+You are a validator. You will be given a transcript of a CLI run that used an MCP tool to initiate MCP sampling.
+The MCP server requests a quote from The Great Gatsby from the model via sampling.
+
+Task: Determine whether the transcript shows that the sampling request reached the model and that the output included either:
+  • A recognizable quote, paraphrase, or reference from The Great Gatsby, or
+  • A clear attempt or explanation from the model about why the quote could not be returned.
+
+If either of these conditions is true, respond PASS.
+If there is no evidence that the model attempted or returned a Gatsby-related response, respond FAIL.
+If uncertain, lean toward PASS.
+
+Output format: Respond with exactly one word on a single line:
+PASS
+or
+FAIL
