If you saw my Agent SDK workshop and want to try getting hands-on, Modal just put out a great example of using the Agent SDK to make a Slack bot!
Fun new @modal demo! Create Slack GIFs with @claudeai Agent SDK running in a cloud Sandbox, triggered directly from Slack, with persistent multiplayer sessions. The hardest part? Keeping it secure.

I did a 2 hour workshop on the Claude Agent SDK at AI engineer! We are still so early to agents, I hope this is useful if you’re thinking of making one.
🆕 Claude Agent SDK [Full Workshop] https://t.co/xHeuWPuIk7 For our first big drop of the year, excited to bring you @trq212's full 2 hour workshop covering all of @AnthropicAI's agentic SDK (formerly known as Claude Code SDK). By far the most popular workshop of AIE CODE!

The more I build with Claude Agent SDK, one thing is very clear: Claude Code is just scratching the surface. Agent SDK is a beast for building new agentic experiences. This weekend, I built a futuristic agent orchestrator with it. Productivity level of coding agents are 🤯.

Finally moving off the personal Claude Code subscription and having Sentry pick up the tab so I can swap to Opus 💀

This is a good analogy. I've been working with Claude Code with Opus 4.5 for the past weeks, & I confidently say that it has achieved AGI level in coding! It is indeed a watershed moment we've been waiting for! It will continue to get exponentially better in a self-improving way!
Claude Code with Opus 4.5 is a watershed moment, moving software creation from an artisanal, craftsman activity to a true industrial process. It’s the Gutenberg press. The sewing machine. The photo camera.

Claude Code has 3 permission tiers and most people use zero of them: "allow" - Auto-approve the routine stuff "ask" - Confirm the risky stuff "deny" - Block the dangerous stuff Configure once. Never click "allow" on npm test again. Your flow state will thank you.

I'm not joking and this isn't funny. We have been trying to compile a C++ program at Bloomberg since last year. There are various options, not every struct is aligned... I gave Claude Code the source code and input, it generated the expected output in an hour.

Becoming a user of Claude Code changed the way I do my job. Then I was lucky enough to join the Claude Code team. It had an even bigger impact on my work. Being surrounded by smart, AGI pilled folks changes the way you see the world. It's hard to imagine what the next year will

If you started using Claude Code over the holidays, you might be curious about how AI actually works, the benefits and risks, and where it's headed. Here are some of my favorite papers on alignment, interpretability, and societal impacts 🧵

A few of you asked how to disable auto-generated terminal titles in Claude Code CLAUDE_CODE_DISABLE_TERMINAL_TITLE=1 claude You can also add that env var to the “env” section of your settings.json https://t.co/QBIBwnmV8B

Configure Claude Code with global and project-level settings, and environment variables.

@martin_casado @williamevanl Today I handed Claude a document that I've been growing for...years on building an orchestrator/distributed runtime that I had only purely theorized possible. One we've been working towards. It would have taken me probably months to code by hand. Building on 5 years of work and

Fiona Fung currently supports the Claude Code team at Anthropic and was previously a Senior Director at Meta. She grew quickly through the ranks at Microsoft and Meta before joining Anthropic. I interviewed her about what she learned along the way. We discussed: • When to trade

The more I fuck around with Claude Code, the more I feel like 2026 is the tipping point for how we interact with computers. Will never be the same again. All of this shit is becoming StarCraft for the next little bit.
I'm Boris and I created Claude Code. Lots of people have asked how I use Claude Code, so I wanted to show off my setup a bit. My setup might be surprisingly vanilla! Claude Code works great out of the box, so I personally don't customize it much. There is no one correct way to

Great way to use Claude Code
Claude just paid for itself (x2)! I hate (HATE) fighting with customer service. So today I thought... can Claude Code do it for me? Last month, Claude Code for Chrome was released. It's really easily to use. 1. Install the Claude extension in Chrome 2. Launch Claude Code with
