sandboxed tool executors become default in production agents

Teams are running agent tool actions in isolated runtime environments with scoped capabilities and strict egress control (CNCF sandboxing landscape).

implementation shift

Tool calls now execute through dedicated sandboxes with per-action policy checks and short-lived credentials.

reliability signal

• Lateral movement risk declines in tool-heavy workflows.
• Incident blast radius shrinks under compromised plugins.
• Runtime policy complexity increases operational overhead.

my take

Isolation is becoming the practical boundary between useful autonomy and unacceptable risk.
