Bluebag is a production skills runtime for AI agents. Use Anthropic-style agent skills in your own app without custom infra. Load public skills, sync with a CLI, and run them safely across any LLM using Vercel AI SDK or LangChain.
When Anthropic published their Skills system, it immediately clicked for me.
The idea is simple but powerful: give agents a filesystem-based skill library (instructions, scripts, reference files) and let them progressively load only what they need.
The problem? In my own projects, I wasn’t using Claude. Most workloads ran on Gemini for cost and flexibility, which meant I couldn’t use Anthropic’s Skills directly, even though I really wanted that architecture for remote agents built with Vercel’s AI SDK.
So we built a model-agnostic, Agent Skills runtime that works with any remote agent.
Bluebag handles the hard parts of running skills at scale: sandbox lifecycle, skill reusability, dependency installation, concurrent file access, and secure execution.
Right now, you can:
- Package instructions, metadata, scripts, and references into a Skill directory
- Run Python or JS inside skills (with automatic dependency installs)
- Let agents create, read, and download files via a files API
- Manage everything with a CLI (push/pull), a TypeScript SDK, and a lightweight web app

Would love to see what people build with it. The free tier is intentionally generous 🙂
