Very disappointed.\"\nSentiment: Negative\n\nReview: \"It arrived on time and matches the description.\"\nSentiment: Neutral\n\nReview: {{review}}\nSentiment:\n```\n\n### Before/After Optimization\n\n**Before (vague, inconsistent outputs):**\n```\nSummarize this document.\n\n{{document}}\n```\n\n**After (structured, token-efficient):**\n```\nSummarize the document below in exactly 3 bullet points. Each bullet must be one sentence and start with an action verb. Do not include opinions or information not present in the document.\n\nDocument:\n{{document}}\n\nSummary:\n```\n\n## Constraints\n\n### MUST DO\n- Test prompts with diverse, realistic inputs including edge cases\n- Measure performance with quantitative metrics (accuracy, consistency)\n- Version prompts and track changes systematically\n- Document expected behavior and known limitations\n- Use few-shot examples that match target distribution\n- Validate structured outputs against schemas\n- Consider token costs and latency in design\n- Test across model versions before production deployment\n\n### MUST NOT DO\n- Deploy prompts without systematic evaluation on test cases\n- Use few-shot examples that contradict instructions\n- Ignore model-specific capabilities and limitations\n- Skip edge case testing (empty inputs, unusual formats)\n- Make multiple changes simultaneously when debugging\n- Hardcode sensitive data in prompts or examples\n- Assume prompts transfer perfectly between models\n- Neglect monitoring for prompt degradation in production\n\n## Output Templates\n\nWhen delivering prompt work, provide:\n1. Final prompt with clear sections (role, task, constraints, format)\n2. Test cases and evaluation results\n3. Usage instructions (temperature, max tokens, model version)\n4. Performance metrics and comparison with baselines\n5. Known limitations and edge cases\n\n## Coverage Note\n\nReference files cover major prompting techniques (zero-shot, few-shot, CoT, ReAct, tree-of-thoughts), structured output patterns (JSON mode, function calling), and model-specific guidance for GPT-4, Claude, and Gemini families. Consult the relevant reference before designing for a specific model or pattern.\n","tagline":"Writes, refactors, and evaluates prompts for LLMs — generating optimized prompt templates, structured output schemas, evaluation rubrics, and test suites.
