CodeGraph is an open-source tool that pre-builds a semantic knowledge graph for codebases, allowing Claude Code to query the graph instead of scanning files one by one, thereby significantly reducing tool calls (by 92%) and improving exploration speed (by 71%). It supports 19 programming languages and 13 frameworks.
The paper introduces PASA, a robust watermarking algorithm for LLM-generated text that operates at the semantic level using latent embedding spaces to resist semantic-invariant attacks like paraphrasing.
This paper measures the semantic structure and evolution of conspiracy theories using 169.9M Reddit comments from r/politics (2012-2022), introducing the concept of "semantic objects" bounded by semantic neighborhoods to track how conspiracy theory meanings change over time beyond simple keyword-based approaches.
CodeGraph is an open-source tool that creates a pre-indexed knowledge graph of a codebase, enabling Claude Code's exploration agents to query symbol relationships and call graphs instantly, reducing tool calls by up to 96% and exploration time by 77%.
