Conciseness

Lean body with a tight decision matrix and minimal prose; assumes Claude's competence without explaining what Exa is or how caching works, so every token earns its place.

Actionability

Three complete, executable TypeScript examples using real SDK methods (searchAndContents, findSimilarAndContents, answer) with specific parameters and a decision matrix to pick one — copy-paste ready.

Workflow Clarity

Variant 3's RAG pipeline is explicitly sequenced into labeled phases (gather, expand, format, answer); operations are read-only so no validation checkpoint is required, matching the score-3 anchor for clear sequencing.

Progressive Disclosure

No bundle files exist, but the body is well-organized into clear navigable sections and signals a one-level reference (exa-reference-architecture skill) in Next Steps, satisfying the rubric's allowance for well-organized single-file skills.

Specificity

Lists multiple concrete actions ('Choose and implement') plus three named variants (direct search, cached search, RAG pipeline), matching the score-3 anchor for multiple specific concrete actions.

Completeness

Explicitly states what ('Choose and implement Exa architecture patterns...') and when ('Use when designing Exa integrations... or planning architecture for different traffic volumes') with explicit trigger phrases.

Trigger Term Quality

Trigger phrases like 'exa architecture', 'exa blueprint', 'exa at scale' skew toward developer jargon and miss common natural variations a user would actually say (e.g. 'exa search', 'exa caching').

Distinctiveness Conflict Risk

Scoped tightly to Exa architecture with niche-specific triggers ('exa blueprint', 'exa RAG design'), making it unlikely to fire for unrelated skills.
