What versioned schemas mean in practice, why take them seriously in a local CLI, how events cross the boundary and the door left open for the CLI to become a service.Fri, 17 Jul 2026 00:00:00 GMThttps://andrespineli.dev/blog/pt/rpc-versioned-schemas/https://andrespineli.dev/blog/pt/rpc-versioned-schemas/Dentro do DevStation, a interface e o engine conversam por JSON-RPC com contratos versionados, como dois sistemas independentes. O que são schemas versionados na prática, por que levar isso a sério num CLI local, como eventos atravessam a fronteira e a porta que fica aberta para o CLI virar serviço.Fri, 17 Jul 2026 00:00:00 GMThttps://andrespineli.dev/blog/en/harness-homogeneous-architecture/https://andrespineli.dev/blog/en/harness-homogeneous-architecture/Two projects, two stacks, the same low-level design, with agents writing most of the code. What abstract skills and concrete capabilities actually package, where the harness tool comes in, and why my bet is that this kind of standardization should emerge from platform teams.Sun, 12 Jul 2026 00:00:00 GMThttps://andrespineli.dev/blog/pt/harness-homogeneous-architecture/https://andrespineli.dev/blog/pt/harness-homogeneous-architecture/Dois projetos, duas stacks, o mesmo low-level design, com agentes escrevendo a maior parte do código. O que skills abstratas e capabilities concretas empacotam de fato, onde entra a ferramenta de harness, e por que minha aposta é que esse tipo de padronização deve emergir de times de plataforma.Sun, 12 Jul 2026 00:00:00 GMThttps://andrespineli.dev/blog/en/testing-with-mcp/https://andrespineli.dev/blog/en/testing-with-mcp/The end-to-end suite exercises a real Proxmox node (provision, install, uninstall, destroy), and an agent drives that cycle over MCP. Notes on the regression mocks would have missed, the cross-OS Windows validation, and test discipline with AI.Sat, 04 Jul 2026 00:00:00 GMThttps://andrespineli.dev/blog/pt/testing-with-mcp/https://andrespineli.dev/blog/pt/testing-with-mcp/A suíte e2e exercita um node Proxmox de verdade (provisiona, instala, desinstala e destrói), e um agente dirige esse ciclo pelo MCP.

Why this set, which can sound like overengineering in a CLI, was a deliberate bet on this project, what it has paid for so far and what is still a hypothesis.Sat, 27 Jun 2026 00:00:00 GMThttps://andrespineli.dev/blog/pt/designed-for-extensibility/https://andrespineli.dev/blog/pt/designed-for-extensibility/Hexagonal, DDD tático, CQRS, eventos internos e contratos JSON-RPC. Por que esse conjunto, que pode soar como overengineering num CLI, foi uma aposta consciente neste projeto, o que ele já pagou e o que ainda é hipótese.Sat, 27 Jun 2026 00:00:00 GMThttps://andrespineli.dev/blog/en/why-devstation/https://andrespineli.dev/blog/en/why-devstation/A personal origin story: from an AMD Geode running BrazilFW that bonded two home internet links, and a Pentium 4 game server, to a single self-contained CLI that describes a homelab once and rebuilds it on demand.Sat, 20 Jun 2026 00:00:00 GMThttps://andrespineli.dev/blog/pt/why-devstation/https://andrespineli.dev/blog/pt/why-devstation/Uma história de origem, em primeira pessoa: de um AMD Geode rodando BrazilFW que unia dois links de internet caseiros, e um servidor de jogo em Pentium 4, até um CLI único e autossuficiente que descreve o homelab uma vez e o reconstrói sob demanda.Sat, 20 Jun 2026 00:00:00 GMT
