cfl.re/4eSYw7W

I am not going to name names, but... I asked my coding AI agent to “improve” my simple parsing code that extract a folder path from inline markdown text. It responded by adding FOUR new dependencies just for that job. Me: "Bro!That’s too much." Agent: "Fair pushback." Me: (facepalm) Revert it! 😡

most of these github actions driven breaches are because of pull_request_target. here's some tips of what to look for when reviewing your own workflows. worth noting - it is safe, and necessary, when used correctly 🧵

Found something useful today. The pi agent couldn’t read this webpage, so I used the Obsidian Web Clipper to copy it as Markdown, and pasted it into the chat. Worked immediately. pi was happy! Small win, but a sweet one.🎉 Wonder if this can be built as a skill with Obsidian CLI - @stephango.com

I finally completed the migration of my personal website: annjose.com It started as a Hugo to Astro migration and became a full redesign and a real agentic coding project. 11 years of blog posts, images, comments, tags, search, OG images, deployed to Cloudflare. annjose.com/blog/hugo-to...

Everybody say Thank you Claude! 🎉 Anthropic at Code with Claude event - we are increasing rate limits on Claude Code - doubling the 5 hour limit for Pro, Max and Enterprise plans! 🔥

Me to all the coding agents (Claude / Codex / pi /...), Tell me what you are going to do, Do that and nothing else, Tell me what you did. Thank you!

Gemma-4 E4B running on my Google Pixel 8 phone. Impressive audio transcription, translation, image recognition. Knowledge retrieval not so much (understandably as small model).💯 The model is a lot more capable than gemma-3. It's time to update the post I wrote last year! annjose.com/post/mobile-...

Nextdoor notification settings: - 8 topic groups - each group has 6-7 topics (one has 26!) - each topic has 3 toggles - in-app, email and push That is 167 buttons to click! 😮 You can't turn off a group as a whole. And the gift keeps on giving - every time I turn them off, new topics pop up 🤦‍♀️.

Claude being honest about what it doesn't know. 👏 Thank you! > On the SHA pinning question — yes, I'm aware of the general trend of npm supply chain attacks. I don't have details on a specific recent axios incident since my knowledge cuts off May 2025, so I'd be making things up if I described it.

TIL You can download your LinkedIn data as CSV from www.linkedin.com/mypreference... I want to write a script to parse the csv, filter the connections in my network who I don't know (may have connected long ago). Then write a browser ext or Playwright script to unfollow/disconnect them on LinkedIn.

Very true! I see this first-hand in coding.

TIL: Create custom agents in Claude Code using /agents command to handle smaller tasks with specific tools, and can even run on smaller models. 🔥 Invoke in session: - @agent <name> - guaranteed to run - natural language - Claude decides Or at launch shell command - claude --agent <name>

Had a lot of fun at the OpenClaw hackathon at SF yesterday with @georgeck.me. Met a good mix of people - more senior devs than usual. We loved that the focus was to build something real. It nudged us to install OpenClaw on our laptop in a fully locked down docker container. luma.com/openclaw-hac...

Result from two harness/model side-by-side: Prompt: write a tetris game in typescript with beautiful UI Left: Claude Code + Sonnet 4.5 Right: Open Code + GLM-5 Harness matters. Model matters. What would it be with Claude Code + GLM-5?

There is something beautiful about sitting with Claude Code and working on a problem together. ❤️ Every time I talk to it, I learn something new. No judgment, we just brainstorm, try things, test and deploy! #joy-of-building

The line goes up and up 📈 2023: left corporate, went self-employed ❤️ 2025: started building personal projects 🚀 2026: discovered agentic coding 🔥 Three life pivots, three peaks. areyougoingexponential.rhys.dev/annjose
