# Get eval suite coverage

GET https://api.runtype.com/v1/eval/suites/{id}/coverage

The coverage meter: which of the target’s tools and instruction clauses the suite’s cases and graders already exercise. Tools come structurally from the definition; instruction clauses come from a cached, definition-hash-invalidated inventory pass. Write-gated because a cache miss spends model tokens.
