Agents That Write Their Own Tools at Runtime (Sandhya Subramani (AWS))
talk · Story page
Subramani's Strands agent starts with zero tools and writes the ones it needs at runtime, off a system prompt plus three primitives: editor, shell and load_tool. She also covers the sandboxing, constrained permissions and observability you'd want first.
In plain words
- Sandhya Subramani demonstrated an artificial intelligence assistant that writes extra computer programs when a task requires them.
- It creates a program and starts using it immediately, without restarting.
- She described limiting what it can access and tracking its actions before trusting it with real work.
- Developers could let assistants tackle new tasks without having to build every tool ahead of time.
