LLM 提示

基本结构

[角色/上下文] + [任务] + [约束] + [输出格式]

角色提示

infsh app run openrouter/claude-sonnet-45 --input '{
  "prompt": "You are an expert data scientist with 15 years of experience in machine learning. Explain gradient descent to a beginner, using simple analogies."
}'

任务清晰度

# 差：模糊
"Help me with my code"

# 好：具体
"Debug this Python function that should return the sum of even numbers from a list, but returns 0 for all inputs:

def sum_evens(numbers):
    total = 0
    for n in numbers:
        if n % 2 == 0:
            total += n
        return total

Identify the bug and provide the corrected code."

思维链（Chain-of-Thought）

infsh app run openrouter/claude-sonnet-45 --input '{
  "prompt": "Solve this step by step:\n\nA store sells apples for $2 each and oranges for $3 each. If someone buys 5 fruits and spends $12, how many of each fruit did they buy?\n\nThink through this step by step before giving the final answer."
}'

少样本示例（Few-Shot）

infsh app run openrouter/claude-sonnet-45 --input '{
  "prompt": "Convert these sentences to formal business English:\n\nExample 1:\nInput: gonna send u the report tmrw\nOutput: I will send you the report tomorrow.\n\nExample 2:\nInput: cant make the meeting, something came up\nOutput: I apologize, but I will be unable to attend the meeting due to an unforeseen circumstance.\n\nNow convert:\nInput: hey can we push the deadline back a bit?"
}'

输出格式规范

infsh app run openrouter/claude-sonnet-45 --input '{
  "prompt": "Analyze the sentiment of these customer reviews. Return a JSON array with objects containing \"text\", \"sentiment\" (positive/negative/neutral), and \"confidence\" (0-1).\n\nReviews:\n1. \"Great product, fast shipping!\"\n2. \"Meh, its okay I guess\"\n3. \"Worst purchase ever, total waste of money\"\n\nReturn only valid JSON, no explanation."
}'

约束设置

infsh app run openrouter/claude-sonnet-45 --input '{
  "prompt": "Summarize this article in exactly 3 bullet points. Each bullet must be under 20 words. Focus only on actionable insights, not background information.\n\n[article text]"
}'

图像生成提示

基本结构

[主体] + [风格] + [构图] + [光线] + [技术参数]

质量关键词

photorealistic, 8K, ultra detailed, sharp focus, professional,
masterpiece, high quality, best quality, intricate details

高级技术

系统提示

infsh app run openrouter/claude-sonnet-45 --input '{
  "system": "You are a helpful coding assistant. Always provide code with comments. If you are unsure about something, say so rather than guessing.",
  "prompt": "Write a Python function to validate email addresses using regex."
}'

迭代优化

# 从宽泛开始
# 添加具体细节
# 添加风格
# 添加技术参数

多轮推理

# 第一轮：分析
# 第二轮：优先级排序
# 第三轮：行动计划

模型特定技巧

Claude

• 擅长细微指令
• 对角色扮演响应良好
• 善于遵循复杂约束
• 偏好明确的输出格式

GPT-4

• 代码生成能力强
• 示例效果良好
• 结构化输出好
• 响应 "let's think step by step"

常见错误

错误	问题	修复
太模糊	不可预测的输出	添加具体细节
太长	模型失去焦点	优先处理关键信息
矛盾	模型困惑	移除矛盾
无格式	输出不一致	指定格式
无示例	期望不明确	添加少样本
