+# 方案C:移除 YAML,统一 @px.tool 装饰器配置
+
+## Context
+
+现状:YAML 配置(22 个文件)+ `register_fn` 函数(79 个)分裂严重。fn 模式下 YAML 沦为冗余参数表——参数要三处重复声明(`variables`/`cli.options`/`jobs.args`),表达力不足(跨平台逻辑被迫下沉 `register_fn`),失类型检查/IDE 支持,函数签名与 YAML `args:` 顺序远端耦合。**矩阵 0 个实际使用、`if:` 0 个实际使用**,YAML 的声明式 DAG 优势在 fn 工具集场景完全没发挥。
+
+目标:完全移除 YAML 支持,统一用 `@px.tool` 装饰器——函数签名驱动 CLI 生成,函数体即逻辑,DAG 编排通过装饰器参数(`needs`/`strategy`)表达。用户无感知迁移(别名/子命令/参数名全保持)。验收:全部门禁通过(ruff/pyrefly/pytest)且覆盖率 ≥95%。
+
+## 设计要点
+
+### 新模块 `src/pyflowx/tools.py`
+
+职责:`@px.tool` 装饰器 + `ToolSpec`(frozen dataclass)+ 全局注册表 + CLI 生成 + 执行入口。**不扩展 `registry.py`**(职责不同,@px.tool 直接持有函数对象)。
+
+### `@px.tool` API
+
+```python
+@px.tool("pdftool", subcommand="m", help="合并 PDF",
+         needs=["setup"], strategy="thread",  # DAG 编排参数
+         cmd=["..."],  # 可选:有 cmd 执行命令,无 cmd 执行函数体
+         hidden=False, allow_upstream_skip=False)
+def pdf_merge(
+    inputs: list[Path],                  # positional(无默认值)→ nargs="+"
+    output: Path = Path("merged.pdf"),   # option(有默认值)→ --output
+    password: str = "",                  # --password
+    dry_run: bool = False,               # bool 默认 False → --dry-run store_true
+    level: int = 5,                      # --level type=int
+    mode: Literal["a","b"] = "a",        # --mode choices=["a","b"]
+) -> None:
+    """函数体即逻辑(无 cmd 时执行;有 cmd 时签名仅驱动 CLI)."""
+    ...
+```
+
+**装饰器关键字参数**:`subcommand`、`help`、`description`、`cmd`、`needs`、`strategy`、`cwd`、`allow_upstream_skip`、`hidden`、`env`/`retry`/`timeout`(透传 TaskSpec)。
+
+**CLI 生成规则**(inspect.signature + typing.get_type_hints):
+- 无默认值 → positional;有默认值 → `--kebab-case` 选项
+- 类型映射:`list[X]`→`nargs="+"`、`Path`→`type=Path`、`bool`默认 False→`store_true`、`Literal`→`choices`、`int`/`float`→对应 type
+- 全局选项 `--dry-run`/`--quiet`/`--strategy`/`--list` 注入每个 subparser
+
+**执行分支**:
+- 有 `cmd`:TaskSpec 用 `cmd=cmd`,函数体不执行(签名仅驱动 CLI);cwd/env 从装饰器 + CLI kwargs 合并
+- 无 `cmd`:TaskSpec 用 `fn=func`,kwargs 透传
+- 聚合任务(有 needs 无 cmd 无函数逻辑):fn=noop
+
+**needs 传递依赖**:从 `_TOOL_REGISTRY[tool_name]` BFS 收集(复用 `_collect_with_deps` 思路),每个依赖生成 TaskSpec,构建子图 → `px.run(graph, strategy)`。
+
+**动态 cmd 改 fn 模式**:`piptool i`/`gittool clean` 等原 `cmd+${VAR}` 改为函数体内 `subprocess.run([...])`,消除 `${VAR}` 列表展开,模型更纯。
+
+### pf.py 路由改造
+
+- `_TOOL_ALIASES`(57 个)保留全量,值改为 tool_name(去掉 .yaml 含义)
+- `_run_yaml` → `_run_tool`:`importlib.import_module(f"pyflowx.ops.{tool_name}")` 触发注册 → 从 `_TOOL_REGISTRY[tool_name]` 取 subcommand → `run_tool(tool, subcommand, argv)` → 退出码 0/1/130
+- `_LEGACY_TOOLS` 保留 emlmanager/profiler;**删除 yamlrun**
+- `_list_tools` 改为遍历 `_TOOL_REGISTRY` 取 description
+
+### ops 模块重组
+
+从 6 个功能模块(`files/dev/media/system/llm/bumpversion`)重组为 **22 个工具模块**:`ops/pdftool.py`、`ops/pymake.py`、`ops/envdev.py` 等,一文件一工具,文件内多个 `@px.tool` = 多 subcommand。
+
+- 跨工具复用函数(如 `add_date_prefix` 被 filedate 用)放 `ops/_common.py`
+- 未被 YAML 引用的约 20 个 `register_fn`(辅助函数如 `get_file_timestamp`/`has_files`)去掉装饰器,降级为模块级私有函数
+- `register_fn`/`get_fn`/`has_fn` 在阶段5 一并移除(YAML 配套,失去用途)
+
+## 迁移路径(6 阶段)
+
+### 阶段1:核心实现 + 单元测试
+- 新增 `src/pyflowx/tools.py`、`tests/test_tools.py`
+- 覆盖:注册/重复检测/CLI 生成(各类型)/单命令执行/cmd 分支/fn 分支/聚合/DAG/hidden/全局选项/退出码三态
+- 验证:`tools.py` 单元测试通过,覆盖率 ≥95%
+
+### 阶段2:迁移简单单命令工具
+- 工具:clr/which/taskkill/reseticoncache/screenshot/dockercmd/lscalc
+- 新增 `ops/<tool>.py`,每个用 `@px.tool` 重写;删除对应 `configs/*.yaml`
+- 改 `tests/cli/test_*.py` 的 import 路径(函数体不变,测试基本不动)
+- 验证:`pf clr`/`pf which python` 端到端 + 测试通过
+
+### 阶段3:迁移多 subcommand fn 工具
+- 工具:pdftool(14子命令)/piptool/packtool/filedate/filelevel/folderback/folderzip/sshcopyid/autofmt/bumpversion
+- pdftool:函数签名已有完整类型注解,迁移最直接
+- piptool:`i`/`up` 的 cmd 改 fn 模式(`subprocess.run`)
+- bumpversion:positional `PART` 默认 "patch" + `--no-tag` store_true
+- 验证:每工具 `pf <tool> --list` + 至少一个 subcommand 端到端
+
+### 阶段4:迁移复杂工具
+- pymake:12 cmd job + 6 聚合(ba/bump/cov/tc/p/pb)+ 4 内部 job(`hidden=True`:pyrefly_check/git_add_all/git_push/test_coverage)
+- envdev:9 job,4 处 `allow_upstream_skip`;`install_rust` 用 needs + allow_upstream_skip
+- gittool:`a`/`i`/`isub` 是 fn,`c`/`p`/`pl` 是 cmd,`clean` 是 hidden cmd
+- sglang/msdownload:跨平台 + 多参数
+- 验证:`pf pymake tc`/`pf pymake b`/`pf envdev` 端到端
+
+### 阶段5:清理 YAML
+- 删除:`yaml_loader.py`、`configs/*.yaml`(22 个)、`cli/yamlrun.py`、`tests/test_yaml_loader.py`
+- 删除:`ops/{files,dev,media,system,llm,bumpversion}.py`(被 `ops/<tool>.py` 替代后)
+- 删除:`registry.py` 的 `register_fn`/`get_fn`/`has_fn`/`FnRegistry`(YAML 配套)
+- `__init__.py`:移除 `YamlLoadError`/`build_cli_parser`/`load_yaml`/`parse_yaml_string`/`run_cli`/`run_yaml`/`Graph.from_yaml`/`register_fn`/`get_fn`/`has_fn`/`FnRegistry`;新增 `tool`/`ToolSpec`/`run_tool`
+- `graph.py`:删 `from_yaml` 类方法
+- `pyproject.toml`:删 `yamlrun` 脚本入口、`pyyaml` 运行时依赖、`types-PyYAML` dev 依赖
+- 验证:全局无 `import yaml`、无 `load_yaml`/`run_cli` 残留引用
+
+### 阶段6:补充测试,覆盖率达标
+- `tests/test_tools.py` 扩展:覆盖所有装饰器分支
+- `tests/cli/test_*.py`(16 个):改为通过 `PfApp([tool, subcommand, ...]).run()` 或 `run_tool(...)` 测试
+- 删除 `tests/test_yaml_loader.py`
+- 验证:`pf pymake cov` ≥95% branch
+
+## 关键文件
+
+**新增**:
+- `src/pyflowx/tools.py`(核心,@px.tool 装饰器)
+- `src/pyflowx/ops/<tool>.py`(22 个工具模块)
+- `src/pyflowx/ops/_common.py`(跨工具复用函数)
+- `tests/test_tools.py`
+
+**修改**:
+- `src/pyflowx/cli/pf.py`(_run_yaml → _run_tool,加载 ops/<tool>.py)
+- `src/pyflowx/__init__.py`(API 导出调整)
+- `pyproject.toml`(删 yamlrun/pyyaml)
+- `tests/cli/test_*.py`(import 路径 + 测试入口)
+
+**删除**:
+- `src/pyflowx/yaml_loader.py`
+- `src/pyflowx/configs/*.yaml`(22 个)
+- `src/pyflowx/cli/yamlrun.py`
+- `tests/test_yaml_loader.py`
+- `src/pyflowx/ops/{files,dev,media,system,llm,bumpversion}.py`(被替代后)
+- `src/pyflowx/registry.py`(YAML 配套)
+
+## 可复用的现有实现
+
+- `_collect_with_deps`(yaml_loader.py:287):needs 传递依赖收集,迁到 tools.py
+- `_add_global_options`(yaml_loader.py:1017):全局选项注入,思路复用
+- `CliExitCode`(runner.py:30):退出码三态,直接复用
+- `px.Graph.from_specs` + `px.run`:DAG 构建与执行,直接复用
+- `TaskSpec`(task.py):任务描述符,@px.tool 内部构建它
+
+## CLI 兼容性
+
+- 57 个 pf 别名不变
+- 子命令名不变(pdftool m/s/c/...、pymake b/ba/tc/...)
+- 参数名不变(`--output`/`--password`/...,靠 snake_case→kebab-case 转换)
+- `--dry-run`/`--quiet`/`--strategy`/`--list` 全局选项保留
+- 退出码 0/1/130 三态保留
+
+## 风险与权衡
+
+- **动态 cmd 改 fn**:失去 cmd 任务的 verbose 输出(命令打印/returncode),但模型更统一;verbose 可在 fn 内手动 print
+- **Graph.from_yaml 移除**:破坏性公共 API 变更,changelog 说明;yamlrun 用户迁移到 pf
+- **ops 重组工作量大**:22 个工具模块从 6 个功能模块拆出,跨工具函数需识别;分阶段(2-4)渐进,每阶段可独立验证
+- **register_fn 移除**:20 个未被引用的函数降级私有,被 @px.tool 间接调用的内联或放 `_common.py`
+
+## 验证
+
+每阶段结束运行:
+```bash
+uv run ruff check . && uv run ruff format --check .
+uv run pyrefly check .
+uv run pytest --cov=pyflowx --cov-branch --cov-report=term-missing
+```
+
+端到端验证(阶段4 后):
+```bash
+pf clr                          # 单命令
+pf which python                 # 单命令 + positional

+pf                              # 列出所有工具
+```

+# 方案C 续接执行计划
+
+## Summary
+
+承接已批准的 `.trae/documents/方案C-迁移执行计划.md`。前序会话已完成**阶段1**(tools.py 测试 + 公共 API 导出)与**阶段2 的大部分工作**(7 个新 ops 模块创建 + pf.py 双路由 + 4 个测试文件 import 更新),但因上下文中断尚未收尾。本计划从当前状态起,完成阶段2 收尾,并继续执行阶段3-6,最终完全移除 YAML 支持,覆盖率 ≥95%。
+
+## Current State Analysis
+
+### 阶段1(已完成)
+- `src/pyflowx/tools.py`:完整实现 @px.tool 装饰器、ToolSpec、_TOOL_REGISTRY、CLI 生成、依赖收集、run_tool、三态退出码
+- `tests/test_tools.py`:110 测试全通过,覆盖率 96.91%
+- `src/pyflowx/__init__.py`:已导出 `tool`/`ToolSpec`/`run_tool`/`list_tools`/`list_subcommands`(同时保留 YAML API 供过渡)
+- `pyproject.toml`:已加 `[tool.ruff.lint.per-file-ignores]` 中 `src/pyflowx/tools.py = ["PLR0911"]`
+
+### 阶段2(进行中,待收尾)
+**已完成**:
+- 7 个新 ops 模块创建完成,均使用 `@px.tool` 装饰器:
+  - `ops/clr.py`(`clear_screen_run`)
+  - `ops/which.py`(`which_run`)
+  - `ops/taskkill.py`(`taskkill_run`)
+  - `ops/reseticoncache.py`(`reset_icon_cache_run`)
+  - `ops/screenshot.py`(`take_screenshot_full`/`take_screenshot_area`,双 subcommand)
+  - `ops/dockercmd.py`(`docker_login_tencent`,subcommand="login")
+  - `ops/lscalc.py`(`run_ls_dyna`/`run_ls_dyna_mpi`/`check_ls_dyna_status`,三 subcommand)
+- `pf.py` 已改双路由:`_run_yaml` → `_run_tool_or_yaml`(@px.tool 优先,YAML 回退)
+- 4 个测试文件 import 路径已更新:`test_reseticoncache.py`、`test_screenshot.py`、`test_lscalc.py`、`test_system_run.py`
+- 旧功能模块(`ops/system.py`、`ops/media.py`、`ops/dev.py`)中的原函数仍保留(`@px.register_fn`),供未迁移的 YAML 工具使用
+
+**待完成**:
+1. **test_envdev.py 无需改动**:该文件测试 `ops/dev.py` 中的 `docker_login_tencent` 等 10 个函数,这些函数在阶段4 前仍在 `dev.py` 中(`@px.register_fn` 装饰),`dockercmd.py` 中的 `@px.tool` 版本是独立副本,两者共存无冲突
+2. **删除 7 个 YAML 配置文件**:`configs/{clr,which,taskkill,reseticoncache,screenshot,dockercmd,lscalc}.yaml`
+3. **验证**:运行 ruff/pyrefly/pytest,确认阶段2 通过
+
+### 阶段3-6(未开始)
+- 阶段3:迁移 10 个多 subcommand fn 工具(pdftool/piptool/packtool/filedate/filelevel/folderback/folderzip/sshcopyid/autofmt/bumpversion)
+- 阶段4:迁移 5 个复杂工具(pymake/envdev/gittool/sglang/msdownload)
+- 阶段5:清理 YAML 与配套代码(yaml_loader.py/registry.py/configs 目录/旧 ops 功能模块)
+- 阶段6:补充测试,覆盖率达标 95%
+
+## Proposed Changes
+
+### 阶段2 收尾:删除 YAML + 验证
+
+**删除文件**(7 个):
+- `src/pyflowx/configs/clr.yaml`
+- `src/pyflowx/configs/which.yaml`
+- `src/pyflowx/configs/taskkill.yaml`
+- `src/pyflowx/configs/reseticoncache.yaml`
+- `src/pyflowx/configs/screenshot.yaml`
+- `src/pyflowx/configs/dockercmd.yaml`
+- `src/pyflowx/configs/lscalc.yaml`
+
+**验证**:
+```bash
+uv run ruff check . && uv run ruff format --check .
+uv run pyrefly check .
+uv run pytest tests/cli/test_{reseticoncache,screenshot,lscalc,system_run}.py -v
+uv run pytest tests/test_tools.py -v
+```
+
+端到端冒烟(可选,若环境允许):
+```bash
+pf clr
+pf which python
+pf lscalc --list
+```
+
+### 阶段3:迁移多 subcommand fn 工具(10 个)
+
+**工具清单**:`pdftool`(14 子命令)/`piptool`/`packtool`/`filedate`/`filelevel`/`folderback`/`folderzip`/`sshcopyid`/`autofmt`/`bumpversion`
+
+**新建文件**(10 个,`ops/<tool>.py`,一文件一工具):
+- `ops/pdftool.py`:14 个 `@px.tool("pdftool", subcommand="...")`,函数体来自 `ops/media.py`(`pdf_merge`/`pdf_split`/`pdf_compress`/`pdf_encrypt`/`pdf_decrypt`/`pdf_extract_text`/`pdf_extract_images`/`pdf_add_watermark`/`pdf_rotate`/`pdf_crop`/`pdf_info`/`pdf_ocr`/`pdf_reorder`/`pdf_to_images`/`pdf_repair`)
+- `ops/piptool.py`:多 subcommand(`i`/`up`/`un`/`re`/`fr`/`dl`),`i`/`up` 原 cmd 模式改 fn 模式
+- `ops/packtool.py`:来自 `ops/system.py`(`pack_source`/`pack_wheel`/`pack_dependencies`/`clean_build_dir`)
+- `ops/filedate.py`/`ops/filelevel.py`/`ops/folderback.py`/`ops/folderzip.py`:来自 `ops/files.py`
+- `ops/sshcopyid.py`:来自 `ops/system.py`(`ssh_copy_id`)
+- `ops/autofmt.py`:4 subcommand(`fmt`/`lint`/`doc`/`sync`),`fmt`/`lint` 原 cmd 改 fn 模式
+- `ops/bumpversion.py`:positional `part: str = "patch"` + `no_tag: bool = False`,直接调用 `bump_project_version`
+
+**关键决策**:
+- 函数签名保持不变(测试兼容),仅装饰器 `@px.register_fn` → `@px.tool(name, subcommand=...)` 变化
+- 参数名 snake_case,CLI 自动转 kebab-case,**保持 CLI 兼容**
+- `piptool i`/`up`:原 `cmd: ["pip","install","${PKG}"]` 改为 `def i(packages: list[str]) -> None: subprocess.run(["pip","install",*packages], check=True)`
+- `autofmt fmt`/`lint`:原 `cmd: ["ruff","format","${TARGET}"]` 改为 `def fmt(target: str = ".") -> None: subprocess.run(["ruff","format",target], check=True)`
+- `bumpversion`:原 `cmd: ["pf","bumpversion","patch"]` 改为直接调用 `bump_project_version` 函数(避免递归调用 pf)
+
+**测试更新**(10 个):
+- `tests/cli/test_pdftool.py`、`test_piptool.py`、`test_packtool.py`、`test_filedate.py`、`test_filelevel.py`、`test_folderback.py`、`test_folderzip.py`、`test_sshcopyid.py`、`test_autofmt.py`、`test_bumpversion.py`
+- import 路径:`from pyflowx.ops import <tool>` 或 `from pyflowx.ops.<tool> import <func>`
+- 函数调用不变(函数体未变)
+
+**删除文件**(10 个):
+- `configs/{pdftool,piptool,packtool,filedate,filelevel,folderback,folderzip,sshcopyid,autofmt,bumpversion}.yaml`
+
+**验证**:每工具 `pf <tool> --list` + 对应 cli 测试通过
+
+### 阶段4:迁移复杂工具(5 个)
+
+**工具清单**:`pymake`/`envdev`/`gittool`/`sglang`/`msdownload`
+
+**新建文件**(5 个):
+- `ops/pymake.py`:
+  - 12 个 cmd subcommand(`b`/`bc`/`sync`/`c`/`t`/`tf`/`bumpversion`/`bumpmi`/`doc`/`lint`/`tox`):`@px.tool("pymake", subcommand="b", cmd=["uv","build"])` + 函数体 `pass` 或 docstring
+  - hidden 内部 job(`test_coverage`/`pyrefly_check`/`git_add_all`/`git_push`/`git_push_tags`/`twine_publish`/`publish_python`):`hidden=True`,`cmd=[...]`
+  - 6 个聚合(`ba`/`bump`/`cov`/`tc`/`p`/`pb`):`needs=[...]` + 函数体 `pass`
+  - `cwd: Path = Path(".")` 作为函数签名参数,CLI `--cwd` 覆盖
+- `ops/envdev.py`:9 个 fn subcommand,来自 `ops/dev.py`;`install_rust` 用 `needs=["setup_rust","download_rustup"]` + `allow_upstream_skip=True`
+- `ops/gittool.py`:`a`/`i`/`isub` 是 fn,`c`/`p`/`pl` 是 cmd,`clean` 是 `hidden=True` cmd
+- `ops/sglang.py`/`ops/msdownload.py`:跨平台 fn,来自 `ops/llm.py`,`Constants.IS_LINUX`/`IS_WINDOWS` 判断在函数体内
+
+**关键决策**:
+- pymake 的 `cwd` 参数:`TaskSpec` 的 `cwd` 由 `_build_task_spec` 从函数签名参数 `cwd: Path = Path(".")` 取,CLI `--cwd` 透传
+- pymake `bumpversion` 子命令:保持 cmd 模式 `cmd=["pf","bumpversion","patch"]`(调用外部 pf 命令)
+- envdev 跨平台逻辑保留在函数体内,仅装饰器迁移
+- gittool `c`(clean)是 hidden,被 `tc`/`p` 通过 needs 引用
+
+**测试更新**(5 个):
+- `tests/cli/test_envdev.py`:`docker_login_tencent` import 从 `pyflowx.ops.dev` 改 `pyflowx.ops.dockercmd`;其余 envdev 函数从 `pyflowx.ops.envdev` 导入
+- `tests/cli/test_gittool.py`、`test_pymake.py`(若存在)、`test_llm.py`:import 路径改 `from pyflowx.ops import <tool>`
+
+**删除文件**(5 个):
+- `configs/{pymake,envdev,gittool,sglang,msdownload}.yaml`
+
+**验证**:`pf pymake tc`、`pf envdev --python-mirror aliyun`、`pf gittool a -m "msg"` 端到端;cli 测试通过
+
+### 阶段5:清理 YAML 与配套代码
+
+**删除文件**:
+- `src/pyflowx/yaml_loader.py`
+- `src/pyflowx/cli/yamlrun.py`
+- `src/pyflowx/registry.py`
+- `src/pyflowx/configs/`(整个目录,22 个 .yaml 已在前阶段删完,删目录本身)
+- `src/pyflowx/ops/{files,dev,media,system,llm,bumpversion}.py`(6 个功能模块,被 22 个工具模块替代)
+- `tests/test_yaml_loader.py`
+- `tests/test_registry.py`
+
+**修改文件**:
+- `src/pyflowx/__init__.py`:
+  - 删导入:`YamlLoadError`/`build_cli_parser`/`load_yaml`/`parse_yaml_string`/`run_cli`/`run_yaml`/`FnRegistry`/`get_fn`/`has_fn`/`register_fn`
+  - 删 `__all__` 对应条目
+- `src/pyflowx/graph.py`:删 `from_yaml` 类方法(若存在)
+- `src/pyflowx/cli/pf.py`:
+  - `_run_tool_or_yaml` → `_run_tool`:仅走 `importlib.import_module` + `run_tool`,删除 YAML 回退分支
+  - `_LEGACY_TOOLS` 删 `yamlrun`(保留 `emlman`/`profiler`/`pxp`)
+  - `_list_tools` 改为遍历 `_TOOL_REGISTRY` 取 description(不再读 YAML)
+  - `_tool_description` 删除(不再读 YAML)
+  - 模块 docstring 更新(去掉"YAML 配置"描述)
+- `src/pyflowx/ops/__init__.py`:从导入 6 个功能模块改为导入 22 个工具模块
+- `pyproject.toml`:
+  - `[project.scripts]` 删 `yamlrun`
+  - `[project] dependencies` 删 `pyyaml>=6.0.1`
+  - `[project.optional-dependencies] dev` 删 `types-PyYAML>=6.0.12`
+
+**全局检查**:
+```bash
+# 无残留 YAML 引用
+grep -rE "import yaml|load_yaml|run_cli|register_fn|YamlLoadError|build_cli_parser|parse_yaml_string|from_yaml|yamlrun" src/ tests/ || echo "OK"
+```
+
+### 阶段6:补充测试 + 覆盖率达标
+
+**扩展 `tests/test_tools.py`**:
+- 补齐阶段2-4 迁移中发现的边界(如 `cwd` 从 CLI 透传、`env`/`retry`/`timeout` 透传 TaskSpec、`_has_function_logic` 对 async 函数/类方法、`_unwrap_optional` 对 `X | None` 等)
+- 若 `tools.py` 覆盖率未达 95%,补齐
+
+**新增 `tests/cli/test_pf_routing.py`**:
+- 测试 `PfApp` 路由:已知别名 → `_run_tool`、legacy → `_run_legacy`、未知 → 退出码 1
+- 测试 `_list_tools` 输出格式
+
+**更新 `tests/cli/test_*.py`**:
+- 阶段2-4 已更新 import 路径,本阶段补充通过 `run_tool(...)` 或 `PfApp([tool, subcommand]).run()` 的端到端测试
+
+**覆盖率验证**:
+```bash
+uv run pytest --cov=pyflowx --cov-branch --cov-report=term-missing
+```
+- 目标:`pyflowx.tools` ≥95%、整体 ≥95%(branch)
+- 若 `ops/<tool>.py` 因跨平台分支未覆盖,补 mock 测试(`Constants.IS_LINUX`/`IS_WINDOWS`)
+
+**最终门禁**:
+```bash
+uv run ruff check . && uv run ruff format --check .
+uv run pyrefly check .
+uv run pytest --cov=pyflowx --cov-branch --cov-report=term-missing
+```
+全部门禁通过,覆盖率 ≥95%。
+
+## Assumptions & Decisions
+
+1. **延续已批准计划**:本计划是 `.trae/documents/方案C-迁移执行计划.md` 的续接,不改变其架构决策,仅推进执行
+2. **test_envdev.py 阶段2 不改**:该文件测试 `ops/dev.py` 函数,dev.py 在阶段4 前仍存在,无需改动;阶段4 迁移 envdev 时再统一更新
+3. **函数体复制策略**:阶段3-4 从旧功能模块复制函数体到新工具模块,旧模块在阶段5 统一删除,避免提前破坏未迁移工具
+4. **CLI 兼容**:57 个 pf 别名不变、子命令名不变、参数名(snake_case → kebab-case)不变、全局选项保留、退出码三态保留
+5. **cmd 任务改 fn 模式**:`piptool i`/`autofmt fmt` 等原 `cmd+${VAR}` 改为函数体内 `subprocess.run`,verbose 由函数内 `print` 补偿
+6. **聚合任务判定**:`_has_function_logic` 用 ast 分析函数体(pass/.../docstring 视为无逻辑),迁移时聚合任务的函数体写 `pass`
+7. **每阶段独立验证**:每阶段结束运行 ruff + pyrefly + pytest,确保不累积错误
+8. **自动提交**:每阶段完成且门禁通过后自动 git commit + push(分支已跟踪远程),遵循中文提交信息风格
+
+## Verification Steps
+
+每阶段结束运行:
+```bash
+uv run ruff check . && uv run ruff format --check .
+uv run pyrefly check .
+uv run pytest tests/ --cov=pyflowx --cov-branch --cov-report=term-missing -x
+```
+

+# 方案C 迁移执行计划
+
+## Summary
+
+承接已批准的高层设计 `.trae/documents/方案C-移除YAML-统一px-tool装饰器.md`。当前 `src/pyflowx/tools.py` 已完整实现(@px.tool 装饰器 + ToolSpec + 注册表 + CLI 生成 + 依赖收集 + run_tool 入口),其余所有代码仍处于旧 YAML 模式。本计划从当前状态起,执行 6 个阶段,完全移除 YAML 支持,统一用 `@px.tool` 装饰器,覆盖率 ≥95%。
+
+## Current State Analysis
+
+**已完成**:
+- `src/pyflowx/tools.py`(607 行):ToolSpec/`@tool`/注册表/`_add_func_args_to_parser`/`_collect_with_deps`/`_build_task_spec`/`run_tool`,完整实现三态退出码(0/1/130)
+
+**未完成(本计划覆盖)**:
+1. `tests/test_tools.py` 不存在
+2. `__init__.py` 仍导出 YAML API(`load_yaml`/`run_cli`/`YamlLoadError`/`build_cli_parser`/`parse_yaml_string`/`run_yaml`)+ `register_fn`/`get_fn`/`has_fn`/`FnRegistry`,未导出 `tool`/`ToolSpec`/`run_tool`/`list_tools`/`list_subcommands`
+3. `pf.py` 仍走 `_run_yaml` → `px.run_cli(config_path, argv)`,57 个别名指向 .yaml 文件;`_LEGACY_TOOLS` 含 `yamlrun`
+4. `ops/` 仍是 6 个功能模块(`files/dev/media/system/llm/bumpversion`),共 79 个 `@px.register_fn`;无 22 个工具模块
+5. `configs/` 仍有 22 个 .yaml 文件
+6. `tests/cli/test_*.py`(16 个)+ `tests/test_yaml_loader.py`(49KB)+ `tests/test_registry.py` 仍依赖旧结构
+7. `pyproject.toml` 仍含 `yamlrun` 脚本入口、`pyyaml` 运行时依赖、`types-PyYAML` dev 依赖
+8. `src/pyflowx/yaml_loader.py`、`src/pyflowx/cli/yamlrun.py`、`src/pyflowx/registry.py` 仍存在
+9. `graph.py` 仍含 `from_yaml` 类方法(若存在)
+
+**关键依赖关系**:
+- `register_fn` 函数被 YAML `fn:` 字段引用,迁移后改用 `@px.tool` 直接持有函数对象,不再需要 `register_fn`/`get_fn`/`has_fn`
+- 现有 `tests/cli/test_*.py` 直接调用 `media.pdf_merge(...)`/`dev._get_installed_packages()` 等函数体,迁移后函数体不变,仅 import 路径与装饰器变化
+- `tools.py` 中 `run_tool` 依赖 `px.Graph.from_specs` + `px.run`,与 YAML 无耦合,可直接使用
+
+## Proposed Changes
+
+### 阶段1:tools.py 单元测试 + 公共 API 导出
+
+**文件**:
+- 新建 `tests/test_tools.py`
+- 修改 `src/pyflowx/__init__.py`
+
+**test_tools.py 覆盖点**(对应 `tools.py` 各分支):
+1. 注册:`@tool` 装饰器注册到 `_TOOL_REGISTRY`,`list_tools`/`list_subcommands`/`get_tool`/`clear_tool_registry`
+2. 重复检测:同名同 subcommand 二次注册抛 `ValueError`
+3. CLI 生成各类型:
+   - positional(无默认值)/ option(有默认值)
+   - `list[Path]` → `nargs="+"`
+   - `Literal["a","b"]` → `choices`
+   - `int`/`float`/`Path`/`str` → `type=`
+   - `bool` 默认 False → `--flag store_true`;默认 True → `--no-flag store_false`
+   - `Optional[X]` → `_unwrap_optional`
+4. 单命令工具执行:`run_tool` 返回 0(成功)/1(失败)/130(KeyboardInterrupt)
+5. cmd 分支:`cmd=["..."]` 时构建 TaskSpec 用 cmd,函数体不执行
+6. fn 分支:无 cmd 时执行函数体,kwargs 透传
+7. 聚合任务:`_is_aggregate` 判定 pass/.../docstring,fn=`_noop`
+8. DAG:`_collect_with_deps` BFS 拓扑顺序(依赖在前)
+9. hidden:`list_subcommands(include_hidden=False)` 排除,`_build_parser` 不暴露
+10. 全局选项:`--dry-run`/`--quiet`/`--strategy`/`--list`
+11. 退出码三态:成功 0、`TaskFailedError` → 1、`PyFlowXError` → 1、`KeyboardInterrupt` → 130
+12. 未注册工具:`run_tool("unknown")` → 1,stderr 提示
+13. `_handle_list` 输出格式
+14. `_snake_to_kebab` 转换
+
+**__init__.py 改动**:
+- 新增导入:`from .tools import ToolSpec, list_subcommands, list_tools, run_tool, tool`
+- 新增 `__all__` 条目:`ToolSpec`/`list_subcommands`/`list_tools`/`run_tool`/`tool`
+- 暂时**保留** YAML/register_fn 导出(阶段5 才删),避免提前破坏
+
+**验证**:`uv run pytest tests/test_tools.py --cov=pyflowx.tools --cov-branch` 通过,`tools.py` 覆盖率 ≥95%
+
+### 阶段2:迁移简单单命令工具(7 个)
+
+**工具**:`clr`/`which`/`taskkill`/`reseticoncache`/`screenshot`/`dockercmd`/`lscalc`
+
+**新建文件**(`ops/<tool>.py`,一文件一工具):
+- `ops/clr.py`:`@px.tool("clr")` 包装 `clear_screen_run`(来自 `ops/system.py`)
+- `ops/which.py`:`@px.tool("which")` 包装 `which_run`
+- `ops/taskkill.py`:`@px.tool("taskkill")` 包装 `taskkill_run`
+- `ops/reseticoncache.py`:`@px.tool("reseticoncache")` 包装 `reset_icon_cache_run`
+- `ops/screenshot.py`:`@px.tool("screenshot")` 包装 `take_screenshot_full`/`take_screenshot_area`(两个 subcommand)
+- `ops/dockercmd.py`:`@px.tool("dockercmd")` 包装 `docker_login_tencent`
+- `ops/lscalc.py`:`@px.tool("lscalc")` 包装 `run_ls_dyna`/`run_ls_dyna_mpi`/`check_ls_dyna_status`(多 subcommand)
+
+**函数迁移策略**:
+- 从 `ops/system.py` 把对应函数体复制到新 `ops/<tool>.py`,改 `@px.register_fn` 为 `@px.tool(...)`
+- 函数签名保持不变(测试兼容),仅装饰器变化
+- 跨工具复用的常量(`LS_DYNA_COMMANDS` 等)若被多工具引用,放 `ops/_common.py`;否则就地保留
+
+**测试更新**:
+- `tests/cli/test_reseticoncache.py`、`test_screenshot.py`、`test_lscalc.py`、`test_system_run.py`:import 路径从 `from pyflowx.ops import system` 改为 `from pyflowx.ops import <tool>`
+- 函数调用不变(`system.clear_screen_run()` → `clr.clear_screen_run()` 或类似)
+
+**删除**:`configs/{clr,which,taskkill,reseticoncache,screenshot,dockercmd,lscalc}.yaml`(7 个)
+
+**验证**:`pf clr`、`pf which python`、`pf lscalc --list` 端到端可用;`uv run pytest tests/cli/test_{reseticoncache,screenshot,lscalc,system_run}.py` 通过
+
+### 阶段3:迁移多 subcommand fn 工具(10 个)
+
+**工具**:`pdftool`(14 子命令)/`piptool`/`packtool`/`filedate`/`filelevel`/`folderback`/`folderzip`/`sshcopyid`/`autofmt`/`bumpversion`
+
+**新建文件**:
+- `ops/pdftool.py`:14 个 `@px.tool("pdftool", subcommand="m"/"s"/"c"/...)`,函数来自 `ops/media.py`
+- `ops/piptool.py`:多 subcommand(`i`/`up`/`un`/`re`/`fr`/`dl`),`i`/`up` 原 cmd 模式改 fn 模式(`subprocess.run` 在函数体内)
+- `ops/packtool.py`:多 subcommand,来自 `ops/system.py`(`pack_source`/`pack_wheel`/`pack_dependencies`/`clean_build_dir`)
+- `ops/filedate.py`/`filelevel.py`/`folderback.py`/`folderzip.py`:来自 `ops/files.py`
+- `ops/sshcopyid.py`:来自 `ops/system.py`(`ssh_copy_id`)
+- `ops/autofmt.py`:4 subcommand(`fmt`/`lint`/`doc`/`sync`),`fmt`/`lint` 原 cmd 改 fn 模式
+- `ops/bumpversion.py`:positional `PART` 默认 "patch" + `--no-tag store_true`,来自 `ops/bumpversion.py`
+
+**关键决策**:
+- pdftool 函数签名已有完整类型注解,迁移最直接;`pdf_merge(input_paths: list[Path], output_path: Path)` → `@px.tool("pdftool", subcommand="m")` + `inputs: list[Path]`(positional nargs="+") + `output: Path = Path("merged.pdf")`
+- 参数名映射:YAML 的 `INPUTS`/`OUTPUT`/`PASSWORD` → snake_case `inputs`/`output`/`password`,CLI 自动转 kebab-case `--output`/`--password`,**保持 CLI 兼容**
+- `piptool i`/`up`:原 `cmd: ["pip", "install", "${PKG}"]` 改为 `def i(packages: list[str]) -> None: subprocess.run(["pip", "install", *packages], check=True)`
+- `autofmt fmt`/`lint`:原 `cmd: ["ruff", "format", "${TARGET}"]` 改为 `def fmt(target: str = ".") -> None: subprocess.run(["ruff", "format", target], check=True)`
+- bumpversion:positional `part: str = "patch"` + `no_tag: bool = False`(store_true),原 `cmd: ["pf", "bumpversion", "patch"]` 改为直接调用 `bump_project_version` 函数
+
+**测试更新**:
+- `tests/cli/test_pdftool.py`、`test_piptool.py`、`test_packtool.py`、`test_filedate.py`、`test_filelevel.py`、`test_folderback.py`、`test_folderzip.py`、`test_sshcopyid.py`、`test_autofmt.py`、`test_bumpversion.py`:import 路径改 `from pyflowx.ops import <tool>`
+- 函数调用不变(函数体未变)
+
+**删除**:`configs/{pdftool,piptool,packtool,filedate,filelevel,folderback,folderzip,sshcopyid,autofmt,bumpversion}.yaml`(10 个)
+
+**验证**:每工具 `pf <tool> --list` + 至少一个 subcommand 端到端;对应 cli 测试通过
+
+### 阶段4:迁移复杂工具(5 个)
+
+**工具**:`pymake`/`envdev`/`gittool`/`sglang`/`msdownload`
+
+**新建文件**:
+- `ops/pymake.py`:
+  - 12 个 cmd subcommand(`b`/`bc`/`sync`/`c`/`t`/`tf`/`bumpversion`/`bumpmi`/`doc`/`lint`/`tox`):`@px.tool("pymake", subcommand="b", cmd=["uv","build"])` + `def b(cwd: Path = Path(".")) -> None: pass`
+  - 4 个 hidden 内部 job(`test_coverage`/`pyrefly_check`/`git_add_all`/`git_push`/`git_push_tags`/`twine_publish`/`publish_python`):`hidden=True`,`cmd=[...]`
+  - 6 个聚合(`ba`/`bump`/`cov`/`tc`/`p`/`pb`):`needs=[...]` + 函数体 `pass`
+  - `cwd: Path = Path(".")` 作为函数签名参数,CLI `--cwd` 覆盖
+- `ops/envdev.py`:9 个 fn subcommand,4 处 `allow_upstream_skip=True`;`install_rust` 用 `needs=["setup_rust","download_rustup"]` + `allow_upstream_skip=True`
+- `ops/gittool.py`:`a`/`i`/`isub` 是 fn,`c`/`p`/`pl` 是 cmd,`clean` 是 `hidden=True` cmd
+- `ops/sglang.py`/`ops/msdownload.py`:跨平台 fn(来自 `ops/llm.py`),`Constants.IS_LINUX`/`IS_WINDOWS` 判断在函数体内
+
+**关键决策**:
+- pymake 的 `cwd` 参数:`TaskSpec` 的 `cwd` 由 `_build_task_spec` 从 `variables["cwd"]` 取,CLI `--cwd` 透传;装饰器级 `cwd=None`
+- pymake `bumpversion` 子命令:原 `cmd: ["pf","bumpversion","patch"]` 改为直接 `cmd=["pf","bumpversion","patch"]`(保持 cmd 模式,因调用外部 pf 命令)
+- envdev 跨平台逻辑保留在函数体内(已实现),仅装饰器迁移
+- gittool `c`(clean)是 hidden,被 `tc`/`p` 通过 needs 引用
+
+**测试更新**:
+- `tests/cli/test_envdev.py`、`test_gittool.py`、`test_llm.py`:import 路径改 `from pyflowx.ops import <tool>`
+- `test_pdftool.py` 等(若引用 gittool/pymake 的函数)同步改
+
+**删除**:`configs/{pymake,envdev,gittool,sglang,msdownload}.yaml`(5 个)
+
+**验证**:`pf pymake tc`、`pf pymake b`、`pf envdev --python-mirror aliyun`、`pf gittool a -m "msg"` 端到端;cli 测试通过
+
+### 阶段5:清理 YAML 与配套代码
+
+**删除文件**:
+- `src/pyflowx/yaml_loader.py`
+- `src/pyflowx/cli/yamlrun.py`
+- `src/pyflowx/registry.py`
+- `src/pyflowx/configs/`(整个目录,22 个 .yaml 已在前阶段删完,删目录本身)
+- `src/pyflowx/ops/{files,dev,media,system,llm,bumpversion}.py`(6 个功能模块,被 22 个工具模块替代)
+- `tests/test_yaml_loader.py`
+- `tests/test_registry.py`(若专为 register_fn 写;若含其他内容则保留并更新)
+
+**修改文件**:
+- `src/pyflowx/__init__.py`:
+  - 删导入:`YamlLoadError`/`build_cli_parser`/`load_yaml`/`parse_yaml_string`/`run_cli`/`run_yaml`/`FnRegistry`/`get_fn`/`has_fn`/`register_fn`
+  - 删 `__all__` 对应条目
+- `src/pyflowx/graph.py`:删 `from_yaml` 类方法(若存在)
+- `src/pyflowx/cli/pf.py`:
+  - `_TOOL_ALIASES` 保留 57 个别名(值已是工具名,无 .yaml 含义)
+  - `_run_yaml` → `_run_tool`:`importlib.import_module(f"pyflowx.ops.{tool_name}")` 触发 `@px.tool` 注册 → `from pyflowx.tools import run_tool; return run_tool(tool_name, argv)`
+  - `_LEGACY_TOOLS` 删 `yamlrun`(保留 `emlman`/`profiler`/`pxp`)
+  - `_list_tools` 改为遍历 `_TOOL_REGISTRY` 取 description
+  - `_tool_description` 删除(不再读 YAML)
+- `src/pyflowx/ops/__init__.py`:从导入 6 个功能模块改为导入 22 个工具模块
+- `pyproject.toml`:
+  - `[project.scripts]` 删 `yamlrun`
+  - `[project] dependencies` 删 `pyyaml>=6.0.1`
+  - `[project.optional-dependencies] dev` 删 `types-PyYAML>=6.0.12`
+- `src/pyflowx/yaml_loader.py` 内 `import pyflowx.ops.*` 触发注册的副作用:迁移后由 `pf.py` 的 `importlib.import_module` 显式触发
+
+**全局检查**:
+- `Grep` 全局 `import yaml`、`load_yaml`、`run_cli`、`run_yaml`、`register_fn`、`get_fn`、`has_fn`、`FnRegistry`、`YamlLoadError`、`build_cli_parser`、`parse_yaml_string`、`from_yaml`、`yamlrun`,确认无残留引用
+- `uv run ruff check .` + `uv run pyrefly check .` 通过
+
+### 阶段6:补充测试 + 覆盖率达标
+
+**扩展 `tests/test_tools.py`**:
+- 阶段1 已覆盖核心分支,本阶段补齐阶段2-4 迁移中发现的边界(如 `cwd` 从 CLI 透传、`env`/`retry`/`timeout` 透传 TaskSpec、`_has_function_logic` 对 async 函数/类方法、`_unwrap_optional` 对 `X | None`(3.10+) 等)
+- 阶段1 后若 `tools.py` 覆盖率未达 95%,本阶段补齐
+
+**新增 `tests/cli/test_pf_routing.py`**:
+- 测试 `PfApp` 路由:已知别名 → `_run_tool`、legacy → `_run_legacy`、未知 → 退出码 1
+- 测试 `_list_tools` 输出格式
+
+**更新 `tests/cli/test_*.py`**(16 个):
+- 阶段2-4 已更新 import 路径,本阶段补充通过 `run_tool(...)` 或 `PfApp([tool, subcommand]).run()` 的端到端测试
+- 删除 `tests/test_yaml_loader.py`、`tests/test_registry.py`(若纯 register_fn 测试)
+
+**覆盖率验证**:
+```bash
+uv run pytest --cov=pyflowx --cov-branch --cov-report=term-missing
+```
+- 目标:`pyflowx.tools` ≥95%、整体 ≥95%(branch)
+- 若 `ops/<tool>.py` 因跨平台分支未覆盖,补 mock 测试(`Constants.IS_LINUX`/`IS_WINDOWS`)
+
+**最终门禁**:
+```bash
+uv run ruff check . && uv run ruff format --check .
+uv run pyrefly check .
+uv run pytest --cov=pyflowx --cov-branch --cov-report=term-missing
+```
+全部门禁通过,覆盖率 ≥95%。
+
+## Assumptions & Decisions
+
+1. **tools.py 实现不重写**:已存在的 `tools.py` 经审查实现完整,本计划仅补测试,不改实现(除非测试发现 bug)
+2. **函数体保持不变**:迁移仅改装饰器(`@px.register_fn` → `@px.tool`)与文件位置,函数体逻辑、签名、类型注解保持不变,最大化测试兼容
+3. **CLI 兼容**:57 个 pf 别名不变、子命令名不变、参数名(snake_case → kebab-case)不变、全局选项保留、退出码三态保留
+4. **cmd 任务改 fn 模式**:`piptool i`/`autofmt fmt` 等原 `cmd+${VAR}` 改为函数体内 `subprocess.run`,失去 cmd 任务的 verbose 输出,但模型更统一;verbose 由函数内 `print` 补偿
+5. **聚合任务判定**:`_has_function_logic` 用 ast 分析函数体(pass/.../docstring 视为无逻辑),迁移时聚合任务的函数体写 `pass`
+6. **ops 重组**:6 功能模块 → 22 工具模块,跨工具复用函数(如 `add_date_prefix` 被 filedate 用)放 `ops/_common.py`;未被 YAML 引用的约 20 个 `register_fn` 辅助函数(如 `get_file_timestamp`/`has_files`)去掉装饰器降级为模块级私有
+7. **register_fn 移除时机**:阶段5 统一移除,避免阶段2-4 迁移中破坏未迁移工具
+8. **pyyaml 依赖移除**:阶段5 从 `pyproject.toml` 删除,需确认无其他模块隐式依赖(全局 grep `import yaml` 验证)
+9. **测试更新策略**:阶段2-4 每阶段更新对应 cli 测试 import,阶段6 补充端到端测试;`tests/test_yaml_loader.py` 阶段5 删除
+
+## Verification Steps
+
+每阶段结束运行:
+```bash
+uv run ruff check . && uv run ruff format --check .
+uv run pyrefly check .
+uv run pytest tests/ --cov=pyflowx --cov-branch --cov-report=term-missing -x
+```
+
+端到端验证(阶段4 后):
+```bash
+pf clr                                    # 单命令
+pf which python                           # 单命令 + positional
+pf pdftool m a.pdf b.pdf --output merged.pdf   # 多 subcommand + positional nargs+
+pf pdftool --list                         # --list 输出
+pf pymake tc                              # DAG + 聚合 + 内部 job(hidden)
+pf pymake b --cwd /tmp                    # cwd CLI 透传
+pf envdev --python-mirror aliyun          # 跨平台 fn
+pf gittool a -m "msg"                     # fn subcommand
+pf                                        # 列出所有工具(从 _TOOL_REGISTRY)
+pf unknown_tool                           # 退出码 1
+```
+
+阶段5 后全局清理验证:
+```bash
+# 无残留 YAML 引用
+grep -r "import yaml" src/ tests/ || echo "OK"
+grep -r "load_yaml\|run_cli\|register_fn\|YamlLoadError" src/ tests/ || echo "OK"
+```
