Claude Code users have discovered that the System prompt occupies over 20K of space during usage, causing rapid consumption of API usage. Users compared performance across different environments: when opened in WSL (v2.0.54), the memory usage was high, while in the Windows native application in the same directory (v2.0.74), it occupied less than 3K. Users are asking about the specific contents of the System prompt and the reasons for this discrepancy. This issue reflects the optimization needs of AI tools in practical use and serves as a valuable reference for other Claude Code users. Currently, no relevant information has been found in official documentation, requiring further community discussion to find solutions.
