A strong, highly actionable pattern library: executable multi-stage Dockerfiles with pinned tags, non-root users, healthchecks, and layer-cache ordering for every supported ecosystem. Its weaknesses are structural — no explicit generate-and-verify workflow with validation checkpoints, and no progressive disclosure, with all per-language templates inlined in the single file.
Suggestions
Add an explicit workflow section: (1) detect the project's language and package manager, (2) select the matching pattern, (3) generate Dockerfile + .dockerignore, (4) verify with `docker build -t myapp . && docker run` and optionally `docker scout cves myapp:latest` as a validation checkpoint before delivering.
Move per-language Dockerfile templates into reference files (e.g., references/node.md, references/python.md, references/go-rust-java.md) and keep SKILL.md as a conventions-plus-navigation overview so only the relevant template loads into context.
Remove the trivial 'Scaffold Command' section and fold the redundant 'Prerequisites' list into a single line, since creating empty files and Docker version requirements need no explanation.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is almost entirely dense, executable patterns and terse conventions with no explanations of concepts Claude already knows ('Always use multi-stage builds', 'Pin base image tags to specific versions'). Minor padding keeps it below 5: the 'Scaffold Command' section (`touch Dockerfile`/`touch .dockerignore`) is trivial, and 'Prerequisites' repeats the frontmatter compatibility line. | 4 / 5 |
Actionability | Every section is fully executable, copy-paste-ready material: complete multi-stage Dockerfiles for npm, pnpm, pip+venv, Poetry, Go, Rust, and Gradle, a full .dockerignore, HEALTHCHECK and non-root user patterns, build args/labels with usage, and working docker build/run/buildx/scout commands. It clearly matches the anchor 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases'. | 5 / 5 |
Workflow Clarity | The content is a well-organized pattern library rather than a sequenced workflow: there is no explicit procedure (detect the project's language/package manager, pick the matching pattern, scaffold, build) and no validation checkpoint such as 'verify with docker build && docker run' or 'docker scout cves' framed as a step. The sequence exists only implicitly through section ordering, matching the anchor 'Steps listed but validation gaps; sequence present but checkpoints missing or implicit'. | 3 / 5 |
Progressive Disclosure | No bundle files exist (no references/, scripts/, or assets/), and all six full per-language Dockerfile templates (~150 lines) are inlined in SKILL.md. Sections are clearly headed and navigable, but content that would live in separate per-language reference files is inline, so when generating a Python Dockerfile the Go/Rust/Java patterns are dead context — matching the anchor 'Some structure but could be better organized... content that should be separate is inline'. | 3 / 5 |
