Quality

Content

78%Weight 40%Scale 1-5

Reviews 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 Terraform style guide with concrete examples and a validation checkpoint. Its main weaknesses are a dangling SECURITY.md reference with no supporting bundle file and limited true progressive disclosure into separate materials.

Suggestions

Create a SECURITY.md reference file (and a references/ directory) or inline the security guidance so the 'Refer to SECURITY.md' pointer resolves to a real file.

Remove the duplicated terraform {} block in the Version Pinning section and the repeated HashiCorp link at the end to tighten conciseness.

Add an explicit fix-and-retry loop after the validation step (e.g., 'if validate fails, correct and re-run until clean') to strengthen workflow clarity.

DimensionReasoningScore

Conciseness

The body is largely lean with concrete HCL examples and minimal concept-padding, though the version-pinning section repeats an already-shown terraform block and the trailing HashiCorp link duplicates the intro reference.

4 / 5

Actionability

It provides copy-paste-ready HCL blocks (terraform.tf, variables.tf, resources, providers), specific commands (terraform fmt -recursive, terraform validate), and named tooling (tflint, checkov, tfsec) covering the common cases.

5 / 5

Workflow Clarity

A clear five-step generation sequence plus a validation checkpoint (terraform validate) and a closing review checklist are present, but there is no explicit fix-and-retry feedback loop.

4 / 5

Progressive Disclosure

Sections are well-organized, but the body references SECURITY.md ("Refer to SECURITY.md") while no references/scripts/assets bundle exists, and most guidance is inlined into one file rather than split out one level deep.

Description

73%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A clear, third-person description that concretely states both what the skill does and when to use it for a distinct Terraform niche. It is slightly held back by listing activities rather than multiple discrete concrete actions and by omitting a few natural synonyms.

DimensionReasoningScore

Specificity

It names the domain (Terraform HCL) and concrete actions ("Generate Terraform HCL code", "following…style conventions and best practices"), but the writing/reviewing/generating list names activities rather than distinct concrete actions, so it is not comprehensive.

3 / 5

Completeness

Both 'what' ("Generate Terraform HCL code following…conventions") and 'when' ("Use when writing, reviewing, or generating Terraform configurations") are explicit, though the 'when' clause could be slightly more specific.

4 / 5

Trigger Term Quality

Natural phrases users would say appear ("writing…Terraform configurations", "reviewing…Terraform configurations", "Terraform HCL"), but common synonyms like ".tf", "IaC", or "infra as code" are missing.

4 / 5

Distinctiveness Conflict Risk

The Terraform/HashiCorp/HCL niche is clearly scoped and unlikely to trigger for unrelated skills, with minimal overlap risk.
