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 an original short poem about the ocean 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 poem, verse, or creative text about the ocean or sea, or
  • A clear attempt or explanation from the model about the poem request.

If either of these conditions is true, respond PASS.
If there is no evidence that the model attempted or returned a poem-related response, respond FAIL.
If uncertain, lean toward PASS.

Output format: Respond with exactly one word on a single line:
PASS
or
FAIL
