Bluebag AI – Agent Skills Platform for AI-SDK and LangChain Agents

Summary: Bluebag AI implements Anthropic's Agent Skills protocol for remote agents, enabling skill reuse across multiple LLMs like Claude, GPT, Gemini, and Llama without code changes. It provides sandboxed environments, automatic retries, and integrates with Vercel AI-SDK or Langchain for scalable skill execution.

What it does

Bluebag bundles instructions, scripts, and reference files into skill directories that run Python or JavaScript with automatic dependency installation. It offers a files API for file creation and temporary downloads, managed via CLI, TypeScript SDK, and a web app.

Who it's for

Developers building remote AI agents on platforms like Vercel AI-SDK or Langchain who need reusable, production-ready skill infrastructure compatible with various LLMs.

Why it matters

It solves the challenge of running and managing reusable agent skills remotely at scale while allowing seamless model switching without rewriting code.
