5-13: Consider adding input validation.While the initialization looks good, consider adding validation for:
- Ensuring name is not empty or nil
- Validating tags format if present (should be a hash/dictionary)
Here's a suggested implementation:
def initialize(name:, description: nil, tags: nil) super() + raise ArgumentError, "Name cannot be empty" if name.nil? || name.empty? + raise ArgumentError, "Tags must be a hash" if tags && !tags.is_a?(Hash) + @name = name @description = description @tags = tags end
15-21: Add documentation for the Terraform configuration format.Consider adding documentation comments to explain the expected Terraform configuration format that will be generated. This would help developers understand the output structure.
+ # Generates Terraform configuration for a Control Plane agent + # Example output: + # resource "cpln_agent" "agent_name" { + # name = "agent_name" + # description = "Optional description" + # tags = { key = "value" } + # } def to_tfspec/core/terraform_config/agent_spec.rb (3)
5-7: Consider adding test coverage for invalid configurations.The current setup only tests the happy path. Consider adding test cases for:
- Missing required attributes
- Invalid tag formats
- Empty or nil values
Example:
context "with invalid configuration" do context "when name is missing" do let(:options) { { description: "desc", tags: {} } } it "raises an error" do expect { config.to_tf }.to raise_error(ArgumentError) end end end
8-18: Add test cases for tag edge cases.Consider adding test cases for:
- Empty tags hash
- Tags with special characters
- Maximum number of tags (if there's a limit)
Example:
context "with special characters in tags" do let(:options) do { name: "agent-name", description: "description", tags: { "special@tag" => "value-with-spaces" } } end it "properly escapes special characters" do # Add expectations end end
19-32: Consider making the assertions more robust.The current exact string matching might be too brittle. Consider:
- Using JSON/HCL parsing to compare the structural equality instead of exact string matching
- Adding assertions for individual attributes
Example approach:
it "generates valid configuration" do # Parse the generated output as HCL parsed = parse_hcl(generated) # Test individual attributes expect(parsed.dig("resource", "cpln_agent", "agent-name", "name")).to eq("agent-name") expect(parsed.dig("resource", "cpln_agent", "agent-name", "description")).to eq("agent description") expect(parsed.dig("resource", "cpln_agent", "agent-name", "tags")).to eq({ "tag1" => "true", "tag2" => "value" }) end

1-5: LGTM! Well-structured class definition.
The class follows Ruby conventions and is properly organized within the TerraformConfig module.
15-21: Verify the cpln_agent resource type exists in Terraform provider.
The code generates a cpln_agent resource type. Let's verify its existence and proper usage in the Terraform provider.
✅ Verification successful
The previous search might have been too restrictive. Let's broaden our search to understand the context better and find any provider or resource type definitions.
Let's examine the provider configuration and test files to understand if this is a custom provider and how it's being used.
The cpln_agent resource type is valid and properly configured
The verification shows that:
- The
cpln_agentresource type is part of thecontrolplane-com/cplnprovider, which is properly configured inrequired_providers.tf - The provider source is set to "controlplane-com/cpln" with version "~> 1.0"
- The test file confirms the expected Terraform configuration format for the resource

1-4: LGTM! File setup follows best practices.
lib/core/terraform_config/generator.rb (2)
5-5: LGTM! Addition of 'agent' to supported template kinds.
The change is consistent with the PR objectives and maintains backward compatibility.
107-109: Verify completeness of agent configuration parameters.
The agent_config_params method only extracts basic attributes (name, description, tags), while other template kinds (like gvc_config_params, workload_config_params) extract additional spec-specific parameters. Please verify if there are any agent-specific parameters that should be included.
Let's check the agent template structure and requirements:
✅ Verification successful
Based on the results, I can see that the Agent class in lib/core/terraform_config/agent.rb only has three attributes: name, description, and tags. These exactly match the parameters being extracted by the agent_config_params method. Let me verify if there are any other required parameters by checking the base class and related specs.
Based on the comprehensive verification results, I can now generate the final response:
The agent_config_params implementation is correct and complete
The method correctly extracts all required parameters for agent configuration. This is verified by:
- The
Agentclass implementation showing exactly these three attributes: name, description, and tags - The agent specs demonstrating these are the only parameters used in testing
- No additional required parameters found in the base class

26-26: LGTM! Addition of 'agents' path aligns with PR objectives.
The addition of 'agents' to TEMPLATE_CONFIG_PATHS correctly extends test coverage for the new agent template type support.
Let's verify the integration with related changes:
✅ Verification successful
✅ Integration verified: Agent template type is fully supported
The verification confirms all necessary components are in place:
- Agent class implementation exists in
lib/core/terraform_config/agent.rb - Agent type is included in
SUPPORTED_TEMPLATE_KINDSin the generator - The addition of 'agents' path in test configuration aligns with the implementation

534-561: LGTM! Well-structured test coverage for agent template.
The test context for the agent template kind is well-implemented and follows the established patterns in the file. It effectively validates:
- The correct output filename
- The proper instance type
- The accurate transfer of template fields to the configuration
The use of aggregate_failures ensures comprehensive error reporting.
536-543: Consider expanding test coverage for agent templates.
The current test covers basic fields, but consider adding test cases for:
- The 'type' field mentioned in the PR objectives
- Any agent-specific configuration fields
- Edge cases (e.g., missing required fields, validation scenarios)
Let's check if there are any agent-specific fields we should test:
✅ Verification successful
Test coverage for agent templates appears sufficient
Based on the implementation in agent.rb and existing tests, the current test coverage is adequate because:
- The 'type' field mentioned in PR objectives appears to be a migration detail, not a required field in the actual agent configuration
- All supported fields (name, description, tags) are already covered in both the implementation and tests
- The implementation shows these are the only fields supported, with proper handling of optional fields
- The agent implementation in
lib/core/terraform_config/agent.rbmatches exactly what's being tested - Both required (
name) and optional (description,tags) fields are properly tested - The test verifies the correct Terraform resource generation
