Conciseness

The body is largely command-first and lean (gcloud/terraform commands, MCP argument lists, parser constraints), but the exponential-backoff-with-jitter policy is duplicated in Phase 3 and Phase 4, and the 'terraform validate && terraform plan -out=tfplan && terraform show -json tfplan > tfplan.json' chain is repeated three times (Phases 1, 2, and 5). Mostly efficient with some tightening possible, matching anchor 4 rather than anchor 5's 'every token earns its place'.

Actionability

Commands are copy-paste ready with full flags ('gcloud design-center spaces generate-terraform-assessment-report <space_id> --location=<location> --project=<project_id> --terraform-plan="<scratch_directory_path>/tfplan.json" --format=json'), MCP tools are named with enumerated arguments and a concrete iacModule JSON example, and common failure cases get exact remediation HCL ('create_service_account = false') and a specific public image ('us-docker.pkg.dev/cloudrun/container/hello'). Fully executable guidance covering the common cases, so anchor 5 rather than anchor 4's 'minor gaps'.

Workflow Clarity

Six clearly sequenced phases with an explicit index, mandatory validation checkpoints (secret-safe and state-isolation verification, mandatory plan export to JSON), explicit exit criteria with an iteration cap of three, verify-revision-before-retry on timeouts, LRO polling with a 30-60s interval, a five-attempt troubleshooting threshold, and Phase 6 verification. Full feedback loops and checklists match anchor 5; it is not anchor 4 because validation checkpoints are explicit at every phase boundary, not mostly present.

Progressive Disclosure

The body is a well-organized overview with an index and clearly signaled one-level links to real files ([attribution](references/attribution.md), [design](references/design_guide.md), [infra-deployment-debugging](references/troubleshooting_guide.md) all exist), but several bundle assets (scripts/fetch_terraform_template.py, scripts/list_terraform_templates.py, planner/generator/validator instructions) are only reachable via a second reference level through design_guide.md and troubleshooting_guide.md. Good structure with minor organization gaps matches anchor 4; not anchor 5 because some content is nested two levels deep rather than directly signposted.

Specificity

The description enumerates six concrete actions spanning the full lifecycle — 'Designing GCP infrastructure with Terraform', 'Validating local HCL', 'Performing best-practice plan scans', 'Importing templates to Application Design Center (ADC)', 'Deploying templates', 'Troubleshooting deployment failures' — which is comprehensive coverage, matching anchor 5 rather than anchor 4's 'minor gaps in coverage'. It is written in third person ('Processes GCP infrastructure design and deployment workflows'), so no voice penalty applies.

Completeness

Both questions are explicitly answered: the 'what' is stated up front ('Processes GCP infrastructure design and deployment workflows within Application Design Center (ADC)') and the 'when' is an explicit 'Use when:' list of six concrete trigger scenarios, further reinforced by a 'Boundaries:' exclusion clause. This matches anchor 5's 'clearly and explicitly answers both what AND when with concrete trigger phrases'.

Trigger Term Quality

Good natural keyword coverage — 'GCP', 'Terraform', 'HCL', 'ADC', 'deploy', 'troubleshooting deployment failures' are phrases users would naturally say — but common synonyms like 'Google Cloud', 'infrastructure as code'/'IaC', or '.tf' are absent. This fits anchor 4 ('good keyword coverage; a few natural terms missing') and not anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The description carves a clear niche (ADC + GCP + Terraform) and adds explicit boundaries — 'Only use for GCP-specific cloud infrastructure', 'Only use for Terraform coding within the ADC context' — minimizing overlap with generic Terraform or cloud skills. This matches anchor 5's 'clear niche with distinct triggers; minimal conflict risk'.
