+Task:
+Classify the report for:

+- likelihood of AI-generated text
+
+Return STRICT JSON with exactly these keys:
+- low_signal_score: number from 0 to 1
+- ai_generated_likelihood: number from 0 to 1

+- labels: array of labels from this allowed set:
+ ["triage:needs-info","triage:low-signal","triage:suspected-ai"]
+- comment: a friendly maintainer comment asking for missing info (or empty string if not needed)
+
+Guidelines:
+- Prefer "triage:needs-info" when reproduction/environment details are missing.
+- Use "triage:low-signal" when the text is generic, contradictory, or lacks actionable specifics.
+- Use "triage:suspected-ai" only when strong indicators exist; never accuse; keep tone neutral.
+- If you produce a comment, include a short checklist:
+ version/commit, environment, repro steps, expected vs actual, logs/stacktrace, minimal repro.
+- Keep comment concise and polite.
