 # Bulk Refactor Workflow（批量重构 / 大范围修改）
 
 ## When to Use
+
 - Rename API / symbol / file convention across many files
 - Mechanical refactors (imports, formatting, lint fixes, signature migrations)
 - Cross-cutting changes touching 10+ files
 
 ## Inputs（required）
+
 - Scope：目录/文件类型/排除项（include/exclude）
 - Transformation：要做的规则（rename A→B、替换模式、接口迁移策略）
 - Constraints：是否允许行为变化？是否需要兼容期？是否允许自动格式化？
 - Verification：必须通过哪些命令/检查（最少一个）
 
 ## Procedure（default）
+
 1. **Baseline**
+
    - 确保工作区干净：`git status --porcelain`
    - 跑一个基线验证（至少 build 或核心测试子集），避免“本来就坏”
 
 2. **Enumerate**
+
    - 先搜索再改：用 `rg`/`git grep` 列出全部命中
    - 分类命中：真实调用 vs 注释/文档/样例；避免误改
 
 3. **Apply Mechanical Change**
+
    - 优先使用确定性的机械变换（脚本/结构化编辑）而非手工逐个改
    - 每轮改动后立即做小验证（编译/单测子集）
    - 复杂迁移优先“两阶段”：先兼容旧接口（deprecated），再清理旧接口
 
 4. **Format & Lint（按项目约定）**

 # Code Review Workflow
 
 ## When to Use This Skill
+
 - Review a PR / `git diff` / patch
 - Pre-merge quality gate (correctness/security/perf/tests)
 - Risky refactor, behavior change, auth/data path changes
 
 ## Inputs (required)
+
 - Change set: PR link or `git diff ...` output (must include context)
 - Goal: expected behavior / acceptance criteria (1–3 sentences)
 - Risk level: low|med|high (default: med)
 - Verification: test commands / repro steps (if unknown, ask first)
 
 ## Procedure
+
 1. **Triage**
+
    - Identify touched areas, public APIs, behavior changes, data/auth paths
    - Classify risk (blast radius, rollback difficulty)
 
 2. **Correctness**
+
    - Invariants, edge cases, error handling, null/empty, concurrency
    - Backward compatibility (inputs/outputs, wire formats, config)
 
 3. **Security**
+
    - AuthZ/AuthN boundaries, least privilege
    - Input validation, injection surfaces, secrets/log redaction
 
 4. **Maintainability**
+
    - Naming/structure/style aligned with Playbook docs
    - Complexity hotspots, duplication, clarity of intent
 
 5. **Performance**
+
    - Hot paths, algorithmic complexity, allocations/IO, N+1 patterns

 # Systematic Debugging（系统化调试）
 
 ## When to Use
+
 - Bugs, crashes, failing/flaky tests, regressions
 - “It doesn’t work” reports with unclear reproduction
 
 ## Inputs（required）
+
 - Expected vs actual behavior
 - Repro command/steps (or best-known approximation)
 - Logs/traces/screenshots/error output
 - Environment details (OS, versions, configs)
 
 ## Procedure（default）
+
 1. **Reproduce**
+
    - Make the failure deterministic if possible
    - Minimize repro steps (smallest input/command)
 
 2. **Localize**
+
    - Identify failing component and boundary conditions
    - Add temporary logging/assertions if needed (then remove)
 
 3. **Hypothesize & Test**
+
    - Form a small number of hypotheses
    - Design quick experiments to falsify each hypothesis

 - Avoid changing multiple variables at once
 - Prefer instrumentation and evidence over guessing
 - Keep fixes minimal and scoped

 # Verification Before Completion（先验证再宣称完成）
 
 ## When to Use
+
 - Any task where correctness matters (bug fixes, refactors, releases)
 - When the environment is complex or assumptions are likely
 
 ## Inputs（required）
+
 - What “done” means (acceptance criteria)
 - The smallest verification command(s) that prove it
 - Constraints: cannot run tests? no access? limited environment?
 
 ## Procedure（default）
+
 1. **Define Success Signals**
+
    - Tests passing, build artifacts produced, commands return 0
    - Specific output text or file diffs
 
 2. **Run the Smallest Check**
+
    - Start narrow (changed module tests) then broaden if needed
 
 3. **Record Evidence**
+
    - Capture key output lines, exit codes, and relevant file paths
 
 4. **Handle Gaps**
    - If verification can’t be run, say why and offer alternatives (manual checklist, static reasoning, targeted logs)
 
 ## Output Contract（stable）
+
 - What changed
 - What was verified (exact commands)
 - Evidence (exit codes / key outputs)

 - Prefer repeatable commands over subjective inspection

 # XLSX Workflow（Excel / 公式与校验）
 
 ## When to Use
+
 - 批量清洗数据、生成报表、对账
 - 需要编辑公式/格式/条件格式/数据验证
 - 需要“零错误”校验（避免 `#REF!/#DIV/0!/#NAME?` 等）
 
 ## Inputs（required）

 - Files: `.xlsx` 路径（以及是否有模板/受保护工作表）
 - Goal: 哪些 sheet/范围需要修改（明确列名/单元格范围）
 - Constraints: 是否允许改公式？是否必须保留原格式/保护/宏？

 ## Capability Decision（do first）
+
 1. 优先使用项目/环境已有的 **高保真工具链**（如果有）。
 2. 否则走开源 fallback（需确认可接受的行为差异）：
    - Python：`openpyxl`（结构化编辑；对公式重算能力有限/依赖 Excel 语义）
    - 数据处理：`pandas`（适合表格化数据，但要小心丢格式）
 
 ## Procedure（default）
+
 1. **Inspect**
    - Sheet 列表、命名、表头、冻结窗格、数据验证规则

 ## Guardrails
+
 - 表格数据可能含敏感信息：默认不在对话粘贴大表；用统计/摘要/行号定位
 - 批量变更必须给出可复现的变换规则（便于审计与回滚）
