Use whenever an AI agent executes a multi-step task to save tokens, parallelize tool calls, cache prompts, and keep replies under 2000 chars
Use when creating or developing, before writing code or implementation plans - refines rough ideas into fully-formed designs through collaborative questioning, alternative exploration, and incremental validation. Don't use during clear 'mechanical' processes
Bug 修复全流程。强制 /investigate 找根因，禁止"看似修好就交付"。/freeze 锁定文件 防止顺手"清理"无关代码；先写复现失败测试再写修复。 Use when reporting bugs, errors, 500s, stack traces, or "it stopped working" type issues. Voice triggers: "修 bug", "/bugfix-flow", "bugfix".
开发组合拳总入口。根据输入形式（需求文档 / 原型项目 / 一句话）× 开发范围（前端 / 后端 / 全栈） × 修饰符（带设计稿 / 数据库迁移 / 只联调 等）自动路由到正确的子 skill。同时覆盖 4 类非需求任务： bugfix / 重构 / 性能优化 / 第三方接入。 Use when asked to "接需求", "开始开发", "/dev-flow", "组合拳", "dev flow", or whenever the user hands over a development task and you need to decide which workflow skill to invoke. Voice triggers: "接需求", "开始开发", "组合拳". Note: 阶段切片型 skills（/dev-understand、/dev-implement、/dev-ship-retro）按阶段拆分， 与本路由按场景类型拆分的子 skill 互补；当用户明确说"只做某阶段"时优先匹配那些 skill。
Use when partner provides a complete implementation plan to execute in controlled batches with review checkpoints - loads plan, reviews critically, executes tasks in batches, reports for review between batches
性能优化全流程。先 benchmark 立基线 → profile 找瓶颈 → 单一变量优化 → 再 benchmark 对比。禁止"凭感觉优化"，每个改动必须带数据证明。 Use when optimizing for performance, page speed, web vitals, or backend latency. Voice triggers: "性能优化", "/perf-flow", "提速".
代码重构 / 整理。任何重构必须先有覆盖待重构区域的测试网；分步原子 commit；每步 绿测，不允许"大爆炸式重构"。性能/行为变更属于 perf-flow / dev-flow，不在此范围。 Use when refactoring code, cleaning up tech debt, or restructuring without behavior change. Voice triggers: "重构", "整理代码", "/refactor-flow".
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes - four-phase framework (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures understanding before attempting solutions
