 所有策略都遵循 `retries`、`timeout`、上下文注入、状态后端，并发出 `TaskEvent`。
 
+## 命令任务
+
+`TaskSpec` 的 `cmd` 参数支持执行外部命令，无需包装 Python 函数：
+
+```python
+graph = px.Graph.from_specs([
+    # 命令列表（推荐，参数无需转义）
+    px.TaskSpec("list_files", cmd=["ls", "-la"]),
+    # shell 字符串（支持管道、重定向）
+    px.TaskSpec("check_git", cmd="git status | head"),
+    # 带工作目录与超时
+    px.TaskSpec("build", cmd=["make", "all"], cwd=Path("/project"), timeout=300),
+    # 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),
+])
+```
+
+`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
+
+`CliRunner` 把多个 Graph 映射为命令行子命令，适合构建项目专属构建工具（替代 Makefile）：
+
+```python
+runner = px.CliRunner(
+    strategy="sequential",
+    description="My Build Tool",
+    graphs={
+        "clean": clean_graph,
+        "build": build_graph,
+        "test": test_graph,
+    },
+)
+runner.run_cli()  # 解析 sys.argv 并执行
+```
+
+命令行用法：
+
+```bash
+python build.py clean           # 执行 clean 图
+python build.py build --strategy thread   # 覆盖执行策略
+python build.py test --dry-run  # 仅打印执行计划
+python build.py --list          # 列出所有命令
+python build.py --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。
