The tools provide accurate, version-matched knowledge of the SelectPdf .NET library, including real API signatures and working code samples in C# and VB.NET. The skills are available as plugins for Claude Code, Cursor, GitHub Copilot, and Codex, and are designed to automatically activate when working with PDFs in .NET projects.", "body_md": "AI coding assistants are great at .NET boilerplate, but ask one to generate PDF code and it will happily invent a method that doesn't exist, or reach for a commercial feature while claiming it's in the free edition. The model is guessing from training data.\n\n[SelectPdf AI Tools](https://github.com/selectpdf/ai-tools) fixes that. It's a free, open-source (MIT) set of **Agent Skills** that give your assistant accurate, version-matched knowledge of the [SelectPdf .NET library](https://selectpdf.com/pdf-library-for-net/) — real API signatures, working code, and the gotchas that matter.\n\nA single Claude Code plugin with two skills:\n\n`selectpdf-lib-net`\n\n`selectpdf-lib-htmltopdf-net`\n\nEvery sample is in **C# and VB.NET**, tracking SelectPdf v26.3.\n\n```\n/plugin marketplace add selectpdf/ai-tools\n/plugin install selectpdf@selectpdf\n```\n\nThe right skill activates automatically when you ask it to work with PDFs in a .NET project.\n\nThe same knowledge ships in each tool's native format — Cursor `.mdc`\n\nrules, Copilot `.instructions.md`\n\n, and a Codex `AGENTS.md`\n\nguide. Drop the file into your repo and your assistant is up to speed.\n\nIt's all open source, so you can read exactly what your assistant is being told — and send a PR if you spot something. 👉 [https://github.com/selectpdf/ai-tools](https://github.com/selectpdf/ai-tools)\n\nWant to see the library itself?
