Skill Library (Voyager)(SL)
An agent writes reusable, executable skills (programs) for behaviors it discovers, stores them in a library indexed by embeddings of their descriptions, and later retrieves and composes them into more complex skills. The library grows as a form of procedural memory, so capability compounds over time without gradient updates or catastrophic forgetting.
In 30 seconds
- What
- Agent writes executable code for discovered behaviors, stores them in an embedding-indexed library, and composes them into complex skills that grow without retraining.
- When to use
- Open-ended learning where the agent discovers many reusable behaviors over time and needs to build on prior discoveries without forgetting or retraining.
- Watch out
- Code quality and correctness degrade rapidly if execution feedback is noisy or the refinement loop fails to catch bugs before library storage.

Skill Library (Voyager): Overview
An agent writes reusable, executable skills (programs) for behaviors it discovers, stores them in a library indexed by embeddings of their descriptions, and later retrieves and composes them into more complex skills. The library grows as a form of procedural memory, so capability compounds over time without gradient updates or catastrophic forgetting.
- Skills stored as executable code, not weights
- Embedding-indexed library for retrieval by meaning
- Automatic curriculum proposes the next skill to learn
- Iterative code refinement from execution feedback
- Composition of simpler skills into complex ones
- Compounding capability without catastrophic forgetting
