This is the most complete Claude Code setup that exists right now.
27 agents. 64 skills. 33 commands. All open source.

The Anthropic hackathon winner open-sourced his entire system, refined over 10 months of building real products.

What's inside:
→ 27 agents (plan, review, fix builds, security audits)
→ 64 skills (TDD, token optimization, memory persistence)
→ 33 commands (/plan, /tdd, /security-scan, /refactor-clean)
→ AgentShield: 1,282 security tests, 98% coverage

60% documented cost reduction.

Works on Claude Code, Cursor, OpenCode, Codex CLI. 100% open source.

@dobleio @XMihura Esto es interesante. Has hecho alguna prueba con la ia usando este formato para documentar ?

My 'grill-me' skill went viral. mattpocock/skills is up to 9K stars. Quote tweets of it are doing numbers.

It's the most useful skill I've written, and I use it even outside of coding:

[Uncle Bob Martin @unclebobmartin]

In the last three days I have:
1. Designed and implemented a complete JVM language that Codex believes (whatever that means) would be ideal for AIs to use regardless of what humans think about it. It compiles down to JVM bytecode.

2. Designed and build, from scratch, a wiki with it's own internal web server and fully described by Gherkin style acceptance tests.

3. Made significant updates to the computer strategy of the Empire game.

4. Produce the crap4java and mutate4java tools that I used to help build the wiki.

5. Conceived of and implemented the differential mutation strategy used in both my clojure and Java mutation tools.

And for every one of those projects I implemented a strict TDD, ATDD, Crap, and Mutate workflow that forced coverage into the high 90s, kept Crap below 8, and split any files with more than 50 mutation sites.

My poor laptop had all 16 (8 hyperthreaded) cores burning at 100%. The fan was raging the whole time. I was hopping from window to window overseeing the entire campaign. It was exhausting!

Did that workflow slow the process down? Probably. Probably a lot. On the other hand all these projects maintained rigorous semantic stability, with all unit tests, and acceptance tests passing.

I never ran the wiki until it was done. It worked first time. I never compiled a program with AIR-J until it was done. It worked first time. No bugs have been introduced into the Empire game (so far).

And that, boys and girls, is a freaking miracle.

[Uncle Bob Martin @unclebobmartin]

https://t.co/f5MGDf8qXH is a nice little architecture viewer written in clojure, for clojure projects. But if you point clause or codex to it I bet you could ask it to write you one for your favorite platform.

I've found it really useful for looking at the structure of the system, and for detecting nasty little dependency cycles and removing them.

Como dev, siempre asumí que el pensamiento se empaqueta en Sujeto-Verbo-Objeto: "El programador compila el código".
¿Y si esa tríada no es universal?
Descubrir lenguas ergativas como el euskera me rompió el esquema.
¿Y si el lenguaje moldea cómo pensamos? (1/3)

[Joaquin Jose del Cerro Murciano @jjdelcerro]

Los agentes de IA actuales son reactivos: solo actúan cuando les preguntas. ¿Pero qué pasa cuando necesitas que reaccionen automáticamente a un cambio en el entorno? Un servidor que cae, una anomalía en los datos… Esperar a la pregunta humana llega tarde.

[Joaquin Jose del Cerro Murciano @jjdelcerro]

Mi LLM se volvió loco: leía las notas del proyecto y, sin que yo dijera nada, empezaba a editar https://t.co/ErsTDXGSud como si le fuera la vida en ello.
Tres veces seguidas. Discusión, disculpa… y vuelta a editar.
Bienvenidos al “sesgo agéntico” de 2025. 🧵

[Alejandro Vidal @dobleio]

Agentic Engineering no es vibe coding con esteroides - es un problema de alineamiento.

Hoy en @HackNightVLC sobre primeros principios para escalar software con agentes: feedback loops, reward hacking, hawk agents y el tiempo humano como recurso escaso.

Gracias a @flywire!

I encountered a delightful little astrodynamics proof last week when an astronaut casually stated it as a fact, and when I looked skeptical, he just smiled and said, "Check it yourself."

Here's the statement:

"It takes 2 hours to orbit at the surface of any object made of rock"

So here's a story of, by far, the weirdest bug I've encountered in my CS career.

Along with @maciejwolczyk we've been training a neural network that learns how to play NetHack, an old roguelike game, that looks like in the screenshot. Recenlty, something unexpected happened.
