ToolRaven rule IDs intentionally do not reuse Hadolint DL codes. Inline suppression is supported with # toolraven-ignore TRD001: reason immediately above the relevant instruction.

About Quick Dockerfile Review

Quick Dockerfile Review checks a focused ToolRaven ruleset for common security, reproducibility, image-size, and build-cache mistakes. Each finding identifies the source line and explains what this local checker can establish.

This is not Hadolint and does not parse a full Dockerfile AST or run ShellCheck. Use the included Hadolint commands for authoritative CI enforcement, especially when shell semantics, build arguments, or advanced Dockerfile syntax matter.
