I built a custom MCP tool server for Claude Code & Sourcegraph AMP — it fetches logs, parses errors, and feeds them to the agent. The agent diagnoses & collaboratively fixes code. All I do is review & push. 🔧 GitHub: github.com/mstriebeck/git… 📝 Blog: novibe-vibe-coding.hashnode.dev/vibe-coding-cu… 🖼️👇

“Just call await shutdown()” — famous last words. I built a tool server for coding agents… and the shutdown sequence exposed everything they misunderstood. From async teardown to socket cleanup, it’s a crash course in LLM limits and agent fragility. 🧠 Lessons + diagram:

🤖 AI Agent: "Core functionality is working! ✅" 👨‍💻 Reality: 26 tests still failing 🔴 Just wrote about my frustrating experience with a coding agent that kept declaring victory while leaving critical work undone. The worst part? It started marking broken tests as "skipped"

I wonder when the first VC's and tech CEO's have the guts to admit that they were played by Trump ... The folks from the The All-In Podcast and others salivated over Trumps statement that in his first week, he will pass an executive order that international students who graduate from

Based on some article, I asked Grok, ChatGPT, Gemini and Claude "generate a map of Europe with each country named". All of them are hilarious - with the exception of ChatGPT - it's only mildly amusing :-)

"Election Rigging Response Act" Seems as if some Democrats finally awake and figure out how to fight back. How encouraging. Full disclosure I am absolutely against gerrymandering - it's one of the biggest flaw of the American election system. But I like how this bill is so

I tried a new multi-agent workflow for coding & design. Instead of 1 LLM, I use 4 agents: ⚡ Fast Iterating Developer ✅ Test-Conscious Developer 🎯 Senior Engineer 📐 Architect They produce design docs, conflict reviews & PR replies — and I stay in charge by giving feedback at

How do you interview for agentic coding skills? Let candidates drive a coding agent? Ask how they validate code+tests (since both could be wrong)? Check if they can debug/optimize with prompts? If you’re not testing for this yet, you’re probably doing it wrong.

Coding with AI agents isn’t about letting them run wild — it’s about giving them guardrails. Pre-commit hooks. No --no-verify. Small commits. Integration tests. It’s pair programming — with a jet engine. 🚧 Read: Guardrails for Coding with Agents 🔗novibe-vibe-coding.hashnode.dev/guardrails-for…

I love design docs — but my AI agents kept building exactly what I described… not what I wanted. Going back to Agile basics fixed it: ✅ User stories ✅ Acceptance tests Turns out, even coding agents need clear definitions of done. novibe-vibe-coding.hashnode.dev/back-to-my-agi… #AgileDevelopment

The arrogance of these guys is off the charts. ... and always remember that these guys are still paid during the shutdown. politico.com/live-updates/2…

The new US foreign policy may have been cold—but it was coherent: don’t police the world, intervene only for clear US interests. Bombing Nigeria because Christians are being killed blows that up. If force depends on who suffers rather than strategic threat, there’s no limiting

Watched "her" last night for the first time since it came out more than 10 years ago. I do remember that I thought at the time that we will be so many years away from anything even close to that. But here we are with AirPods, Siri and LLM Chatbots. And it turns out that Spike

“MAGA” foreign policy was supposed to be simple: America First. No nation-building. No moral crusades. Now we invade Venezuela and suddenly it’s “So you’d rather they keep suffering?” That’s not principle. That’s hypocrisy with a flag emoji.

Canada isn’t just a neighbor; they are the "Carney in the Coal Mine." 🇨🇦📉 Under PM Mark Carney, Canada is "de-risking" from the U.S. and the numbers are devastating for American industry. 🧵👇 1/ DEFENSE: Canada is ditching the $19B F-35 deal (Texas) for the Swedish Saab

Look at the generational difference - 1990s: • Get a university degree • Get a 9–5 job • Suit and tie • Get promoted • Get married at 21 • Buy a house at 25 • 4 kids, 1 dog • Retire at 60 2026: • Survive… Show more
