WebAssembly (WASM) Emerges as Standard for Agent Tool Isolation

WebAssembly has established itself as the leading sandboxing runtime for multi-agent tool execution in production environments. Unlike traditional Linux container sandboxes that require seconds to start, WASM modules instantiate in sub-millisecond timeframes with negligible memory overhead. Hardware-isolated memory boundaries ensure untrusted third-party agent code and generated scripts cannot compromise host file systems or cloud networks.
