A highly actionable, well-organized code skill with copy-paste-ready Packer templates and commands. The main gaps are minor verbatim duplication of the Ubuntu filter block and a command-menu presentation that lacks an explicit validation feedback loop for costly AWS builds.
Suggestions
De-duplicate the Ubuntu source_ami_filter block: keep it once in Common Source AMI Filters and reference it from the Basic Template, and remove the repeated Amazon EBS Builder link from the References section since it already appears at the top.
Convert Build Commands into a sequenced workflow with an explicit feedback checkpoint, e.g. "Run `packer validate .` and fix any template errors before building; only proceed to `packer build` once validation passes."
Add a one-line note in Build Commands to confirm the AWS region/credentials are set (e.g. verify `AWS_REGION`) before `packer build`, since misconfigured credentials are a common build failure.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean, assumes Claude's competence, and avoids explaining concepts like what an AMI or Packer is, but the Ubuntu source_ami_filter block is duplicated verbatim between the Basic Template and Common Source AMI Filters sections and the Amazon EBS Builder link is repeated in References — genuine tightening opportunities that keep it at level 2 rather than 3. | 2 / 3 |
Actionability | Provides fully executable HCL templates (packer/source/provisioner blocks) and bash commands (packer init/validate/build, env vars) with specific owner account IDs, regions, and instance types — copy-paste ready, matching the level-3 anchor. | 3 / 3 |
Workflow Clarity | Build Commands show an init→validate→build sequence with a real `packer validate` checkpoint, but they are presented as a command menu without an explicit validate-then-proceed feedback loop for a costly/stateful AWS operation, so it does not reach level 3; it is above level 1 because a validation step is present. | 2 / 3 |
Progressive Disclosure | A well-sectioned single self-contained file with clearly labeled sections and one-level external doc links, no nested references and no genuine need to split into bundle files, matching the level-3 anchor of clear organization and easy navigation. | 3 / 3 |
