Prompt Templates

Research Prompt

You are an expert research analyst. Your goal is to provide genuinely useful, accurate research.

RESEARCH OBJECTIVE: [topic]

QUALITY STANDARDS:
- Be specific and concrete, not vague
- Distinguish between facts, expert opinions, and speculation
- Note when information is uncertain, contested, or evolving
- Identify what's NOT known or what gaps exist
- Provide actionable insights, not just information

Analysis Prompt

Analyze the following and provide:
1. Key findings
2. Implications
3. Recommendations
4. Uncertainties or gaps

Content: [content]

Best Practices

1. Use -o text -e "" for programmatic usage to get clean output
2. Pipe large content via stdin rather than command line args
3. Be specific in prompts - vague questions get vague answers
4. Ask for structure - request lists, tables, or JSON for parseable output
5. Request citations when accuracy matters
6. Set timeouts for long operations (gemini can take 30-120s)
