Conciseness

The 72-line body is pure directive guidance — no explanation of concepts Claude already knows (no "Terraform is..." padding), no fluff; every line states a rule, path, or command. The one version mention ("tfplugindocs generates action docs with Terraform v1.14.0+") is a necessary compatibility constraint, not date-conditional instruction, so it does not warrant a penalty. Not 4: there is no over-explanation left to trim.

Actionability

Core workflow is executable and copy-paste ready: exact template paths (docs/index.md.tmpl, docs/resources/<name>.md.tmpl, etc.), `go generate ./...`, and the full `go run github.com/hashicorp/terraform-plugin-docs/cmd/tfplugindocs generate --provider-name <provider_name>` invocation. Not 5: step 5's validations are descriptive rather than executable ("Verify examples are valid HCL" names no command such as a fmt/validate check), and "Use the HashiCorp preview process" points to a process without linking the reference section that explains it. Not 3: the generation and file-layout guidance is fully concrete, not pseudocode.

Workflow Clarity

A clearly sequenced 7-step workflow with an explicit validation step (step 5 lists three concrete checks), a feedback loop ("Re-run generation after every schema or template edit"), and a recovery path (step 7 troubleshooting with a specific diagnostic checklist: tag format, tag source branch, manifest file, publication status). Matches the anchor-5 pattern of sequence + explicit validation + error-recovery loop.

Progressive Disclosure

The body is a lean overview that defers source-backed detail to a single, clearly signaled, one-level-deep reference (`references/hashicorp-provider-docs.md`, verified to exist with the exact sections cited: "Example File Conventions" and "Action Pages"), and instructs loading only needed sections. Not 4: structure, signaling, and file split are all appropriate with no organization gaps.

Specificity

"Create, update, and review Terraform provider documentation for Terraform Registry using HashiCorp-recommended patterns, tfplugindocs templates, and schema descriptions" lists multiple specific concrete actions plus the exact mechanisms (tfplugindocs, templates, schema descriptions), giving comprehensive coverage. Not 4: the action list and tooling coverage go beyond "several specific actions; minor gaps".

Completeness

Explicitly answers both: what ("Create, update, and review Terraform provider documentation for Terraform Registry..." with named tooling) and when ("Use when adding or changing provider configuration, resources, data sources, ephemeral resources, list resources, functions, actions, or guides; when validating generated docs; and when troubleshooting missing or incorrect Registry documentation"). Matches the anchor-5 example structure exactly.

Trigger Term Quality

Natural terms a Terraform practitioner would actually say are comprehensively covered: "provider documentation", "Terraform Registry", "provider configuration", "resources", "data sources", "ephemeral resources", "list resources", "functions", "actions", "guides", "tfplugindocs", "validating generated docs", "troubleshooting missing or incorrect Registry documentation". Not 4: no common variation of the domain vocabulary is missing.

Distinctiveness Conflict Risk

Clear niche (Terraform provider documentation for the Registry) with distinct triggers — tfplugindocs, template paths, Registry publication — that no general Terraform or documentation skill would share. Minimal conflict risk. Not 4: the tool- and Registry-specific vocabulary leaves essentially no overlap with neighboring skills.
