My agent just spit out a bunch of Chinese symbols. Turns out they are Chinese gambling spam that managed to get into the #OpenAI training data or something? In any case, yet _another_ per-model quirk to overcome - my end users don't need to be shown gambling spam in _any_ language 😀

My #RockBot agent and framework now has its own domain - starting to come together into something people can use! What is it? The RockBot _agent_ is an autonomous personal/professional assistant. The _framework_ is a rich toolset for building your own agents in #dotnet. rockbot.dev

These days I find myself doing nearly all my work with "pure" Claude Code plus a few skills. I don't use the plugins I used to anymore. blog.lhotka.net/2026/04/23/M... #ai #agentic #softwaredevelopment #claudecode

building #ai agents that call tools reminds me of all the browser-specific caveats. It seems like every LLM (even in the same family like #gpt) has its own quirks as to how it formats tool calling output, requiring LLM-specific tweaks. It is the bad old days of the browser, in LLM form!

If you’re building agents, understanding the Harness-LLM loop is essential. A lot of what looks like “the AI being confused” is actually the Harness not providing the right context at the right time. blog.lhotka.net/2026/04/22/A... #ai #agentic #agent

It is easy to get so wrapped up in #ai and #agentic work that I lose sight of the reality that _most_ organizations aren't yet formally building agents. _Humans_ (end users) are often using unsanctioned AI, but _orgs_ are still being cautious and (as always) are moving slowly.

Donald Trump just threatened to unilaterally destroy an entire civilization. Is there genuinely no limit to what Republicans will allow this unhinged, unwell man to do? Congress must come back to Washington to rein in this dangerous behavior immediately.

Today is a big day: the second instance of #rockbot is now running in the wild! So now I know for sure it can run outside my own personal #kubernetes cluster 😀 In this case, my buddy is running it in a #docker compose environment against a local #ollama LLM, which seems to work great!

#ai is upending the #softwaredeveloper job, and I believe "systems thinking" is one of the core skills people need to embrace to ride this wave to success. blog.lhotka.net/2026/04/02/S... #claudecode #github #copilot

All the big #ai #llm models seem to close replies with an offer to do more to help. The #openai #gpt 5.3 model though, forms these offers as click-bait. Very annoying, and hard to overcome with just directives. It seems built-in to be irritating.

WebAssembly offers strong isolation and sandboxing for AI agent-generated code, solving security risks that containers and microVMs struggle to address.

#ai and #agentic systems use skills and tools. I keep hearing people pit these against each other, but really they are complimentary. blog.lhotka.net/2026/03/25/T...

GPT‑5.4 mini is now live in GitHub Copilot — and it’s ridiculously quick. Faster first tokens, smarter repo exploration, and great grep‑style reasoning. Works across VS Code, Visual Studio, JetBrains, Xcode, Eclipse, GitHub.com, Mobile, and the CLI. Let your workflow breathe. Blog: buff.ly/2ltfNBL

You learn a lesson, then get lazy. I _know_ you need to test backups. If you never do a restore, you don't _really_ have a backup. Fortunately in this case, all the data was temporary, so the failing backup just revealed that I _could_ have been burned badly. Fixed now.

@bradygaster.bsky.social I'm trying to use squad and it keeps doing just a little work and then wants my input - how do I get it to run to completion?

It is *fascinating* to me how quickly some people have gone completely from “we all must work in the office! human collaboration is vital and only happens in person!” to “I can replace all these pesky people with chatbots!” Definitely some commentary there about our society and who gets to choose.

I develop using the #claude models continually and extensively. I'm running #rockbot against an #openai #gpt model due to cost. I can say with authority that the #claude models are better for me. They work the way I work, and think the way I think. I'm fighting #gpt 5.3's core training daily.

It turns out that the #copilot built into Windows knows how to create #powerautomate flows, but the one built into powerautomate itself is basically useless. I get it, these are separate tools written by different teams. Still...

#ai #agentic and #microservices systems both need instrumentation. Combine them like #rockbot, and you _really_ need good metrics to identify issues before they become real problems! blog.lhotka.net/2026/03/11/T...

To be useful, #rockbot needs other agents and #mcp servers, because it follows the principle of least privilege. Each has permission to do just what it does. #agentic #ai in action. blog.lhotka.net/2026/03/03/T...

A few of these aren't out of the oven yet, but they will be this year. Meanwhile, be sure to ask your FLGS to help you fill in any gaps in your collection.

This interview is one of my most honest and upfront. I also wax poetic a few times bc I’m old. Anyway, thank you Shingai Njeri Kagunda. Great questions!

One common challenge with #agentic systems is agent/tool discovery. To solve this, I built a registry service for #a2a, #mcp, #acp, and message-based #a2a, so virtually any agent/tool can list itself for discovery within a system. github.com/marimerllc/a...

Last night #rockbot noticed that I have some conference submissions (calls for speakers) open, so it created talk titles/abstracts for me to submit. Very thoughtful 😎

Why am I creating #rockbot? Because I want to have a personal/professional #ai bot that I can trust - that has clear security boundaries and which could be connected to my business services in addition to my personal and work emails and calendars. github.com/MarimerLLC/r...

I love how #claudecode says something will "take a day of focused work" and then plans and implements the entire feature in 30 minutes. Software development has become so much fun again!

You where you have a child give you instructions on how to make a sandwich and you literally do what they say? It is hilarious! Building an #ai bot isn't all that different, but instead of hilarious, it is frustrating.
