82%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, highly actionable skill body built around executable HCL and commands, with a validation checkpoint in the build sequence. Main gaps are minor redundancy in the source_ami_filter blocks and the absence of an explicit validate-fix-retry feedback loop.
Suggestions
Deduplicate the ubuntu source_ami_filter block — define it once and reference it from the Basic Template, Common Source AMI Filters, and Multi-Region sections to reduce repetition.
Add an explicit feedback loop after `packer validate` (e.g., 'If validation fails, fix the template and re-run validate before building') since AMI builds are long-running and cost-incurring.
Consider moving the catalog of source_ami_filter examples (Ubuntu, Amazon Linux, multi-region) into a references file and keeping only one inline example in SKILL.md to improve progressive disclosure.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and mostly code with no padding about what AMIs or Packer are, though the ubuntu source_ami_filter block is repeated across three sections and could be trimmed. | 4 / 5 |
Actionability | Provides a fully executable, copy-paste-ready HCL template plus concrete packer init/validate/build commands covering the common cases. | 5 / 5 |
Workflow Clarity | The Build Commands section sequences init, validate, then build with `packer validate` as an explicit checkpoint, but there is no explicit error-recovery feedback loop for this long-running, cost-incurring operation. | 4 / 5 |
Progressive Disclosure | Well-organized into clear sections with external references clearly signaled in a References list, but no bundled reference files exist and some content (repeated filters, multi-region variant) is inlined that could be split out. | 4 / 5 |
