## What it does

Contain code an agent generates or is induced to run. Execute in a sandboxed container with least privilege and deny-by-default egress, prefer parameterised APIs over raw shell, and treat any string reaching a subprocess or interpreter as attacker-controlled. Use when adding a code interpreter, shell tool, subprocess call, or eval-style API to an agent. Do NOT use for eval/exec appearing in ordinary application code — that is \`code-safety\`.
