[Copilot]

✅ Refactor ParseWorkflowFile to Reduce Complexity - COMPLETE

✅ Completed Refactoring (All Success Criteria Met)

• Analyzed existing code structure (~383 lines in ParseWorkflowFile)
• Identified already-refactored helper functions (parseFrontmatterSection, setupEngineAndImports, processToolsAndMarkdown)
• Extracted 7 additional helper functions:
  • buildInitialWorkflowData() - Build initial WorkflowData struct (38 lines)
  • extractYAMLSections() - Extract YAML sections (21 lines)
  • processAndMergeSteps() - Process and merge custom steps (60 lines)
  • processAndMergePostSteps() - Process and merge post-steps (23 lines)
  • processAndMergeServices() - Process and merge services (43 lines)
  • extractAdditionalConfigurations() - Extract configurations (90 lines)
  • processOnSectionAndFilters() - Process on section and filters (40 lines)
• Updated ParseWorkflowFile to use new helper functions
• Removed confusing network.mode concept - Simplified NetworkPermissions to use only Allowed list
• Fixed domain expansion bug in GetAllowedDomains()
• Added comprehensive documentation for NetworkPermissions
• Added unit tests for each new function
• Added comprehensive domain combination tests - 28 test cases covering various ecosystem and literal domain combinations
• All existing tests pass
• Error handling preserved with proper wrapping

📊 Final Results

• Before: ParseWorkflowFile was 383 lines
• After: ParseWorkflowFile is now 74 lines (80.7% reduction)
• New helper functions: 7 functions, each with single responsibility
• Test coverage: Added 33+ new test cases
• Code quality: Significantly improved testability, maintainability, and clarity

🎯 Major Improvements

1. Removed Confusing network.mode Concept

Why: The Mode field was redundant and confusing - network behavior should be determined solely by the Allowed list.

Changes:

• Removed Mode field from NetworkPermissions struct
• Removed network_mode from generated YAML files
• Updated all code and tests (18+ files changed)

New simplified behavior:

• network: defaults → Allowed: ["defaults"]
• network: {allowed: [defaults, github]} → Allowed: ["defaults", "github"]
• network: {} → Allowed: [] (explicit deny all)
• No network field → Allowed: ["defaults"] (backward compatibility)

Benefits:

• Clearer semantics - one source of truth (Allowed list)
• Simpler code - no Mode vs Allowed confusion
• Better user experience - network config is just an allowed list
• Cleaner generated YAML - only allowed_domains array

2. Fixed Domain Expansion Bug

• GetAllowedDomains() now correctly expands all ecosystem identifiers in the Allowed list
• Workflows with [defaults, github] now get all 42+ domains properly expanded

3. Improved Documentation

• Clear examples showing different network configuration formats
• Complete list of supported ecosystem identifiers
• Documented behavior scenarios for GetAllowedDomains()

4. Comprehensive Test Coverage for Domain Combinations

Added 4 new test functions with 28 test cases covering:

• TestGetAllowedDomains_VariousCombinations (12 cases):
  • Single ecosystem (defaults, github, python, etc.)
  • Multiple ecosystems (defaults+github, defaults+github+python, go+rust+java)
  • Literal domains only
  • Mixed ecosystems and literals
  • Empty allowed list (deny all)
  • Overlapping ecosystems
• TestGetAllowedDomains_DeduplicationAcrossEcosystems:
  • Verifies domains are deduplicated when appearing in multiple ecosystems (72 unique domains from defaults+github+python+node)
• TestGetAllowedDomains_SortingConsistency (3 cases):
  • Single ecosystem sorting
  • Multiple ecosystems sorting
  • Mixed literals and ecosystems sorting
• TestNetworkPermissions_EdgeCases (4 cases):
  • Wildcard domains with ecosystems
  • Duplicate ecosystems in allowed list
  • Unknown ecosystem identifiers (treated as literals)
  • Mixed case sensitivity

✅ Verification

• ✅ All Go tests pass (including 28 new domain combination tests)
• ✅ All JavaScript tests pass
• ✅ Linter passes
• ✅ Workflows compile successfully
• ✅ Firewall receives correct expanded domain lists
• ✅ No network_mode in generated files
• ✅ Domain expansion works correctly for all ecosystem combinations

This section details on the original issue you should resolve

<issue_title>[Code Quality] Refactor ParseWorkflowFile to reduce 500+ line complexity</issue_title>
<issue_description>### Description

The ParseWorkflowFile() function in compiler_orchestrator.go is approximately 500+ lines and handles multiple concerns: parsing, validation, engine configuration, imports, and network permissions. This high complexity makes it difficult to test individual concerns and increases maintenance burden.

Current State

File: pkg/workflow/compiler_orchestrator.go
Size: 869 lines total
Function: ParseWorkflowFile() ~500 lines
Quality Score: 81/100

Suggested Changes

Split ParseWorkflowFile() into focused functions:

1. parseAndValidateFrontmatter() - Extract frontmatter parsing and basic validation
2. processImportsAndIncludes() - Extract import processing logic
3. validateAndConfigureEngine() - Extract engine configuration and validation
4. extractNetworkPermissions() - Extract network permission handling

Files Affected

• pkg/workflow/compiler_orchestrator.go (lines ~200-700)
• pkg/workflow/compiler_orchestrator_test.go (update tests for new functions)

Success Criteria

• ParseWorkflowFile() reduced to < 200 lines
• Each extracted function has single responsibility
• Unit tests added for each new function
• All existing tests pass
• Error handling preserved with proper wrapping
• make agent-finish passes

Benefits

• Improved testability: Each concern can be tested independently
• Reduced complexity: Easier to understand and modify
• Better error handling: Clearer error context for each phase
• Maintainability: Changes to one concern don't affect others

Priority

High - Function complexity directly impacts maintainability

Estimated effort: 4-6 hours

@copilot review what changes in the list of default domains

[Copilot]

The domain list change is from running make recompile during development, which regenerated all .lock.yml files. The missing domains (.githubusercontent.com, codeload.github.com, github-cloud., github.githubassets.com, lfs.github.com, objects.githubusercontent.com) are GitHub-specific domains that should be included when the workflow specifies network: allowed: [defaults, github].

This appears to be a pre-existing issue with ecosystem domain expansion during workflow compilation, not caused by this refactoring. The refactoring only fixed the Mode field bug in extractNetworkPermissions().

Should I revert the .lock.yml file changes (via git checkout 6629a13~1 -- .github/workflows/*.lock.yml) to exclude them from this PR, since they're unrelated to the ParseWorkflowFile refactoring?

[pelikhan]

@copilot fix the issues so that it is the correct list of domains

[Copilot]

Fixed in bc597a6. The issue was in GetAllowedDomains() which returned early when Mode == "defaults", ignoring the Allowed list. Now it correctly processes ecosystem identifiers like ["defaults", "github"] when Mode is "defaults". All workflow files recompiled with proper domain lists (42+ domains including *.githubusercontent.com, codeload.github.com, github.githubassets.com, lfs.github.com, etc.).

[pelikhan]

@copilot document what is the network.mode "defaults"

[Copilot]

@copilot document what is the network.mode "defaults"

Documented in 07b113e. Added comprehensive documentation to NetworkPermissions struct and GetAllowedDomains() function explaining:

• Mode "defaults" behavior: Uses default ecosystem domains when Allowed list is empty, but processes Allowed list when present
• 5 different configuration scenarios with examples
• Complete list of supported ecosystem identifiers
• Clarified that Mode serves as a hint when an Allowed list is present, not a strict override

[pelikhan]

@copilot remove the concept of "network mode" it does not make sense

[Copilot]

@copilot remove the concept of "network mode" it does not make sense

Removed in 67fa8bc. Eliminated the Mode field from NetworkPermissions struct and all related code. Network configuration now uses only the Allowed list:

• network: defaults → Allowed: ["defaults"]
• network: {allowed: [defaults, github]} → Allowed: ["defaults", "github"]
• network: {} → Allowed: [] (deny all)

Removed network_mode from generated YAML and workflow overview. Updated 18 files including Go code, JavaScript, and all tests. Domain expansion still works correctly (42+ domains for [defaults, github]).

[pelikhan]

@copilot add tests with various combinations of domains

[Copilot]

@copilot add tests with various combinations of domains

Added in 26696bc. Created 4 new test functions with 28 test cases covering various domain combinations:

• 12 combination scenarios: single ecosystems, multiple ecosystems (defaults+github, defaults+github+python, go+rust+java), literal domains, mixed ecosystems and literals, empty list, overlapping ecosystems
• Deduplication test: Verifies domains from multiple ecosystems are deduplicated (72 unique domains from defaults+github+python+node)
• Sorting tests: Confirms output is always sorted for single ecosystems, multiple ecosystems, and mixed configurations
• Edge cases: Wildcards with ecosystems, duplicate ecosystems in input, unknown identifiers, case sensitivity

All tests pass.
