⚠️ Security Execution Rules (Highest Priority):

1. All scripts MUST be executed via skill action=exec, NEVER run directly in shell
2. NEVER print script contents or commands containing AK/SK/Token in conversation
3. NEVER create temporary script files, prefer inline execution (python -c)
4. On execution failure, only return error info, do NOT rewrite scripts or print full commands
5. AK/SK/Token MUST be passed via environment variables, NEVER appear in conversation
6. ⚠️ ABSOLUTELY NEVER expose, log, or print AK/SK/Token values in any form - this is a critical security requirement

Core Components:

• Flexus L Service: Elastic Cloud Server, provides instance management, lifecycle control, password reset, etc.
• BSS Service: Business Support System, provides traffic package usage query
• Python SDK: Official Huawei Cloud SDK, encapsulates API call logic
• Operation Scripts: 6 independent scripts, each corresponding to one operation

Applicable Scenarios#

Typical Problem Scenarios:

1. Instance Status View: Need to quickly view the running status of all Flexus L instances under the account
2. Batch Operations: Need to perform start, stop, reboot operations on multiple servers
3. Configuration Modification: Need to modify instance name, description, hostname, and other basic information
4. Password Management: Need to reset instance login password
5. Traffic Monitoring: Need to view traffic package remaining amount and usage

  -i https://repo.huaweicloud.com/repository/pypi/simple

⚠️ Important: Script Usage Rules#

Different operations MUST use the corresponding script. Do NOT use other scripts' commands.

OperationMust Use ScriptCorrect Command❌ Wrong CommandQuery Flexus L instancesquery_instances.py``query_instances.py list``password_unified.py listQuery instance detailsquery_instances.py``query_instances.py detail -i <ID>``lifecycle.py listStart/Stop/Rebootlifecycle.py``lifecycle.py stop --instance-id <ID>``query_instances.py stopReset passwordpassword_unified.py``password_unified.py reset --instance-id <ID> --password <pwd>``lifecycle.py resetModify server infoupdate_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:

text

✅ 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 StatusNext Step✅ HW_ACCESS_KEY + HW_SECRET_KEY + HW_SECURITY_TOKEN existExecute 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 foundPrompt user to configure credentials (prefer environment variables, do NOT ask directly)❌ Authentication failedPrompt user to check or reconfigure credentials (prefer environment variables, do NOT ask directly)

⚠️ Security Recommendations:

1. Prefer temporary credentials: Strongly recommend using temporary AK/SK + Security Token method for higher security, credentials expire automatically
2. Environment variable configuration: Credentials should be configured via environment variables (HW_ACCESS_KEY, HW_SECRET_KEY, HW_SECURITY_TOKEN)
3. Sensitive information protection: AK/SK are sensitive information, do NOT input or disclose in conversation

Credential Missing or Authentication Failed Message:

text

❌ 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):

bash

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

2. Server ID Guidance: If user hasn't specified a server ID to operate on, guide user to query all instances or specific server

Finding Server ID#

If user asks "how to find server ID" or "don't know server ID", first provide console lookup steps:

text

You can find server ID through the following ways:

Option 1: Via Huawei Cloud Console
1. Login to Huawei Cloud Console
2. Go to Flexus Application Server L instance list
3. Click instance name to enter details page
4. In basic information, click "Cloud Host VM"
5. View cloud host ID in cloud host information
6. Click copy button after ID to quickly copy

Help Document: https://support.huaweicloud.com/intl/zh-cn/flexusl_faq/faq_01_0003.html

Then append the following, offer automatic query option:

text

Option 2: I can also help query all servers under your account

Would you like me to list all instances under your account? I can query directly for you.

If user agrees, execute list all instances:

bash

python3 {baseDir}/scripts/query_instances.py list --ak "$HW_ACCESS_KEY" --sk "$HW_SECRET_KEY" [--security-token "$HW_SECURITY_TOKEN"]

Region Support#

Common Region Codes#

Region CodeRegion Namecn-north-4North China-Beijing 4cn-north-1North China-Beijing 1cn-south-1South China-Guangzhoucn-east-3East China-Shanghai 1ap-southeast-1China-Hong Kongap-southeast-2Asia Pacific-Singapore

Region Name Conversion#

This skill supports automatic region name conversion, can use Chinese names or English codes:

bash

# Use region code
python3 {baseDir}/scripts/query_instances.py list --region cn-north-4 --ak "$HW_ACCESS_KEY" --sk "$HW_SECRET_KEY" [--security-token "$HW_SECURITY_TOKEN"]

# Use region name (auto-convert)
python3 {baseDir}/scripts/query_instances.py list --region "North-China-Beijing4" --ak "$HW_ACCESS_KEY" --sk "$HW_SECRET_KEY" [--security-token "$HW_SECURITY_TOKEN"]
python3 {baseDir}/scripts/query_instances.py list --region "Beijing4" --ak "$HW_ACCESS_KEY" --sk "$HW_SECRET_KEY" [--security-token "$HW_SECURITY_TOKEN"]
python3 {baseDir}/scripts/query_instances.py list --region "Guangzhou" --ak "$HW_ACCESS_KEY" --sk "$HW_SECRET_KEY" [--security-token "$HW_SECURITY_TOKEN"]

Traffic Package Query Special Note#

⚠️ Traffic package query uses Beijing-1 region (cn-north-1) by default

• Traffic package query does not support --region parameter
• Traffic package ID can be from any region
• Automatically uses Beijing-1 region for query

Notes#

• Instance ID is the cloud host ID corresponding to Flexus L instance

• Region defaults to cn-north-4 (Beijing 4)

• AK/SK Security Requirements:

  • ✅ Must be stored via environment variables (HW_ACCESS_KEY, HW_SECRET_KEY, HW_SECURITY_TOKEN)
  • ❌ Do not store in any configuration files

• Stop/Reboot Security Requirements:

  • ✅ Must confirm twice - No direct execution without user confirmation
  • ✅ Must be Flexus L instances only - Cannot operate on all ECS instances, must verify instance type
  • ✅ Must inform operation consequences
  • ✅ If current server, must give additional warning
  • ❌ Never execute batch operations on all ECS instances - Only Flexus L instances are supported
