12 Ways to Cut Token Consumption in Claude Code

Token efficiency in Claude Code has become a significant concern among developers due to the high volume of tokens consumed in sessions, as seen in a viral Reddit post where one user reported using over a billion tokens in a month. The inefficiency arises from a fixed overhead of 20,000-30,000 tokens in the context window before typing begins, as well as from processing unnecessary data like raw HTML and system prompts. To address this, developers are encouraged to use strategies such as feeding clean web data, trimming CLAUDE.md files to under 500 tokens, and employing both .claudeignore and permissions.deny for context discipline. Additionally, moving rules to path-scoped directories, filtering tool output, and using precise prompts can significantly reduce token usage. It is also vital to control MCP server overhead and match the model to the task, using lightweight models like Haiku for less complex tasks, thereby achieving up to 75% cost reduction. Commands like /compact, /clear, and /rewind help manage context size, and integrating skills allows for progressive disclosure of capabilities. These techniques not only optimize costs but also enhance output quality by minimizing context noise, ensuring Claude Code performs efficiently without compromising on the quality of results.
