Conciseness

Step 3's ten "Best Practices to Follow" re-teach standard HCL idioms Claude already knows ("Use descriptive snake_case names", variable/output/locals/dynamic-block syntax), lifecycle guidance appears twice ("Lifecycle Rules When Appropriate" then "Lifecycle Rules on Critical Resources"), and date-stamped versions ("Latest: v6.23.0 (Dec 2025)", "as of December 2025") sit outside any deprecated/old-patterns section. Not 2: most sections (workflow, anti-patterns, validation fixes) are project-specific and earn their tokens; not 4: the duplication and known-idiom examples go beyond minor trims.

Actionability

Fully executable throughout: complete HCL blocks (provider pinning, validated variables, S3 lifecycle configuration), exact search-query formats ("datadog terraform provider v3.30 monitor resource documentation"), concrete tool calls (mcp__context7__resolve-library-id, Skill(devops-skills:terraform-validator)), and a Checkov fix table mapping CKV_AWS_300 to the abort_incomplete_multipart_upload rule. Not 4: common cases are covered copy-paste ready with specific remediations for each failure mode.

Workflow Clarity

"Work through these steps in order. Do not skip any step" frames an explicit five-step sequence; Step 4 is a dedicated validation checkpoint with a fix-and-revalidate feedback loop ("Do NOT proceed to Step 5 until all checks pass") and an error-recovery table. Not 4: validation is explicit, looped, and gating — matching the anchor-5 pattern exactly.

Progressive Disclosure

References are well signaled (a when-to-read table, explicit Read paths, one level deep), but scored against the actual bundle: references/modern_features.md is cited three times (Step 2.5 table, Version Awareness, References section) yet absent from references/, and the assets section lists aws-web-app/ and multi-env/ templates that do not exist alongside the present minimal-project/. Not 4: dangling paths are more than minor organization gaps; not 2: the structure, navigation instructions, and reference table are genuinely good.

Specificity

"Generate Terraform modules, configure providers, define variables and outputs, set up remote state backends, and write production-ready HCL (.tf files)" lists five concrete actions plus the file extension — comprehensive coverage matching the anchor-5 example. Not 4: there is no meaningful gap in the action list for this domain.

Completeness

It explicitly answers both what ("Generate Terraform modules, configure providers... set up remote state backends") and when ("Use when creating new Terraform resources, ... or structuring multi-environment configurations") with six concrete trigger phrases, mirroring the anchor-5 example. Not 4: the 'when' clause is fully explicit rather than merely serviceable.

Trigger Term Quality

Triggers include "creating new Terraform resources", "writing infrastructure as code (IaC)", "scaffolding AWS/Azure/GCP cloud infrastructure", "terraform plan/apply workflows", and ".tf files" — covering synonyms, file extensions, and tool commands users would naturally say. Not 4: no commonly used phrasing for this domain is missing.

Distinctiveness Conflict Risk

The Terraform-generation niche is unmistakable, but "working with terraform plan/apply workflows" overlaps with a closely related validation/deployment skill (the body itself delegates to devops-skills:terraform-validator), giving minor overlap risk. Not 5: that shared trigger phrase could route validation-flavored requests to this skill; not 3: all other triggers are clearly and specifically Terraform-generation territory.
