Conciseness

The Provectus Conventions section is dense and earns every token, but the middle of the body restates standard Terraform knowledge Claude already has and duplicates the reference files: the count vs for_each decision table and GOOD/BAD examples appear again in code-patterns.md, block ordering in code-patterns.md, and naming/file-organization conventions in quick-reference.md's Common Patterns. Mostly efficient but with real tightening opportunities — not 4, since the duplication is more than minor; not 2, since there is no padded prose and the opinionated conventions genuinely add non-obvious rules.

Actionability

Fully executable throughout: exact constraint syntax ('required_version = "= X.Y.Z"'), concrete locals.tf and merge(local.required_tags, ...) HCL, copy-paste plan -out apply commands, named MCP tools with an HTTP-API fallback URL, and exact CLI commands ('trivy config .', 'checkov -d .'). Code examples are complete and runnable.

Workflow Clarity

Multi-step processes are explicitly sequenced with validation checkpoints: the apply workflow is plan -out → 'terraform show plan.tfplan' → 'Wait for explicit approval' → apply the saved plan (a validation gate on a destructive operation), module version resolution has an MCP-first path with a defined fallback loop, cost review is 'Plan → cost review → build', and security scans must 'pass before a plan'. A pre-commit checklist is referenced, matching the top anchor's sequence-plus-validation-plus-checklist profile.

Progressive Disclosure

All seven in-body reference links resolve to real files in the bundle, the anchors used (e.g., aws-stack-layout.md#security-baseline, code-patterns.md#count-vs-for_each-deep-dive, quick-reference.md#troubleshooting-guide) match actual headings, and references are one level deep (they link only back to SKILL.md, never onward to further files). A closing References section summarizes each file, making navigation easy — matching the top anchor.

Specificity

The description enumerates many concrete actions with tool specifics: 'creating modules, writing tests (native test framework, Terratest), setting up CI/CD pipelines, reviewing configurations, choosing between testing approaches, debugging state issues, implementing security scanning (trivy, checkov), or making infrastructure-as-code architecture decisions' — comprehensive coverage across the skill's scope, matching the anchor for multiple specific concrete actions.

Completeness

It explicitly answers both questions: 'what' is stated first ('Provides Terraform module, testing, CI/CD, security and AWS stack-layout guidance layered with Provectus conventions (exact version pinning, required tags, ephemeral secrets)') and 'when' follows with a concrete 'Use when working with Terraform - ...' clause listing eight trigger scenarios, plus explicit exclusions — a clear match for the top anchor.

Trigger Term Quality

Good keyword coverage includes natural terms users would say: 'Terraform', 'Terratest', 'CI/CD pipelines', 'trivy', 'checkov', 'infrastructure-as-code', 'OpenTofu', 'state'. A few natural synonyms are missing (e.g., 'HCL', '.tf files'), which places it at 'good coverage; a few natural terms missing' rather than the comprehensive-synonym anchor at 5.

Distinctiveness Conflict Risk

The Terraform/IaC niche is distinct with tool-specific triggers (Terratest, trivy, checkov) and the closing boundary 'Does not cover application code, Kubernetes manifests, or CloudFormation/CDK' explicitly fences off adjacent skills, giving minimal conflict risk.
