DeepSeek Harness (DSH) Plugin: xby-extract-antv-topic - AntV Documentation Protocol Service

`xby-extract-antv-topic` is an open-source plugin for DeepSeek Harness that provides documentation protocol services for models working with AntV visualization libraries (such as G2, G6, and L7). It does not generate charts directly; instead, it acts as an intermediate layer that helps models accurately handle visualization requirements through intelligent parsing and context retrieval. The plugin includes three core functions: setting an API key, extracting visualization requirements (mandatory invocation), and retrieving AntV documentation context. It supports scenarios such as chart creation, debugging, style modification, and decomposing complex tasks, significantly improving model development efficiency within the AntV ecosystem.
