# Tools, Sandboxes, and the Plumbing of Agentic Development


- **Date:** Wednesday, Sep 23, 2026
- **Time:** 13:00–13:30 (30 min)
- **Room:** Stage 1
- **Event:** World Congress 2026 North America

## Description

Most conversations about agents end at the model and the prompt, yet the real work happens lower in the stack, in the environment where code runs and tools get invoked. This talk maps out what that layer needs to provide for an agent to do real work safely, then shows a working stack built on those ideas.
