dependency-chain

在删除文件或更改签名之前，追踪依赖关系链。构建依赖图，检测循环依赖，列出可能引发断裂的节点。在删除文件、更改函数签名、修改数据库模式，或当用户说“移除”或“删除”时使用此功能。

description: Traces dependency chains before deleting files or changing signatures. Builds dependency graph, detects circular dependencies, lists breaking points. Use when deleting files, changing function signatures, modifying database schema, or when user says "remove" or "delete".

Dependency Chain Analyzer

When to Trigger

  • •When deleting any file
  • •When changing function signatures
  • •When modifying database schema
  • •When user says "remove" or "delete"

What to Do

Step 1: Build Dependency Graph

Trace the chain:

code
File/Function to Change
  ↓ imported by
Component A
  ↓ used in
Page X
  ↓ linked from
Navigation Menu
  ↓ accessed by
User Role: Admin, Manager

Step 2: Check for Circular Dependencies

Detect and warn about:

  • •A imports B, B imports A
  • •Component recursion
  • •Infinite loops in data fetching

Step 3: List All Breaking Points

Output:

markdown
## Dependency Chain for [item]

### Direct Dependencies (files that import this):
1. file1.ts - line 12 (imports function X)
2. file2.tsx - line 45 (uses component Y)

### Indirect Dependencies (affected downstream):
1. Page: /admin/bookings (uses file1.ts)
2. API: /api/bookings (calls this function)
3. Component: BookingCard (renders this data)

### User-Facing Impact:
- ⚠️ Bookings page will break
- ⚠️ Dashboard widget will show errors

### Safe Deletion Checklist:
- [ ] Remove from file1.ts imports
- [ ] Update file2.tsx to use alternative
- [ ] Add migration for database changes
- [ ] Update tests
- [ ] Deploy in this order: [list order]

If critical dependencies exist, state: CANNOT DELETE SAFELY and recommend migration plan (create replacement, migrate callers, deprecate, then delete).
