+# 文档整理与 Sphinx 文档搭建计划
+
+## Context
+
+最近完成 CLI 重构：新增 `pf` 统一入口，13 个工具迁移到 YAML 配置并删除了对应 .py 入口脚本，`run()` 的 verbose 统一应用到 spec。但文档未同步：README 仍引用旧命令（`yamlrun`、`python build.py`），模块结构表缺漏；`runner.py` 的 `_apply_verbose_to_graph` 成为死代码；项目缺少可发布的 Sphinx 文档。本次任务整理这些遗留，并搭建 ReadTheDocs 文档站。
+
+## 任务范围
+
+### 1. 清理死代码
+- 删除 `src/pyflowx/runner.py` 的 `_apply_verbose_to_graph` 函数（line 38-68），功能已移入 `executors.py` 的 `run()`。
+- 删除 `tests/test_runner.py` 中对应测试（line 610-636，`TestApplyVerboseToGraph` 类）。
+- 清理 `runner.py` 顶部 `from dataclasses import replace` 若变为未使用。
+
+### 2. 修复版本不一致
+- `src/pyflowx/__init__.py:105` 硬编码 `__version__ = "0.4.5"`，`pyproject.toml:25` 为 `0.3.5`。
+- 统一为 `0.4.5`（`__init__.py` 为准，pyproject.toml 是源但 bumpversion 工具应同时更新两者）。
+
+### 3. 更新 README.md
+- L304-308：`python build.py clean/build/test` → `pf pymake clean/build/test`。
+- L335-351、L435：`yamlrun pipeline.yaml ...` → `pf yamlrun pipeline.yaml ...`（6 处）。
+- L311：`verbose=True（默认）` 描述保留，但 CLI 示例改为 `pf`。
+- L558-574 模块结构表：补充 `cli/pf.py`（统一入口）、`cli/configs/`（YAML 工具配置）、`cli/_ops/`（工具函数）、`profiling.py`、`registry.py`。
+- 顶部增加「文档」徽章链接到 ReadTheDocs。
+
+### 4. 搭建 Sphinx 文档结构
+新建 `docs/` 目录：
+
+```

+```
+
+**conf.py 要点**：
+- 扩展：`sphinx.ext.autodoc`、`sphinx.ext.napoleon`（支持 Google/NumPy docstring）、`sphinx.ext.viewcode`、`myst_parser`（支持 Markdown）
+- 主题：`sphinx_rtd_theme`
+- 项目版本从 `pyflowx.__version__` 动态读取
+- `autodoc_default_options`：`members: True, undoc-members: True, show-inheritance: True`
+
+**api.rst**：用 `automodule:: pyflowx` 抓取 `__all__` 的 56 个公共符号。
+
+### 5. ReadTheDocs 配置
+- 新建 `.readthedocs.yaml`：Python 3.11，`pip install -e .[docs]`，`sphinx -b html docs/ docs/_build/`。
+- `.gitignore` 增加 `docs/_build/`。
+
+### 6. pyproject.toml 补充 docs 依赖
+```toml
+docs = [
+    "sphinx>=7.0",
+    "sphinx-rtd-theme>=2.0",
+    "myst-parser>=3.0",
+]
+```
+并在 `[dependency-groups]` 的 dev 中加入 `pyflowx[docs]`。
+
+## 关键文件
+
+| 文件 | 操作 |
+|------|------|
+| `src/pyflowx/runner.py` | 删除 `_apply_verbose_to_graph` |
+| `tests/test_runner.py` | 删除 `TestApplyVerboseToGraph` |
+| `src/pyflowx/__init__.py` | 版本统一（已 0.4.5，确认） |
+| `pyproject.toml` | 版本 → 0.4.5；加 docs 依赖 |
+| `README.md` | 更新 CLI 示例与模块结构表 |
+| `docs/conf.py` | 新建 |
+| `docs/*.rst` | 新建 |
+| `.readthedocs.yaml` | 新建 |
+| `.gitignore` | 加 docs/_build/ |
+
+## 验证
+
+1. **测试与 lint**：
+   ```bash
+   uv run pytest tests/ -q
+   uv run ruff check src/ tests/ docs/conf.py
+   uv run pyrefly check src/pyflowx/runner.py
+   ```
+
+2. **Sphinx 构建本地验证**：
+   ```bash
+   uv sync --extra docs
+   uv run sphinx-build -b html docs/ docs/_build/
+   ```
+   确认无 warning，打开 `docs/_build/index.html` 检查页面。
+
+3. **pf 功能回归**：
+   ```bash
+   pf gitt c
+   pf pymake b --dry-run
+   ```
+
+4. **RTD 配置校验**：`.readthedocs.yaml` 语法正确，`docs/conf.py` 能独立构建。
+
+## 不在范围
+
+- 不统一各模块 docstring 风格（napoleon 兼容 Google/NumPy，够用）。
+- 不重构现有 CLI 工具 YAML。
+- 不新增中文文档翻译（文档用中文撰写，与项目既有风格一致）。

+# Python 开发规范
+
+本规范结合 Python 最佳实践，作为编写与审查 Python 代码的统一标准。
+详细操作指南见 `.agents/skills/` 下相应技能。
+
+## 工具链（以 pyproject.toml 为准）
+
+| 工具 | 用途 | 配置要点 |
+|------|------|---------|
+| **ruff** | lint + format | `line-length=120`，`target-version="py38"` |
+| **pyrefly** | 类型检查 | `preset="strict"`，`python-version="3.8"` |
+| **pytest** | 测试 | `asyncio_default_fixture_loop_scope="function"`，marker `slow` |
+| **coverage** | 覆盖率 | `branch=true`，`fail_under=95`，`concurrency=["thread"]` |
+| **pre-commit** | 提交前检查 | ruff `--fix` + trailing-whitespace + end-of-file-fixer |
+
+验证（每次修改后必做）：
+
+```bash
+uvx --from pyflowx pymake tc
+uvx --from pyflowx pymake cov
+```
+
+## 兼容性
+
+- **最低 Python 3.8**：用 `from __future__ import annotations` 延迟注解求值；
+  按版本用 `typing.List`(3.8) → 内置泛型(3.9) → `X | Y`(3.10) → `typing.override`(3.12)。
+- **版本守卫**：`if sys.version_info >= (3, X):` 引入高版本 API；低版本回退分支加 `# pragma: no cover`。
+- **零运行时依赖**：仅依赖标准库（3.8 需 `graphlib_backport`、`typing-extensions`）。
+  新增依赖须审慎，优先用标准库。
+
+## 类型注解
+
+- **公共 API 必须有完整类型注解**，包括返回类型；私有函数也应有注解。
+- 泛型用 `TypeVar`；PEP 696 `default=` 仅 3.13+ 标准库支持，3.8–3.12 用 `typing_extensions.TypeVar`。
+- `Mapping`/`Sequence` 用于只读参数，`dict`/`list` 用于可变返回。
+- `Any` 仅用于真正动态场景（如 `Context` 跨任务异构映射）；任务内部类型必须完全静态。
+- 禁用裸 `# type: ignore`；确需时加具体规则码（如 `# type: ignore[union-attr]`）。
+- **`TYPE_CHECKING` 守卫**：仅类型检查需要的导入放 `if TYPE_CHECKING:` 块内，避免循环依赖。
+- **类型收窄**：用 `assert isinstance(x, Y)` 辅助 pyrefly 推断；`cast()` 仅用于类型系统无法表达的场景。
+
+## 数据结构
+
+- **不可变优先**：配置/描述类用 `@dataclass(frozen=True)`；可变类属性标注 `RUF012` 豁免。
+- **缓存**：实例级用 `functools.cached_property`，按参数键控用 `functools.lru_cache`；
+  不可哈希参数需 try/except 回退。修改被缓存数据源后必须手动清空缓存。
+- **抽象基类**：接口用 `abc.ABC` + `@abstractmethod`（如 `StateBackend`）。
+- **枚举**：状态/标志值用 `enum.Enum`（如 `TaskStatus`），禁止裸字符串/魔术数字；枚举值用 `UPPER_SNAKE`。
+- **`__repr__`**：可变类实现 `__repr__`（含关键字段）；`frozen=True` dataclass 自动生成。
+
+## 模块与导入
+
+- **单一职责**：每模块只做一件事（`task.py` 数据结构、`executors.py` 执行、`command.py` 命令、`compose.py` 组合）。禁止跨职责边界。
+- **导入顺序**（ruff isort）：`__future__` → 标准库 → 第三方 → 本地，各组间空行。
+- **惰性导入**：仅为打破循环依赖时使用，函数体内导入并注释说明；顶层导入是默认。
+- **`__all__`**：定义 `__all__` 显式声明导出符号，位置仅次于 `__future__` 之后。
+- **禁用 star imports**：`from x import *` 污染命名空间、破坏类型检查（`__init__.py` 聚合经 `__all__` 控制为例外）。
+- **避免 `utils.py`/`helpers.py`**：按职责归入对应模块。
+
+## 函数设计
+
+- **模块级函数优于 Mixin**：共享逻辑用模块级函数，类只持有状态与薄方法。
+- **静态方法慎用**：纯函数直接放模块级。
+- **参数 ≤ 5 个**为宜；超出用 dataclass 封装参数对象。
+- **单一职责**：一个函数做一件事；过长函数考虑拆分。
+- **异常范围要窄**：只捕获预期异常（如 `(TypeError, ValueError, KeyError, AttributeError)`），
+  **禁止** `except Exception` 掩盖 bug；捕获后至少 `logger.warning` 记录。
+- **可变默认参数**：`def f(x=[])` 是经典坑；用 `None` 哨兵或 `field(default_factory=list)`。
+
+## 异常处理
+
+- **自定义异常家族**：继承公共基类（如 `PyFlowXError`），按错误场景分类。
+- **异常包装**：`raise NewError(...) from exc` 保留因果链。
+- **不要吞异常**：捕获后必须处理（记录/包装/重抛），禁止空 `except: pass`。
+- **钩子/回调异常**：第三方回调异常仅记录，不影响主流程。
+
+## 并发与线程安全
+
+- **进程全局状态**（`os.environ`/`os.chdir`）在并发场景下必须用全局锁（`threading.RLock`）序列化。
+- **条件评估不可有可变状态**：组合条件（NOT/AND/OR）不得修改共享 `_reason`，避免竞态。
+- **批量 I/O**：循环内多次写盘改为批量一次（`contextmanager` 包裹延迟落盘）。
+- **信号量限流**：`concurrency_key` + `Semaphore` 按组限流。
+
+## 测试
+
+详细操作指南见 `.agents/skills/pyflowx-testing` 技能。硬约束：
+
+- **覆盖率 ≥ 95%**（branch coverage），不得下降。
+- **公共 API 优先测试**：用公共接口（`has`/`get`），不访问私有方法；
+  故障注入等场景可临时访问私有属性，docstring 注明原因。
+- **命名**：`test_<被测对象>_<场景>`。
+- **断言**：原生 `assert x == 1`，禁用 `self.assertEqual`；`pytest.raises` 必填 `match=`。
+- **Mock 优先级**：`monkeypatch` > 内联 stub > `unittest.mock` > `pytest-mock`。
+  禁用 `@patch` 装饰器、`mock.patch.object` 上下文、`pytest-mock` 的 `mocker` fixture。
+- **fixture**：`tmp_path`/`monkeypatch`/`capsys` 优先；autouse 仅全局必需时用。
+- **slow 标记**：耗时测试加 `@pytest.mark.slow`，CI 可 `-m "not slow"` 跳过。
+- **测试代码也跑 ruff**：`tests/**` 忽略 `ARG001`/`ARG002`。
+
+## 代码风格
+
+- **行宽 120**（ruff formatter 处理）。
+- **docstring**：公共 API 必须有；中文叙述 + 中文注释是本项目既有风格。
+- **打印和日志**：使用中文打印和日志，避免使用英文。
+- **命名**：`snake_case` 函数/变量，`PascalCase` 类，`UPPER_SNAKE` 常量，`_leading_underscore` 私有。
+- **字符串引号**：ruff 默认双引号。
+- **末尾单 `\n`**、**无尾随空格**（pre-commit 强制）。
+- **不用 emoji**：除非用户明确要求。
+
+## Pythonic 风格
+
+- **`is` 比较 `None`/`True`/`False`**：单例用 `is`，值用 `==`（PEP 8 E711/E712）。
+- **EAFP 优于 LBYL**：先尝试再处理异常，而非先检查再执行（避免竞态窗口）。
+- **truthiness**：`if items:` 优于 `if len(items) > 0:`。
+- **字符串格式化**：首选 f-string；`%` 仅用于 `logging` 延迟格式化。
+- **推导式**优于 `map`+`filter`；> 2 层拆为显式循环。
+- **`enumerate`** 替代 `range(len())`；**`zip`** 并行迭代（3.10+ 用 `strict=True`）。
+- **解包** `a, b = pair` 优于索引访问；忽略值用 `_`。
+- **海象运算符 `:=`**（3.8+）：赋值+判断合一，但不滥用。
+
+## 日志
+
+- **`logging.getLogger(__name__)`**：每模块独立 logger，禁用 `print` 调试残留。
+- **结构化上下文**：`extra={...}` 传字段；`logger.warning("task %r failed: %s", name, exc)` 优于 f-string（延迟格式化）。
+- **日志级别**：`DEBUG` 诊断 / `INFO` 关键流程 / `WARNING` 可恢复异常 / `ERROR` 需人工介入。
+- **禁止日志密码/密钥**：脱敏后再记录。
+
+## 路径与资源
+
+- **优先 `pathlib.Path`**：`Path("a") / "b"` 而非 `os.path.join`（ruff `PTH` 强制）；
+  禁止字符串拼接路径。类型注解用 `Path`，边界 `str` 立即包装。
+- **`with` 语句**：文件、锁、连接、临时目录一律用 `with` 或 `contextlib.contextmanager`；
+  多资源用 `contextlib.ExitStack`。
+- **显式关闭**：长生命周期对象（连接池、线程池）实现 `close()`，但优先 `with`。
+- **批量操作**：循环内多次 acquire/release 改为批量一次。
+
+## 安全
+
+- **禁用 `eval`/`exec`**：处理不可信输入时绝不使用；用 `ast.literal_eval` 或专用解析器。
+- **`subprocess`**：禁用 `shell=True` 除非命令完全可信；优先 `list[str]` 形式。
+- **凭证不入仓**：密钥/token/密码放 `.env` 或环境变量，`.gitignore` 必须包含 `.env`。
+- **日志脱敏**：记录请求/响应时移除 `Authorization`、`password` 等字段。
+- **依赖审计**：`uv lock` 后审阅新增依赖，避免引入已知 CVE 的包。
+
+## 性能要点
+
+- **避免重复计算**：循环内查询应缓存或预构建映射（如 `{name: spec}`）。
+- **避免双重查找**：`has(k)` + `get(k)` 改为单次 `get(k)` + `KeyError` 回退。
+- **统一校验**：入口校验一次，下游路径不重复（如 `run()` 统一 `validate()`，`layers()` 不再重复）。
+- **事件 emit**：任务生命周期必须 emit `RUNNING` → `SUCCESS`/`FAILED`/`SKIPPED`，
+  不要留死分支（`# pragma: no cover` 是清理信号，应激活或删除）。
+
+## Git 与提交
+
+- **自动提交**：任务完成后自动 `git add`（按文件名）+ `git commit` + `git push`（仅当分支已跟踪远程时执行 push；新分支跳过 push 并在总结中说明）。
+- **不修改 git config**。
+- **不运行破坏性命令**（`push --force`/`reset --hard`/`clean -f`）除非用户明确要求。
+- **staging**：按文件名添加，不用 `git add -A`/`git add .`，避免误加敏感文件。
+- **commit message**：简洁，聚焦"为什么"而非"是什么"；遵循仓库既有风格。

+# 自驱动开发规则
+
+本规则定义一种"目标驱动、闭环执行"的工作模式：仅在任务开始时与用户确认一次目标与边界，后续由 Agent 自主完成"计划 → 编码 → 测试 → 文档 → 验证"的迭代循环，直到用户目标达成。
+
+## 核心原则
+
+- **目标导向**：始终以用户最终目标为准绳，所有阶段产出都应服务于该目标。
+- **闭环执行**：每个子任务必须走完"计划 → 实现 → 测试 → 文档 → 验证"五步；禁止跳步留半成品。
+- **自主决策**：初始确认之后，实现路径、API 形态、重构范围、文件命名、测试组织、错误修复策略等由 Agent 自行决断，不再逐项请示。**可逆操作（编辑文件、运行测试、修复 lint、调整实现）直接执行，不询问**；只有不可逆/高风险操作才暂停。
+- **透明沟通**：每个阶段开始前用一句话说明意图；关键节点（完成、阻塞、转向）给简短更新；不复述内部思考，**不在收尾时停下询问"是否继续"或"是否提交"**——直接输出总结并结束。
+- **安全边界**：仅在高风险、不可逆操作或真正阻塞时才暂停找用户。
+
+## 初始确认（一次性，仅在最开始）
+
+任务启动时，用 `AskUserQuestion` 一次性确认以下信息（已由项目规范覆盖的不必重复确认）：
+
+1. **目标与范围**：要解决什么问题？交付物是什么？显式列出不在范围内的内容。
+2. **验收标准**：怎样算"完成"？可观测的判定条件（功能、性能、覆盖率阈值）。
+3. **特殊约束**：除 `python-standards.md` 之外的约束（兼容性、依赖限制、API 兼容策略等）。
+4. **测试要求**：覆盖率门槛（项目默认 ≥95%，branch）；是否需要新增 `slow` 标记。
+
+**git commit/push 不在确认范围内**：任务完成后自动 commit + push（仅当分支已跟踪远程时执行 push；新分支跳过 push 并在总结中说明），遵循 `.trae/rules/git-commit-message.md` 风格。仅 force-push、reset --hard、clean -f、修改 git config 等真正破坏性操作才需暂停确认。
+
+确认后，将目标与验收标准固化进 `TaskCreate` 任务列表，后续不再就同一信息反复询问。
+
+## 迭代循环
+
+下列五个阶段构成一个完整闭环。未达验收标准时，回到「计划」开启下一轮；达标准时，进入「收尾」。
+
+### 1. 计划（Plan）
+
+- 用 Explore/Glob/Grep 研究相关代码与既有模式，避免凭空设计。
+- 用 `TaskCreate` 把目标拆为可独立验证的子任务；每完成一项立即 `TaskUpdate` 为 completed。
+- 优先复用现有抽象；不为本轮假想需求设计接口。
+- 不过早抽象：三处相似才考虑提取，否则就地写。
+
+### 2. 实现（Code）
+
+- 严格遵守 `.trae/rules/python-standards.md` 与既有代码风格。
+- 优先 Edit 现有文件；新增文件需有明确职责边界。
+- 不引入运行时依赖（项目零依赖原则）；确需引入须在计划阶段说明。
+- 公共 API 必须有完整类型注解与中文 docstring。
+- 不写未被要求的功能、不为未来场景预留扩展点。
+
+### 3. 测试（Test）
+
+- 新增/修改的公共 API 必须配套测试；优先通过公共接口测试，故障注入可访问私有属性并在 docstring 注明。
+- Mock 优先级：`monkeypatch` > 内联 stub > `unittest.mock` > `pytest-mock`；禁用 `@patch` 装饰器。
+- 必跑校验（每次修改后）：
+
+  ```bash
+  uvx --from pyflowx pymake tc
+  uvx --from pyflowx pymake cov
+  ```
+
+- 测试失败时定位根因再修复，不通过放宽断言或 `# pragma: no cover` 绕过。
+- 覆盖率不得低于上一次的值（项目门槛 95%，branch）。
+
+### 4. 文档（Docs）
+
+- 同步更新 docstring、README、模块结构说明。
+- 行为变更须同步更新 `.agents/skills/pyflowx-development/SKILL.md` 中的对应章节。
+- 跨会话有价值的设计决策、约束、陷阱，追加到 memory（`project_memory.md` 或对应 `topics.md`）。
+- 不主动新建 `*.md` 文档；除非用户明确要求。
+
+### 5. 验证（Verify）
+
+- 逐条对照初始确认的「验收标准」核验；未满足则回到「计划」继续下一轮。
+- 全套门禁通过：ruff、pyrefly、pytest、coverage。
+- 给出本轮变更清单（改了哪些文件、为什么）。
+
+## 暂停条件（仅在以下情况中断自驱动找用户）
+
+1. **歧义无法自决**：需求存在多种合理解读且无既有约定可循。
+2. **高风险/不可逆操作**：删除非临时文件、`git push --force`、`reset --hard`、删表、修改 CI 配置、修改 git config、卸载依赖等。**普通 `git commit`/`push` 不属于此类**（任务完成后自动执行）。
+3. **不可恢复的失败**：根因不在本仓库、需外部环境/权限配合、或经两轮尝试仍无法定位。
+4. **超出初始确认范围**：用户目标在执行中发现需要显著扩大范围或改变方向。
+5. **用户主动询问**：用户在对话中提出新问题或要求澄清。
+
+**注意**："目标已达成"**不是**暂停条件——验收标准全部满足后直接进入收尾并结束任务，不询问"是否扩展范围"或"是否提交"。
+
+非以上情况，一律继续自驱动，不要为"求确认"而暂停。
+
+## 决策判据：该问还是自决
+
+遇到不确定时，按以下顺序判断：
+
+1. **是否不可逆/高风险？** 是 → 暂停确认（如删除文件、`push --force`、修改 CI 配置、卸载依赖）。否 → 继续。
+2. **是否在初始确认范围内？** 是 → 按确认执行，不询问。否 → 视为"超出初始确认范围"，暂停。
+3. **是否有既有约定可循？** 是 → 按约定执行（参考 `python-standards.md`、`project_memory.md`）。否 → 视为"歧义无法自决"，暂停。
+4. **是否可逆？** 是 → 直接执行，即使结果可能不完美（可在后续迭代修正）。否 → 暂停。
+
+**可直接自决（不询问）的典型情况**：
+
+- 测试失败、覆盖率不达标、lint/类型检查报错 → 定位根因并修复。
+- 代码风格选择（命名、模块划分、参数顺序）→ 自决。
+- 文件编辑、运行测试、运行校验命令 → 直接执行。
+- 任务完成后输出收尾总结 → 直接输出，不询问下一步。
+- 显式指定 `name` 参数以保持测试兼容性 → 自决。
+- 重命名局部变量以避免遮蔽 → 自决。
+
+**必须暂停询问的典型情况**：
+
+- 删除非临时文件、重命名公共模块/包。
+- `git push --force`、`reset --hard`、`clean -f`、修改 git config（普通 commit/push 自动执行，无需询问）。
+- 引入新的运行时依赖（违反项目零依赖原则）。
+- 修改 CI 配置、pre-commit 钩子、pyproject.toml 的工具链配置。
+- 卸载或降级既有依赖。
+
+## 沟通风格
+
+- 阶段切换时一句话说明即可；不要把内部推理写给用户看。
+- 完成子任务后用一两句总结改了什么、下一步做什么。
+- 遇到阻塞时直接说明：卡在哪、试了什么、需要用户做什么。
+- **不在收尾时询问"是否需要提交"或"是否扩展范围"**——直接输出总结并结束。用户后续若有新需求，由用户主动提出。
+- 不使用 emoji，除非用户明确要求。
+
+## 工具使用
+
+- 独立操作尽量并行调用（多个 Read/Grep/Glob 一批发出）。
+- 用 `TaskCreate`/`TaskUpdate` 维护进度，不批量推迟标记。
+- 长命令用后台运行（`run_in_background`），完成会自动通知。
+- 文件操作一律用专用工具：Read/Edit/Write/Glob/Grep，不用 `cat`/`sed`/`grep`/`find`。
+
+## 收尾
+
+- 验收标准全部满足后，**直接输出最终总结并结束任务**：交付物、关键决策、遗留事项。
+- **自动提交**：收尾时自动 `git add`（按文件名）+ `git commit`（遵循 `.trae/rules/git-commit-message.md` 风格）+ `git push`（仅当分支已跟踪远程时执行；新分支跳过 push 并在总结中说明）；**不询问**"是否需要提交"或"是否扩展范围"。
+- 若验收标准未全部满足，回到「计划」继续下一轮，不停下询问。
+- 将本次会话的关键产出与决策更新到 memory，便于后续会话续接。

+
+# PyFlowX 测试规范
+
+本技能是 `.trae/rules/python-standards.md` 测试章节的详细展开。
+规则文件仅保留硬约束指针，本文件提供完整操作指南。
+
+## 总则
+
+- **覆盖率 ≥ 95%**（branch coverage），不得下降。
+- **公共 API 优先测试**：测试用公共接口（`has`/`get`），不访问私有方法
+  （如 `_expired`）。兼容旧测试的私有方法应删除并迁移测试。
+  例外：`_store`/`_flush` 等内部状态在无法用公共 API 触发时（如模拟过期、
+  故障注入），可临时访问私有属性，并在 docstring 注明原因。
+- **命名**：`test_<被测对象>_<场景>`，如 `test_storage_key_cache_key_exception_returns_name`。
+- **每个测试一个断言重点**；多个断言要语义相关。
+- **slow 标记**：耗时测试加 `@pytest.mark.slow`，CI 可 `-m "not slow"` 跳过。
+- **测试代码也跑 ruff**：`tests/**` 忽略 `ARG001`/`ARG002`（未用 fixture 参数）。
+- **断言风格**：用原生 `assert` + 比较运算符（`assert x == 1`），
+  不用 `self.assertEqual`；pytest 会生成更清晰的 diff。
+
+## Mock 工具选择（强制）
+
+**优先级**：`monkeypatch` > 内联 stub > `unittest.mock` > `pytest-mock`。
+
+| 场景 | 工具 | 示例 |
+|------|------|------|
+| 替换模块属性 / 环境变量 / 工作目录 | `monkeypatch` | `monkeypatch.setattr(subprocess, "run", fake_run)` |
+| `os.environ["KEY"]` 临时设置 | `monkeypatch.setenv` | `monkeypatch.setenv("LOCALAPPDATA", "C:\\...")` |
+| 切换 cwd | `monkeypatch.chdir` | `monkeypatch.chdir(tmp_path)` |
+| 一次性 stub 函数 | 内联 lambda / 闭包 | `ran = []; monkeypatch.setattr(subprocess, "run", lambda *c, **__: ran.append(c))` |
+| 复杂 spy（记录调用次数/参数/返回序列） | `unittest.mock.MagicMock` | 仅当 lambda 不足以表达时 |
+| `with patch(...)` 上下文 | **禁用**（用 monkeypatch） | monkeypatch 自动 teardown 更安全 |
+
+**禁止**：
+- 不用 `pytest-mock` 的 `mocker` fixture（项目虽在 dev 依赖声明，但实际
+  测试代码未使用；为保持风格统一，新代码继续用 `monkeypatch`）。
+- 不用 `unittest.mock.patch` 装饰器（`@patch("x.y")`），它隐藏依赖且
+  与 pytest fixture 模式不兼容；用 `monkeypatch.setattr` 替代。
+- 不用 `mock.patch.object` 作为上下文管理器，除非被测代码本身就是
+  contextmanager（此时用 `monkeypatch.setattr` 仍更简单）。
+
+## monkeypatch 使用规范
+
+- **类型注解**：fixture 参数标注 `monkeypatch: pytest.MonkeyPatch`。
+- **作用域**：monkeypatch 自动在测试结束时撤销，**禁止**手动
+  `monkeypatch.setattr(x, "y", original)` 恢复（多余且容易遗漏）。
+  例外：在单个测试内需要中途恢复时，用 `monkeypatch.undo()` 全量撤销。
+- **替换目标**：替换"被测代码看到的对象"，而非全局对象本身。
+  - 错误：`monkeypatch.setattr("os.path.exists", fake)` —— 替换全局，影响其他模块。
+  - 正确：`monkeypatch.setattr(pyflowx.command.shutil, "which", fake)` ——
+    替换被测模块引用的 `shutil.which`。
+- **属性 vs 字符串路径**：优先属性访问形式 `monkeypatch.setattr(obj, "attr", val)`
+  而非字符串路径 `monkeypatch.setattr("pkg.mod.obj.attr", val)`，
+  前者有 IDE 跳转与重构支持。
+- **记录调用**：用闭包 `ran: list[tuple] = []` + `lambda *a, **k: ran.append((a, k))`
+  替代 `MagicMock`，可读性更好且无需导入。
+
+## Stub 与 Spy 模式
+
+- **轻量 stub**：内联定义 `class MockResult: returncode = 0; stdout = ""`，
+  替代 `MagicMock(return_value=...)`，类型明确且不引入 mock 依赖。
+- **状态收集**：闭包 + list 比 `mock.call_args_list` 更易断言：
+  ```python
+  calls: list[list[str]] = []
+
+
+  def fake_run(cmd: list[str], **_: Any) -> MockResult:
+      calls.append(cmd)
+      return MockResult()
+
+
+  monkeypatch.setattr(subprocess, "run", fake_run)
+  assert calls == [["clear"]]
+  ```
+- **副作用序列**：需要按调用次数返回不同值时，用 `itertools.cycle` 或
+  手动计数器，而非 `side_effect=[...]`（mock 专有 API）。
+- **异常注入**：`def raise_oserror(*a, **k): raise OSError("...")`，
+  用 `pytest.raises(OSError)` 验证，而非 `side_effect=OSError`。
+
+## 异常断言
+
+- **`pytest.raises`**：必填 `match=` 正则（除非异常消息完全不可预测），
+  避免误捕获同类异常：
+  ```python
+  with pytest.raises(StorageError, match="cannot write"):
+      b.save("a", 1)
+  ```
+- **异常链**：验证 `__cause__` 时用 `exc_info.value.__cause__`，
+  确认 `raise X from Y` 因果链完整。
+- **禁止** `try/except + assert False`：用 `pytest.raises` 替代。
+
+## Fixture 规范
+
+- **`tmp_path`**：处理临时文件，自动清理，禁止 `tempfile.mkdtemp()` 手动管理。
+- **`monkeypatch`**：环境变量、cwd、模块属性 mock（见上）。
+- **`capsys`/`capfd`**：捕获 stdout/stderr，验证日志或命令输出。
+- **autouse fixture**：仅在全局必需时用（如 `conftest.py` 的
+  `packtool_tmp_workdir` 自动切到 tmp_path）；否则显式声明参数。
+- **fixture 命名**：`snake_case`，描述"提供什么"而非"测试什么"
+  （`sample_graph` 优于 `test_data`）。
+- **fixture 作用域**：默认 `function`；`module`/`session` 仅当构造昂贵且
+  只读时，并加注释说明无副作用。
+
+## asyncio 测试
+
+- **fixture `loop_scope="function"`**（pyproject 已配置默认值）。
+- **async 测试**：`async def test_x():`，pytest-asyncio 自动驱动。
+- **await 检查**：测试异步函数必须 `await` 结果，禁止仅验证返回 coroutine 对象。
+- **异步 mock**：用 `AsyncMock`（3.8+ 在 `unittest.mock`）或
+  `async def fake(): return value`，禁用 `MagicMock(return_value=coro)`。
+
+## 参数化
+
+- **`@pytest.mark.parametrize`**：用 `ids` 参数提供可读标识：
+  ```python
+  @pytest.mark.parametrize(
+      ("strategy", "expected_workers"),
+      [("sequential", 1), ("thread", 8), ("async", 1)],
+      ids=["seq", "thread-8", "async"],
+  )
+  ```
+- **参数命名**：参数元组用有意义名称，而非 `("a", "b")`。
+- **组合爆炸**：参数组合 > 20 时拆分测试，避免单个测试函数臃肿。
+
+## 测试组织
+
+- **文件命名**：`test_<被测模块>.py`（`test_storage.py` 对应 `storage.py`）。
+- **类分组**：仅在测试逻辑强相关时用 `class TestXxx:` 分组；默认用模块级函数。
+- **docstring**：每个测试函数一句话说明"测试什么场景"，复杂场景补充"为什么"。
+- **setup/teardown**：优先 fixture；`setup_method`/`teardown_method` 仅在
+  无法用 fixture 表达时（罕见）。

+`TaskSpec` 是不可变的任务描述符（`Generic[T]`，返回类型一路传到 `RunReport`），是唯一需要配置的东西：
 
 ```python
 px.TaskSpec(

-    fn=fetch_user,               # 同步或异步函数

-    args=(uid,),                 # 静态位置参数（追加在注入参数后）
-    kwargs={"timeout": 30},      # 静态关键字参数
-    retries=3,                   # 失败重试次数（0 = 仅一次）
-    timeout=30.0,                # 超时秒数（None = 不限制）

+    allow_upstream_skip=False,  # 上游 SKIPPED/FAILED 时是否仍执行
+    continue_on_error=False,  # 本任务失败是否不中断整体
 )
 ```
 
+支持两种任务形态：
+
+- **函数任务**（`fn`）：普通 Python 函数，参数名驱动自动注入
+- **命令任务**（`cmd`）：执行外部命令，支持 `list[str]`、`str`（shell）、`Callable` 三种形态
+
+`skip_if_missing=True` 时，`list[str]` 类型的 `cmd` 会通过 `shutil.which` 检查命令是否存在，不存在则跳过任务（标记为 `SKIPPED`）而非失败。适用于构建工具场景，避免因未安装某些工具而导致整个图执行失败。
+
 ### Graph —— DAG 构建
 
 ```python
-graph = px.Graph.from_specs([...])   # 整批校验（推荐）
+# 图级默认值：TaskSpec 字段为 None 时回退
+defaults = px.GraphDefaults(retry=px.RetryPolicy(max_attempts=2), timeout=60.0)

-graph.describe()              # 人类可读摘要
-graph.subgraph(("api",))      # 按标签切片
+graph.validate()  # 显式校验（环检测）
+graph.layers()  # 拓扑分层（run() 入口已统一校验，直接调用需自行先 validate）

 graph.subgraph_by_names(("a", "b"))  # 按名称切片
+graph.map("fetch", [1, 2, 3], lambda i: TaskSpec(f"fetch_{i}", ...))  # 批量 fan-out
+```
+
+### 图组合 —— compose
+
+`compose` / `GraphComposer` 把带字符串引用的多个图展开为纯 `Graph`：
+
+```python
+graphs = {
+    "build": px.Graph.from_specs([px.TaskSpec("b", cmd=["echo", "b"])]),
+    "all": px.Graph.from_specs(["build", px.TaskSpec("t", cmd=["echo", "t"])]),
+}
+resolved = px.compose(graphs)  # "all" 图中的 "build" 引用被展开
+```
+
+引用格式：`"command_name"`（整个图）或 `"command_name.task_name"`（特定任务）。
+`CliRunner` 内部自动调用 `compose`。
+
+### 任务模板 —— task_template
+
+`task_template` 工厂批量生成相似 TaskSpec：
+
+```python
+fetch = px.task_template(
+    fn=fetch_url,
+    retry=px.RetryPolicy(max_attempts=5),
+    timeout=30.0,
+    tags=("api",),

+graph = px.Graph.from_specs([

-仓库 `examples/` 目录包含完整示例：
+`TaskSpec` 的 `cmd` 参数支持执行外部命令，无需包装 Python 函数：
 
-- [`etl_pipeline.py`](examples/etl_pipeline.py) —— ETL 流水线（sequential）
-- [`parallel_run.py`](examples/parallel_run.py) —— 并行执行对比（thread vs sequential）
-- [`async_aggregation.py`](examples/async_aggregation.py) —— 异步聚合 + Context 注入

+    px.TaskSpec("list_files", cmd=["ls", "-la"]),
+    # shell 字符串（支持管道、重定向）

+    # 命令不存在时自动跳过（而非失败）
+    px.TaskSpec("optional_tool", cmd=["maturin", "build"], skip_if_missing=True),
+])
+```
 
-运行：
+`verbose=True` 时打印执行的命令、工作目录、返回码与输出；`verbose=False` 时静默执行（失败信息仍包含 stderr）。
+
+`skip_if_missing=True` 时，`list[str]` 类型的 `cmd` 会通过 `shutil.which` 检查命令是否存在，不存在则跳过任务（标记为 `SKIPPED`）而非失败。适用于构建工具场景，避免因未安装某些工具而导致整个图执行失败。对于 `str`（shell）和 `Callable` 类型的 `cmd`，此参数无效。
+
+## 条件执行
+
+`conditions` 参数让任务按条件跳过（标记为 `SKIPPED`）：
+
+```python
+from pyflowx.conditions import IS_WINDOWS, BuiltinConditions
+
+graph = px.Graph.from_specs([
+    # 仅在 Windows 上运行
+    px.TaskSpec("win_only", cmd=["dir"], conditions=(IS_WINDOWS,)),
+    # 仅在 git 已安装时运行
+    px.TaskSpec(
+        "git_check",
+        cmd=["git", "--version"],
+        conditions=(BuiltinConditions.HAS_INSTALLED("git"),),
+    ),
+    # 组合条件
+    px.TaskSpec(
+        "prod_deploy",
+        fn=deploy,
+        conditions=(
+            BuiltinConditions.ENV_VAR_EQUALS("ENV", "prod"),
+            BuiltinConditions.HAS_INSTALLED("docker"),
+        ),
+    ),
+])
+```
+
+内置条件：`IS_WINDOWS` / `IS_LINUX` / `IS_MACOS` / `IS_POSIX` / `PYTHON_VERSION` / `HAS_INSTALLED` / `ENV_VAR_EXISTS` / `ENV_VAR_EQUALS` / `NOT` / `AND` / `OR`。
+
+## CLI 运行器

+    strategy="sequential",

+)
+runner.run_cli()  # 解析 sys.argv 并执行
+```
+
+命令行用法：
 
 ```bash
-python examples/etl_pipeline.py
-python examples/parallel_run.py
-python examples/async_aggregation.py
+pf pymake clean           # 执行 clean 图
+pf pymake build --strategy thread   # 覆盖执行策略
+pf pymake test --dry-run  # 仅打印执行计划
+pf pymake --list          # 列出所有命令
+pf pymake --quiet         # 静默模式
 ```
 
+`verbose=True`（默认）时打印任务生命周期（开始/成功/失败/跳过）与命令输出；`--quiet` 关闭。
+
+## YAML 任务编排
+
+PyFlowX 支持 GitHub Actions 风格的声明式 YAML 任务编排，从 YAML 文件直接加载任务图。
+
+### 编程式 API
+
+```python
+import pyflowx as px
+
+# 从 YAML 文件加载任务图
+graph = px.Graph.from_yaml("pipeline.yaml")
+report = px.run(graph, strategy="thread")
+
+# 或用函数式 API
+graph = px.load_yaml("pipeline.yaml")
+graph = px.parse_yaml_string("""
+jobs:
+  hello:
+    cmd: ["echo", "hello"]
+""")
+```
+
+### CLI 入口
+
+通过 `pf` 统一入口调用（详见 [pf 工具](#cli-工具) 章节）：
+
+```bash
+# 执行 YAML 任务图
+pf yamlrun pipeline.yaml
+
+# 指定执行策略
+pf yamlrun pipeline.yaml --strategy thread
+
+# 仅打印任务分层，不执行
+pf yamlrun pipeline.yaml --dry-run
+
+# 列出所有任务名
+pf yamlrun pipeline.yaml --list
+
+# 静默模式
+pf yamlrun pipeline.yaml --quiet
+```
+
+### YAML Schema（GitHub Actions 风格）
+
+```yaml
+strategy: thread              # 图级默认策略
+defaults:                     # 图级默认值
+  retry: {max_attempts: 3}
+  verbose: true
+  env: {CI: "true"}
+
+jobs:
+  setup:
+    cmd: ["git", "clone", "..."]
+    runs-on: linux
+
+  build:
+    needs: [setup]            # 依赖列表
+    cmd: ["python", "-m", "build"]
+    timeout: 300
+    retry: {max_attempts: 2, delay: 1.0}
+
+  test:
+    needs: [build]
+    cmd: ["python${{ matrix.version }}", "-m", "pytest"]  # 矩阵占位符
+    strategy:
+      matrix:                  # 笛卡尔积展开为 6 个任务
+        version: ["3.8", "3.9", "3.10"]
+        os: ["linux", "macos"]
+    if: "env.CI"               # 条件: 环境变量存在
+
+  lint:
+    needs: [build]
+    cmd: ["ruff", "check"]
+    if: "env.CI == 'true'"     # 条件: 环境变量等于
+
+  deploy:
+    needs: [test, lint]        # 矩阵依赖自动展开
+    cmd: ["twine", "upload"]
+    if: "env.DEPLOY_TOKEN != ''"
+    allow-upstream-skip: true
+    concurrency-key: deploy_lock
+```
+
+### 字段映射
+
+| YAML 字段 | TaskSpec 字段 | 说明 |
+|-----------|---------------|------|
+| `jobs.<id>` | `name` | job ID 作为任务名 |
+| `cmd` / `run` | `cmd` | `cmd` 为列表形式，`run` 为 shell 字符串 |
+| `needs` | `depends_on` | 依赖列表（矩阵任务自动展开） |
+| `if` | `conditions` | `success()` / `always()` / `env.VAR` / `env.VAR == 'x'` |
+| `strategy.matrix` | 矩阵扇出 | 笛卡尔积展开为多个任务 |
+| `${{ matrix.key }}` | 占位符 | 在 cmd/run/cwd/env 中替换 |
+| `timeout` | `timeout` | 超时秒数 |
+| `retry` | `retry` | `{max_attempts, delay, backoff, jitter}` |
+| `cwd` | `cwd` | 工作目录 |
+| `env` | `env` | 环境变量 |
+| `verbose` | `verbose` | 详细输出 |
+| `continue-on-error` | `continue_on_error` | 失败不中止整图 |
+| `skip-if-missing` | `skip_if_missing` | 命令不存在时跳过 |
+| `allow-upstream-skip` | `allow_upstream_skip` | 上游跳过时仍执行 |
+| `priority` | `priority` | 同层优先级 |
+| `concurrency-key` | `concurrency_key` | 并发限制键 |
+| `tags` | `tags` | 自由标签 |
+| `runs-on` | `tags`（追加） | 运行环境标签 |
+
 ## 断点续跑
 
 ```python
 from pyflowx import JSONBackend
 
 # 第一次运行：成功结果写入 state.json
-backend = JSONBackend("state.json")
+backend = JSONBackend("state.json", ttl=3600)  # ttl 秒数，过期条目自动忽略
 report = px.run(graph, strategy="sequential", state=backend)
 
-# 第二次运行：已缓存任务自动跳过
+# 第二次运行：已缓存任务自动跳过（状态为 SKIPPED）
 report = px.run(graph, strategy="sequential", state=backend)
-# report.results 中缓存任务状态为 SKIPPED
+```
+
+`run()` 内部以 `backend.batch()` 包裹整个执行：所有 `save` 延迟到运行结束时统一落盘一次
+（`JSONBackend` 从 O(N²) 降为 O(N) 磁盘写入；`MemoryBackend` 为 no-op）。
+
+**缓存键**：默认存储键为任务名。配置 `cache_key` 函数后，键为 `"name:cache_key_value"`，
+使不同输入产生独立缓存条目：
+
+```python
+px.TaskSpec(
+    "fetch_user",
+    fn=fetch_user,
+    cache_key=lambda ctx: str(ctx.get("uid")),  # 不同 uid 独立缓存
+)
 ```

+## 高级特性
+
+### 并发限制
+
+按 `concurrency_key` 分组限流，避免压垮下游资源：
+
+```python
+graph = px.Graph.from_specs([
+    px.TaskSpec("q1", fn=query_db, concurrency_key="db"),
+    px.TaskSpec("q2", fn=query_db, concurrency_key="db"),
+    px.TaskSpec("q3", fn=query_db, concurrency_key="db"),
+])
+# 同一时刻最多 2 个 "db" 组任务运行
+px.run(graph, strategy="async", concurrency_limits={"db": 2})
+```
+
+### 任务钩子
+
+`TaskHooks` 在任务生命周期触发（异常仅记录，不影响任务状态）：
+
+```python
+hooks = px.TaskHooks(
+    pre_run=lambda spec: print(f"start {spec.name}"),
+    post_run=lambda spec, value: print(f"done {spec.name}"),
+    on_failure=lambda spec, exc: alert(spec.name, exc),
+)
+px.TaskSpec("task", fn=work, hooks=hooks)
+```
+
+### 优先级
+
+同层内按 `priority` 降序执行（稳定排序）：
+
+```python
+px.TaskSpec("low", fn=work, priority=0)
+px.TaskSpec("high", fn=work, priority=10)  # 同层内先执行
+```
+
 ## 开发
 
 ```bash
 # 安装开发依赖
 uv sync --extra dev
 
-# 运行测试（含覆盖率）
-uv run pytest --cov=pyflowx --cov-fail-under=100
+# 运行测试（含覆盖率，阈值 95%）

+
+全局选项
+--------
+
+所有 YAML 工具支持以下全局选项：

+   :widths: 25 75
+
+   * - 选项
+     - 说明

+3. **``**kwargs``** 参数 → 接收所有依赖结果（dict）
+4. **``TaskSpec.args`` / ``kwargs``** → 为非依赖参数提供静态值

+Graph —— DAG 构建
+=================
+
+``Graph`` 管理任务集合，提供建构建、校验、分层、可视化能力。
+
+构建方式
+--------
+
+.. code-block:: python
+
+   # 图级默认值：TaskSpec 字段为 None 时回退
+   defaults = px.GraphDefaults(retry=px.RetryPolicy(max_attempts=2), timeout=60.0)
+
+   graph = px.Graph.from_specs([...], defaults=defaults)  # 整批校验（推荐）
+
+   # 或增量构建
+   graph = px.Graph(defaults=defaults)
+   graph.add(px.TaskSpec("a", fn_a))
+   graph.add(px.TaskSpec("b", fn_b, ("a",)))
+
+常用方法
+--------
+
+.. code-block:: python
+
+   graph.validate()                    # 显式校验（环检测）
+   graph.layers()                      # 拓扑分层（Kahn 算法）
+   graph.to_mermaid()                  # Mermaid 可视化
+   graph.describe()                    # 人类可读摘要
+   graph.subgraph(("api",))            # 按标签切片
+   graph.subgraph_by_names(("a", "b")) # 按名称切片
+   graph.map("fetch", [1, 2, 3], lambda i: TaskSpec(f"fetch_{i}", ...))  # 批量 fan-out
+
+图组合
+------
+
+``compose`` / ``GraphComposer`` 把带字符串引用的多个图展开为纯 ``Graph``：
+
+.. code-block:: python
+
+   graphs = {
+       "build": px.Graph.from_specs([px.TaskSpec("b", cmd=["echo", "b"])]),
+       "all": px.Graph.from_specs(["build", px.TaskSpec("t", cmd=["echo", "t"])]),
+   }
+   resolved = px.compose(graphs)  # "all" 图中的 "build" 引用被展开
+
+引用格式：``"command_name"``（整个图）或 ``"command_name.task_name"``（特定任务）。
+``CliRunner`` 内部自动调用 ``compose``。
+
+完整方法说明详见 :doc:`/api`。

+TaskSpec —— 任务描述
+=====================
+
+``TaskSpec`` 是不可变的任务描述符（``Generic[T]``，返回类型一路传到 ``RunReport``），是唯一需要配置的东西。
+
+主要参数说明：
+
+.. code-block:: python
+
+   px.TaskSpec(
+       name="fetch_user",              # 唯一标识
+       fn=fetch_user,                  # 同步或异步函数
+       cmd=["curl", "..."],            # 或: 执行命令（覆盖 fn）
+       depends_on=("auth",),           # 硬依赖（参与拓扑分层）
+       soft_depends_on=("cache",),     # 软依赖（仅注入，不参与分层）
+       args=(uid,),                    # 静态位置参数（追加在注入参数后）
+       kwargs={"timeout": 30},         # 静态关键字参数
+       retry=px.RetryPolicy(max_attempts=3, delay=1.0, backoff=2.0),
+       timeout=30.0,                   # 超时秒数（None = 不限制）
+       tags=("api", "user"),           # 自由标签，用于子图过滤
+       conditions=(is_prod,),          # 条件函数列表（全部为 True 才执行）
+       priority=10,                    # 同层内优先级（高优先执行，默认 0）
+       concurrency_key="db",            # 并发分组键（配合 concurrency_limits 限流）
+       cache_key=lambda ctx: str(ctx.get("uid")),  # 缓存键函数
+       hooks=px.TaskHooks(pre_run=..., post_run=..., on_failure=...),
+       cwd=Path("/tmp"),               # 命令工作目录（仅 cmd 模式）
+       env={"DEBUG": "1"},             # 环境变量覆盖
+       verbose=True,                   # 打印命令输出（仅 cmd 模式）
+       skip_if_missing=True,           # 命令不存在时自动跳过（仅 list[str] cmd）
+       allow_upstream_skip=False,      # 上游 SKIPPED/FAILED 时是否仍执行
+       continue_on_error=False,        # 本任务失败是否不中断整体
+   )
+
+两种任务形态
+------------
+
+- **函数任务**（``fn``）：普通 Python 函数，参数名驱动自动注入
+- **命令任务**（``cmd``）：执行外部命令，支持 ``list[str]``、``str``（shell）、``Callable`` 三种形态
+
+``skip_if_missing=True`` 时，``list[str]`` 类型的 ``cmd`` 会通过 ``shutil.which`` 检查命令是否存在，不存在则跳过任务（标记为 ``SKIPPED``）而非失败。
+
+重试策略
+--------
+
+``RetryPolicy`` 配置重试次数、延迟、退避：
+
+.. code-block:: python
+
+   retry = px.RetryPolicy(
+       max_attempts=3,    # 最大尝试次数
+       delay=1.0,         # 初始延迟秒数
+       backoff=2.0,       # 退避倍数
+       jitter=0.1,        # 随机抖动（避免惊群）
+       retry_on=(ConnectionError,),  # 仅对这些异常重试
+   )
+
+任务钩子
+--------
+
+``TaskHooks`` 在任务生命周期触发（异常仅记录，不影响任务状态）：
+
+.. code-block:: python
+
+   hooks = px.TaskHooks(
+       pre_run=lambda spec: print(f"start {spec.name}"),
+       post_run=lambda spec, value: print(f"done {spec.name}"),
+       on_failure=lambda spec, exc: alert(spec.name, exc),
+   )
+   px.TaskSpec("task", fn=work, hooks=hooks)
+
+任务模板
+--------
+
+``task_template`` 工厂批量生成相似 TaskSpec：
+
+.. code-block:: python
+
+   fetch = px.task_template(
+       fn=fetch_url,
+       retry=px.RetryPolicy(max_attempts=5),
+       timeout=30.0,
+       tags=("api",),
+   )
+   graph = px.Graph.from_specs([

+PyFlowX 文档
+============
+
+PyFlowX 是一个轻量、类型安全的 DAG 任务调度器：**参数名就是依赖声明**。
+无需装饰器、无需样板包装器，写一个普通函数，框架按参数名自动注入上游结果。
+
+特性
+----
+
+- **零样板** —— 参数名即依赖，框架自动注入上游结果
+- **四种执行策略** —— sequential（串行）、thread（线程池）、async（事件循环）、dependency（依赖驱动，最大化并行）
+- **类型安全** —— ``TaskSpec[T]`` 把返回类型一路传到 ``RunReport``
+- **DAG 校验** —— 构建时即时校验重名、缺失依赖、环
+- **自动分层** —— Kahn 算法分组，同层任务可并行
+- **重试与超时** —— 每个任务独立配置 ``RetryPolicy`` 与 ``timeout``
+- **并发限制** —— ``concurrency_key`` + ``concurrency_limits`` 按组限流
+- **断点续跑** —— ``MemoryBackend`` / ``JSONBackend``，成功结果可缓存复用
+- **命令任务** —— ``cmd`` 参数直接执行外部命令
+- **条件执行** —— ``conditions`` 按平台、环境变量等条件跳过任务
+- **YAML 任务编排** —— GitHub Actions 风格声明式任务图
+- **pf 统一 CLI** —— ``pf <tool> [command]`` 调用所有工具
+- **最小依赖** —— 仅依赖标准库 + PyYAML

+快速上手
+========
+
+核心思想：**参数名即依赖**。写一个普通函数，参数名匹配上游任务名，框架自动注入结果。
+
+最小示例
+--------
+
+.. code-block:: python
+
+   import pyflowx as px
+
+   def extract() -> list[int]:
+       return [1, 2, 3]

+
+三种任务形态
+------------
+
+1. **函数任务**（``fn``）：普通 Python 函数，参数名驱动自动注入
+2. **命令任务**（``cmd``）：执行外部命令，支持 ``list[str]`` / ``str``（shell）/ ``Callable``
+3. **YAML 声明式**：从 YAML 文件加载任务图

 执行器向后端查询某任务是否已有存储结果；若有则跳过该任务，并将其
 存储值注入下游任务。
 
-本模块刻意保持最小化：仅持久化*成功*结果（失败任务会重跑），存储
-形态为扁平的 ``{task_name: result}`` 映射。内置两个后端：
+存储键由 :meth:`TaskSpec.storage_key` 计算，默认为任务名；若任务配置
+了 ``cache_key``，则键为 ``"name:cache_key_value"``，使不同输入产生
+独立缓存条目。
 
-* :class:`MemoryBackend` —— 快速、进程内、无 I/O。默认。
-* :class:`JSONBackend` —— 持久化到 JSON 文件，支持跨进程续跑。
-
-两者均零依赖（``json`` 为标准库）。用户可子类化
-:class:`StateBackend` 接入 SQLite、Redis 等。
+支持 TTL：``has`` 在条目过期时返回 ``False``。

+    env:

+        任务在执行期间临时设置。
+    verbose:
+        是否打印详细输出。``True`` 时打印执行的命令、返回码与输出
+        （仅 ``cmd``），以及任务生命周期。
+    skip_if_missing:
+        仅对 ``cmd`` 为 ``list[str]`` 有效。``True`` 时通过
+        :func:`shutil.which` 检查命令是否存在，不存在则跳过。
+    allow_upstream_skip:
+        若为 ``True``，硬依赖被 SKIPPED 时本任务仍执行（软依赖不影响）。
+        适用于清理类任务。
+    strategy:
+        单任务执行策略覆盖。``None`` 表示继承图级策略。
+        ``"sequential"`` 同步直接调用；``"thread"``/``"async"`` 将同步
+        任务卸载到线程池，异步任务跑在事件循环上。

+        不打破层屏障。默认 ``0``。
+    concurrency_key:
+        并发限制分组键。具有相同键的任务共享一个信号量，限制同时
+        运行的实例数。具体限额由 :func:`run` 的 ``concurrency_limits``
+        参数提供 ``{key: limit}`` 映射。``None`` 表示不限制。
+    continue_on_error:
+        若为 ``True``，任务最终失败时不中止整图，仅标记本任务 FAILED，
+        其硬依赖下游被 SKIPPED，其余任务继续。默认 ``False``。
+    cache_key:
+        缓存键计算函数。若提供，则用其基于依赖上下文计算的字符串键
+        存取状态后端，使不同输入产生独立缓存条目。``None`` 表示用任务名。
+    hooks:
+        :class:`TaskHooks` 生命周期钩子。
+    executor:
+        同步任务的执行器：``"thread"``（默认，线程池）/ ``"process"``
+        （进程池，绕过 GIL，适合 CPU 密集型；``fn`` 须可 pickle）/
+        ``"inline"``（直接在事件循环线程调用，最快但会阻塞循环）。
