Gentleman Programming@G_Programming·
Nueva release de Gentle AI: v1.28.2 ya está disponible. Si usás Claude Code, OpenCode y PI con Gentle AI, este update te resuelve dos problemas reales que la comunidad venía reportando: 1. Skill Registry persistente en startup El .atl/skill-registry.md ahora se refresca automáticamente al arrancar tu agente, con cache por fingerprint. Si lo borraste sin querer, se regenera solo en el primer prompt. Funciona via hook UserPromptSubmit en Claude Code y via chat system transform hook en OpenCode. Atómico, sin tocar tu .gitignore. 2. Backups más inteligentes Los upgrade backups ahora incluyen únicamente archivos manejados por Gentle AI, no caminan el directorio entero de config de tus agentes. Además se saltean archivos no regulares (sockets Unix, FIFOs, devices, directorios). ¿Te acordás de los errores tratando de archivar ~/.pi/agent/intercom/broker.sock? Se terminaron. Otras mejoras de la 1.28: ✅ Parent-orchestrator delegation enforcement en SDD: cuando aparece complejidad (4+ archivos, multi-file writes, PR readiness, incidentes), los orquestadores delegan en vez de hacerlo monolítico. ✅ Solo-agent platforms usan reglas equivalentes de phase-boundary cuando no hay subagents nativos. ✅ Go baseline a 1.25.10, CI/release/E2E alineados. ✅ Cleanup de hooks viejos SessionStart durante uninstall. Gracias enorme a @mata-2p por el PR original que destapó este edge case y empujó el upgrade de Go. github.com/Gentleman-Prog… #AI #DeveloperTools #ClaudeCode #OpenCode #OpenSource #SoftwareArchitecture

Tengo un vídeo en el que hablo de conceptos básicos de Frontend más allá de frameworks. El event loop, conceptos de los navegadores, y en general conceptos a alto nivel que te ayudarán a desarrollar mejor (aunque utilices IA). Ahí va el link! f.mtr.cool/hhdiyszrqz

Starting a new project shouldn’t mean rebuilding your setup from scratch. Experiment: init from an existing project (local or remote) and bring over components (including customizations), theme, fonts, deps, the whole setup and file structure. Works cross-framework: start a TanStack app from an existing Vite app.

Claude te da la razón aunque estés equivocado 🤷‍♂️ Hasta que instalas LLM Council. Haces una pregunta → 5 asesores la atacan desde ángulos distintos → se revisan entre ellos → te dan un veredicto claro. Cómo funciona: 1. Haces una pregunta real (decisión, no teoría) 2. 5 perspectivas la analizan 3. Se evalúan entre ellos de forma anónima 4. Un “chairman” sintetiza veredicto + decide el siguiente paso Sigue estos 4 pasos: 1.Descarga el skill (enlace abajo) 2.Abre “Customize skills” en Claude 3.Sube SKILL.md 4.Escribe /llm-council Claude te valida. Esto te corrige.

How to design anything in Claude in 5 mins: (even if you've only ever used the basic chat) 1. Open claude .ai/design (it has its own URL). 2. Format: Wireframe, Slides, template or Freeform. 3. Sign in with a Pro or Max plan. 4. Use my full setup guide: claudedesign.free. Before you prompt, get a DESIGN .md: 1. Drop every brand asset into a Cowork folder. Prompt: "Save the design system as DESIGN .md" 2. OR steal one in 30 secs from getdesign .md (Airbnb, Ferrari, Pepsi, any brand) ✦ Then stop describing pixels. Paste this instead: "Build a pricing page. 3 tiers, monthly/annual toggle, sticky CTA on mobile. Match our homepage tone." ✦ Good prompts have goals, layout, content & constraints. It reads DESIGN .md to build the page. ✦ For pitch decks, never ask for slides directly. Generate a 30-sec animated video first, then in the same chat: "convert the video into a slide pitch deck." ✦ Iterate in two places: Structural change in chat: "Give 3 different layouts." Pixel changes in canvas. Click edit, it lights up green ✦ Always validate before you export: "List WCAG 2.1 AA violations with fixes." "Generate desktop, tablet, and mobile versions." "Suggest 2 A/B variations of the hero section." ✦ Top right → Export. In PPTX, PDF, standalone HTML, or a bundle for Claude Code format. The secret is knowing how to prompt. But to go even deeper, use my full guide: claudedesign.free. (save this if you can't design - you won't need to)

GitHub acaba de matar el vibe coding? Su nuevo repo spec-kit ya lleva 92k estrellas, y muestra hacia dónde va de verdad el desarrollo con IA. Esto es lo que hace: En vez de pedirle a tu IA "hazme una app de tareas" y rezar… ejecutas 6 comandos que convierten tu idea en una especificación estructurada que el agente puede ejecutar: /speckit.constitution → define las reglas del proyecto (calidad, testing, UX) /speckit.specify → describe QUÉ construir (no la tecnología) /speckit.clarify → la IA hace preguntas para eliminar ambigüedades /speckit.plan → ahora sí, eliges el stack /speckit.tasks → genera una lista de tareas ordenada por dependencias /speckit.implement → el agente lo construye El entregable ya no es el código. Es una especificación viva que tu IA lee, discute y ejecuta. Funciona con Claude Code, Copilot, Cursor, Codex, Gemini y 25+ agentes más. El cambio que casi nadie está viendo: "La IA escribe código" → "La IA ejecuta una especificación." El desarrollo centrado en la intención es el nuevo estándar.

Hooks te permiten ejecutar acciones automáticas en momentos específicos del ciclo del agente. Por ejemplo: - bloquear comandos peligrosos antes de que se ejecuten - correr Prettier automáticamente después de editar archivos - lanzar tests - mandar notificaciones - ejecutar scripts al finalizar tareas Y lo importante:
son deterministas. No dependen de que el modelo “se acuerde”.
Se ejecutan siempre.

Chrome just became massively more agent-friendly 🔥 Your real, signed-in browser can now be natively accessible to any coding agent. No extensions. No headless browser. No screenshots. No separate logins. Just one toggle to enable it. Check this out: developer.chrome.com/blog/chrome-de…
Peter Steinberger 🦞@steipete

New @openclaw beta is up: it comes with the new live browser control that Google added in latest Chrome! enable via chrome://inspect#remote-debugging Your clanker will know when to use what, or you can ast it. new "user" profile session is there! developer.chrome.com/blog/chrome-de…

🚨 You need to see this. @addyosmani from Google just dropped his new Agent Skills and it's incredible. It brings 19 engineering skills + 7 commands to AI coding agents, all inspired by Google best practices 🤯 AI coding agents are powerful, but left alone, they take shortcuts. They skip specs, tests, and security reviews, optimizing for "done" over "correct." Addy built this to fix that. Each skill encodes the workflows and quality gates that senior engineers actually use: spec before code, test before merge, measure before optimize. The full lifecycle is covered: → Define - refine ideas, write specs before a single line of code → Plan - decompose into small, verifiable tasks → Build - incremental implementation, context engineering, clean API design → Verify - TDD, browser testing with DevTools, systematic debugging → Review - code quality, security hardening, performance optimization → Ship - git workflow, CI/CD, ADRs, pre-launch checklists Features 7 slash commands: (/spec, /plan, /build, /test, /review, /code-simplify, /ship) that map to this lifecycle. It works with: ✦ Claude Code ✦ Cursor ✦ Antigravity ✦ ... and any agent accepting Markdown. Baking in Google-tier engineering culture (Shift Left, Chesterton's Fence, Hyrum's Law) directly into your agent's step-by-step workflow! `npx skills add addyosmani/agent-skills` Free and open-source.
