Handler: AWS Hosting

<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>

• 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>

LOAD CONFIGURATION:

# 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}

Error: {error message}
AWS Profile: {AWS_PROFILE}
Resolution: {suggested fix}
───────────────────────────────────────

Workflow:

1. Read: workflow/authenticate.md
2. Execute authentication validation
3. Return: Authentication status and account information

Usage:

operation="authenticate"
environment="test"

Output:

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

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:

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>

Workflow:

1. Read: workflow/verify-resource.md
2. Query AWS for resource status
3. Check resource health/state
4. Return: Verification status

Usage:

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>

Workflow:

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

Usage:

operation="query"
environment="test"
resource_type="s3"
resource_identifier="my-bucket"

Output:

• Resource configuration
• Resource tags
• Resource state </QUERY>

Workflow:

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

Usage:

operation="delete"
environment="test"
resource_type="s3"
resource_identifier="my-bucket"

Output:

• Deletion status
• Cleanup confirmation </DELETE>

<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 ⚠️ Resource created but URL not generated → Generate URL before returning </COMPLETION_CRITERIA>

Standard Response Format:

{
  "status": "success|failure",
  "operation": "authenticate|deploy|verify|query|delete",
  "environment": "test|prod",
  "resource": {
    "type": "s3|lambda|etc",
    "arn": "arn:aws:...",
    "id": "resource-id",
    "console_url": "https://console.aws.amazon.com/..."
  },
  "message": "Operation description",
  "error": "Error message if failed"
}

Return to caller: JSON response string </OUTPUTS>

<CONSOLE_URL_GENERATION> Generate AWS Console URLs for resources:

S3 Bucket:

https://s3.console.aws.amazon.com/s3/buckets/{bucket_name}?region={region}

Lambda Function:

https://console.aws.amazon.com/lambda/home?region={region}#/functions/{function_name}

DynamoDB Table:

<ERROR_HANDLING>

<AUTHENTICATION_FAILURE> Pattern: AWS CLI returns "Unable to locate credentials" Action:

1. Check if profile exists: aws configure list-profiles | grep {profile}
2. If missing: Return error with profile setup instructions
3. If exists: Check credentials validity Resolution: "Configure AWS profile: aws configure --profile {profile_name}" </AUTHENTICATION_FAILURE>

<PERMISSION_DENIED> Pattern: AWS returns "AccessDenied" or "UnauthorizedOperation" Action:

1. Extract required permission from error
2. Return error with permission details
3. Suggest using infra-permission-manager to grant permission Resolution: "Missing IAM permission: {permission}. Run with discover-deploy profile to auto-grant." </PERMISSION_DENIED>

<RESOURCE_NOT_FOUND> Pattern: AWS returns "ResourceNotFoundException" or "NoSuchBucket" Action:

1. Return not found status
2. Suggest checking resource name and region Resolution: "Resource not found: {resource_id} in {region}" </RESOURCE_NOT_FOUND>

<RESOURCE_ALREADY_EXISTS> Pattern: AWS returns "ResourceAlreadyExists" or "BucketAlreadyExists" Action:

1. Check if resource belongs to this project (tags)
2. If yes: Return success with existing resource details
3. If no: Return error suggesting different name Resolution: "Resource already exists. Use existing or choose different name." </RESOURCE_ALREADY_EXISTS>
