It is becoming f*cking dangerous: I launched a full-fledged autonomous crawler that parses any website with ZERO LINES OF CODE Forget about Python, terminals, CSS selectors, and constant manual copy-pasting You can set up a seamless No-Code integration just once, where Claude becomes the brain of your automatic data collector, and the results automatically flow straight into your spreadsheets In this setup, a No-Code service accesses the website and grabs the raw content, while Claude instantly cleans out the noise, extracts the key insights, and organizes everything neatly How to set this up: 1. Pick a No-Code service: Sign up for makecom, zapiercom, or install the bardeenai extension (all of them offer free tiers) 2. Set up the Launch: Specify how often the crawler should run (for example, Every day at 9:00 AM or At the click of a button) and feed it the target URLs 3. Connect the Claude module: Add an AI step to your scenario and give Claude a clear instruction: "Analyze the provided page text. Extract product names, prices, discounts, and seller contact details. Return the data as a clean, structured list" 4. Choose where to save the results: Connect the final step (for instance, Google Sheets or Notion) Quick 5-minute setup, full 24/7 autonomy, and zero headache with code maintenance. Essentially, with just a few clicks you are creating your own smart AI agent that quietly handles the routine work while you focus on real tasks Bookmark this for later

It is becoming f*cking dangerous: I don't understand why everyone still isn't doing this, thanks to this I reached an income of $12,000 as early as 3 months ago Andrej Karpathy, co-founder of OpenAI, shared a straightforward concept that blew up with over 23 million views: stop relying on AI strictly for coding and start using it to construct your own personal knowledge engine Point Claude Code to a folder, toss in raw materials (whether it's an article, a video transcript, or a PDF) and Claude processes everything, links relevant topics together, and organizes it into a self-updating wiki of your personal knowledge. It acts like compound interest: the more information you add, the more capable it becomes Here is the exact breakdown: Set up Obsidian, create a fresh vault, and open it using Claude Code Supply Karpathy's wiki layout prompt and instruct Claude to build the architecture Claude automatically sets up three components: a ⁠raw⁠ directory for source files, a ⁠wiki⁠ directory for processed pages, and a ⁠CLAUDE.md⁠ control file to run the system Dump any document into the ⁠raw⁠ folder and run "ingest this" Query your entire knowledge repository at any time, indefinitely It takes just five minutes to configure, eliminating the need to ever start a conversation with a completely blank context window again Check the link below for the complete step-by-step walkthrough on setting up Claude with Obsidian Bookmark this post for later

Andrej Karpathy just explained the 5 shifts turning LLMs into agentic systems. 00:00 - Memory turns chat into personal AI 06:41 - Multimodal AI reads the world 16:58 - Thinking models solve harder tasks 24:51 - Search makes LLMs live 30:58 - Tools turn LLMs into workers Most people are still treating LLMs like chatbots. Karpathy is showing the full stack: Memory → Vision → Reasoning → Search → Tools Prompting is the old workflow. Agentic systems are the new one. This 40-minute talk is worth more than most paid AI agent courses. Bookmark and watch it before everyone catches up. Then read how to turn LLMs into self-improving agent loops below

your agent was never just a loop it is three contracts built around one model loop vs graph vs harness engineering the loop is a contract with time the graph is a contract with state the harness is a contract with reality loop engineering defines the temporal contract how many attempts are available how much budget one run can consume what qualifies as real progress which condition ends the execution when the agent continues trying after the evidence has stopped changing the temporal contract is broken make every attempt durable limited and measurable → github.com/temporalio/tempor… graph engineering defines the state contract which transitions are permitted which branches can execute in parallel where the system can safely resume what must be present before the next node begins when the agent reaches a valid node through an invalid state the state contract is broken make every transition visible and explicit → github.com/langchain-ai/lang… inspect the topology separately from the model → github.com/networkx/networkx harness engineering defines the execution contract which tools are available which secrets can be accessed where generated code is executed which actions need approval when the correct transition produces the wrong external effect the execution contract is broken isolate and contain every tool call → github.com/e2b-dev/E2B validate quality before deployment → github.com/openai/evals trace the contract through every system boundary → github.com/open-telemetry/op… bound the time validate the state contain the effect the model creates a proposal the system enforces the contracts bookmark this before your next agent rewrite then read the article below

How to set up your Claude code project? A proper Claude Code project lives inside a .𝗰𝗹𝗮𝘂𝗱𝗲/ folder. - Start with 𝗖𝗟𝗔𝗨𝗗𝗘.𝗺𝗱 as Claude's instruction manual. - Split it into a 𝗿𝘂𝗹𝗲𝘀/ folder as it grows. - Add 𝗰𝗼𝗺𝗺𝗮𝗻𝗱𝘀/ for repeatable workflows - 𝘀𝗸𝗶𝗹𝗹𝘀/ for context-triggered automation - and 𝗮𝗴𝗲𝗻𝘁𝘀/ for isolated subagents. - Lock down permissions in 𝘀𝗲𝘁𝘁𝗶𝗻𝗴𝘀.𝗷𝘀𝗼𝗻. There are two .𝗰𝗹𝗮𝘂𝗱𝗲/ folders: - one committed with your repo - one global at ~/.𝗰𝗹𝗮𝘂𝗱𝗲/ for personal preferences and auto-memory across projects. The .𝗰𝗹𝗮𝘂𝗱𝗲/ folder is infrastructure. Treat it like one. The article below was written by my co-founder some time back, and it is still very much relevant. It is a complete guide to 𝗖𝗟𝗔𝗨𝗗𝗘.𝗺𝗱, custom commands, skills, agents, and permissions, along with how to set them up properly. Read it below.

This paper is f*cking brilliant A computer science paper replaces Mixture-of-Agents with Graph-of-Agents for multi-LLM collaboration The result: structured node sampling, directed message passing, and graph pooling deliver state-of-the-art benchmark scores using only 3 active agents instead of 6 The crazy part is how graph engineering cuts multi-agent inference cost while improving decision accuracy Relevant model nodes are sampled via domain cards, directed edges pass responses from expert to generalist models, and graph pooling aggregates final consensus Most multi-agent architectures blindly feed every query to every model in the pool This framework converts multi-agent collaboration into an optimized communication graph Read the complete paper + article below Bookmark it for future reference

De prompt engineering → context engineering → harness engineering → loop engineering → graph engineering: La lista no deja de crecer, y cada nuevo término suele tratarse como si sustituyera al anterior. Pero la realidad es otra: cada capa envuelve a la anterior. La forma más sencilla de diferenciarlas es preguntarse cuál es su unidad de trabajo. Prompt engineering es el mensaje El modelo no recuerda nada antes de esa llamada, así que el prompt tiene que contener todo lo necesario: el rol, el contexto, las instrucciones, algunos ejemplos y el formato de salida. Si el resultado no es el esperado, la clave está en descubrir qué elemento falta o falla, no en reescribir todo el prompt una y otra vez. La unidad de trabajo es una única entrada. Context engineering es la memoria A lo largo de varios pasos, la ventana de contexto es limitada, pero la información disponible no lo es. Por eso hace falta un proceso de selección. Ese proceso consiste en conservar lo importante, resumir lo útil pero voluminoso y descartar el resto. Un buen contexto no consiste en meter más información, sino en saber qué eliminar. La unidad de trabajo es lo que permanece dentro de la ventana de contexto. Harness engineering es la máquina Por sí solo, un modelo solo genera texto. El harness se encarga de recopilar la información necesaria, ejecutar el modelo, llamar a herramientas o subagentes y verificar el resultado mediante pruebas o un evaluador. Ese paso de verificación es, en gran medida, lo que diferencia una simple llamada a una API de un agente de IA. La unidad de trabajo es una ejecución completa de la máquina. Loop engineering es la ejecución iterativa Una sola ejecución rara vez resuelve todo el problema. Hace falta un mecanismo que decida si la máquina debe volver a ejecutarse. Para ello se necesita un objetivo definido desde el principio, límites como un número máximo de iteraciones o un presupuesto de coste, y un criterio automático que determine cuándo la tarea realmente ha terminado. Que un agente deje de pedir herramientas no significa que haya completado el trabajo; solo significa que ha terminado ese turno. La unidad de trabajo es toda la ejecución del ciclo. Graph engineering es la coordinación Cuando varios bucles tienen que trabajar juntos, necesitas definir qué se ejecuta, cuándo se ejecuta, qué puede hacerse en paralelo y qué componentes supervisan a otros. Los nodos realizan el trabajo, las conexiones (edges) deciden qué ocurre después y el estado compartido fluye entre ellos. De hecho, un único bucle no deja de ser un grafo de un solo nodo con una conexión que apunta de vuelta a sí mismo. Por eso los grafos organizan los bucles, no los sustituyen. La unidad de trabajo es el proceso completo. La relación entre todas estas capas es sencilla: El prompt y el contexto viven dentro de la fase de recopilación del harness. El harness ejecuta una pasada completa. El loop decide si esa pasada debe repetirse. El graph decide qué bucles se ejecutan y cómo se coordinan entre sí. Cuanto más amplías la perspectiva, mayor es la unidad de trabajo. Cuanto más profundizas, vuelves al prompt. Y eso también indica dónde depurar un problema: identifica qué capa ha fallado según su unidad de trabajo y corrige esa capa. El prompt es la parte más fácil de modificar, por eso suele recibir la culpa de errores que, en realidad, se originan tres niveles más arriba. En el articulo de abajo, se explica que es el graph engineering, donde explica la idea principal, cómo empezar, cómo gestionar el estado compartido, cómo crear un enrutamiento fiable y cuándo usar un grafo realmente merece la pena.

Esto es una auténtica joya. Hace cinco semanas, Andrej Karpathy se unió a Anthropic. Dos ingenieros senior de Anthropic llevaron el enfoque de Karpathy un paso más allá con el concepto de Graph Engineering. Los sistemas agénticos mejoran de verdad cuando conectas los agentes en forma de grafo. Lo integré en mi configuración y la primera respuesta ya fue completamente distinta. No fue una mejora pequeña. Fue un cambio total. Claude dejó de dar respuestas genéricas y empezó a trabajar exactamente como yo quería. Guárdalo antes de que se pierda en tu feed.
