devcontainer-setup

No explicit malicious payload is visible in this configuration fragment (no hardcoded secrets, suspicious domains, or overt exfiltration logic). However, the configuration executes an uninspected post-create script (/opt/post_install.py) and installs external components (a devcontainer feature and a VS Code extension). Combined with elevated container network capabilities (NET_ADMIN/NET_RAW) and mounting of user/agent configuration, this creates a meaningful supply-chain/setup risk that warrants review of the Dockerfile, the post_install.py script, and the referenced feature/extension source integrity and behavior.
