mitsuhiko: AST interpreter alone is too fragile a sandbox for code execution
mitsuhiko · x · 2026-10-10
mitsuhiko explains his sandboxing trade-offs: he wasn't comfortable relying on an AST interpreter as the only isolation mechanism — significant work to build and tricky to sandbox — and he isn't even sure wasm/worker alone is sufficient isolation. Useful perspective for anyone building AI agent code-execution environments.
