 Codex 的认证和会话状态都来自 `CODEX_HOME`。`cdxs` 做的是在这个目录外面加一层可操作的管理能力：
 
 - 账号管理：导入已有 `auth.json`，通过 OAuth 或 API Key 登录，切换当前账号，并在需要时刷新 OAuth token。
-- 配额查看：查询 OAuth 账号的 Codex 使用配额，并缓存到本地。
+- 配额缓存：列出账号时自动刷新过期的 OAuth 配额缓存。
 - Home 管理：创建命名的 `CODEX_HOME`，并绑定到指定账号。
-- 命令运行：用指定账号或 home 启动子进程，只为该进程设置 `CODEX_HOME`。
+- 命令运行：用指定账号或 home 运行 `codex exec`，只为该进程设置 `CODEX_HOME`。
 - 会话管理：查看会话、统计 token 和文件信息、移入可恢复垃圾箱、恢复会话、修复缺失的会话索引。
 - 线程同步：在多个受管理 home 之间补齐缺失的会话线程。
 - 状态同步：运行轻量 HTTP 服务，在多台机器之间推送或拉取账号状态。

 ## 常用快捷命令
 
-- `cdxs list`：列出账号，并自动刷新过期配额缓存。
-- `cdxs show`：列出账号，但不请求配额接口。
+- `cdxs`：列出账号，并自动刷新过期配额缓存。
+- `cdxs -f`：强制刷新账号配额后再列出。
+- `cdxs show <账号>`：显示单个账号详情，等价于 `cdxs account show <账号>`。
 - `cdxs alias set <别名> <账号>`：给任意 OAuth 或 API Key 账号设置别名。
 - `cdxs alias list`：列出所有账号别名。
 - `cdxs alias remove <别名或账号>`：删除指定账号的别名。
 - `cdxs switch`：不带参数时自动选择可用配额最优的账号。
 - `cdxs switch <账号或别名>`：切换到指定账号，OAuth 和 API Key 账号都可通过 alias 切换。
 - `cdxs switch A --model <model> --effort <effort> --name OpenAI`：切换时更新该账号默认模型、思考程度；`--name` 仅用于 API 模式的 provider name。
-- `cdxs ping`：以 5 并发 ping 所有 OAuth 账号，运行最低 reasoning 的最小 `codex exec`，触发 Codex 侧额度状态刷新。
-- `cdxs ping --account <账号>`：指定账号运行最小 `codex exec`；可重复传多个账号。
+- `cdxs exec <账号> -- --model gpt-5 "hello"`：用指定账号运行 `codex exec`。
+- `cdxs exec <home> --home --temp -- --model gpt-5 "hello"`：基于指定受管 home 建立一次性临时 `CODEX_HOME` 后运行 `codex exec`。
 - `cdxs login --api <key> --base-url <url> --alias A --model <model> --name OpenAI --switch`：保存 API Key 账号并可选切换；`base-url` 为空时使用 OpenAI 默认 API。
 - `cdxs login api --key <key> --base-url <url> --alias A --model <model> --name OpenAI --switch`：同上，保留旧的子命令形式。
 - `cdxs remove <账号>`：删除账号，等价于 `cdxs account remove <账号>`。
