Use when finishing a task that changed code, config, scripts, prompts, or documentation. Runs the final build/test/lint/review loop, fixes reasonable issues, and reports remaining findings or skipped checks before the final answer.

Use when checking Docker image versions or working with container registries. Skopeo is the required tool for registry queries - never parse Docker Hub web pages.
Use when working with Elm projects. Requires running elm-test and elm-review for quality assurance.
Use when working with version control. jj (Jujutsu) is the preferred VCS - never use git commands directly when jj can do the job. Covers mental model, workflows, and Nix integration.
Use when working with NixOS configurations, Home Manager setups, Nix flakes, services, or troubleshooting Nix builds. Covers creating new configurations, modifying existing ones, adding packages, setting up services, writing modules, and debugging build failures.
