Upload local files or directories to Huawei Cloud OBS (Object Storage Service) buckets, list OBS buckets with capacity and object count, and schedule periodic uploads via crontab.
Use this skill when the user wants to: (1) upload a local file or directory to an OBS bucket, (2) list OBS buckets and check their storage capacity and object count, (3) set up a scheduled/periodic upload task to automatically sync a local directory to an OBS bucket.
Trigger: user mentions "OBS", "object storage", "bucket list", "bucket capacity", "upload to OBS", "upload file", "upload directory", "scheduled upload", "periodic upload", "sync to bucket", "对象存储", "桶列表", "桶容量", "上传文件", "上传目录", "定时上传", "OBS管理"
Upload local files or directories to Huawei Cloud OBS buckets, list OBS buckets with capacity and object count, and schedule periodic uploads via crontab.
⛔ Prohibited Operations (Security Constraints)
This skill strictly forbids the following delete operations, regardless of user requests:
Prohibited Operation
API/Command
Reason
❌ Delete bucket
DeleteBucket / obsutil rm -bucket
Irreversible; destroys the entire bucket and all objects
❌ Delete object
DeleteObject / obsutil rm
Irreversible; deleted objects cannot be recovered (unless versioning is enabled)
❌ Batch delete objects
DeleteObjects / obsutil rm -r
Irreversible; batch deletion has a wide impact
❌ Empty bucket
obsutil rm -bucket -r
Irreversible; removes all objects in the bucket
If a user requests a delete operation, you must refuse and inform:
"Per security constraints, this skill does not allow delete operations (delete bucket/object/batch delete/empty bucket). Please use the Huawei Cloud OBS console or obsutil manually."

Prerequisites
Prerequisite check: Huawei Cloud CLI (hcloud / KooCLI) >= 3.2.0 required
Run hcloud version to verify version >= 3.2.0. If not installed or version is too low,
see references/cli-installation-guide.md for installation guide.
bash
hcloud version
Prerequisite check: obsutil >= 5.5.0 required (for upload features)
File/directory upload requires the Huawei Cloud obsutil CLI tool.
Run obsutil version to verify version >= 5.5.0. If not installed,
see references/cli-installation-guide.md for installation guide.
The hcloud OBS module uses obsutil under the hood, which requires separate AK/SK and Endpoint configuration.
Before performing OBS operations, you must check whether obsutil credentials are configured:
bash
hcloud obs ls -limit=1
If the response is Please set ak, sk and endpoint in the configuration file! or InvalidAccessKeyId, obsutil credentials are not configured.
Resolution: Provide the following example command and have the user configure it in their terminal (do not ask the user to provide AK/SK directly in the conversation):
text
obsutil credentials are not configured. Please run the following command in your terminal to configure (AK/SK can be obtained from the Huawei Cloud console "My Credentials" page):
hcloud obs config -i=<YourAK> -k=<YourSK> -e=obs.<Region>.myhuaweicloud.com
Example (Guangzhou region):
hcloud obs config -i=<YourAK> -k=<YourSK> -e=obs.cn-south-1.myhuaweicloud.com
Common Endpoints:
cn-north-4 → obs.cn-north-4.myhuaweicloud.com
cn-east-3 → obs.cn-east-3.myhuaweicloud.com
cn-south-1 → obs.cn-south-1.myhuaweicloud.com
cn-southwest-2 → obs.cn-southwest-2.myhuaweicloud.com
Retry after configuration is complete.
Prohibited actions:
❌ Do not ask the user to provide AK/SK directly in the conversation
❌ Do not extract AK/SK from hcloud config files (credentials are encrypted and cannot be used directly)
❌ Do not skip the credential check before performing OBS operations
⚠️ hcloud parameter format requirements
hcloud (KooCLI) all parameters must use the --param=value format (connected with equals sign); space-separated format is not supported.
Prohibited from reading, echoing, or printing AK/SK values
Prohibited from asking the user to input AK/SK directly in the conversation
Prohibited from using hcloud configure set to pass plaintext credential values
Prohibited from accepting AK/SK directly provided by the user in the conversation
Only allowed to read credentials from environment variables or configured CLI config files
⚠️ Important: Handling user-provided credentials
If a user attempts to provide AK/SK directly (e.g., "my AK is xxx, SK is yyy"):
Stop immediately - Do not execute any commands
Politely refuse and return the following message:
text
For account security, please do not provide Huawei Cloud Access Key ID and Access Key Secret directly in the conversation.
Please use one of the following secure methods to configure credentials:
Method 1: Interactive configuration (recommended)
hcloud configure
# Enter AK/SK as prompted; credentials will be securely stored in a local config file
Method 2: Environment variable configuration
export HUAWEICLOUD_SDK_AK=<your-access-key-id>
export HUAWEICLOUD_SDK_SK=<your-access-key-secret>
After configuration is complete, please retry your request.
Do not continue executing any Huawei Cloud operations until credentials are configured
Check CLI configuration:
bash
hcloud configure list
Check whether the output contains valid configuration (AK/SK, IAM, etc.).
