devcontainer-security

This is a security-hardening guide for VS Code DevContainers used to run coding agents. The document itself contains no malicious code or instructions to fetch and execute remote payloads. It sensibly recommends reducing IPC and credential exposure and using a read-only Docker proxy. Main risks are operational: the guide accepts several trade-offs (readable agent credentials, network egress, workspace write access) which increase exposure if an agent or a dependency is compromised. The security of the overall setup depends on correct implementation of external components (Docker proxy) and careful handling of tokens/credentials. The postStartCommand deletion is a legitimate cleanup step but is destructive if misconfigured. Overall: no evidence of malware, but moderate residual risk due to accepted operational trade-offs and reliance on external proxy implementation.
