Conciseness

The body is efficient and assumes Claude's Terraform knowledge — no explanations of what Terraform or VPCs are, just structure trees, complete HCL, and a test snippet. Minor trimming is possible: the 'Purpose' and 'When to Use' sections largely restate the description and opening line, which keeps it below the lean anchor 5.

Actionability

The guidance is fully executable: complete main.tf/variables.tf/outputs.tf for a working VPC module with variable validation and tagging, a copy-paste module-composition example wiring vpc outputs into rds, the exact directory layout, and a runnable Terratest file. The common case (build a production VPC module and compose it) is covered end-to-end.

Workflow Clarity

There is an implicit topical sequence (structure → pattern → example → best practices → composition → testing) but no explicit ordered steps for building a module, and no validation checkpoints (terraform validate/fmt/plan) before provisioning. Since Terraform applies are effectively batch infrastructure changes and the only verification shown is a post-apply Terratest, the missing validate-before-apply feedback loop caps this at 3 rather than 4.

Progressive Disclosure

Real one-level-deep reference files exist and are pointed to ('See references/aws-modules.md and references/oci-modules.md'), but the pointer is a single plain-text line buried at the end of Best Practices rather than a clearly signaled references section with links. Coverage is also asymmetric: Azure and GCP appear in the structure tree yet have no reference files or pointers, and ~100 lines of AWS VPC module code are inlined while per-cloud detail belongs in the references — matching the anchor for 'references present but not clearly signaled; content that should be separate is inline'.

Specificity

The description lists several concrete actions — 'Build reusable Terraform modules for AWS, Azure, GCP, and OCI infrastructure', 'standardizing cloud provisioning', 'implementing reusable IaC components' — all in third person. It falls short of a 5 because the action set is fairly generic ('build', 'standardize', 'implement') without naming specific deliverables like versioned releases, tested modules, or module composition.

Completeness

It explicitly answers both questions: the 'what' ('Build reusable Terraform modules for AWS, Azure, GCP, and OCI infrastructure following infrastructure-as-code best practices') and a concrete 'when' ('Use when creating infrastructure modules, standardizing cloud provisioning, or implementing reusable IaC components'). This matches the anchor-5 example structure of concrete actions followed by explicit trigger phrases.

Trigger Term Quality

Natural trigger terms include 'Terraform modules', 'infrastructure modules', 'cloud provisioning', 'IaC components', and the four cloud names. A few natural terms users would say are missing — e.g. 'HCL', '.tf', 'module registry', or 'infrastructure as code' spelled out — so it does not reach comprehensive anchor 5.

Distinctiveness Conflict Risk

Terraform module authoring is a clear niche, but the broad 'standardizing cloud provisioning' and 'infrastructure-as-code best practices' phrasing creates minor overlap risk with general cloud-architecture or per-cloud IaC skills, so it does not fully match the minimal-conflict anchor 5.
