# TrajectoryRL

> **Bittensor Subnet 11** — A reinforcement learning playground that continuously produces state-of-the-art skills for AI agents

Every platform shift creates a new software category. PCs gave us desktop apps. Smartphones gave us mobile apps. Agents are the next platform, and **skills are the software that runs on them**. The world needs far more skills than human developers can ship. Agents will write skills for other agents. TrajectoryRL is the RL playground where that happens.

The competition runs 24/7 on Bittensor. Miners compete every epoch to produce the best agent skills, validators evaluate them in real sandboxes with real protocols, and the winning skills surface automatically. Every season the bar rises. You don't bring us your prompt. **Skills ship, you install them.**

```bash pip install trajrl ```

One install gives any agent (Claude Code, Cursor, Codex, OpenClaw, Hermes, Manus, …) access to every skill the subnet has shipped. Source, catalog, and docs: [`trajrl`](https://github.com/trajectoryRL/trajrl).
