Entry Points

入口点

Functions matching entry patterns are excluded from dead code analysis:
  • main
    , 
    cli
    - Application entry points
  • test_*
    , 
    *_test
    - Test functions
  • setup
    , 
    teardown
    - Fixtures
  • @app.route
    , 
    @api.endpoint
    - Framework handlers
bash
undefined
匹配入口点模式的函数将被排除在死代码分析之外：
  • main
    , 
    cli
    - 应用程序入口点
  • test_*
    , 
    *_test
    - 测试函数
  • setup
    , 
    teardown
    - 测试夹具
  • @app.route
    , 
    @api.endpoint
    - 框架处理器

Integration

集成方式

This skill replaces the session-start-dead-code hook with on-demand analysis.
ApproachProsCons
Hook (removed)AutomaticSlowed startup by 3s
Skill (this)On-demand, fastManual invocation
本技能将session-start-dead-code钩子替换为按需分析。
实现方式优点缺点
钩子（已移除）自动执行启动速度减慢3秒
本技能按需执行、速度快需手动调用
