The description says 'scaffolding a new Terraform provider' but does not list any concrete actions (e.g., generating resource schemas, creating provider configuration, setting up acceptance tests). It's a single vague action.

It has a 'when' clause ('Use this when scaffolding a new Terraform provider') but the 'what' is essentially missing — it doesn't describe what the skill actually does or produces. The 'what' is extremely weak, effectively just restating the trigger.

It includes 'Terraform provider' and 'scaffolding' which are relevant keywords a user might use, but misses common variations like 'terraform plugin', 'provider boilerplate', 'new provider project', 'terraform-plugin-sdk', 'terraform-plugin-framework'.

'Terraform provider' is a fairly specific domain, which helps with distinctiveness, but 'scaffolding' is vague enough that it could overlap with general code scaffolding or project generation skills.

The skill is lean and efficient. It doesn't explain what Terraform is, what a provider is, or how Go modules work. Every step earns its place and assumes Claude's competence.

The steps include specific commands (`go get`, `go mod tidy`, `go build`, `go test`), but the reference to `assets/main.go` is unresolvable since no bundle files are provided. The Go module initialization step ('Initialize a new Go module') lacks the specific command (`go mod init`). Key details like the module path are missing.

Steps are clearly sequenced and include a conditional check at the start, plus build and test validation at the end. However, there's no explicit error recovery or feedback loop — if `go build` or `go test` fails, there's no guidance on what to do next, which matters for a scaffolding workflow.

The skill references `assets/main.go` as an example file, which is good progressive disclosure in principle, but the bundle file is not provided, making the reference broken. The content is appropriately concise for the SKILL.md level, but the missing asset undermines the structure.
