Simple AI Agent Sandbox: Ephemeral Docker Isolation for Every AI Session

Tue, 26 May 2026 00:00:00 +0000

AI agents are exciting. Give a capable LLM the ability to run code, write files, and execute shell commands, and suddenly you have a system that can actually do things rather than just talk about them. But that power comes with a sharp edge: an agent that can run arbitrary shell commands can do a lot of damage if it goes sideways.

The typical response is to add guardrails at the prompt level: “don’t delete files”, “only modify files in this directory”. This works until it doesn’t. Prompts are soft constraints. A Docker container is a hard one.

That’s the idea behind simple-ai-agent-sandbox: every agent session gets its own fresh, ephemeral Ubuntu container. When the session ends, the container is destroyed. Clean slate, every time.
