+name: bulk-refactor-workflow
+description:
+  "Safe bulk refactors and mass edits across a repo (rename APIs, global
+  replacements, mechanical changes). Triggers: bulk refactor, mass edit, rename
+  symbol, global replace, 批量重构, 全局替换, 统一改名, 大范围修改."
+---
+
+# 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）**
+   - 仅在确认“会破坏 diff 可读性”前提下分批格式化（避免把重构和格式揉在一起）
+
+5. **Verify & Report**
+   - 跑约定的验证命令并记录输出
+   - 汇总影响范围：改动文件数、主要改动点、潜在风险
+
+## Execution Hint（optional）
+
+如果环境支持“执行型批量处理”（例如脚本执行），优先用脚本完成批量修改，然后只把**最小 diff + 摘要**交付，避免上下文膨胀与漏改。
+
+## Output Contract（stable）
+
+- Scope：改动覆盖范围（文件/目录/语言）
+- Transformation：执行的规则（可复用）
+- Changes：关键改动摘要（按类别）
+- Verification：命令 + 证据（输出/退出码/产物）
+- Risks：高风险点与回滚建议
+
+## Guardrails
+
+- 任何“全局替换”都必须先给出命中清单与排除策略
+- 避免把行为重构与格式化/无关清理混在同一轮

+description:
+  "Structured expert code review for TSL/C++/Python diffs or patches. Triggers:
+  code review, review PR, diff, 评审, 审查, 安全评审, 性能评审."
+---
+
+# 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
+
+6. **Tests & Verification**
+   - Map changes → tests; identify missing coverage
+   - Provide minimal verification plan (commands + expected signals)
+
+## Review Standards (Playbook as authority)
+
+- Commit message: `docs/common/commit_message.md`
+- TSL: `docs/tsl/code_style.md`, `docs/tsl/naming.md`, `docs/tsl/toolchain.md`
+- C++: `docs/cpp/code_style.md`, `docs/cpp/naming.md`, `docs/cpp/toolchain.md`
+- Python: `docs/python/style_guide.md`, `docs/python/tooling.md`,
+  `docs/python/configuration.md`
+
+## Output Contract (stable)
+
+- Summary: what changed & why
+- Risk: low|med|high + reasoning
+- Blockers: must-fix before merge (with file/line references when possible)
+- Non-blocking: Major / Minor / Nit
+- Questions: missing context / assumptions
+- Suggested verification: exact commands + what success looks like
+- Optional patch: minimal diff-style suggestions (only when unambiguous)

+  "基于 staged diff 生成符合 commit_message.md 的提交信息建议（:emoji:
+  type(scope): subject）。Triggers: commit message, 提交信息, 写提交说明,
+  生成提交信息, emoji commit, git commit."
+---
+
+# Commit Message（提交信息建议器）
+
+目标：基于 `git diff --cached`（staged
+diff）生成 1–3 条提交信息建议：`:emoji: type(scope): subject`（可选 body/footer）。
+
+权威规范（单一真源，优先就近路径）：
+
+- `docs/common/commit_message.md`
+- `docs/standards/playbook/docs/common/commit_message.md`（Playbook
+  vendoring 场景）
+
+## When to use
+
+- 用户要“写提交信息 / 生成 commit message / 按规范写提交说明 / emoji commit”
+- 已经 `git add` 了一批改动，准备 `git commit`
+
+## Procedure（default）
+
+1. **收集 staged 概览（尽量小上下文）**
+   - `git diff --cached --name-status`
+   - `git diff --cached --stat`
+   - 必要时只看关键文件：`git diff --cached -- <path>`
+
+2. **读取并遵循权威规范**
+   - 优先读取就近的
+     `commit_message.md`（见上方路径），以其中的 type/emoji/格式为准。
+
+3. **生成 1 条主建议 + 2 条备选**
+   - 格式固定：`:emoji: type(scope): subject`（scope 可省略）。
+   - subject 用一句话描述“做了什么”，避免含糊词；尽量 ≤ 72 字符，不加句号。
+
+4. **判断是否建议拆分提交**
+   - 当 staged 同时包含多个不相关模块/目的时：建议拆分，并给出拆分方式（按目录/功能点/风险）。
+
+5. **可选：补充 body/footer（如需要）**
+   - body：说明 why/impact/verify（按规范建议换行）。
+   - footer：任务号或 `BREAKING CHANGE:`（若有）。
+
+6. **只给建议，不默认执行 `git commit`**
+   - 仅当用户明确要求时，才根据选定方案生成最终提交信息。
+
+## Output contract（固定输出）
+
+- Detected: staged files summary（文件数 + 关键路径 + 是否可能需要拆分）
+- Proposed:
+  - Option A（recommended）：`:emoji: type(scope): subject`
+  - Option B：...

+name: create-plan
+description:
+  Create a concise plan. Use when a user explicitly asks for a plan related to a
+  coding task.
+metadata:
+  short-description: Create a plan
+---
+
+# Create Plan
+
+## Goal
+
+Turn a user prompt into a **single, actionable plan** delivered in the final
+assistant message.
+
+## Minimal workflow
+
+Throughout the entire workflow, operate in read-only mode. Do not write or
+update files.
+
+1. **Scan context quickly**
+   - Read `README.md` and any obvious docs (`docs/`, `CONTRIBUTING.md`,
+     `ARCHITECTURE.md`).
+   - Skim relevant files (the ones most likely touched).
+   - Identify constraints (language, frameworks, CI/test commands, deployment
+     shape).
+
+2. **Ask follow-ups only if blocking**
+   - Ask **at most 1–2 questions**.
+   - Only ask if you cannot responsibly plan without the answer; prefer
+     multiple-choice.
+   - If unsure but not blocked, make a reasonable assumption and proceed.
+
+3. **Create a plan using the template below**
+   - Start with **1 short paragraph** describing the intent and approach.
+   - Clearly call out what is **in scope** and what is **not in scope** in
+     short.
+   - Then provide a **small checklist** of action items (default 6–10 items).
+     - Each checklist item should be a concrete action and, when helpful,
+       mention files/commands.
+     - **Make items atomic and ordered**: discovery → changes → tests → rollout.
+     - **Verb-first**: “Add…”, “Refactor…”, “Verify…”, “Ship…”.
+   - Include at least one item for **tests/validation** and one for **edge
+     cases/risk** when applicable.
+   - If there are unknowns, include a tiny **Open questions** section (max 3).
+
+4. **Do not preface the plan with meta explanations; output only the plan as per
+   template**
+
+## Plan template (follow exactly)
+
+```markdown
+# Plan
+
+<1–3 sentences: what we’re doing, why, and the high-level approach.>
+
+## Scope
+
+- In:
+- Out:
+
+## Action items

+
+## Open questions
+
+- <Question 1>
+- <Question 2>
+- <Question 3>
+```
+
+## Checklist item guidance
+
+Good checklist items:
+
+- Point to likely files/modules: src/..., app/..., services/...
+- Name concrete validation: “Run npm test”, “Add unit tests for X”
+- Include safe rollout when relevant: feature flag, migration plan, rollback
+  note
+
+Avoid:
+
+- Vague steps (“handle backend”, “do auth”)
+- Too many micro-steps
+- Writing code snippets (keep the plan implementation-agnostic)

+  guardrails, harden, 分层校验, 多道防线, 安全加固."
+---
+
+# Defense in Depth（分层校验 / 多道防线）
+
+## When to Use
+
+- Auth/data path changes (permissions, roles, ownership checks)
+- Risky inputs (user input, external APIs, files, SQL, commands)
+- Operations that must be safe under retries/concurrency
+- Incidents where we fixed symptoms but not the root class of bugs
+
+## Inputs（required）
+
+- Data path: entrypoints → core logic → side effects (DB/files/network)
+- Threat model: what could go wrong? who can trigger it?
+- Constraints: latency budgets, backward compatibility, rollout plan
+- Verification: how to prove guardrails work (tests, logs, metrics)
+
+## Procedure（default）
+
+1. **Map the Path**
+   - Identify trust boundaries and validation points
+   - List invariants that must always hold
+
+2. **Layer Guardrails**
+   - AuthN/AuthZ checks at boundaries (least privilege)
+   - Input validation + normalization (reject early)
+   - Business invariants (defensive checks with clear errors)
+   - Idempotency / dedup / retry-safety
+   - Rate limits / resource bounds (timeouts, size limits)
+   - Observability (structured logs, metrics, alerts)
+
+3. **Failure Modes**
+   - Define what happens on invalid input, partial failures, timeouts
+   - Ensure errors are actionable and do not leak sensitive info
+
+4. **Verify**
+   - Add tests for each guardrail and key edge cases
+   - Propose minimal manual verification steps if tests are missing
+
+## Output Contract（stable）
+
+- Path map: trust boundaries + invariants
+- Guardrails: what to add at each layer (with rationale)
+- Risks: what remains and why
+- Verification: exact tests/commands and expected signals
+
+## Guardrails
+
+- Avoid “one big check”; prefer multiple small, well-scoped checks
+- Prefer explicit errors over silent fallback
+- Security checks must not be bypassable via alternate code paths

+  redline, tracked changes."
+---
+
+# Document Workflow（PDF/DOCX/PPTX/XLSX）
+
+## When to Use
+
+- Extract content: text/tables/metadata/forms from PDF; structured extraction
+  from Office docs
+- Apply edits: tracked changes/comments（docx）, slide updates（pptx）,
+  formulas/formatting（xlsx）
+- Generate deliverables: reports, slides, spreadsheets, exports (PDF)
+- Validate outputs: layout integrity, missing fonts, formula errors, file

+
+## Inputs（required）
+
+- Files: local paths（or confirm where they are in the repo）
+- Goal: what must change / what must be produced（include acceptance criteria）
+- Fidelity constraints: preserve formatting? track changes? template locked?
+- Output: desired format(s) + output directory/name
+- Environment: what tools are available (repo scripts, installed CLIs, Python
+  deps, MCP tools)
+
+## Capability Decision（do first）
+
+1. Prefer **repo-provided tooling** if it exists (scripts, make targets, CI
+   commands).
+2. If available, prefer **high-fidelity tooling** (Office-native conversions,
+   trusted CLIs, dedicated document libraries).
+3. Otherwise, confirm and use an **open-source fallback**:
+   - Python: `pypdf`, `pdfplumber`, `python-docx`, `python-pptx`, `openpyxl`,
+     `pandas`
+   - CLI (if installed): `libreoffice --headless`, `pdftotext`, `pdfinfo`
+
+## Procedure（default）
+
+1. **Triage**
+   - Identify file types, size/page counts, and what “correct” looks like
+   - Clarify constraints (legal docs? exact formatting? formulas? track
+     changes?)
+
+2. **Operate**
+   - Keep edits scoped and reproducible (scripted steps preferred for batch ops)
+   - Separate “content edits” from “format-only” changes when possible
+
+3. **Validate**
+   - Re-open / re-parse outputs; check errors, missing assets, broken formulas
+   - For xlsx: verify no `#REF!/#DIV/0!/#NAME?` etc (and recalc if tooling
+     supports it)
+   - For pdf: page count, text extract sanity, form fields if applicable
+
+4. **Report**
+   - Summarize edits, outputs, and any fidelity gaps/risks
+
+## Output Contract（stable）

+- Changes: per file, what changed & why
+- Validation: what checks ran + results
+- Constraints/limits: anything that could not be preserved
+- Next actions: optional improvements or questions for user

+   - Look for the first point where invariants were violated
+
+3. **Find the Trigger**
+   - What input/state/sequence causes it?
+   - What changed around that area (code/config/deps/data)?
+
+4. **Fix at the Right Layer**
+   - Prefer root-cause fix + defense-in-depth guardrails
+   - Add regression test or a deterministic repro harness
+
+5. **Validate**
+   - Reproduce before fix; verify after fix
+   - Add monitoring/alerts if appropriate
+
+## Output Contract（stable）
+
+- Summary: what broke and impact
+- Root cause: the earliest causal violation + why it happened
+- Trigger: minimal repro steps / conditions
+- Fix: what changed and why it prevents recurrence
+- Verification: tests/commands + evidence
+- Follow-ups: guardrails/observability/rollout notes
+
+## Guardrails
+
+- Don’t stop at “where it crashed”; find “why the bad state existed”
+- Separate contributing factors vs root cause
+- Avoid speculative RCA; label assumptions and request missing evidence

+name: style-cleanup
+description:
+  "Clean up formatting and code style with the repo’s existing toolchain
+  (clang-format/black/isort/flake8/pre-commit/etc). Triggers: 整理代码风格,
+  格式化, format, fmt, lint fix, clang-format, black, isort."
+---
+
+# Style Cleanup Workflow（整理代码风格 / 格式化）
+
+## When to Use
+
+- “整理代码风格 / 格式化 / format / fmt / lint fix”
+- 合并前做一次风格对齐（不做语义级重构）
+- 批量改动后，希望把格式化与机械性风格问题收敛到可控 diff
+
+## Inputs（required）
+
+- Scope：仅本次改动文件（默认）｜全仓库｜指定目录/文件类型
+- Languages：自动识别；如为多语言仓库请确认优先级
+- Verification：至少一个可执行的验证命令（如未知，先问/再推断）
+
+## Procedure（default）
+
+1. **Baseline**
+   - 记录当前状态：`git status --porcelain`
+   - 明确范围（默认只处理变更文件）：
+     - staged：`git diff --name-only --cached`
+     - unstaged：`git diff --name-only`
+     - untracked：`git ls-files -o --exclude-standard`
+
+2. **Detect Toolchain（prefer repo truth）**
+   - 优先用仓库既有入口脚本 / 配置：
+     - JS/TS：`package.json`
+       scripts（`format`/`lint`/`lint:fix`）、prettier/biome/eslint 配置
+     - Python：`pyproject.toml` / `.flake8` / `.pylintrc` /
+       `.pre-commit-config.yaml`
+     - C/C++：`.clang-format`（唯一真相），可选 `.clang-tidy`
+     - Shell：`shfmt`/`shellcheck`（若仓库已使用）
+     - Markdown：prettier/markdownlint（仅在仓库已固定时使用）
+   - 禁止默认“引入新 formatter/linter 配置”；缺配置时只做最小手工调整，并先确认是否允许落地配置文件。
+
+3. **Apply（format first, then lint）**
+   - 先 formatter（会改文件），再 lint（检查），再 lint
+     --fix（如有），最后再跑一次 check 确认干净。
+   - 默认只处理目标文件集合；避免全仓库 reformat（除非用户明确要求）。
+   - 典型命令（按仓库实际替换）：
+     - C++：`clang-format -i <files...>`；CI 校验：`clang-format --dry-run --Werror <files...>`
+     - Python：`black <files...>` + `isort <files...>`；或
+       `pre-commit run --files <files...>`
+     - JS/TS：`npm run format -- <files...>` / `pnpm ...` /
+       `npx prettier -w <files...>`（以项目脚本为准）
+
+4. **Guardrails**
+   - 只做风格与格式：不改变行为、不改 public API、不做重构。
+   - 如格式化导致 diff 暴涨（文件数/行数过大）：先停下，给出原因与两种方案让用户选：
+     1. 仅格式化本次改动文件（推荐默认）
+     2. 全仓库统一格式（通常需要单独 PR/提交）
+
+5. **Verify**
+   - 跑最小验证命令（仓库已有命令优先）。
+   - 若无法运行（缺环境/缺权限/缺依赖）：说明原因，并给出替代验证（例如 formatter 二次运行无 diff、lint 输出为 0）。
+
+## Playbook as Authority（如果项目 vendoring 了本 Playbook）
+
+当目标仓库包含 `docs/standards/playbook/docs/`（或直接包含
+`docs/tsl|cpp|python/...`），风格决策参考：
+
+- TSL：`docs/tsl/code_style.md`、`docs/tsl/naming.md`、`docs/tsl/toolchain.md`
+- C++：`docs/cpp/code_style.md`、`docs/cpp/naming.md`、`docs/cpp/toolchain.md`
+- Python：`docs/python/style_guide.md`、`docs/python/tooling.md`、`docs/python/configuration.md`
+
+## Output Contract（stable）
+
+- Scope：实际处理范围（文件/目录/语言）
+- Toolchain：使用了哪些工具与配置依据
+- Commands：实际执行命令（按顺序）
+- Changes：修改文件列表 + 改动规模概览
+- Remaining：仍未修复的问题（分类：formatter / lint / style）+ 下一步建议
+
+## Success Criteria
+
+- formatter 二次运行无新增 diff
+- lint/检查命令通过（或仅剩已确认的例外）
+- 未引入语义变更（仅格式/风格）
+
+## Failure Handling
+
+- 工具缺失：优先提示安装方式或替代命令；无法解决则退回“最小手工风格修复 + 明确未覆盖项”
+- 规则冲突（如 black vs flake8）：以仓库配置为准；必要时调整例外配置但需先确认

+# 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
+
+4. **Fix & Verify**
+   - Fix the root cause (not just symptoms)
+   - Add/update tests; rerun the minimal relevant suite
+
+## Output Contract（stable）
+
+- Repro: exact steps/command
+- Diagnosis: root cause + evidence
+- Fix: what changed + why it works
+- Verification: commands + outputs/exit codes
+- Follow-ups: hardening or cleanup tasks
+
+## Guardrails
+
+- 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)
+- What was not verified (and why)
+- Next steps (if any)
+
+## Guardrails
+
+- Don’t claim “fixed” without a verification signal
+- 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？
+- Output: 产物路径（xlsx + 可选导出 csv/pdf）
+- Environment: 可用工具（repo scripts、Python 依赖、`libreoffice --headless`
+  等）
+
+## 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
+   - 是否含外部链接、宏、受保护区域
+2. **Operate**
+   - 数据改动优先：保持表头不变、范围可追踪、避免隐式类型转换
+   - 公式改动：先定义输入/输出列，写最小可验证样例
+   - 格式改动：与业务逻辑分离，避免“数据+格式”混改造成回滚困难
+3. **Validate**
+   - 可用时做重新计算，并检查错误值：`#REF!/#DIV/0!/#NAME?/#VALUE!`
+   - 抽样核对：关键行/关键合计值/边界值
+
+## Output Contract（stable）
+
+- Summary：输入 → 输出（xlsx/csv/pdf）
+- Changes：按 sheet 列出（数据/公式/格式/验证规则）
+- Validation：重算/错误检查/抽样核对结果
+- Notes：fallback 模式的限制（公式重算、宏、外部链接）
+
+## 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）
