Hiya friends,
If you've been anywhere near dev Twitter this month, you've seen the lobster. OpenClaw is an open source personal AI agent that runs locally, connects to your chat apps, and does things on your behalf. A few weeks back I shared my conversation with Peter Steinberger, the creator. Since then, the ecosystem has exploded. ZeroClaw rewrote the whole thing in Rust (8MB idle vs 1.5GB). ClawHub hosts 5,700+ community skills. Agents can hold wallets and make payments. And as of yesterday, Peter is joining OpenAI. OpenClaw moves to a foundation. The lobster just got a bigger tank.
With that kind of momentum, the ecosystem is testing its own boundaries. An OpenClaw bot submitted a PR to matplotlib this week, got rejected, and published a blog post attacking the maintainer who said no. While agentic AI moves at breakneck speed, I appreciate GitHub shipping the fundamentals that keep us grounded.
🚢 What Shipped
Claude and Codex Coding Agents in Public Preview GitHub added support for Anthropic's Claude and OpenAI's Codex as coding agents. If you've got Copilot Pro+ or Copilot Enterprise, you can now run multiple specialized agents directly inside GitHub, GitHub Mobile, and VS Code.
This matters because it breaks the single-agent bottleneck. Instead of one grinding through a problem, you spin up the right agent for the task. Need Claude for architecture? Codex for refactoring? Use both. You're no longer locked into one model or one way of thinking about the problem.
PR "Files Changed" Performance Overhaul Remember when the new Files Changed experience rolled out as default? Here's what got faster since then. The "Files changed" tab on pull requests got a real performance pass. Diffs now respond up to 67% faster for clicks, typing, and scrolling on large PRs.
The bigger fix: CODEOWNERS validation was missing from the new Files Changed experience. Required reviewers are now correctly surfaced before merge. Also fixed: tab switching dropped from 10+ seconds to a few seconds on large PRs, mobile layout cleaned up, and sticky headers actually stick now.
Stacked Diffs (Coming Soon) Also coming to GitHub: stacked diffs. Jared Palmer announced Feb 6 that early design partners will get alpha access starting in March. This is the feature devs have been asking for—create, review, and merge dependent PRs as clean layers instead of one massive diff. The team had to migrate GitHub to use git reftables to make restacking efficient. It's a big infrastructure lift, but it's happening

🎧 What I'm Watching
The Night Manager (new season). Non tech but so great. And they filmed the new season in Colombia. There's something about watching a show set in places you've actually been—you catch details no one else does, recognize the energy of a city in the cinematography. The end of this season had me 😩🤬.
🔧 What I'm Using
Zo Computer as my personal AI server. This is how I run my OpenClaw, ZeroClaw, and other personal agents. It's become my baseline for everything. The CLI is snappy, the permission model actually makes sense, and I can switch AI models on a whim without leaving the terminal. No vendor lock-in. Your files stay yours. You can use Opus, Kimi, or whatever model fits the task. A generous free tier exists, so you can start without paying. If you're building with AI and tired of scattered SaaS tools, it's worth a look.

✨ This Week
Presidents Day means a free Monday for most of the US, but not for me. I'll be heads-down on a special demo that I'm very much not allowed to talk about yet. (But follow GitHub's socials. You'll know when it ships. 😉)
That's the week. Agentic AI's moving fast. GitHub's being intentional. Both matter.
Fundamentals first. Always.
With gratitude, I'll see you next week,
Andrea
