devcontainer-sandboxing

Devcontainer sandboxing automatically enforces least-privilege isolation by restricting host access, disabling privileged modes, and preventing risky mounts. This creates a hardened, reproducible development environment that blocks unauthorized interactions while maintaining workflow integrity.

Sandboxing eliminates host access vulnerabilities, privileged container escalation, insecure volume mounts, and uncontrolled repository interactions. It enforces branch-prefix discipline and per-agent package ownership to prevent lateral movement and unauthorized code changes in multi-agent setups.

Yes. The Skill specifies sandbox scope for both single- and multi-agent modes, enforcing per-agent package ownership and branch-prefix discipline. Secure Git operations and PR-based collaboration ensure agents operate within controlled, isolated boundaries.

Yes. Docker is a required dependency for devcontainer sandboxing. The Skill automates sandbox creation and hardening within Docker-based devcontainers to enforce container isolation and security patterns.

The Skill verifies security hardening through automated checks, restricts repository interactions to approved patterns, and enforces branch and package ownership rules. This prevents configuration drift and ensures consistent, compliant development workflows.
