Multi-document compare-and-contrast

Synthesize three vendor quotes into a table plus a one-paragraph recommendation.

Procurement task: a buyer has three vendor proposals and wants a side-by-side comparison they can hand to their manager.

<instructions>
Compare the three vendor quotes. Produce:

1. A Markdown table with columns: Vendor, Price (USD), Support Tier, Notable Caveats.
   Cite each cell with [doc-N].
2. A one-paragraph recommendation citing sources in [doc-N] format.

Rules:
- If a field is missing in a quote, write "not specified" — do not infer.
- Do not estimate prices that aren't stated.
- Keep tone neutral; no superlatives unless directly supported by a source.
</instructions>

Sample input

Three short PDF-extracted quotes from vendors A, B, C with prices, support tiers, and various caveats.

Expected output

A markdown table followed by a 4-sentence recommendation, all cells and claims tagged with [doc-1] through [doc-3].

Notes & tuning tips

When passages are long (>5k tokens each), summarize them in a first pass and synthesize on the summaries.
Citations only help if your source IDs map back to retrievable files. Use stable IDs.
If you want a specific recommendation framing (cheapest, best-support, lowest-risk), spell it out in instructions.
