🎉 **We are repeating our First Event!** We're thrilled to announce that we will repeat the our first Claude Code Barcelona meetup! There were too many people on the waiting list, so we decided repeat it. 📅 April 22th \| Doors open at 6:00 PM\, kick off at 6:15 PM 📍 **[Codurance](https://www.google.com/search?sca_esv=b81e1b9584c528ab&sxsrf=ANbL-n7MpukpQr_6sfikIQqLIzoOVYrOxg:1776320685013&q=Codurance&si=AL3DRZGNtcdgKOqVhotcr-UG2kkYpwR2WO4qu3O00NmpwBmLnXi7y0GyPSADoBUtPRhv06cajx7_r6iMd1DRZfljen5W1KATcWl80q6B5FKtteYhjjWnc60%3D&sa=X&ved=2ahUKEwiJ1b-b3vGTAxWYUqQEHWarITEQ_coHegQINBAB)** — Carrer de Pallars 99, 4th floor, room 41, 08018 Barcelona A huge thank you to **Helena Abellán**, **Jose Enrique Rodriguez Huerta**, and their company for hosting us, thank you for responding and being organising this in a short notice 🙌 **Agenda** ➡️ 6:00 PM — Check-in 🏢 6:15 PM — Host company presentation 🚀 6:25 PM — Community kick off 🎤 6:40 PM — *Taming the Genie: What 6 months with Claude Code taught me about coding agent,* by Benjamin Tarenne (in English) 🎤 7:20 PM — *AI Mythbusters: Debunking LinkedIn BS,* by Maite Malavia (in Spanish) 🤝 8:00 PM — Networking *** **🎙️Talks** **Taming the Genie: What 6 months with Claude Code taught me about coding agent,** AI coding assistants are powerful — but like a genie, they do exactly what you ask, not what you mean. In this talk I share what I've learned from 6 months using Claude Code in real projects: the failure modes nobody talks about (context collapse, token-burning spirals, silent over-reliance), my actual setup and CLAUDE.md, and the principles I now live by. *Benjamin Tarenne, Senior Full Stack Software Engineer building products for Allianz and Claude Code Barcelona community co-organizer.* **AI Mythbusters: Debunking LinkedIn BS** From "AI is going to replace all devs", "AI already thinks" and "AI learns from your chats", to "with a RAG, AI will never hallucinate again" or "APIs are dead, long live MCPs", in this talk we'll do something highly disruptive in the tech industry: revisit some AI basic concepts. We'll go through some of the most persistent myths about artificial intelligence with no doomsaying, no hype, a hint of embarrassment in some cases, and something very old school but effective: evidence. Warning - You might leave with fewer certainties than you came in with. That's exactly the point. *Maite Malavia, Solutions Architect & AI Consultant partner at Zenital and Claude Code Barcelona community co-organizer.* *** **What to expect** This community is being built around solid engineering practices, not vibe coding. We want to explore what it really means to do agentic coding well, and how Claude Code fits into a professional engineering workflow. We have prepared some content around the basics of agentic coding and AI to get the conversation started, but we'd love to hear from you too! 👉 **Interested in presenting something?** If you have a topic, use case, or experience related to Claude Code and engineering practices, we'd love to have you on stage. Drop a comment below or reach out directly! ⚠️ **Spots are limited to 60 people**. We recommend reserving your spot as soon as possible. If you’re unable to attend, please let us know in advance so we can release your seat. Don't miss it! 🎉 \-\-\-\-\-\-\-\-\-\-\- 🎉 **¡Repetimos nuestro primer evento!** Como mucha gente se quedó en lista de espera para el primer evento, el kick.off del meetup Claude Code Barcelona, hemos encontrado venue para repetirlo el próximo miércoles 22 de abril. 📅 22 de Abril \| Apertura de puertas a las 6:00 PM\, kick off a las 6:15 PM 📍 **[Codurance](https://www.google.com/search?sca_esv=b81e1b9584c528ab&sxsrf=ANbL-n7MpukpQr_6sfikIQqLIzoOVYrOxg:1776320685013&q=Codurance&si=AL3DRZGNtcdgKOqVhotcr-UG2kkYpwR2WO4qu3O00NmpwBmLnXi7y0GyPSADoBUtPRhv06cajx7_r6iMd1DRZfljen5W1KATcWl80q6B5FKtteYhjjWnc60%3D&sa=X&ved=2ahUKEwiJ1b-b3vGTAxWYUqQEHWarITEQ_coHegQINBAB)** — Carrer de Pallars 99, 4º piso, oficina 41, 08018 Barcelona Muchas gracias a **Helena Abellán**, **Jose Enrique Rodriguez Huerta** y a **Codurance** por acogernos y organizarlo todo con tan poco tiempo de antelación!🙌 **Agenda:** ➡️ 6:00 PM — Check-in 🏢 6:15 PM — Presentación de nuestro anfitrión 🚀 6:25 PM — Presentación de la comunidad 🎤 6:40 PM — *Taming the Genie: What 6 months with Claude Code taught me about coding agent,* con Benjamin Tarenne 🎤 7:20 PM — *AI Mythbusters: Debunking LinkedIn BS,* con Maite Malavia 🤝 8:00 PM — Networking *** 🎙️ **Charlas** **Domando al genio: lo que 6 meses con Claude Code me han enseñado sobre los agentes de programación** Los asistentes de programación con IA son potentes — pero, como un genio, hacen exactamente lo que les pides, no lo que realmente quieres decir. En esta charla comparto lo que he aprendido tras 6 meses usando Claude Code en proyectos reales: los modos de fallo de los que nadie habla (colapso de contexto, espirales de consumo de tokens, dependencia silenciosa), mi configuración real y mi CLAUDE.md, y los principios por los que ahora me guío. ***Benjamin Tarenne***\*, Senior Full Stack Software Engineer desarrollando productos para Allianz y coorganizador de la comunidad Claude Code Barcelona.\* *** **Cazadores de mitos de la IA: desmontando el “humo” de LinkedIn** Desde “la IA va a reemplazar a todos los desarrolladores”, “la IA ya piensa” o “la IA aprende de tus chats”, hasta “con un RAG la IA dejará de alucinar” o “las APIs han muerto, larga vida a los MCPs”, en esta charla haremos algo altamente disruptivo en la industria tecnológica: revisar algunos conceptos básicos de la IA. Recorreremos algunos de los mitos más persistentes sobre la inteligencia artificial sin catastrofismo, sin hype, con un toque de VA en algunos casos y algo muy old school pero efectivo: evidencia. ⚠️ Advertencia: puede que salgas con menos certezas de las que tenías al entrar. Ese es precisamente el objetivo. ***Maite Malavia***\*, Solutions Architect & AI Consultant partner en Zenital y coorganizadora de la comunidad Claude Code Barcelona.\* *** **¿Qué esperamos?** Esta comunidad quiere construirse alrededor de buenas prácticas de ingeniería, no del vibe coding. Queremos explorar qué significa realmente hacer agentic coding bien, y cómo Claude Code encaja en un flujo de trabajo de ingeniería profesional. Hemos preparado contenido sobre los fundamentos del agentic coding y la IA para arrancar la conversación. ¡Pero nos encantaría contar también contigo! 👉 **¿Te interesa presentar algo?** Si tienes un tema, caso de uso o experiencia relacionada con Claude Code y buenas prácticas de ingeniería, ¡nos encantaría tenerte como ponente! Deja un comentario abajo o contáctanos directamente. ⚠️ **El aforo es de 60 plazas.** Te recomendamos reservar la tuya cuanto antes. Si finalmente no puedes asistir, por favor avísanos con antelación para liberar tu plaza. ¡No te lo pierdas! 🎉

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
