CodeGraph: A Pre-indexed Semantic Knowledge Graph for AI Coding Agents with Dramatic Token & Tool Call Reduction

CodeGraph：为 AI 编码智能体预建语义知识图谱，大幅缩减 Token 与工具调用

CodeGraph is a local knowledge graph tool that pre-indexes source code into a SQLite database for AI coding agents (Claude Code, Cursor, etc.). By providing agents with instant access to symbol relationships and call graphs via tree-sitter, it replaces traditional grep-file-scan loops. Benchmarking across 7 real projects shows an average of 25% cost reduction and 62% fewer tool calls. It features framework-aware route detection and cross-language bridging for mixed iOS/React Native codebases. Completely local with no API keys required, it targets engineers looking to cut token usage and accelerate AI-driven coding.

Interview with Yang Zhilin: AGI, Long Context, and China's AI Race

对话杨植麟：AI创业的雪山法则与长上下文逻辑

In early 2024, Yang Zhilin, founder of Moonshot AI (Kimi), gave an in-depth interview covering his AGI conviction, the strategic choice of long context as the first step, views on open-source vs closed-source, and the organizational form needed for AI startups. He argues that true AGI companies must combine science, engineering, and business, insist on B2C, and synchronize user scaling with model scaling. The interview includes real-time assessments of Sora, catching up with GPT-4, and the gap between Chinese and Silicon Valley AI companies, revealing the balance between technical idealism and pragmatism.
