FastAPI, Typer, SQLModel, Asyncer All bundle their own Agent Library Skills ✨ Let your agents (Codex, Claude, Cursor, etc) help you write good code and avoid gotchas 🤓 New SQLModel and Asyncer just released with their own library skills 🔖 library-skills.io

Sebastián Ramírez @tiangolo.com · 20/06/2026

library-skills now supports uv workspaces and npm/Bun workspaces. ✨ Auto-repair and sync of skills. Improved support for .claude (additional to .agents), it will ask you interactively what to use. Plus several other bug fixes and improvements. library-skills.io

Who would have guessed it! 😱

Sebastián Ramírez @tiangolo.com · 20/05/2026

It seems @fastapi.tiangolo.com 's downloads have more than doubled since early this year 📈 From 8M to 19M per DAY 💥 Maybe because coding agents are so good at writing Python and FastAPI, don't really know 🤔

Typer 0.25.1 comes with its own Library Skills for AI coding agents bundled ✨ Very cool things coming to Typer, your agent should know how to use them 🍰 Thanks @oxykodit.bsky.social ! 🙌 github.com/fastapi/typer

Sebastián Ramírez @tiangolo.com · 01/05/2026

Install the library skills bundled with your dependencies (like FastAPI) for your coding agent 🤖 In Python or Node.js, both versions support both ecosystems ✨ github.com/tiangolo/lib...

So, @thoughtworks.com thinks you should adopt Typer, and I agree 😎 CLIs are key for AI stuff, Python is the language where you (and agents) can build things the fastest, and Typer is how you build CLIs in Python 🤘 www.thoughtworks.com/radar/langua...

Now you can ✨ literally use Literal ✨ with Typer. Here's Typer 0.19.0 🚀 This adds support for typing.Literal, for defining CLI parameters that should take one of multiple options. Probably the most requested feature just landed. 🎉 github.com/fastapi/typer
