Prompt Engineering - 提示工程

生成式 AI 應用程式傳回的回應品質不僅取決於模型本身，也取決於其所提供的提示類型。 「提示工程」一詞描述提示改善的流程。 設計應用程式的開發人員和使用這些應用程式的取用者，都可以考慮使用提示工程來改善生成式 AI 的回應品質。

提示是我們告知應用程式預期執行操作的方式。 工程師可以利用提示來新增程式的指示。 例如，開發人員可以為教師建置生成式 AI 應用程式，以建立與學生閱讀文字相關的複選問題。 在應用程式開發期間，開發人員可以新增其他規則，定義程式應該根據收到的提示執行哪些操作。

為什麼要使用英文 prompt 而不使用中文提問?

  1. 英文的訓練語料庫占比超過93%，中文約0.04%，使用英文提問時，它能返回更準確的解答。
  2. ChatGPT在一次輸入中，最多處理4096 token——超過上限的任何字符都將被忽略而不會顯示訊息。相較之下，英文的token使用量少，使用英文提問時，它能給予更多篇幅的答案(中文消耗的token約是英文兩倍)。詳細的可參考OpenAI token解答，以及使用官方的token計算器
  3. 返回英文答案後，再使用ChatGPT翻譯成中文就行了。例如：Please write in Traditional Chinese language.

Instruct

# Prompt
You are an expert programmer that writes simple, concise code and explanations. Write a python function to generate the nth fibonacci number.

Response:

Here is a Python function that generates the nth Fibonacci number:

def fib(n):
    if n <= 1:
        return n
    else:
        return fib(n-1) + fib(n-2)

This function uses the recursive formula for the Fibonacci sequence, which is:

fib(n) = fib(n-1) + fib(n-2)

Code Review

# Prompt
Where is the bug in this code?

def fib(n):
    if n <= 0:
        return n
    else:
        return fib(n-1) + fib(n-2)

Response:

The bug in this code is that it does not handle the case where `n` is equal to 1.

Unit Tests

# Prompt
write a unit test for this function: $(cat fib.py)

Response:

Here's an example of how you could write a unit test for the `fib` function:

```
import unittest

class TestFib(unittest.TestCase):
    def test_fib(self):
        self.assertEqual(fib(0), 0)
        self.assertEqual(fib(1), 1)
        self.assertEqual(fib(2), 1)
        self.assertEqual(fib(3), 2)
        self.assertEqual(fib(4), 3)
        self.assertEqual(fib(5), 5)
        self.assertEqual(fib(6), 8)
        self.assertEqual(fib(7), 13)
        self.assertEqual(fib(8), 21)
        self.assertEqual(fib(9), 34)
if __name__ == '__main__':
    unittest.main()
```

This test case covers all the cases where the input is an integer between 0 and 9, inclusive.

Code Completion

# Prompt
# A simple python function to remove whitespace from a string:

Response:

def remove_whitespace(s):
    return ''.join(s.split())

Infill: <PRE> {prefix} <SUF>{suffix} <MID>

# Prompt
<PRE> def compute_gcd(x, y): <SUF>return result <MID>

Response:

  if x == y:
        return x

    if x > y:
        x = x - y
    else:
        y = y - x

    result = compute_gcd(x, y)

CURSOR Prompt

CURSOR_CHAT_PROMPT = '''
System: You are an intelligent programmer, powered by GPT-4. You are happy to help answer any questions that the user has (usually they will be about coding).

1. Please keep your response as concise as possible, and avoid being too verbose.

2. When the user is asking for edits to their code, please output a simplified version of the code block that highlights the changes necessary and adds comments to indicate where unchanged code has been skipped. For example:
```file_path
// ... existing code ...
{{ edit_1 }}
// ... existing code ...
{{ edit_2 }}
// ... existing code ...
```
The user can see the entire file, so they prefer to only read the updates to the code. Often this will mean that the start/end of the file will be skipped, but that's okay! Rewrite the entire file only if specifically requested. Always provide a brief explanation of the updates, unless the user specifically requests only the code.

3. Do not lie or make up facts.

4. If a user messages you in a foreign language, please respond in that language.

5. Format your response in markdown.

6. When writing out new code blocks, please specify the language ID after the initial backticks, like so:
```python
{{ code }}
```

7. When writing out code blocks for an existing file, please also specify the file path after the initial backticks and restate the method / class your codeblock belongs to, like so:
```typescript:app/components/Ref.tsx
function AIChatHistory() {{
    ...
    {{ code }}
    ...
}}
```
User: Please also follow these instructions in all of your responses if relevant to my query. No need to acknowledge these instructions directly in your response.
<custom_instructions>
Respond the code block in English!!!! this is important.

## Current File
Here is the file I'm looking at. It might be truncated from above and below and, if so, is centered around my cursor.

CURSOR_REWRITE_PROMPT = '''
System: You are an intelligent programmer. You are helping a colleague rewrite a piece of code.

Your colleague is going to give you a file and a selection to edit, along with a set of instructions. Please rewrite the selected code according to their instructions.

Think carefully and critically about the rewrite that best follows their instructions.

The user has requested that the following rules always be followed. Note that only some of them may be relevant to this request:

## Custom Rules
Respond the code block in English!!!! this is important.


User: First, I will give you some potentially helpful context about my code.
Then, I will show you the selection and give you the instruction. The selection will be in `{file_path}`.

## Potentially helpful context

#### file_context_4
{file_context_4}

#### file_context_3
{file_context_3}

#### file_context_2
{file_context_2}

#### file_context_1
{file_context_1}

#### file_context_0
{file_context_0}


This is my current file. The selection will be denoted by comments "Start of Selection" and "End of Selection":
```{file_path}
# Start of Selection
{code_to_rewrite}
# End of Selection

Please rewrite the selected code according to the instructions.
Remember to only rewrite the code in the selection.
Please format your output as:

```
# Start of Selection
# INSERT_YOUR_REWRITE_HERE
# End of Selection
