Conciseness

Every step is a bare instruction — "Initialize a new Go module", "Run `go mod tidy`", "Remove TODO comments" — with zero explanation of concepts Claude already knows. Lean throughout; the closing credential note adds non-obvious information, not padding, so it does not fall to 4.

Actionability

Concrete commands (`go get -u ...@latest`, `go mod tidy`, `go build -o /dev/null`, `go test ./...`) plus two complete, executable example files (assets/main.go, assets/provider.go) and specific rename instructions ("demo", "DEMO_*", auth attributes). Fully executable guidance; no pseudocode, so it does not sit at 4.

Workflow Clarity

Clear 10-step sequence with an explicit conditional checkpoint (step 1) and terminal validation steps (`go build -o /dev/null`, `go test ./...`). It stops short of the top anchor because there is no error-recovery loop (e.g., what to do if build/test fails) and `go mod init` in step 3 lacks the actual command — minor validation gaps, matching anchor 4 rather than 5.

Progressive Disclosure

~40-line body with code templates appropriately split into two real, well-signaled one-level-deep references ("follows [the example](assets/main.go)") and clear pointers to sibling skills for next steps. Matches the anchor for a clear overview with easy navigation; the lack of section headers is immaterial at this length.

Specificity

Enumerates concrete deliverables — "workspace layout, go module setup, provider server main.go, and a provider.go with schema and Configure" — matching exactly what the skill's steps produce. This fits the anchor for multiple specific concrete actions with comprehensive coverage; score 4 would require minor gaps, and none exist.

Completeness

Explicitly answers what (scaffolding with Plugin Framework, listing the artifacts) and when, twice: "Use this when scaffolding a new Terraform provider" and "Also use when a user wants to start building a provider... or asks how to begin". Matches the top anchor with concrete trigger phrases.

Trigger Term Quality

Covers natural phrasings users would say: "scaffolding", "start building a provider for a new API", "asks how to begin a terraform-provider-* project" — synonyms (scaffold/build/begin) plus the repo naming convention, the domain equivalent of file extensions. Not 4, since no obviously missing natural term for this niche.

Distinctiveness Conflict Risk

Clear niche — scaffolding a *new* Terraform provider with the Plugin Framework — with distinct triggers unlikely to fire for provider-extension or SDKv2 skills. Minimal conflict risk; not 4, since the new-provider scope is unambiguous.
