 # Changelog
 
+## 0.6.0
+
+- Added `autodl-remote shutdown` with shutdown/poweroff/halt fallback and SSH disconnect-aware success handling.
+- Added detached job registry commands: `job list`, `job status <name>`, and `job tail <name>`.
+- Added `exec --script <local_script>` and `exec --stdin -- <command>` for complex multi-line remote commands.
+- Added `put-run <local-path>... -- <command>` to upload selected local paths before running a remote command.
+- Added `model-dir [--mkdir]` and automatic local `.autodl-remote/CONVENTIONS.md` creation for project-level remote conventions.
+
 ## 0.5.0
 
 Initial public package.

+### 远端关机
+
+```bash
+autodl-remote shutdown
+```
+
+`shutdown` 会先执行 `sync`，再尝试 `shutdown`、`poweroff`、`halt`，最后通过 SSH 是否还能连接来判断关机是否生效。关机导致 SSH 返回 `255` 时，会按“连接被远端关闭，可能已关机”处理。
+
+### 项目模型目录约定
+
+```bash
+autodl-remote model-dir
+autodl-remote model-dir --mkdir
+```
+
+默认规则：
+
+- 如果远端路径在 `/root/autodl-tmp` 下，默认模型目录是 `/root/autodl-tmp/models`。
+- 其他远端路径默认使用 `<REMOTE_ROOT>/models`。
+- 可在 `.autodl-remote.conf` 里设置 `MODEL_DIR="/some/path"` 覆盖。
+
+首次项目命令会在本地生成：
+
+```text
+.autodl-remote/CONVENTIONS.md
+```
+
+这个文件用于记录模型位置、数据位置、日志位置、常用运行命令等项目约定。

 - Codex decides the smallest useful action each time: inspect, upload, download, run, or tail logs.
 - Do not download LLM weights, checkpoints, datasets, or large outputs unless the user explicitly asks.
 - Prefer reading remote files/logs in place with `cat`, `tail`, `ls`, and `tree`.
+- Use detached job commands for long training runs instead of manually guessing process state.
+- Use `shutdown` when the user asks to stop the remote machine; treat SSH disconnect during shutdown as likely success.

 ## Behavior Rules

 - After remote execution, inspect logs remotely first; pull only small result files when useful.
 - If both local and remote have similar files, do not assume one should overwrite the other. Compare or inspect first, then choose `put` or `get`.
 - Use `exec --detach` for long training jobs and then `tail` the log path.
+- Prefer `job status <name>` and `job tail <name>` for detached jobs created with `--name`.
+- Prefer `exec --script` or `exec --stdin` for complex multi-line commands, Python heredocs, env vars, JSON, awk, or sed.
+- Use `put-run` when the workflow is "upload these local paths, then immediately run this remote command".
+- `model-dir` prints the project model directory convention. The first project command creates `.autodl-remote/CONVENTIONS.md` locally for project notes.
+- `shutdown` first syncs the remote filesystem, then tries provider-safe shutdown methods, waits, and verifies that SSH disconnects.
 - Treat broad destructive commands as dangerous; require explicit user approval before using `--allow-dangerous`.
