Subject: Filesystem sandbox for agents
The Gist: jai is a lightweight Linux containment tool for AI coding agents. It sits between “run the agent as your real user” and “build a full container/VM,” letting the agent work in the current directory while keeping the rest of the filesystem constrained. Home can be copy-on-write or hidden, temp dirs are private, and the tool is explicitly framed as reducing blast radius rather than providing perfect isolation.
Key Claims/Facts:
- Current directory first: The agent gets full read/write access in its working directory.
- Home containment: The user’s home directory is either copy-on-write or replaced with an empty private home.
- Rest locked down:
/tmp,/var/tmp, and everything outside the workspace/home setup are restricted, with the project positioned as a simpler alternative to hand-building bwrap/container wrappers.
Discussion Summary (Model: gpt-5.4-mini)
Consensus: Cautiously optimistic, but with a lot of skepticism about whether the sandbox is strict enough by default.
