AstAnalysis

基于 AST 的 JS/TS 代码查询。当你需要查找代码模式、获取函数调用、列出事件监听器、提取导入内容，或对 AST 进行查询时，请使用此功能。

AstAnalysis

Query JavaScript/TypeScript code using AST parsing. Dynamically generates and runs custom parser code for any pattern you describe.

How It Works

  1. •Clarify (skippable): AI asks clarifying questions to understand exactly what you need
  2. •Generate: AI creates custom TypeScript AST traversal code for your specific query
  3. •Execute: Runs the generated code against your files/directories
  4. •Report: Returns findings with file:line - code format

The AI generates fresh AST parsing code for each request, so you can query for any pattern - not limited to predefined queries.

Examples

Example 1: Find postMessage listeners

code
User: "Find all postMessage listeners in src/"
→ AI clarifies: event types? include iframes? (user can skip)
→ Returns file:line for each match

Example 2: Get function calls

code
User: "List all fetch() calls in ./api"
→ AI clarifies: include axios/got? async only? (user can skip)
→ Returns locations and call details

Example 3: Extract values

code
User: "Find strings starting with 'sk-' in config/"
→ AI clarifies: variable assignments only? include template literals? (user can skip)
→ Returns matches with locations
