## Prerequisites

### 1. Python Environment and dependencies

- Python >= 3.8
- huaweicloudsdkcore >= 3.0.0
- huaweicloudsdkecs >= 3.0.0
- huaweicloudsdkbss >= 3.0.0
- huaweicloudsdkconfig >= 3.0.0
- requests >= 2.31.0

### 2. Install Huawei Cloud SDK

```bash
pip3 install huaweicloudsdkcore huaweicloudsdkecs huaweicloudsdkconfig huaweicloudsdkbss \
  -i https://repo.huaweicloud.com/repository/pypi/simple
```

### 3. Configure AK/SK

**How to Obtain:**

1. Login to Huawei Cloud Console: https://console.huaweicloud.com
2. Click your username in the top right, select "My Credentials"
3. Select "Access Keys" in the left navigation
4. Click "Add Access Key" button
5. Enter verification code to confirm identity
6. System will automatically download a CSV file containing AK/SK
   - **Access Key ID (AK)**: Access key ID, used to identify user
   - **Secret Access Key (SK)**: Secret access key, used to sign requests

**⚠️ Important Notes:**
- SK is only shown once when created, please keep it safe
- If you forget SK, you need to delete the old access key and create a new one
- Each user can create up to 2 access keys
- Regularly rotate access keys for better security

**Configuration:**
```bash
export CLOUD_SDK_AK="your_Access_Key_ID"
export CLOUD_SDK_SK="your_Secret_Access_Key"
```

**⚠️ Security Requirement:** Only set via environment variables temporarily, do not store in any configuration files.

## ⚠️ 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 <ID>` | ~~`query_instances.py stop`~~ |
| Reset password | `password_unified.py` | `password_unified.py reset <ID> <pwd>` | ~~`lifecycle.py reset`~~ |
| Modify server info | `update_server.py` | `update_server.py --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.

## Scripts Description

## Parameters

**Required Parameters:**

| Operation | Required Parameters | Description |
|-----------|---------------------|-------------|
| Query Instance Details | instance-id | Instance ID |
| Start/Stop/Reboot | instance-id | Instance ID (supports multiple) |
| Reset Password | instance-id, password | Instance ID + new password |
| Modify Info | instance-id + (name/description/hostname) | Instance ID + at least one modification |

**Region Parameter Support:**
- Region code: `cn-north-4`
- Full name: `North-China-Beijing4`
- Short name: `Beijing4`, `Guangzhou`, `Shanghai`

## Execution Flow

### Step 1: Check Existing Credentials (Automatic)

**Automatically check environment variables before each execution, no need to ask user:**

```bash
# Check if environment variables exist
if [ -z "$CLOUD_SDK_AK" ] || [ -z "$CLOUD_SDK_SK" ]; then
    echo "❌ No credential environment variables detected, please configure first"
    exit 1
fi

# Test if credentials are valid
python3 scripts/cli.py test
```

**Decision Logic:**

| Credential Status | Connectivity | Next Step |
|------------------|--------------|-----------|
| ✅ Exists | ✅ Connected | Go directly to Step 3 (select operation) |
| ✅ Exists | ❌ Failed | Prompt credentials expired, ask if reconfigure |
| ❌ Not exists | - | Go to Step 2 (configure credentials) |

### Step 2: Configure Credentials (Only When Needed)

**Only ask user in the following situations:**
- Environment variables don't exist
- Credentials have expired

Ask user for:
- **AK (Access Key)**: Huawei Cloud access key
- **SK (Secret Key)**: Huawei Cloud secret key

**After successful configuration, tell user:**

```
✅ Credentials configured successfully!

You can now use the following operations:

1. List Instances - List all Flexus L instances
2. Query Instance Details - View server configuration, status, etc.
3. Traffic Package Query - View traffic package remaining and usage
4. Batch Start - Start multiple servers
5. Batch Stop - Stop multiple servers
6. Batch Reboot - Reboot multiple servers
7. Reset Password - Reset login password
8. Modify Instance Information - Modify instance name, description, hostname

What operation would you like to perform?
```

### Step 3: Select Operation

**After credentials are verified, ask user what operation to perform:**

### Step 4: Execute Operation

**⚠️ Instance Validation (When user provides instance ID/name):**

```bash
python3 {baseDir}/scripts/query_instances.py free-resources
```

- ✅ 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](#finding-server-id) section for guidance.

**⚠️ Important Notes:**

```

**Then append the following, offer automatic query option:**

```
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
```

## Region Support

### Common Region Codes

| Region Code | Region Name |
