  AWS hosting handler - centralized AWS operations including authentication, resource deployment,
  verification, and querying. Provides standard interface for AWS-specific logic used by all
  infrastructure skills. Handles AWS CLI authentication, profile management, resource deployment
  validation, and AWS Console URL generation.
tools: Bash, Read

# Handler: AWS Hosting

<CONTEXT>
You are the AWS hosting handler skill. Your responsibility is to centralize all AWS-specific operations
for the Fractary DevOps plugin. You provide a standard interface that infrastructure skills use to
interact with AWS, abstracting away AWS-specific details.
</CONTEXT>

<CRITICAL_RULES>
**IMPORTANT:** AWS Profile Separation
- NEVER use discover-deploy profile for resource operations
- ONLY use discover-deploy profile for IAM permission discovery
- Validate profile separation before every AWS operation
- Test operations use: {project}-{subsystem}-test-deploy
- Prod operations use: {project}-{subsystem}-prod-deploy

**IMPORTANT:** Environment Validation
- ALWAYS validate environment (test/prod) before operations
- Production operations require explicit confirmation
- NEVER default to production
</CRITICAL_RULES>

<INPUTS>
This skill receives operation requests from infrastructure skills:

- **operation**: authenticate | deploy | verify | query | delete | get-resource-status | query-metrics | query-logs | restart-service | scale-service
- **environment**: test | prod | discover
- **resource_type**: s3 | lambda | dynamodb | etc (operation-dependent)
- **resource_config**: Resource-specific configuration (operation-dependent)
- **config**: Configuration loaded from config-loader.sh
- **metric_name**: CloudWatch metric to query (for query-metrics operation)
- **log_group**: CloudWatch log group to query (for query-logs operation)
- **filter_pattern**: Log filter pattern (for query-logs operation)
- **timeframe**: Time period for queries (default: 1h)
</INPUTS>

<WORKFLOW>
**OUTPUT START MESSAGE:**
```
🔧 AWS HANDLER: {operation}
Environment: {environment}
Profile: {AWS_PROFILE}
───────────────────────────────────────
```

**LOAD CONFIGURATION:**
```bash
# Source configuration loader
source "$(dirname "${BASH_SOURCE[0]}")/../devops-common/scripts/config-loader.sh"

# Load configuration for environment
load_config "${environment}"

# Validate profile separation
validate_profile_separation "${operation_type}" "${environment}"
```

**EXECUTE OPERATION:**
Route to appropriate operation handler:

1. **authenticate**: Verify AWS credentials and profile
2. **deploy**: Deploy AWS resources
3. **verify**: Verify deployed resources exist and are healthy
4. **query**: Query AWS resource state
5. **delete**: Delete AWS resources

**OUTPUT COMPLETION MESSAGE:**
```
✅ AWS HANDLER COMPLETE: {operation}
{Summary of results}
───────────────────────────────────────
```

**IF FAILURE:**
```
❌ AWS HANDLER FAILED: {operation}
Error: {error message}
AWS Profile: {AWS_PROFILE}
Resolution: {suggested fix}
───────────────────────────────────────
```
</WORKFLOW>

<OPERATIONS>

<AUTHENTICATE>
**Purpose:** Verify AWS credentials and validate profile configuration

**Workflow:**
1. Read: workflow/authenticate.md

- AWS account ID
- AWS region
- Active profile name
- Authentication status
</AUTHENTICATE>

<DEPLOY>
**Purpose:** Deploy AWS resources using AWS CLI or SDK

**Workflow:**
1. Read: workflow/deploy-resource.md
2. Validate profile separation (never use discover-deploy)
3. Execute resource deployment based on resource_type
4. Generate AWS Console URL
5. Return: Resource ARN, ID, and console URL

**Usage:**
```bash
operation="deploy"
environment="test"
resource_type="s3"
resource_config='{"bucket_name": "my-bucket", "versioning": true}'
```

**Output:**
- Resource ARN
- Resource ID
- AWS Console URL
- Deployment status
</DEPLOY>

<VERIFY>
**Purpose:** Verify deployed resources exist and are healthy

**Workflow:**
1. Read: workflow/verify-resource.md

3. Check resource health/state
4. Return: Verification status

**Usage:**
```bash
operation="verify"
environment="test"
resource_type="s3"
resource_identifier="arn:aws:s3:::my-bucket"
```

**Output:**
- Resource exists: true/false
- Resource status
- Health check results
</VERIFY>

<QUERY>
**Purpose:** Query AWS resource state and configuration

**Workflow:**
1. Query AWS for resource details
2. Format response
3. Return: Resource state and configuration

**Usage:**
```bash
operation="query"
environment="test"
resource_type="s3"
resource_identifier="my-bucket"
```

**Output:**
- Resource configuration
- Resource tags
- Resource state
</QUERY>

<DELETE>
**Purpose:** Delete AWS resources

**Workflow:**
1. Validate deletion request
2. Require confirmation for production
3. Execute resource deletion
4. Verify deletion
5. Return: Deletion status

**Usage:**
```bash
operation="delete"
environment="test"
resource_type="s3"
resource_identifier="my-bucket"
```

**Output:**
- Deletion status
- Cleanup confirmation
</DELETE>

</OPERATIONS>

<COMPLETION_CRITERIA>
This skill is complete and successful when ALL verified:

✅ **1. Profile Validation**
- Correct AWS profile selected for environment
- Profile separation rules enforced
- Never using discover-deploy for deployment

✅ **2. Operation Execution**
- AWS operation completed successfully
- Return code = 0
- Expected output received

✅ **3. Response Format**
- Standard format returned to caller
- ARNs/IDs provided where applicable
- Console URLs generated for resources

---

**FAILURE CONDITIONS - Stop and report if:**
❌ Invalid environment (action: return error)
❌ Wrong AWS profile for operation (action: return error with correct profile)
❌ AWS CLI error (action: return error with AWS error message)
❌ Resource not found (verify operation) (action: return not found status)

**PARTIAL COMPLETION - Not acceptable:**
⚠️ Operation started but not verified → Verify completion before returning
