Conciseness

The body is almost entirely executable material — scaffold commands, HCL blocks, and a command reference — with no concept explanations Claude already knows (no "Terraform is a tool..." padding). It falls short of anchor 5 because ~300 lines of full module implementations (VPC with route tables, RDS, S3) and the structure tree duplicating the scaffold commands could be trimmed or moved out of SKILL.md.

Actionability

The scaffold script, complete HCL patterns, and the `terraform -chdir=infra ...` commands are copy-paste ready and cover the common cases. Minor gaps keep it below anchor 5: `main.tf` and the database module reference `var.vpc_cidr`, `var.db_instance_class`, `var.db_name`, `var.db_username`, and `var.db_password`, which are not declared in the shown `variables.tf`, and no compute module code is provided despite being wired into the root module.

Workflow Clarity

"Common Commands" lists init, fmt, validate, plan, apply in a sensible implicit order, but it reads as a command menu rather than a sequenced workflow, and there is no validation checkpoint such as "review the plan output before apply" for what are destructive operations (apply/destroy). Per the judging guidelines, missing validation steps in destructive workflows cap this dimension at 3.

Progressive Disclosure

Section organization is clear (Scaffold, Structure, Conventions, Patterns, Commands, Integrations), but the file is a monolithic ~400 lines: complete module implementations that clearly belong in reference files are fully inlined, and there are no external references at all. This sits between anchor 2 (content that belongs in separate files is inlined) and anchor 4 (content appropriately split), matching anchor 3's 'content that should be separate is inline' with decent internal structure.

Specificity

The description enumerates concrete deliverables — "provider configuration (AWS/GCP/Azure), modular structure, remote state, variables, outputs, workspaces, and common resource patterns" — which is several specific items with only minor gaps (e.g., the scaffold/init workflow is implied but not named). It falls below anchor 5 because it rests on a single action verb ("Scaffold") plus a component list rather than multiple distinct concrete actions, and above anchor 3 because coverage of the Terraform scaffolding domain is broad, not just 1-2 actions.

Completeness

The "what" is clear and concrete ("Scaffold Terraform 1.9+ infrastructure with provider configuration..."), but there is no "Use when..." clause or equivalent explicit trigger guidance. Per the judging guidelines, a missing 'Use when...' clause caps completeness at 3 even with a strong 'what'.

Trigger Term Quality

Strong natural keywords: "Terraform", "infrastructure", "AWS/GCP/Azure", "remote state", "variables, outputs, workspaces" — terms users would genuinely say. It sits below anchor 5 because common variations like "infrastructure as code", "IaC", "HCL", or ".tf" are missing, and above anchor 3 because the included terms go well beyond a couple of generic keywords.

Distinctiveness Conflict Risk

Naming "Terraform" with provider specifics carves a clear niche distinct from generic infra or config-management skills. It is not a 5 because the description doesn't disambiguate from closely related skills (e.g., a Terraform review/migration skill or other cloud-provisioning skills) — minor overlap risk remains.
