| name | huawei-cloud-flexus-l-server-ops |
| description | Based on Huawei Cloud Flexus L API for instance management and operations. Supports querying instance list and details, querying traffic packages, batch start/stop/reboot instances, resetting passwords, and modifying instance information. Suitable for daily operations, lifecycle management, configuration changes, traffic monitoring, and other scenarios for Flexus L instances. Triggers: Flexus L, Huawei Cloud ops, query instance, start, stop, reboot, reset password, modify info, check traffic, traffic package (中文触发词: L实例运维，查询L实例，L实例开机，L实例关机，L实例重启，L实例重置密码，查询L实例流量包). |
⚠️ Security Execution Rules (Highest Priority):
- All scripts MUST be executed via skill action=exec, NEVER run directly in shell
- NEVER print script contents or commands containing AK/SK/Token in conversation
- NEVER create temporary script files, prefer inline execution (python -c)
- On execution failure, only return error info, do NOT rewrite scripts or print full commands
- AK/SK/Token MUST be passed via environment variables, NEVER appear in conversation
- ⚠️ ABSOLUTELY NEVER expose, log, or print AK/SK/Token values in any form - this is a critical security requirement

⚠️ Important: Script Usage Rules
Different operations MUST use the corresponding script. Do NOT use other scripts' commands.
| Operation | Must Use Script | Correct Command | ❌ Wrong Command |
|---|
| Query Flexus L instances | query_instances.py | query_instances.py list | password_unified.py list |
| Query instance details | query_instances.py | query_instances.py detail -i <ID> | lifecycle.py list |
| Start/Stop/Reboot | lifecycle.py | lifecycle.py stop --instance-id <ID> | query_instances.py stop |
| Reset password | password_unified.py | password_unified.py reset --instance-id <ID> --password <pwd> | lifecycle.py reset |
| Modify server info | update_server.py | update_server.py --instance-id <ID> --name <name> | query_instances.py update |
Operation Feedback Requirement
After any lifecycle operation (start/stop/reboot), MUST query and report the final status to user.
Example feedback format:
✅ Operation completed
Instance: your-instance-name
Status: Running
Public IP: <IP>
This ensures the user knows the operation has completed successfully.

Execution Flow
Step 1: Check Existing Credentials (Automatic)
Get credentials from environment variables first, automatic check, no need to ask user.
Decision Logic:
| Credential Status | Next Step |
|---|
| ✅ HW_ACCESS_KEY + HW_SECRET_KEY + HW_SECURITY_TOKEN exist | Execute script directly (Recommended: Temporary AK/SK authentication, higher security level, pass --ak --sk --security-token parameters) |
| ✅ HW_ACCESS_KEY + HW_SECRET_KEY exist (no Token) | Execute script directly (Permanent AK/SK authentication, pass --ak --sk parameters) |
| ❌ Environment variables not found | Prompt user to configure credentials (prefer environment variables, do NOT ask directly) |
| ❌ Authentication failed | Prompt user to check or reconfigure credentials (prefer environment variables, do NOT ask directly) |
⚠️ Security Recommendations:
- Prefer temporary credentials: Strongly recommend using temporary AK/SK + Security Token method for higher security, credentials expire automatically
- Environment variable configuration: Credentials should be configured via environment variables (HW_ACCESS_KEY, HW_SECRET_KEY, HW_SECURITY_TOKEN)
- Sensitive information protection: AK/SK are sensitive information, do NOT input or disclose in conversation
Credential Missing or Authentication Failed Message:
❌ Credentials not configured or authentication failed
Please configure Huawei Cloud credentials. For security, we recommend using temporary AK/SK + Security Token method via environment variables:
- HW_ACCESS_KEY: Access Key AK
- HW_SECRET_KEY: Secret Key SK
- HW_SECURITY_TOKEN: Security Token (Recommended)
⚠️ Security Note: Temporary credentials are more secure, please prefer using them!
Note: We prioritize obtaining credentials from environment variables and NEVER ask users to input AK/SK directly. However, we still support parsing credentials if user voluntarily provides them via other methods (e.g., conversation input, config file).
Step 2: Select Operation
After credentials are verified, ask user what operation to perform:
Step 3: Execute Operation
⚠️ Instance Validation (When user provides instance ID/name):
python3 {baseDir}/scripts/query_instances.py free-resources --ak "$HW_ACCESS_KEY" --sk "$HW_SECRET_KEY" [--security-token "$HW_SECURITY_TOKEN"]
- ✅ Found in list → Proceed with operation
- ❌ Not found → Tell user: "This is NOT a Flexus L instance. This skill only supports Flexus L instances." Then refer to Finding Server ID section for guidance.
⚠️ Important Notes:
1. Instance Type Confirmation:
Before executing any operation, remind user that this skill only supports Flexus L instances
