${var} — Topic to research (required). Append --quick for a lighter pass (≤15 sources), or --days=N to change the lookback window (default: 30).

Google aggregates editors. A flat "top N posts per platform" aggregates noise. This skill does two things differently: (1) reframes output around narratives (clusters the same story across platforms) instead of platform-siloed recaps, and (2) makes the disagreement between platforms the primary signal — where Reddit is bearish and X is bullish on the same story, that divergence is usually the most actionable finding.

If ${var} is empty, abort and notify: "last30 requires var= set to a topic". Exit.

Steps

0. Parse parameters and bootstrap

Extract from ${var}:

topic: everything before any -- flags, trimmed
--quick: lighter mode (fewer sources, shorter report)
--days=N: custom lookback window (default: 30)
