Agent sandboxing in three layers: primitives, runtime, platform — plus an AGENTS.md handbook playbook
blaizedsouza · x · 2026-09-11
An explainer argues agent sandboxing stacks three layers: a primitive layer (Firecracker, Litebox) controlling kernel, networking down to TAP/TUN, filesystems and resources; a runtime layer (e.g. E2B) that boots an isolated runtime, executes agent code and manages its lifecycle; and a platform layer on top for higher-level orchestration. Also linked: an article on writing a repo-owned AGENTS.md handbook instead of vendor-named rule files, claiming it outperforms up to five vendor config files.
