DeepSeek Prompt Library
Unlock the reasoning power of DeepSeek V3 & R1 with these curated developer prompts.
For Software Developers & Engineers
The Strategy: Debugging
Stop pasting just the error. This prompt forces the AI to act like a Senior Dev—explaining the core “Why” before fixing the “What.”
“Analyze the following Python code for logical errors and possible edge cases that could cause a runtime crash. Do not just fix the syntax; explain the root cause of the bug and provide a refactored version that follows PEP 8 standards.”
The Strategy: Unit Testing
Writing tests is boring but necessary. This prompt saves hours by generating a complete test suite with “mocked” data.
“Write a comprehensive pytest test suite for the function below. Include test cases for: 1. Happy path (normal data), 2. Edge cases (null/empty inputs), and 3. Error handling. Mock any external API calls using ‘unittest.mock’.”
The Strategy: Refactoring
Use this when you inherit “spaghetti code” that is impossible to read. It forces the AI to clearly document and simplify complex logic.
“Refactor this legacy code to make it more readable and more efficient. Add docstrings to every function explaining inputs/outputs, rename variables to be descriptive, and reduce the complexity of nested loops. Maintain the original functionality.”
