 ## 覆盖语义
 
 `--if-exists=overwrite` 走 `POST /open-apis/drive/v1/files/upload_all`，并在 form 中带上现有文件的 `file_token`，由后端原地更新内容并返回新版本号。`items[].version` 字段会回填该版本号。
 
+`--if-exists=smart` 是给“重复跑同步”的场景增加的增量优化：当远端 `modified_time` 在同等时间精度下已经等于或晚于本地 mtime 时，命令会把该文件计为 `skipped`；时间戳缺失、非法或更旧时，则继续走正常上传/覆盖路径。**也就是说，只要 smart 判定“远端不够新”，它就会进入与 `--if-exists=overwrite` 相同的覆盖实现，因此在未 rollout version 字段的 tenant 上仍可能非零失败。**
+
 > **为什么默认是 `skip` 而不是 `overwrite`：** `upload_all` 接受 `file_token` 字段、并在响应里返回 `version` 是设计文档（Drive 同步盘）规定的协议；此后端尚在灰度发布。在还未开通该字段的 tenant 上，`--if-exists=overwrite` 会因"无 version 返回"而把对应文件标成 `failed`，整次 `+push` 也会因此非零退出。所以默认值故意定为 `skip`：第一次往一个已经有内容的目录里 push，不会因为协议没到位就把整次运行打挂；要真的覆盖远端，必须显式带 `--if-exists overwrite`。新建上传不依赖该字段，不受影响。
 
 大文件（>20MB）会自动切到三段式 `upload_prepare` / `upload_part` / `upload_finish`；该路径下 `version` 暂未在响应中返回，覆盖结果中 `items[].version` 会留空，但 `file_token` 与 `action: overwritten` 仍会正确产出。

+
+List groups the current user (or bot, with `--as bot`) is a member of. Useful for enumerating "my chats" without a search keyword, or for bulk operations against the caller's chats. Supports pagination, sort order, and (user identity only) muted-chat filtering.
+
+This skill maps to the shortcut: `lark-cli im +chat-list` (internally calls `GET /open-apis/im/v1/chats`).
+
+## Commands
+
+```bash
+# List the user's chats (default sort: ByCreateTimeAsc)
+lark-cli im +chat-list
+
+# Sort by recent activity (most recently active first)
+lark-cli im +chat-list --sort-type ByActiveTimeDesc
+
+# Limit page size
+lark-cli im +chat-list --page-size 50
+
+# Pagination
+lark-cli im +chat-list --page-token "xxx"
+
+# Drop muted chats (user identity only)
+lark-cli im +chat-list --exclude-muted
+
+# JSON output
+lark-cli im +chat-list --format json
+
+# Preview the request without executing it
+lark-cli im +chat-list --dry-run
+```
+
+## Parameters
+
+| Parameter | Required | Limits | Description |
+|------|------|------|------|
+| `--user-id-type <type>` | No | `open_id` (default), `union_id`, `user_id` | ID type used for `owner_id` in the response |
+| `--sort-type <type>` | No | `ByCreateTimeAsc` (default), `ByActiveTimeDesc` | Result ordering |
+| `--page-size <n>` | No | 1-100, default 20 | Number of results per page |
+| `--page-token <token>` | No | - | Pagination token from the previous response |
+| `--exclude-muted` | No | User identity only | Drop chats the current user has muted (do-not-disturb). Under `--as bot`, the flag is silently inactive; see "Filtering muted chats" below |
+| `--format json` | No | - | Output as JSON |
+| `--dry-run` | No | - | Preview the request without executing it |
+
+> **Note:** Supports both `--as user` (default) and `--as bot`. When using bot identity, the app must have bot capability enabled.
+
+## Output Fields
+
+| Field | Description |
+|------|------|
+| `chat_id` | Chat ID (`oc_xxx` format) |
+| `name` | Chat name |
+| `description` | Chat description |
+| `owner_id` | Owner ID (type controlled by `--user-id-type`) |
+| `external` | Whether the chat is external |
+| `chat_status` | Chat status (`normal` / `dissolved` / `dissolved_save`) |
+
+## Filtering muted chats
+
+`--exclude-muted` (user identity only) drops chats the current user has set to do-not-disturb. After the list call, the CLI batches the page's chat_ids through `POST /open-apis/im/v1/chat_user_setting/batch_get_mute_status` and filters client-side. Under `--as bot`, the mute API is UAT-only and the filter is silently skipped.
+
+When the flag is set, the JSON envelope gains a `filter` sub-object (absent otherwise, so existing consumers are unaffected); `fetched_count == returned_count + filtered_count` always holds:
+
+```json
+{
+  "chats": [...],
+  "filter": {
+    "applied": "exclude_muted",
+    "fetched_count": 20,
+    "returned_count": 17,
+    "filtered_count": 3,
+    "hint": "Filtered out 3 muted chat(s) on this page (17 remaining); use --page-token to fetch more."
+  }
+}
+```
+
+## Usage Scenarios
+
+### Scenario 1: List my recent chats
+
+```bash
+lark-cli im +chat-list --sort-type ByActiveTimeDesc --page-size 10
+```
+
+### Scenario 2: List my non-muted chats sorted by activity
+
+```bash
+lark-cli im +chat-list --sort-type ByActiveTimeDesc --exclude-muted
+```
+
+### Scenario 3: Iterate all my chats programmatically
+
+```bash
+TOKEN=""
+while :; do
+  RESP=$(lark-cli im +chat-list --page-size 100 --page-token "$TOKEN" --format json)
+  echo "$RESP" | jq -r '.data.chats[].chat_id'

+  [ "$HAS_MORE" = "true" ] || break
+  TOKEN=$(echo "$RESP" | jq -r '.data.page_token')
+done
+```
+
+## Common Errors and Troubleshooting
+
+| Symptom | Root Cause | Solution |
+|---------|---------|---------|
+| `--page-size must be an integer between 1 and 100` | page-size is out of range or not an integer | Use an integer between 1 and 100 |
+| Permission denied (99991672) | The bot app does not have `im:chat:read` TAT permission enabled | Enable the permission for the app in the Open Platform console |
+| Permission denied (99991679) with `--as user` | UAT is not authorized for `im:chat:read` | Run `lark-cli auth login --scope "im:chat:read"` |
+| `Bot ability is not activated` (232025) | The app does not have bot capability enabled | Enable bot capability in the Open Platform console |
+| `--exclude-muted` returns all chats unfiltered and `hint` says "no effect under bot identity" | Running under `--as bot` (mute API is UAT-only) | Switch to `--as user` for mute filtering |

 2. **Search scope is limited:** only chats visible to the current user or bot can be found (joined chats plus public chats). This is not a global search over all chats.
 3. **Control result volume:** the result set may be large. Use `--page-size` deliberately.
 4. **Suggest follow-up actions:** after finding a chat, common next steps include listing recent messages (`im +chat-messages-list`) or sending a message (`im +messages-send`).
-5. **NEVER fall back to chats list:** If `+chat-search` returns empty results, do NOT attempt to use `im chats list` or `GET /open-apis/im/v1/chats` as a fallback.

 ## Summary
 - TestDrive_FilesCreateFolderWorkflow: proves `drive files create_folder` in `create_folder as bot`; helper asserts the returned folder token and registers best-effort cleanup via `drive files delete`.
 - TestDrive_StatusWorkflow: proves `drive +status` against a real Drive folder. Seeds the remote side via `drive +upload` (`unchanged.txt`, `modified.txt`, `remote-only.txt`), seeds local files with the matching/diverging contents, and asserts every output bucket (`unchanged`, `modified`, `new_local`, `new_remote`) holds exactly the expected `rel_path` and `file_token`. Cleans up uploaded files and the parent folder via best-effort cleanup hooks.
+- TestDrive_UploadWorkflow: proves `drive +upload` against the real backend in both create and overwrite modes. First uploads a fresh file into a temporary Drive folder, then re-uploads new bytes with `--file-token` against the returned token, asserts the overwrite keeps the token stable, and finally downloads the file to confirm the remote content changed.
 - TestDrive_DuplicateRemoteWorkflow: proves the duplicate-remote workflows against the real backend. One subtest uploads two same-name files into the same Drive folder and asserts `drive +status` and default `drive +pull` both fail with `duplicate_remote_path`, while `drive +pull --on-duplicate-remote=rename` succeeds, downloads both files, and writes a hashed renamed sibling locally. The other subtest uploads duplicate remote files, runs `drive +push --on-duplicate-remote=newest --if-exists=overwrite --delete-remote --yes`, and then re-runs `drive +status` to prove the mirror converged to a single unchanged `dup.txt`.
 - TestDrive_ApplyPermissionDryRun / TestDrive_ApplyPermissionDryRunRejectsFullAccess: dry-run coverage for `drive +apply-permission`; asserts URL→type inference for docx/sheet/slides, explicit `--type` overriding URL inference when both a recognized URL and `--type` are supplied, bare-token + explicit `--type` path, request method/URL/type-query/perm/remark body shape, optional `remark` omission when unset, and client-side rejection of `--perm full_access`.
