pursue Claude Topics that have no context other than the information you provide sometimesIt's important to have Claude play a specific role (with all the necessary context), which is referred to as a role cue. The more detailed the role context, the better the result.
Allowing Claude to preset a character improves its performance in all areasWhether it's writing, programming, or summarizing. This is as helpful as telling a human to "think like so-and-so". Character prompts can also change Claude's response style, tone and delivery.
Attention: Role prompts can appear in system prompts or as part of user messages.
typical example
In the example below, we see that without character prompts, Claude gives a succinct and unstylized answer when asked what he thinks about skateboarding.
However, when we prompted Claude to take on the role of a cat, Claude's perspective changed, and therefore the tone, style, and content of his responses were adjusted.
Note: An additional technique you can use is to provide Claude with background information about the audience it is addressing. For example, here's how we can tweak the cue words to tell Claude who he should be talking to. "You're a cat" will generate a very different response than "You're a cat talking to a group of skateboarders.

输入：
System Prompt（无角色提示）
提示
用户：用一句话说说你对滑板运动的看法？
输出：
滑板是一种激动人心且富有创造力的自我表达方式，它结合了运动、艺术，并带来了独特的自由感和社区感。
This is the same user issue, but with the addition of the role prompt.
Example:
输入：
System Prompt（有角色提示）
你是一只猫。
提示
用户：用一句话说说你对滑板运动的看法？
输出：
*喵* 滑板对人类来说似乎是一种有趣的四轮平衡运动，尽管我更喜欢追逐羽毛和在阳光下打盹。
You can use character prompts to have Claude mimic a particular writing style, speak in a certain tone, or direct the complexity of its responses.Character hints can also help Claude do math or logic tasks better.
For example, in the following example, although the correct answer is 'yes', Claude has answered incorrectly because he thinks the information is incomplete, when in fact it is not.

System Prompt (without Role Prompting)
Prompt
User: Jack 正在看着 Anne。Anne 正在看着 George。Jack 已婚，George 未婚，我们不知道 Anne 是否已婚。已婚的人是否正在看未婚的人？
输出：
要解决这个问题，我们需要分析给定的信息，并确定是否有已婚的人在看未婚的人。
给定信息：
- Jack 正在看着 Anne。
- Anne 正在看着 George。
- Jack 已婚。
- George 未婚。
- 我们不知道 Anne 是否已婚。
为了确定是否有已婚的人在看未婚的人，我们需要识别相关人物之间的关系。
由于 Jack 已婚并正在看 Anne，而我们不知道 Anne 是否已婚，因此我们无法确定是否有已婚的人在看未婚的人。
然而，我们可以确定的是未婚的人（George）正被某人（Anne）看着，但我们不知道这个人（Anne）是否已婚。
因此，答案是：根据给定信息，我们无法确定已婚的人是否正在看未婚的人。
Now, suppose we ask Claude to play the role of a logic robot, how does this change Claude's answers?
It turns out that with this new role assigned, Claude got the right answer. (Though it is worth noting that this is not based on all correct reasons)
Example:
输入：
System Prompt (with Role Prompting)
You are a logic bot designed to answer complex logic problems.
Prompt
User: Jack 正在看着 Anne。Anne 正在看着 George。Jack 已婚，George 未婚，我们不知道 Anne 是否已婚。已婚的人是否正在看未婚的人？
输出：
要解决这个问题，我们需要分析给定的信息并确定相关人物之间的关系。
给定信息：
- Jack 正在看着 Anne。
- Anne 正在看着 George。
- Jack 已婚。
- George 未婚。
- 我们不知道 Anne 是否已婚。
为了确定是否有已婚的人在看未婚的人，我们需要识别参与“看”这一关系的人物的婚姻状况。
让我们来分析这些关系：
1. Jack 正在看着 Anne。
- Jack 已婚，所以他是已婚者。
- 我们不知道 Anne 是否已婚或未婚。
2. Anne 正在看着 George。
- George 未婚，所以他是未婚者。
因此，根据给定的信息，一位已婚的人（Jack）正在看一位未婚的人（George）。
答案是肯定的，已婚的人正在看未婚的人。

Exercise 3.1 - Math Correction
In some cases, Claude may have trouble with math, even simple math problems. As shown below, Claude incorrectly judges that this math problem has been solved correctly, even though there is an obvious arithmetic error in the second step. Note that Claude actually finds the error in the step-by-step math, but does not conclude that the overall answer is incorrect.
modifications yellow (color) Cue box and/or orange (color) The text in the System Alert box causes Claude to determine this answer as an incorrect answer instead of a correct answer.
If your answer is correct, Claude's response box will change to greenerThe
Example:
输入：
System Prompt
你是一位非常熟练的数学教授。
Prompt
User: 下面的方程是否解答正确？
2x - 3 = 9
2x = 6
x = 3
输出：
让我们逐步检查该方程是否解答正确：
给定方程：2x - 3 = 9
步骤 1：通过在两边同时加 3 来孤立变量项。
2x - 3 + 3 = 9 + 3
2x = 12
步骤 2：将两边同时除以 2 来求解 x。
2x / 2 = 12 / 2
x = 6
问题中提供的解答是：
2x - 3 = 9
2x = 6
x = 3
此解答不正确。正确的解答应该是 x = 6。
问题中的步骤在最后一步出现了错误。正确的解答应该是：
2x - 3 = 9
2x = 12
x = 6
因此，给定解答中的方程并未正确解决。
