Needle-in-Megahaystack: 1M Token Retrieval Patterns

You are analyzing a document of approximately 1M tokens.

TASK: Find [specific information].

NAVIGATION:
- The document is organized into sections marked with "=== SECTION X: Title ==="
- [Topic] is likely to appear in sections discussing [hint 1], [hint 2]
- Look for the specific phrase "[exact phrase]" or variations like "[variation]"

OUTPUT FORMAT:
If FOUND:
- Quote the exact passage (3 sentences of surrounding context)
- Section reference: "Found in Section X: [title]"
- Confidence: HIGH (exact match) / MEDIUM (inferred)

If NOT FOUND:
- List every section you checked
- State: "Confirmed absent from [N] of [N] sections checked"

If MULTIPLE mentions:
- List all instances with section references and context

ANSWER this question by finding and combining information from MULTIPLE
locations in the 1M token document:

QUESTION: [requires information from 2+ locations]

STEP 1: Find information about [Topic A]
- Location found: [section, approximate position]
- Content found: [quote or summary]

STEP 2: Find information about [Topic B]
- Location found: [section, approximate position]
- Content found: [quote or summary]

STEP 3: SYNTHESIS
- Combine finding 1 and finding 2 to answer the question
- If findings contradict: explain the contradiction, don't pick one
- Identify any missing information that prevents a complete answer

I'm loading 50 legal contracts totaling ~800K tokens.

QUESTION: Across all contracts, which supplier has the most favorable termination
clause for the buyer?

APPROACH:
1. Scan all contracts for "Termination" sections
2. Extract termination notice period and penalty clauses from each
3. Compare across contracts
4. Identify which supplier offers: shortest notice period, lowest/no penalty, most buyer-friendly terms

OUTPUT:
| Supplier | Notice Period | Penalty | Overall Favorability |
|---|---|---|---|
| [Name]    | 30 days       | None    | Most favorable        |
| [Name]    | 90 days       | 25%     | Least favorable       |

PASS 1 (broad scan):
"Scan the 800K token document for ANY mention of [topic].
List ALL mentions with approximate section locations."

PASS 2 (verify accuracy):
"For each mention from Pass 1, quote the exact passage verbatim
(with 3 sentences of surrounding context)."

PASS 3 (challenge findings):
"For each quoted passage, argue AGAINST the interpretation that it means
[presumed meaning]. What alternative interpretations are possible?"

PASS 4 (final answer):
"Based on all three passes, provide your conclusion with confidence levels."

TASK: Confirm whether [specific clause type] exists in these 200 contracts.

APPROACH:
1. For EACH contract, state: "Contract [Name] — [FOUND / NOT FOUND]"
2. If FOUND: quote the clause with section reference
3. If NOT FOUND: list the sections you checked

FINAL SUMMARY:
- Contracts with clause: [list with references]
- Contracts without clause: [list, confirmed absent]
- Contracts ambiguous: [list, with explanation]

This is a negative finding task. Absence of the clause is a valid answer.
Do NOT fabricate clauses for contracts where they don't exist.

=== CONTRACT #14: Acme Corp — Termination Clause ===

14.1 Notice Period: Either party may terminate this Agreement upon
ninety (90) days written notice.

14.2 Breach: In the event of material breach, the non-breaching party
may terminate immediately upon written notice, provided the breaching
party fails to cure within thirty (30) days.

14.3 Penalty: Early termination by Customer shall incur a penalty equal
to twenty-five percent (25%) of the remaining contract value.

=== END CONTRACT #14 ===

Also there's some stuff about ending the contract. I think it's 90 days
or maybe 30 if there's a problem. There might be a penalty too, probably
around 25% but you'd need to check.
