8 Agent Skills and my first MCP server published to npm

🇪🇸 Leer este post en Español I spent months watching my agent re-solve the exact same problems, over and over, because I never sat down and wrote them up once so anyone else could reuse them. That's the kind of technical debt nobody ever puts on a roadmap. So I published alpha-skills : eight installable Agent Skills and my first MCP server on npm . Where the published skills live The installable catalog lives in skills/ , split into three categories: external/ for third-party APIs, local/ for homelab and workflows, and general/ for cross-project utilities. All three are public: one skill in external/ , one in local/ , and six in general/ . local/ describes the use case. skills/ ├── external/ │ └── nextdns-api/SKILL.md ├── local/ │ └── progressive-search/SKILL.md └── general/ ├── agent-context-generator/SKILL.md ├── nestjs-iam-patterns/SKILL.md ├── nestjs-advanced-patterns/SKILL.md ├── nestjs-graphql/SKILL.md ├── tuning-claude-code/SKILL.md └── obsidian-second-brain/SKILL.md <DIAGRAM 02: 02-public-skills-structure-en.png> The eight skills Three categories: external/ for third-party services, local/ for homelab infrastructure and personal workflows, general/ for cross-cutting utilities that don't depend on any one service.
