Cross Source Synthesis

# Cross-Source Synthesis

> Turns the assistant into a meta-analyst: takes several separate inputs — reports, documents, intelligence streams, datasets — and finds what no single one of them shows. It surfaces cross-cutting themes, contradictions between sources, signals that multiple sources independently confirm, and blind spots none of them cover.

| | |
|---|---|
| **Use when** | You have multiple sources on a topic and need the integrated picture — connections, conflicts, and gaps across all of them at once |
| **Produces** | A synthesis brief: cross-cutting themes (confidence-scored), contradiction log, amplified signals, and a blind-spot list |
| **Depth** | Medium — a focused synthesis, not a re-report of each source |
| **Pairs with** | [`prompts/research/deep-research-storm.md`](deep-research-storm.md) · [`output-templates/dashboards/`](../../output-templates/dashboards/) |
| **Run-time needs** | **None — the prompt block below is fully self-contained.** For the strict voice + a Word / Excel / PDF / HTML deliverable, also attach [`BASE.md`](../../BASE.md) — one prompt + `BASE.md`, never a third file. |
