dvcrn Qiniu Cloud Storage Management (qshell)
This skill wraps the qshell CLI to let you manage Qiniu Kodo storage through natural language. It handles prerequisite checks, command selection, and result formatting automatically.
Pre-flight Checks
Before executing any storage operation, run these checks in order. The reason for checking every time is that qshell state can change between sessions (uninstalled, credentials expired), and failing silently leads to confusing errors.
1. Installation Check
qshell --version
If this fails, the user doesn't have qshell installed. Stop and guide them through installation (see references/install-guide.md).
2. Authentication Check
qshell user ls
If the output is empty or shows an error, the user needs to configure credentials:
qshell account <AccessKey> <SecretKey> <Name>
Direct them to Qiniu Key Management to get their AK/SK.
3. Proceed with the Request
Once both checks pass, execute the user's request using the command reference below.
Command Reference
Uploading Files
Choose the upload method based on what the user provides:
- Single file, under 100MB:
qshell fput [--overwrite] <Bucket> <Key> <LocalFile> - Single file, 100MB or larger:
qshell rput [--overwrite] <Bucket> <Key> <LocalFile>— rput uses resumable upload, so if it fails partway through, re-running the same command resumes from where it left off rather than starting over. - Entire directory:
qshell qupload2 --src-dir=<Dir> --bucket=<Bucket> [--overwrite] [--key-prefix=<Prefix>] [--thread-count=<N>]— if some files fail during batch upload, qupload2 logs failures to a local file. Re-running the same command retries only the failed files.
To decide which to use: check the file size first (ls -lh <file>). If the user points to a directory rather than a file, use qupload2.
Key (remote path) inference: When the user doesn't specify a remote path, use the local filename as the Key. If they mention a remote directory like images/, concatenate it as images/filename.ext.
After a successful upload: Run qshell domains <Bucket> to get the bound domain, then show the user the full access URL: http(s)://<Domain>/<Key>. Prefer CDN domains when multiple domains are available.
Downloading Files
- Single file:
qshell get <Bucket> <Key> [-o <SaveAs>] - Batch download: Requires a config file. See
references/batch-download.mdfor the JSON format.
File Operations
| Operation | Command |
|---|---|
| List files | qshell listbucket2 <Bucket> [--prefix <P>] [--limit <N>] [--marker <M>] |
| File info | qshell stat <Bucket> <Key> |
| Delete file | qshell delete <Bucket> <Key> |
| Copy file | qshell copy <SrcBucket> <SrcKey> <DstBucket> [-k <DstKey>] |
| Move/rename | qshell move <SrcBucket> <SrcKey> <DstBucket> [-k <DstKey>] |
When listing files, use --limit 20 by default to keep output manageable. However, if the user explicitly asks for "all" files or a large number, omit the limit or set a high value to respect their intent.
Before deleting: Always run qshell stat first and show the file details to the user. Wait for explicit confirmation before executing qshell delete. This prevents accidental data loss — deleted files in Kodo cannot be recovered without versioning enabled.
Bucket Management
| Operation | Command |
|---|---|
| List buckets | qshell buckets |
| Bucket domains | qshell domains <Bucket> |
| Create bucket | qshell mkbucket <Bucket> --region <Region> |
Region values: z0 (East China), z1 (North China), z2 (South China), na0 (North America), as0 (Southeast Asia), cn-east-2 (East China - Zhejiang 2)
CDN and Network
| Operation | Command |
|---|---|
| Fetch URL to bucket | qshell fetch <URL> <Bucket> <Key> |
| CDN refresh URLs | qshell cdnrefresh -i <file> |
| CDN refresh dirs | qshell cdnrefresh -r -i <file> |
| CDN prefetch | qshell cdnprefetch -i <file> |
| Private download URL | qshell privateurl <PublicUrl> [--deadline <timestamp>] |
Error Recovery
When a command fails, diagnose and guide the user rather than just showing the raw error:
| Error pattern | What happened | What to do |
|---|---|---|
no such file or directory |
Local file path is wrong | Help the user verify the path exists |
invalid account / no auth |
Credentials missing or expired | Re-run qshell account |
no such bucket |
Bucket name doesn't exist | Run qshell buckets to show available ones |
file exists |
Remote file already exists | Ask if they want to add --overwrite |
key doesn't exist |
Remote key not found | Use qshell listbucket2 to find the correct key |
bad token / expired token |
Auth token expired | Re-run qshell account |
| Network timeout | Connectivity issue | Suggest checking network and retrying |

Examples
Example 1:
Input: "Upload ./logo.png to my-bucket"
Steps: Check file size -> qshell fput my-bucket logo.png ./logo.png -> qshell domains my-bucket -> Return URL
Example 2:
Input: "List all jpg files in my-bucket"
Steps: qshell listbucket2 my-bucket --limit 100 -> Filter results for .jpg suffix -> Display
Example 3:
Input: "Delete old-file.txt from my-bucket"
Steps: qshell stat my-bucket old-file.txt -> Show file info -> Wait for user confirmation -> qshell delete my-bucket old-file.txt
