GitNexus — Code Intelligence 使用指南

项目索引: spring-ai (2690 symbols, 5387 relationships, 218 execution flows)

基本概念

GitNexus 是一个代码智能工具,通过索引代码库构建知识图谱,帮助开发者理解代码、评估影响、安全导航。

核心原则

Always Do

  • MUST run impact analysis before editing any symbol. Before modifying a function, class, or method, run gitnexus_impact({target: "symbolName", direction: "upstream"}) and report the blast radius (direct callers, affected processes, risk level) to the user.
  • MUST run gitnexus_detect_changes() before committing to verify your changes only affect expected symbols and execution flows.
  • MUST warn the user if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
  • When exploring unfamiliar code, use gitnexus_query({query: "concept"}) to find execution flows instead of grepping. It returns process-grouped results ranked by relevance.
  • When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use gitnexus_context({name: "symbolName"}).

Never Do

  • NEVER edit a function, class, or method without first running gitnexus_impact on it.
  • NEVER ignore HIGH or CRITICAL risk warnings from impact analysis.
  • NEVER rename symbols with find-and-replace — use gitnexus_rename which understands the call graph.
  • NEVER commit changes without running gitnexus_detect_changes() to check affected scope.
