@twostraws Thanks for sharing this!

Qq: does it also support markdown tables?

[Mary Baptista Martinez @MaryLBMC]

@fidjissimo Thank you for your openness with sharing your story. Health is somethingwe cannot ignore.

My partner also lives with a chronic disease and it is not easy. One thing that has made a huge difference in her health is working with a naturopathic doctor. I highly recommend it!

@adamlyttleapps Love this! The hard part is getting everything to the finish line

This is a new paradigm for interacting with Claude that is significantly more "inline" with all the other human activity org-wide. Once you do all of the under the hood engineering work to make this "just work" (e.g. across tools, integrations, compute environments, memory, security, etc.), Claude basically joins the team in a seamless way - you can talk to it as you would talk to a person and it can help with a very large variety of workloads.

Imo this is the 3rd major redesign of LLM UIUX. The first paradigm was that the LLM is a website you go to, the second was that it is an app you download to your computer. This third one is that it is a self-contained, persistent, asynchronous entity with org-wide tools and context, working alongside teams of humans. It really takes a while to wrap your head around it, but it works and it is awesome.

On Claude Team and Claude Enterprise, you can now use Claude Code to deploy HTML sites and share these with your teammates!

This has changed how we work internally. Artifacts is great format for communicating architecture changes, data analyses, and new prototypes.

@om_patel5 Source?

🚨How do you index the entire Linux kernel (28M lines of code) for an AI agent in 3 minutes?

You stop letting the agent read files one by one.

There is a fascinating new open-source release called codebase-memory-mcp.

It's a code intelligence engine that swaps traditional file-searching for high-speed AST knowledge graphs.

What makes this project stand out is the research behind it.

Evaluated across 31 real-world repositories (detailed in arXiv:2603.27277), the architectural shift yields massive efficiency gains:
→ 99% reduction in tokens for structural queries
→ 83% answer quality across complex tasks
→ 2.1x fewer tool calls required

It maps functions, classes, HTTP routes, and cross-service links into a graph. When the agent needs context, it queries the graph directly.

Security is prioritized too: everything happens 100% locally on your machine via a single static binary.

It runs entirely locally.

No Docker, no Ollama, no API keys.

You download the binary, restart your agent, and it just works.

Are we one good index away from cutting AI dev costs to zero?

Claude Mythos is Insane!

❤️‍🔥Just recorded a 12-min tutorial on how to build animated, award-Winning websites with Claude Fable 5!

Quite strange: @github just logged out all active sessions for all its users.

Steps to become a senior programmer:

1. Install my /teach skill

npx skills add mattpocock/skills --skill teach

2. Create a new working directory on your laptop

mkdir junior-to-senior
cd junior-to-senior

3. Kick off your coding agent in the directory

claude

4. Copy this prompt

/teach me how to be a great strategic programmer. My opinion is that AI is eating 'tactical, on-the-ground' programming. The day-to-day work of a developer involves not only coding, but also planning, QA, codebase design, and much more. I'm interested in learning the strategic skills - that, in a previous era, would take me from junior to senior - but in this era are table stakes.

5. Paste it into the coding agent

Below is an example of what the first output will look like. I used Opus 4.8, medium effort.

6. Continue working with the agent until you're a senior

This is a super exciting release - Claude Fable 5 is the same underlying model as Mythos but with added safeguards. The benchmarks are great and it's SOTA on everything by a margin but I'll add that *qualitatively* also, this is a major-version-bump-deserving step change forward (imo of the same order as Claude 4.5 was in November), peaking especially for long problem-solving sessions on very difficult problems. You can give it a lot more ambitious tasks than what you're used to, the model "gets it" and it will just go, and it's never felt this tempting to stop looking at the code at all (but don't do this in prod!). The model still has quirks that people will run into and the safeguards are configured to be a little too trigger happy for launch, which can hopefully be tuned over time.

I feel a lot of things changing as working software increasingly comes out on a tap. The Jevon's paradox kicks in and I feel my own demand for software growing substantially. You can ask for anything - explainers, visualizers, dashboards, bespoke single-use apps (e.g. a full wandb that is hyper-specific just for your project), you can 10X your test suite, auto-optimize code, run giant research projects with custom HTML for the results, anything! "Free your mind" (Matrix ref). Really looking forward to all the things people build!

One of my personal favorite features announced at WWDC will I suspect be a sleeper hit: container machines, allowing your Mac to run a lightweight, persistent Linux environment with your home directory and repos automatically mounted: https://t.co/dOBdfOOVxC

Claude Fable 5 changed how we work on the Claude Code team day to day.

We used to verify that Claude did the work right. Now we verify that it's doing the right work.

Here’s the 3 biggest changes:

[Boris Cherny @bcherny]

We talk a lot about how important it is to set up self-verification loops. Especially in the age of powerful models that can run for long periods of time, self-verification is a key ingredient that enables the model to run for much longer, delivering a result that is closer to what you intended, so you can do more without having to constantly check in on Claude as it works.

@delba_oliveira gives a great breakdown of what that looks like and why it matters

[Peter Steinberger 🦞 @steipete]

When you build native apps, codex can drive macOS Instruments app fully via the command line. Doesn't need a skill or anything, world knowledge is enough. Simply ask to profile via Instruments Time Profiler.

Published a new blog post about SwiftUI performance & tools we’re using at Airbnb to improve performance at scale https://t.co/tzhLEYd2gZ

[Brian Chesky @bchesky]

Thanks for all the feedback on our design work in the Summer Release. Here’s a little preview of everything we worked on for our new design system—new font, navigation, layout system, colors, cards, and of course, icons. Much more to come…
