Conciseness

Mostly efficient tables and commands, but there are two padded areas: the ~40-line worked example report duplicates a full HCL remediation block that the template itself says to copy from security_checklist.md, and the trailing "References" section re-teaches standard terraform fmt/validate/plan CLI flags (e.g. `-out`, `-var-file`, `-target`) Claude already knows — fitting anchor 3 (some unnecessary explanation, could be tightened) rather than anchor 4's minor-trims profile.

Actionability

Fully executable throughout: exact wrapper invocations with arguments (`bash scripts/run_checkov.sh <path>`), a numbered lookup workflow naming the exact MCP calls (`mcp__context7__resolve-library-id` with the WebSearch fallback string), a fill-in report template, and a concrete missing-tool dialogue with install commands — matching anchor 5 (copy-paste ready, covering common cases).

Workflow Clarity

The 11-step ordered table marks Required vs Recommended gates, enforces ordering constraints (references read before scans), and provides explicit error-recovery feedback loops (Handling Missing Tools flow, common_errors.md error database) — matching anchor 5's clear sequence with explicit validation checkpoints and feedback loops; this is a validation-only skill that explicitly stops at plan, so no destructive-operation cap applies.

Progressive Disclosure

All four reference files (security_checklist.md, best_practices.md, common_errors.md, advanced_features.md) and all four scripts exist in the bundle, are one level deep, and are well signaled via the When/File/Content table; however, the example report inlines a remediation code block that belongs in (and is stated to come from) security_checklist.md, a minor organization gap that keeps it at anchor 4 rather than anchor 5.

Specificity

The description lists several concrete actions — "validating, linting, testing, and automating Terraform configurations" plus "performing dry-run testing with terraform plan" — which goes beyond the 1-2 actions of anchor 3, but the verbs are one level more generic than anchor 5's fully concrete action list and "Comprehensive toolkit" is mild fluff, so it fits anchor 4 (several specific actions, minor gaps such as security scanning, a core capability, being unmentioned).

Completeness

It explicitly answers both questions: what ("validating, linting, testing, and automating Terraform configurations and HCL files") and when ("Use this skill when working with Terraform files (.tf, .tfvars), validating infrastructure-as-code, debugging...") with concrete trigger phrases, exactly matching the anchor 5 exemplar pattern; anchor 4 would require the 'when' clause to be less explicit, which it is not.

Trigger Term Quality

Strong natural coverage — "Terraform files (.tf, .tfvars)", "infrastructure-as-code", "debugging Terraform configurations", "terraform plan", "custom providers and modules", plus the HCL synonym — but anchor 5 is not fully met because common trigger phrasings like "security scan"/"Checkov" and "tflint" for the scanning/linting capabilities are missing, matching anchor 4 (good coverage, a few natural terms missing).

Distinctiveness Conflict Risk

The niche is clear (Terraform validation with .tf/.tfvars/terraform plan triggers), but phrases like "automating Terraform configurations" and "working with custom providers and modules" could pull in requests for generating Terraform or developing providers — closely related but different tasks — so it fits anchor 4 (mostly distinct, minor overlap risk) rather than anchor 5's minimal-conflict profile.
