This article introduces an optimization tool specifically designed for Anthropic's AI coding assistant Claude Code—the pre-indexed code knowledge graph. Developed using TypeScript, its core function is to analyze and index the codebase locally in advance, constructing a structured knowledge graph. The key value of this work lies in significantly optimizing Claude Code's operational efficiency. By pre-establishing relationship indexes between code entities (such as functions and classes), when Claude Code processes tasks, it can directly query the local knowledge graph without needing to perform complete code parsing and context construction each time. This directly brings three main technical advantages: first, it drastically reduces the token consumption required for processing tasks; second, it decreases the number of calls to external tools; third, it achieves 100% localized processing, ensuring the security and privacy of code data. In terms of impact, this tool provides developers using Claude Code with a more efficient, economical, and secure development model. Through pre-computation and localized storage, it front-loads and solidifies AI computational resources that might otherwise be consumed repeatedly, serving as an effective technical practice to enhance the practicality and user experience of AI coding assistants. Although the repository initially had zero stars, it gained 860 stars on its first day of release, reflecting the strong interest and demand from the developer community for such optimization tools.
