Builds and queries code knowledge graph for dependency analysis, references, implementations, and architecture overview. Use when starting work on unfamiliar codebase or before refactoring.
默认使用会先检查来源的 Prompt；你也可以切换为直接命令，或下载本地副本。
决定是否安装前，请先阅读 SKILL.md，以及 SkillsMP 当前展示的配套文件。
用 Codex 或 Claude 帮你安装 复制这段 Prompt，粘贴到 Codex、Claude 或其他助手里，让它检查 Skill 页面并帮你完成安装。
直接命令不会经过审查 Prompt；运行前请先检查来源。
npx skills add https://github.com/majiayu000/claude-skill-registry --skill ln-020-codegraph命令会保持在同一行。复制前请横向滚动并检查完整内容。

Type: Standalone Utility Category: 0XX Dev Environment
Indexes codebase into a layered graph (tree-sitter AST → SQLite) and provides dependency analysis, path tracing, references, implementations, and architecture overview via MCP tools.
| Input | Required | Source | Description |
|---|---|---|---|
project_path | yes | args or CWD | Project root to index |

| no |
| args |
Specific action: index, search, symbol, paths, refs, arch |
index + architecturesearch + get_symbol + trace_pathstrace_pathssearchCheck if graph exists (.codegraph/index.db in project root).
If NOT exists:
Call: index_project({ path: "{project_path}" })
If exists (re-index on demand):
Call: index_project({ path: "{project_path}" })
Idempotent — skips unchanged files automatically.
Route based on user intent:

| "Who calls X?" / "What does X call?" | trace_paths | { name: "X", file: "...", path_kind: "calls", direction: "reverse"|"forward" } |
| "Tell me about X" / "Context of X" | get_symbol | { name: "X", file: "..." } |
| "Project structure" / "Architecture" | get_architecture | { path?: "src/" } |
| "Find symbol X" | search_symbols | { query: "X" } |
