环境探测 JSON 协议

probe.sh / probe.ps1 / probe-python.sh / probe-node.sh 输出统一 JSON。Skill 解析 JSON 后再决策，避免逐条 grep。

通用字段

字段	类型	说明
platform	"darwin" | "linux" | "win32"	操作系统标识
arch	"arm64" | "x64" | ...	CPU 架构
desirecore_api	string	探测到的 DesireCore agent-service URL，不可达时为 ""
desirecore_port_file	string	~/.desirecore/agent-service.port 是否存在

probe.sh / probe.ps1（父级 dev-environment-setup）

输出系统级总览：

{
  "platform": "darwin",
  "arch": "arm64",
  "desirecore_api": "https://127.0.0.1:38291",
  "desirecore_port_file": true,
  "tools": {
    "python3": { "available": true, "path": "/opt/homebrew/bin/python3", "version": "3.12.4" },
    "pip3":    { "available": true, "path": "/opt/homebrew/bin/pip3",    "version": "24.0" },
    "node":    { "available": true, "path": "/opt/homebrew/bin/node",    "version": "22.4.1" },
    "npm":     { "available": true, "path": "/opt/homebrew/bin/npm",     "version": "10.8.1" },
    "docker":  { "available": false },
    "podman":  { "available": false },
    "git":     { "available": true, "path": "/usr/bin/git", "version": "2.43.0" }
  },
  "wsl": null
}

Windows 上 wsl 字段值类似 { "installed": true, "version": "2", "defaultDistro": "Ubuntu" }。

probe-python.sh（python-runtime 专用）

{
  "platform": "darwin",
  "arch": "arm64",
  "desirecore_api": "https://127.0.0.1:38291",
  "system_python": { "path": "/opt/homebrew/bin/python3", "version": "3.12.4" },
  "system_pip": { "path": "/opt/homebrew/bin/pip3", "version": "24.0" },
  "hatch_path": "/Users/wangyi/.desirecore/runtime/hatch/hatch",
  "hatch_version": "1.16.5",
  "hatch_versions": ["3.11", "3.12"],
  "active_venv": "/Users/wangyi/proj/.venv",
  "pep668": false,
  "pyenv_path": "",
  "conda_path": ""
}

字段语义：

• hatch_path 空字符串表示二进制不存在
• hatch_versions 是 ~/.desirecore/runtime/hatch/local/ 下的目录列表（即已通过 Hatch 安装的 Python 版本）
• active_venv 取自 $VIRTUAL_ENV 环境变量
• pep668 检测 /usr/lib/python*/EXTERNALLY-MANAGED 是否存在（Debian 12+/Ubuntu 23.04+ 启用）

probe-node.sh（nodejs-runtime 专用）

{
  "platform": "darwin",
  "arch": "arm64",
  "desirecore_api": "https://127.0.0.1:38291",
  "system_node": { "path": "/opt/homebrew/bin/node", "version": "22.4.1" },
  "system_npm":  { "path": "/opt/homebrew/bin/npm",  "version": "10.8.1" },
  "volta_path": "/Users/wangyi/.desirecore/runtime/volta/volta",
  "volta_version": "2.0.2",
  "volta_tools": {
    "node": ["22.4.1"],
    "pnpm": ["9.5.0"],
    "yarn": [],
    "npm":  []
  },
  "package_json_volta": null,
  "nvm_path": "",
  "fnm_path": "",
  "registry": "https://registry.npmmirror.com/",
  "proxy": ""
}

字段语义：

• volta_tools 来自 <volta> list --format=plain，按工具分类
• package_json_volta 若当前目录存在 package.json 且其中有 "volta" 字段，填入对象；否则 null
• registry / proxy 来自 npm config get registry / npm config get https-proxy

设计约定

1. JSON 必合法：缺字段也保留键并赋空字符串/null，避免 Claude 解析失败。
2. 不阻塞：每个外部命令都加 2>/dev/null，失败用空值，不让脚本中途退出。
3. 超时控制：HTTP 探测 0.5s 超时；CLI 调用最长 5s。
4. 跨平台：probe.sh / probe-python.sh / probe-node.sh 共用 POSIX 子集；Windows 同等功能由 probe.ps1 提供（仅父级提供，python/nodejs 子 skill 可由 PowerShell 直接 invoke 父级或自行实现）。
5. 路径展开：所有 ~ 在 JSON 中展开为绝对路径，避免下游解析歧义。

调用约定

SNAPSHOT=$(bash skills/python-runtime/scripts/probe-python.sh)
echo "$SNAPSHOT" | jq .

# 关键字段判定
HATCH=$(echo "$SNAPSHOT" | jq -r .hatch_path)
[ -n "$HATCH" ] && [ "$HATCH" != "null" ] && echo "Hatch 可用"

PowerShell 等价：

$snapshot = & "$PWD\skills\dev-environment-setup\scripts\probe.ps1" | ConvertFrom-Json
if ($snapshot.tools.node.available) { ... }
