Conciseness

The service-mapping tables and pattern lists are mostly token-efficient, but there is duplication and generic filler: the body's comparison tables overlap `references/service-comparison.md`, Pattern 4 and the 'Cloud-Agnostic Architecture' section repeat the same Kubernetes/PostgreSQL/MinIO advice, and Best Practices items like 'Follow security best practices', 'Design for failure', and 'Train teams on multiple clouds' restate cloud knowledge Claude already has. This matches 'mostly efficient but includes some unnecessary explanation' rather than 4, where only minor trimming would be needed.

Actionability

There is some concrete guidance — specific service mappings (EKS/AKS/GKE/OKE), named abstraction choices (Terraform, MinIO, Prometheus/Grafana), and per-provider pricing models — but the promised 'decision framework' never materializes as an actual procedure: no selection criteria, weighting, evaluation steps, commands, or a worked example of choosing a service. Guidance like 'Use managed services when possible' and 'Right-size resources' stays high-level, matching the anchor for concrete-but-incomplete guidance rather than the mostly-executable level 4.

Workflow Clarity

The Migration Strategy gives a coherent four-phase sequence (Assessment, Pilot, Migration, Optimization) with sub-steps, but validation is vague ('Test thoroughly', 'Monitor performance') with no explicit checkpoints or feedback loops such as how to validate a pilot before proceeding or when to roll back. This is 'steps listed but validation gaps' rather than level 4's 'most checkpoints present'; no destructive/batch cap applies since this is a design skill.

Progressive Disclosure

The body is well-sectioned and points to two real one-level-deep bundle files (`references/service-comparison.md`, `references/multi-cloud-patterns.md`, both verified to exist and contain the deeper detail), which is good structure with most content appropriately placed. Not a 5 because the patterns reference is a bare, unlabeled link stranded at the end of the Cost Comparison section instead of the Multi-Cloud Patterns section it relates to, and the comparison tables substantially duplicate the reference file inline.

Specificity

The description names the domain ('multi-cloud architectures') and a couple of concrete actions ('select and integrate services across AWS, Azure, GCP, and OCI'), matching the anchor for domain plus 1-2 concrete actions. It is not a 4 because 'design', 'select', and 'integrate' are few in number and fairly generic rather than several specific actions, and not a 2 because it does go beyond naming the domain to state what the framework does.

Completeness

It explicitly answers both: what ('Design multi-cloud architectures using a decision framework to select and integrate services across AWS, Azure, GCP, and OCI') and when ('Use when building multi-cloud systems, avoiding vendor lock-in, or leveraging best-of-breed services from multiple providers') with concrete trigger phrases. Not a 4 because the 'when' clause is already explicit and lists three concrete scenarios rather than being weakly implied.

Trigger Term Quality

Natural phrases users would say are present: 'building multi-cloud systems', 'avoiding vendor lock-in', 'best-of-breed services', 'multiple providers', plus all four provider names — good keyword coverage with only a few natural terms missing. It is not a 5 because synonyms like 'cloud-agnostic', 'portable', or 'hybrid cloud' are absent, and not a 3 because common variations users actually say ('vendor lock-in', 'best-of-breed') are covered.

Distinctiveness Conflict Risk

It occupies a clear niche (multi-cloud architecture across four named providers) with distinct triggers, giving minimal conflict risk with unrelated skills. Not a 5 because it can overlap with closely related skills the body itself lists (terraform-module-library, cost-optimization, hybrid-cloud-networking), e.g. a request to 'optimize costs across providers' could plausibly route to a cost-optimization skill.
